[0006] Furthermore, a sealing groove is provided near the edge of the base, a sealing ring is provided in the sealing groove, and the edge of the end cover is in close contact with the edge of the base.

[0007] Furthermore, an oil outlet is provided on the side wall of the fastening bolt, and the oil passage is connected with the interior of the oil mark housing through the oil outlet.

[0008] Furthermore, the base and the end cover are respectively provided with a first mounting hole and a second mounting hole allowing fastening bolts to pass through, the first mounting hole is provided with an inwardly protruding reinforcing rib, and the side wall of the reinforcing rib is provided with an oil outlet groove at a position corresponding to the oil outlet.

[0009] Furthermore, the first mounting hole is provided with a first sealing rubber pad at the mounting position of the fastening bolt.
