The outlet of the hydraulic pump is communicated with the inlet of a third reversing valve, the outlet of the third reversing valve is communicated with the inlet of a first one-way valve, the outlet of the first one-way valve is communicated with a first injection hole, the outlet of the third reversing valve is communicated with a second one-way valve, the outlet of the second one-way valve is communicated with a second injection hole, and the bearing on the cylindrical bump and the bearing on the body can be cleaned simultaneously by conducting the third reversing valve. Since the bearing cleaning seat is located in the cleaning tub, the cleaning liquid that has cleaned the bearing can be collected by the cleaning tub. Through setting up gas holder, first valve and second valve, the import intercommunication of gas holder and first valve, the export and the first filling hole intercommunication of first valve, the gas holder still with the import intercommunication of second valve, the export and the second filling hole intercommunication of second valve, after finishing wasing through the washing liquid, can open first valve or second valve, weather the bearing through gas. The problem of low manual cleaning efficiency is avoided.

Illustratively, the cleaning fluid may be gasoline or diesel. The stains on the bearings are usually lubricants which are mixed with impurities and go bad, belong to organic matters, and are cleaned by gasoline or diesel oil, so that the stains on the bearings can be better dissolved, and the cleaning effect is improved.

According to the number and the position of the bearings arranged on the bearing cleaning seat 41, the first direction valve 21, the second direction valve 22 and the third direction valve 23 can be selectively opened, for example, if only the bearings are sleeved on the cylindrical projection 412 for cleaning, only the first direction valve 21 can be controlled to be opened, the second direction valve 22 and the third direction valve 23 can be kept to be closed, and only the first valve 51 can be opened and the second valve 52 can be kept to be closed during blow-drying. If only the main body 411 is covered with the bearing for cleaning, only the second direction valve 22 can be controlled to be turned on, the first direction valve 21 and the third direction valve 23 can be kept off, and only the second valve 52 can be opened and the first valve 51 can be kept off during blow-drying. If bearings are sleeved on the cylindrical projection 412 and the body 411, the third direction valve 23 can be controlled to be on, the first direction valve 21 and the second direction valve 22 can be kept off, and the first valve 51 and the second valve 52 can be opened during drying. Of course, in the case that the bearings are sleeved on both the cylindrical protrusion 412 and the body 411, only the first valve 51 or the second valve 52 may be selectively opened, so that only one of the bearings is cleaned.

As shown in fig. 1, the first direction valve 21, the second direction valve 22 and the third direction valve 23 may be two-position two-way direction valves having the same structure, and the two-position two-way direction valve may be in two states, such as the first direction valve 21, if the first direction valve 21 is in the first state, the inlet and the outlet of the first direction valve 21 are connected, and if the first direction valve 21 is in the second state (i.e., the state shown in fig. 1), the first direction valve 21 is disconnected.

The first valve 51 and the second valve 52 can be ball valves, and the ball valves are convenient to open and operate and good in sealing performance.

As shown in fig. 1, the bearing cleaning system may further include a settling tank 70. The settling tub 70 communicates with the bottom of the washing tub 42. The washing tub 42 can prevent the washing liquid from splashing during the washing process, and the waste liquid generated during the washing process can flow into the precipitation tub 70 through the washing tub 42 to be stored. After the sedimentation, the waste liquid in the sedimentation tank 70 can be collectively treated, for example, recovered and reused.

The cleaning barrel 42 may include a barrel body and a barrel cover, and after the barrel cover is removed and the bearing is placed on the bearing cleaning seat 41, the barrel cover is covered to prevent the cleaning liquid from splashing out of the barrel body.

Fig. 2 is a top view of a bearing cleaning seat provided in an embodiment of the present disclosure. The dotted line in fig. 2 is a schematic diagram of a partial movement trajectory of the discharged cleaning liquid in a plan view. As shown in fig. 2, the spraying direction of the first spraying hole 41a may form an acute angle with the end surface of the body 411 and be perpendicular to the radial direction of the body 411, and the spraying direction of the second spraying hole 41b may form an acute angle with a side surface of the positioning outer flange 413 close to the cylindrical protrusion 412 and be perpendicular to the radial direction of the body 411.

