When the sealing cover is closed during use, the sealing cover is opened when lubricating oil 13 needs to be added, and the lubricating oil is added into the oil tank 9 through the oil filling port 19. The atomizing pipe 12 is fixed on the top of the inner wall of the oil tank 9, and the atomizing pipe 12 is not contacted with the lubricating oil 13. One end of the atomizing pipe 12 is provided with a high-pressure air pipe joint 15, and the other end of the atomizing pipe 12 is provided with an oil injection pipe joint 16. The high-pressure air pipe connector 15 and the oil spraying pipe connector 16 are externally provided with external threads, the high-pressure air pipe connector 15 is connected with a high-pressure air pipe 10, and the oil spraying pipe connector 16 is connected with an oil spraying pipe 11.

As shown in fig. 1, the electronic control module includes a proximity switch 7, an electric cabinet 6, and an electromagnetic valve 5, the proximity switch 7, the electric cabinet 6, and the electromagnetic valve 5 are connected by a signal line 21, the electromagnetic valve 5 is installed on the high-pressure air pipe 10, and the electromagnetic valve 5 is used for controlling the on-off of the air flow in the high-pressure air pipe 10. Proximity switch 7 sets up the one side at pulley 8, is provided with the piece that triggers that is used for triggering proximity switch 7 on pulley 8, and when the piece that triggers on pulley 8 rotated and is close to proximity switch 7, proximity switch 7 signals to change this signal into electric current transmission to solenoid valve 5 through the electric cabinet, solenoid valve 5 switches the inside on-off state, thereby the break-make of air current in the control high-pressure gas pipe 10. The tail end of the oil spraying pipe 11 is opposite to the bearing of the pulley 8 and is used for spraying oil mist to lubricate the bearing of the pulley 8.

As shown in fig. 1, 2 and 3, the high pressure gas pipe 10 is provided with a water-dividing filter 2, and the water-dividing filter 2 is adapted to filter water vapor in the gas flow in the high pressure gas pipe 10. The high-pressure air pipe 10 is also provided with a main valve 1, and the main valve 1 is suitable for controlling the on-off of the air flow in the high-pressure air pipe 10. The high-pressure air pipe 10 is also provided with a pressure reducing valve 3 and a pressure gauge 4, the pressure reducing valve 3 and the pressure gauge 4 form a pressure feedback and pressure stabilizing system, when the pressure gauge 4 monitors that the air pressure in the high-pressure air pipe 10 is higher, the pressure reducing valve 3 is started to reduce the air flow in the high-pressure air pipe 10, and the pressure reducing valve 3 stops working until the internal pressure is reduced to a preset value, so that the stability of the pressure in the high-pressure air pipe 10 is ensured.

As shown in fig. 2, 4, and 5, an atomizing unit for sucking and atomizing the lubricant oil 13 in the oil tank 9 is provided inside the atomizing pipe 12. The atomizing unit includes a plurality of atomizing chambeies 18 that set up inside the atomizer 12 casing, and a plurality of atomizing chambeies 18 use the axis of atomizer 12 to be the circumference array as the center, are convenient for evenly inhale the inner chamber of atomizer 12. Specifically, six atomizing units are provided inside the atomizing tube 12. The inhaled lubricating oil is instantly atomized by six uniformly arranged atomizing units through vacuum negative pressure. The inside of the atomizer chamber 18 is provided with a check valve 20, and the check valve 20 allows only the lubricant oil 13 to enter the atomizer tube 12 from the atomizer chamber 18 side without flowing backward. One end of the atomizing chamber 18 communicates with the inner chamber of the atomizing tube 12. The atomizing chamber 18 is inclined with respect to the central axis of the atomizing tube 12. The other end of the atomizing chamber 18 is connected with an oil suction pipe joint 17, and the oil suction pipe joint 17 is arranged on the end surface of the atomizing pipe 12.

Thereby communicating the atomizing chamber 18 with the suction pipe 14 and introducing the lubricating oil 13 into the inner chamber of the atomizing pipe 12 through the suction pipe 14.

The pipe diameter of the oil suction pipe 14 is small, when high-pressure airflow is introduced into the high-pressure air pipe 10, because the insertion angle of the atomization cavity 18 is the same as the flow direction of the airflow in the atomization pipe 12, when the high-pressure airflow rapidly flows through the port above the atomization cavity 18, the air pressure in the atomization cavity 18 is sucked away, so that the air pressure near the port above the atomization cavity 18 is relatively low, and vacuum suction force is generated in the atomization cavity 18 and is transmitted into the oil suction pipe 14, the air pressure in the oil suction pipe 14 is smaller than the external air pressure, so that the lubricating oil 13 enters along the oil suction pipe 14 and enters into the atomization cavity 18, because the pipe diameter of the oil suction pipe 14 is small, the amount of oil entering the atomization cavity 18 is small, and the air pressure in the atomization cavity 18 is low, oil drops sucked into the atomization cavity 18 are instantly atomized under low pressure and are sprayed out along the oil injection pipe 11 along with the high-pressure airflow in the atomization pipe 12.

The working principle is as follows: when the trigger piece on pulley 8 rotates and is close to proximity switch 7, proximity switch 7 signals of telecommunication, and convert this signal into current transfer to solenoid valve 5 through the electric cabinet, solenoid valve 5 opens, high-pressurepipe 10 air current can smoothly circulate, when high-pressurepipe passes through atomizing pipe 12, near atmospheric pressure of 18 top ports in atomizing chamber is lower relatively, thereby make and produce vacuum suction in atomizing chamber 18, thereby in inhaling atomizing chamber 18 with lubricating oil, because atomizing chamber 18 top port atmospheric pressure is lower, a small amount of inhaled lubricating oil is atomized in the twinkling of an eye, and along spouting oil pipe 11 blowout along the high-pressurepipe in atomizing pipe 12, spout oil pipe 11 end and just to pulley 8's bearing, thereby lubricate pulley 8's bearing. The self-lubricating oil sprayer for the pulley bearing does not need manual operation, and can realize automatic lubrication of the pulley bearing at high frequency intervals.
