During the use of the gearbox, lubricating fluid needs to be filled into it. However, since the filling hole position of the gearbox is constant, it is necessary to guide the lubricating oil to the key lubrication points inside the gearbox to ensure that components such as gears and bearings are fully lubricated.

[0003] Chinese Patent CN117514584A discloses an anti-cavitation oil separation plate. The oil separation plate is provided with an outer sealing belt and an inner sealing belt. The oil separation plate is provided with an oil suction chamber and an oil discharge chamber. Both the oil suction chamber and the oil discharge chamber are located between the outer sealing belt and the inner sealing belt. An upper dead zone and a lower dead zone are formed between the oil suction chamber and the oil discharge chamber. The oil separation plate is provided with a first oil passage and a second oil passage. One end of the first oil passage is located on the wall of the oil suction chamber, and the other end of the first oil passage is located in the upper dead zone. One end of the second oil passage is located on the wall of the oil discharge chamber, and the other end of the second oil passage is located in the upper dead zone, which has the advantage of being able to prevent cavitation.

[0004] However, although this technical solution is provided with an oil suction chamber and an oil discharge chamber, it cannot perform the function of filling lubricating oil from the outside and guiding it, resulting in the existing oil separation plate being unable to meet the requirements of gearbox lubricating oil filling, and there are deviations in the filling of lubricating oil, leading to poor lubrication effect of the gear body.
