AI Technical Summary
The existing reducer's lubricating oil circulation circuit is easily affected by the rotation direction of the drive shaft, resulting in unstable operation and difficulty in achieving a robust and durable lubrication effect.
The design of the combination of shaft-end pump and valve unit makes the direction of lubricating oil flow independent of the rotation direction of the drive shaft. The design of the orifice in the gear pump area and the inner cavity area of the valve unit ensures stable delivery of lubricating oil, and the use of check valve and spring element realizes stable lubricating oil circulation.
It achieves stable operation of the lubricating oil circulation loop, independent of the rotation direction of the drive shaft, ensuring effective lubrication of all lubrication points in the reducer, simplifying the structure and reducing dependence on the drive device.