In fig. 2, when the bearing is cleaned, the cleaning liquid discharged from the first nozzle hole 41a and the second nozzle hole 41b generates a tangential force to the bearing, and the bearing rotates by the tangential force, and for example, when the cleaning liquid is discharged in the direction shown in fig. 2, the bearing rotates counterclockwise in fig. 2, and the cleaning effect can be improved. After cleaning, the first direction valve 21, the second direction valve 22 and the third direction valve 23 are kept closed, at least one of the first valve 51 and the second valve 52 is opened, and when the bearing is dried, the airflow sprayed from the first spray hole 41a and the second spray hole 41b generates tangential force on the bearing, so that the bearing rotates under the action of the airflow, and the drying effect is better.

The movement locus of the cleaning liquid sprayed from the first spray holes 41a and the movement locus of the cleaning liquid sprayed from the second spray holes 41b in fig. 2 are only illustrated schematically, in other possible implementations, the movement locus of the cleaning liquid sprayed from the first spray holes 41a and the movement locus of the cleaning liquid sprayed from the second spray holes 41b may be opposite to those in fig. 2, that is, the movement locus of the cleaning liquid sprayed from the plurality of first spray holes 41a and the movement locus of the cleaning liquid sprayed from the plurality of second spray holes 41b in fig. 2 are both counterclockwise, and in other possible implementations, the movement locus of the cleaning liquid sprayed from the plurality of first spray holes 41a and the movement locus of the cleaning liquid sprayed from the plurality of second spray holes 41b may be both clockwise. In addition, the movement locus of the cleaning liquid discharged from the plurality of first nozzle holes 41a and the movement locus of the cleaning liquid discharged from the plurality of second nozzle holes 41b may be opposite directions, that is, the movement locus of the cleaning liquid discharged from the plurality of first nozzle holes 41a is counterclockwise, the movement locus of the cleaning liquid discharged from the plurality of second nozzle holes 41b is clockwise, or the movement locus of the cleaning liquid discharged from the plurality of first nozzle holes 41a is clockwise, and the movement locus of the cleaning liquid discharged from the plurality of second nozzle holes 41b is counterclockwise.

The plurality of first nozzle holes 41a may be arranged at equal angular intervals in the circumferential direction of the cylindrical protrusion 412, and the plurality of second nozzle holes 41b may be arranged at equal angular intervals in the circumferential direction of the body 411, so that the bearing is more uniformly stressed, and the bearing rotates more stably in the cleaning and drying processes.

Illustratively, the body 411 may have 4 first nozzle holes 41a, and the positioning outer flange 413 may have 4 second nozzle holes 41 b. In other possible implementations, other numbers of first nozzle holes 41a and second nozzle holes 41b may be provided, for example, 3 first nozzle holes 41a and 3 second nozzle holes 41 b.

The number of the first nozzle holes 41a and the number of the second nozzle holes 41b may be the same or different. The number of the second nozzle holes 41b may be greater than that of the first nozzle holes 41a, and since the diameter of the bearing sleeved on the body 411 is greater than that of the bearing sleeved on the cylindrical protrusion 412, and the bearing capacity of the shaft with a larger diameter is generally greater, a greater number of the second nozzle holes 41b may generate a greater force on the bearing, so that the bearing can rotate during the cleaning and drying processes.

As shown in fig. 1, the bearing cleaning seat 41 may have a first cavity 41m communicating with the first injection hole 41c and a second cavity 41n communicating with the second injection hole 41d therein, and the plurality of first nozzle holes 41a may communicate with the first cavity 41m and the plurality of second nozzle holes 41b may communicate with the second cavity 41 n. The first nozzle holes 41a are communicated with each other through the first cavity 41m to equalize the pressures of the first nozzle holes 41a, and the second nozzle holes 41b are communicated with each other through the second cavity 41n to equalize the pressures of the second nozzle holes 41 b. Therefore, the bearing can be stressed more evenly and rotate more stably.

