This kind of filtering mechanism is usually located at the outlet of the oil injection pump and can block particles, impurities and other pollutants to ensure that the lubricating medium conveyed to the equipment is clean. The design of the filtering mechanism can vary depending on the application, but its basic principle is to filter out the impurities and particles in the lubricating medium through a filter before conveying the lubricating medium to protect the normal operation of the equipment.

Connecting flanges are arranged at the ports of the oil inlet pipe and the oil outlet pipe. A filtering component is arranged on the side wall of the driving wheel rotating shaft and can filter the oil entering the pump body from the oil outlet pipe. A guide groove is arranged on the inner wall of the oil inlet pipe and the end of the filter screen extends into the guide groove. The pump body adopts a flange connection method, which can not only improve efficiency, save installation accessories, but also not easily leak, greatly facilitating the installation process. And a filter screen is obliquely inserted at the port of the oil inlet pipe, so as to filter the oil entering the pump body, solving the problems that the pump is stuck due to impurities in the oil during use, and the seal is easily damaged and leaked, and prolonging the service life of the pump.

A housing 6 is sleeved outside the driving shaft 2. A rotating shaft 4 is arranged inside the housing 6. A driven gear 5 is fixedly connected to the outside of the rotating shaft 4. With high manufacturing precision and small clearance during meshing, the transmission precision of the driven gear 5 is higher than that of other transmission methods, and it can ensure the accuracy and stability of the output shaft. Pipes 7 are fixedly connected to both the left and right sides of the housing 6. A first flange 9 is fixedly connected to the left side of the left pipe 7. One of the oil pipes is fixedly connected to the left side of the first flange 9. A filter 8 is fixedly connected to the left side of the oil pipe. Another oil pipe is fixedly connected to the left side of the filter 8. A second flange is fixedly connected to the left side of the other oil pipe. A cavity 10 is opened inside the first flange 9. A support rod 11 is fixedly connected to the bottom inner wall of the cavity 10. A first spring 12 is sleeved on the outer wall of the support rod 11, which can effectively distribute the load, thereby reducing pressure and friction and prolonging the service life of related components. A telescopic buckle 13 is slidably connected to the top of the support rod 11. A square rod 15 is slidably connected to the top of the telescopic buckle 13. A second spring 14 is sleeved on the outside of the square rod 15. A limit block 16 is fixedly connected to the bottom end of the square rod 15, which can help ensure that the mechanical system stops at a specific position, thereby preventing excessive movement or accidental movement and improving the safety of the system. A sealing component is arranged inside the first flange 9.

[0027] Referring to Figures 4 - 6, The sealing assembly includes a circular groove 17, and an O-ring 18 is clamped inside the circular groove 17, which can effectively prevent fluid or gas leakage, ensure the sealing performance of the system, prevent the leakage of the medium or the entry of external pollutants. Inside the outer side of the first flange 9, a support clamp 19 is fixedly connected. Inside the cavity 10, a square block 20 is provided. The clamping surface of the support clamp 19 clamps an I-shaped sealing ring 21. On the right side of the pipe 7, there is a necked flange 23, which can effectively transmit the torque between shafts, enabling the mechanical system to operate normally. Inside the necked flange 23, a filter screen 22 is fixedly connected.

[0028] Refer to Figures 3 - 5 , The outside of the driving gear 3 meshes with the outside of the driven gear 5.

The right side is fixedly connected to the outer wall of the pipe 7.

[0030] Working principle: Start the motor 1 to drive the drive shaft 2 to rotate. The rotation drives the driving gear 3, and the driving gear 3 drives the driven gear 5 to rotate, thereby generating suction to suck the oil into the pipe 7. It flows from the pipe 7 into the necked flange 23, and is roughly filtered through the filter screen 22, and then is transported to the filter 8 through the pipe 7. When the filter 8 is blocked or fails, turn off the power supply, press down the square rod 15. The square rod 15 moves downward, the limit block 16 presses down the second spring 14 downward, the bottom end of the square rod 15 presses on the telescopic buckle 13, and the telescopic buckle 13 presses down the first spring 12 to make the telescopic buckle 13 contract into the cavity 10, then the first flange 9 can be removed.

[0031] Put the O-ring 18 into the circular groove 17, and then put the concave surface of one side of the I-shaped sealing ring 21 into the clamping surface of the support clamp 19. Close the two first flanges 9 through the telescopic buckle 13 to achieve sealing.
