Technical Field

The invention belongs to the technical field of oil distributors, and particularly relates to an integral oil distributor.

Background

The traditional oil distributor comprises an oil distribution disc and a guide wheel shaft, wherein the oil distribution disc of the traditional oil distributor is in interference fit press-fitting connection with the guide wheel shaft. The interference fit has the quality defect of hydraulic leakage caused by the reduction of the sealing performance of the oil distributor due to improper interference of the matching surface or surface damage of the matching surface in the processes of manufacturing and press mounting of parts. In addition, the interference magnitude has a large influence on the performance of the oil distribution disc, when the interference magnitude is too large, the plane of the oil distribution disc is deformed due to matching, and when the interference magnitude is too small, the strength of the oil separator for resisting torque is reduced. Therefore, in order to ensure proper interference of the matching surface, the dimensional accuracy and the surface roughness of the matching part of the oil distribution disc and the guide wheel shaft have strict requirements, the quality requirement of the manufacturing and press-fitting process is high, and the manufacturing cost is increased. In addition, the oil distribution disc is of a cake-shaped structure and is heavy.

Patent No. CN109681619A, the patent name "an oil distribution system and an oil distribution disc assembly of a gearbox"; the oil distribution system of the gearbox comprises the gearbox and an oil distribution disc assembly, wherein the oil distribution disc assembly comprises an oil distribution disc and a disc shaft, the oil distribution disc comprises a sleeve and a disc body, and the disc shaft is press-mounted on the oil distribution disc; the oil distribution disc is arranged on a shell of the gearbox, and the sleeve is inserted into a control cavity of a clutch in the gearbox; the disc body is provided with a first oil duct, the sleeve is provided with a first oil hole, the press-fitting surface of the disc shaft is provided with a first oil groove, and the first oil duct and the first oil hole are communicated with the first oil groove; the first oil duct is provided with a first oil port for oil inlet. The present invention still has high production requirements.

Disclosure of Invention

The invention aims to overcome the defects of high processing requirement and heavy weight in the prior art, and provides an integral oil distributor which is simple to process and light in weight.

In order to achieve the purpose, the invention adopts the following technical scheme:

the integral oil distributor comprises an oil distribution disc, a guide wheel shaft positioned in the middle of the oil distribution disc, a plurality of oil ducts positioned in the oil distribution disc, oil inlet holes positioned at the end parts of the oil ducts, and bolt holes positioned at the edge of the oil distribution disc, wherein the oil distribution disc and the guide wheel shaft are of an integrally formed structure, the oil distribution disc is provided with a plurality of lightening holes, the oil distribution disc is provided with reinforcing ribs at corresponding positions of the oil ducts, the oil ducts are positioned in the reinforcing ribs, the oil distribution disc comprises an annular framework and a second reinforcing rib, one end of the second reinforcing rib is fixedly connected onto the framework, the other end of the second reinforcing rib is fixedly connected onto the guide wheel shaft, the framework, the second reinforcing rib and the. The oil distribution disc and the guide wheel shaft are integrally formed, in order to meet the requirement that the oil duct of the integral oil distributor is communicated, a five-axis machining center and a casting technology are combined to communicate the oil duct, and meanwhile, the machining efficiency is improved (each oil duct is machined by one-time clamping); and part of the oil ducts are communicated by being designed into inclined holes (processed by a five-axis machining center), and part of the oil ducts are communicated by being designed into a casting structure, so that all the oil ducts are ensured to meet the use requirements of products. The weight of the lightening hole is reduced by more than 30 percent. The reinforcing ribs improve the rigidity, strength and stability of the invention, and the second reinforcing ribs improve the strength, rigidity and stability of the invention.

Preferably, the oil distribution disc is provided with the bolt holes at the positions corresponding to the oil inlet holes. The bolt hole is arranged at the edge of the oil distribution disc, and the oil inlet hole ensures the stability of the transmission oil, so the bolt hole is arranged near the oil inlet hole.

Preferably, the oil distribution disc and the guide wheel shaft are made of nodular cast iron. The strength requirement is met by utilizing a high-strength ductile iron casting material, a guide wheel shaft in the prior art is made of ordinary carbon steel No. 45 (the breaking strength is 600MPa, and the yield strength is 355 MPa), and the ductile iron QT600-3 (the breaking strength is 600MPa and the yield strength is 370 MPa) is designed and used in the embodiment and can completely meet the use requirement.

Preferably, the second ribs and a part of the ribs are radially distributed around the axis of the idler shaft. The circumferential strength of the guide wheel shaft is ensured to be uniform.

Preferably, a fixing bolt used for fixedly connecting the oil distribution disc on the gearbox is inserted in the bolt hole, the fixing bolt comprises a stud and a bolt head, the cross section of the bolt head is circular, a groove used for accommodating the bolt head is arranged in the position, corresponding to the bolt hole, of the oil distribution disc, an annular slot is formed in the inner side wall of the groove, a wrench inserting groove used for inserting a wrench is formed in one side, away from the stud, of the bolt head, two through sliding grooves are formed in the inner side wall of the wrench inserting groove, one end of each sliding groove faces the wrench groove, the other end of each sliding groove faces the slot, an inserting piece is connected in each sliding groove in a sliding mode and is symmetrical with the circle center of the cross section of the bolt head, a wire collecting groove parallel to the axis of the stud is formed in the groove bottom of the wrench groove, a spring and a pull wire are arranged between the two inserting pieces, the pull wire corresponds to the take-up groove. When the spanner is taken out, the inserted sheet is embedded into the slot, and when the fixing bolt is not flexible, the inserted sheet prevents the bolt head from moving towards the direction of the moving stud, so that the fixing bolt is prevented from being flexible.

Preferably, the cross section of the wrench groove is a regular hexagon. And rotating the fixing bolt by adopting an inner hexagonal wrench.

Preferably, the bolt head is matched with the groove, an annular anti-theft and anti-loosening groove is formed between the bolt head and the groove, and the groove width of the anti-theft and anti-loosening groove is 80% -90% of the thickness of the inserting sheet. At the moment, if someone wants to use a common socket head cap wrench to dismount the oil distributor privately, the inserting piece is always in the slot, when the fixing bolt is rotated, the sliding groove moves upwards, the sliding groove is staggered with the slot, the inserting piece is bent, the inserting piece is deformed into an S shape, the middle part of the inserting piece is embedded into the anti-theft anti-loosening groove, the groove width of the anti-theft anti-loosening groove is 80% -90% of the thickness of the inserting piece, the inserting piece can be clamped in the anti-theft anti-loosening groove, the socket head cap wrench cannot continuously rotate the fixing bolt, the fixing bolt cannot be screwed out, and therefore the anti-theft effect of the oil distributor is. In a similar way, when the fixing bolt is loosened, the inserting pieces also play a role in preventing looseness.

The invention has the beneficial effects that: the invention provides an integral oil distributor which is simple to process and light in weight. In addition, the anti-theft and anti-loosening functions can be realized.