The bearing cleaning seat 41 can be a metal structural part which is high in strength, not easy to deform and long in service life.

The diameter of the body 411 of the bearing cleaning seat 41 and the diameter of the cylindrical bump 412 can be set according to the inner diameter of a bearing to be cleaned, and the bearing cleaning seat 41 with various sizes can be set for replacement and cleaning of various bearings with different inner diameters.

As shown in fig. 1, the bearing cleaning system may further include a third check valve 33 and an accumulator 15, an inlet of the third check valve 33 is communicated with an outlet of the hydraulic pump 12, an outlet of the third check valve 33 is communicated with an inlet of the first direction changing valve 21, an inlet of the second direction changing valve 22, and an inlet of the third direction changing valve 23, respectively, and the accumulator 15 is communicated with an outlet of the third check valve 33.

The accumulator 15 can be used as an auxiliary power source to provide certain system pressure, the third one-way valve 33 enables the system to be conducted only in one direction, the cleaning liquid is prevented from flowing backwards, and the pressure of the accumulator 15 can be prevented from acting on the hydraulic pump 12.

As shown in fig. 1, the bearing cleaning system may further include a relief valve 18, and as shown in fig. 1, an inlet and a pilot oil port of the relief valve 18 may communicate with an outlet of the hydraulic pump 12, and an outlet of the relief valve 18 may communicate with the oil tank 11.

As shown in fig. 1, a cleaning solution filter 19 may be further connected between the outlet of the hydraulic pump 12 and the inlet of the third check valve 33. Certain impurities may exist in the cleaning liquid, and the cleaning liquid filter 19 can filter the cleaning liquid sent by the hydraulic pump 12, so that the problem that the impurities in the cleaning liquid cause blockage of a bearing cleaning system and damage to the bearing cleaning system is avoided.

As shown in FIG. 1, the bearing cleaning system may also include a fourth check valve 34 and a fifth check valve 35. An inlet of the fourth check valve 34 communicates with an outlet of the first direction changing valve 21, an outlet of the fourth check valve 34 communicates with the first injection hole 41c, an inlet of the fifth check valve 35 communicates with an outlet of the second direction changing valve 22, and an outlet of the fifth check valve 35 communicates with the second injection hole 41 d.

The fourth check valve 34 and the fifth check valve 35 are provided to prevent the reverse flow of the cleaning liquid, and when the first direction switching valve 21 and the second direction switching valve 22 are closed and the third direction switching valve 23 is opened, the fourth check valve 34 and the fifth check valve 35 prevent the high pressure in the pipe from being applied to the outlet of the first direction switching valve 21 and the outlet of the second direction switching valve 22.

As shown in FIG. 1, the bearing cleaning system may also include a pneumatic fitting 16 and a sixth one-way valve 36. The inflation fitting 16 may be in communication with an inlet of a sixth one-way valve 36, and an outlet of the sixth one-way valve 36 may be in communication with the air reservoir 13.

The gas tank 13 can be conveniently filled with high-pressure gas by providing the gas charging connector 16, and the sixth check valve 36 can prevent the gas in the gas tank 13 from leaking through the gas charging connector 16.

Optionally, the bearing cleaning system may further comprise an air filter 17. The air filter 17 may communicate between the air charging connector 16 and the inlet of the sixth one-way valve 36.

The air filter 17 is provided to filter the gas filled in the gas container 13, thereby preventing impurities from entering the gas container 13.

