Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of hydraulic power unit of speed reducer, including reducer shell 1, opened up in reducer shell 1
Be separately installed under on perforative Kong Weicong deep groove ball bearing A2, deep groove ball bearing B3, circlip for hole 4, bearing holder (housing, cover) 5,
Terminal pad 6 and sealing ring 7 are fixed with flat key 51, deep groove ball bearing C52 and freewheel clutch 53, axis on the inner peripheral surface of bearing holder (housing, cover) 5
It is cased with the deep groove ball bearing D91 to connect with reducer shell 1 on 9 outer wall of secondary pullover of 5 peripheral surface of bearing sleeve welding coaxial line, it is multiple
Bearing promotes the protection of transmission shaft 31, and deep groove ball bearing D91 facilitates the rotation in reducer shell 1 of secondary pullover 9, rises simultaneously
To the effect of support, transmission shaft 31 is connected in deep groove ball bearing B3, deep groove ball bearing B3 is that one end of transmission shaft 31 is revolved
Turn to provide support force, the other end of transmission shaft 31 runs through circlip for hole 4, flat key 51, deep groove ball bearing C52 and overdrive clutch