As shown in fig. 1, the bearing cleaning system may further include a hydraulic cylinder 61, a fourth directional valve 24, and a fluid reservoir 62 for containing a lubricant. The outlet of the hydraulic pump 12 may be in communication with the first port a of the fourth direction valve 24, the second port B of the fourth direction valve 24 may be in communication with the rod chamber of the hydraulic cylinder 61, the rodless chamber of the hydraulic cylinder 61 may be in communication with the third port C of the fourth direction valve 24, and the fourth port D of the fourth direction valve 24 may be in communication with the oil tank 11. The piston rod 611 of the hydraulic cylinder 61 has a bearing connection structure for placing a bearing, and the piston rod 611 of the hydraulic cylinder 61 is located right above the oil supply cylinder 62.

After the bearing is cleaned and dried, the cleaning barrel 42 can be opened, the bearing is taken down from the bearing cleaning seat 41, after the cleaning effect is checked to be qualified, the bearing can be placed on the bearing connecting structure, the piston rod 611 of the hydraulic cylinder 61 is controlled to extend through the fourth reversing valve 24, so that the bearing is immersed into the oil supplementing cylinder 62 containing the lubricant, after the bearing is fully lubricated, the piston rod 611 of the hydraulic cylinder 61 is controlled to retract through the fourth reversing valve 24, and the shaft bushing is taken out of the oil supplementing cylinder 62. The lubricated bearing can be directly installed for use.

The lubricant contained in the oil supply cartridge 62 may be oil or grease as it is uniformly squeezed out of the bearing pockets indicating that the bearing is sufficiently lubricated.

As shown in fig. 1, the fourth direction valve 24 may be a four-position two-way direction valve, which has two states, and if the fourth direction valve 24 is in the first state (i.e., the state shown in fig. 1), the first port a of the fourth direction valve 24 is communicated with the second port B of the fourth direction valve 24, and the third port C of the fourth direction valve 24 is communicated with the fourth port D of the fourth direction valve 24. If the fourth direction valve 24 is in the second state, the first port a of the fourth direction valve 24 is communicated with the third port C of the fourth direction valve 24, and the second port B of the fourth direction valve 24 is communicated with the fourth port D of the fourth direction valve 24.

During the cleaning and drying process, the fourth directional control valve 24 may be in the first state, so that the piston rod 611 of the hydraulic cylinder 61 is kept retracted by the pressure of the rod chamber.

Fig. 3 is a schematic structural diagram of a bearing connection structure provided in an embodiment of the present disclosure. As shown in fig. 3, the bearing coupling structure may include a support shaft 631 coaxially coupled to the piston rod 611 of the hydraulic cylinder 61, a first stopper 632 coaxially coupled to one end of the support shaft 631 coupled to the piston rod 611 of the hydraulic cylinder 61, and a second stopper 633 detachably coupled to the other end of the support shaft 631.

When the bearing is placed, the second retaining ring 633 can be detached from the support shaft 631, the bearing is sleeved on the support shaft 631, and then the second retaining ring 633 is coaxially connected to the support shaft 631, so that the first retaining ring 632 and the second retaining ring 633 can limit the bearing and prevent the bearing from falling off from the support shaft 631. During the process of lubricating the bearing, the first blocking ring 632 may provide pressure to press the bearing into the oil supply cylinder 62, and the second blocking ring 633 may support the bearing and pull the bearing out of the oil supply cylinder 62 when the piston rod 611 of the hydraulic cylinder 61 is controlled to retract through the fourth directional control valve 24.

For example, the first baffle ring 632 may be welded to the support shaft 631, and the second baffle ring 633 may be threadedly coupled to the support shaft 631.

The length of the support shaft 631 may be greater than the axial length of the plurality of bearings, so that the plurality of bearings may be mounted on the support shaft 631 at a time for lubrication.

As shown in fig. 1, the bearing cleaning system may also include a pressure relief valve 14. An inlet of the pressure reducing valve 14 is communicated with an outlet of the hydraulic pump 12, and an outlet of the pressure reducing valve 14 is communicated with the first port a of the fourth direction valve 24. By providing the pressure reducing valve 14, the pressure in the hydraulic cylinder 61 is reduced, and the extension and contraction of the piston rod 611 of the hydraulic cylinder 61 are made more smooth.

The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
