Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the present invention provides a kind of technical solution: a kind of wet multi-disc shaft coupling, including it is outer housing 1, defeated
Enter end housing 2 and output end housing 3, the input end housing 2 and output end housing 3 are solid with outer housing 1 respectively by bolt 7
Fixed connection, 3 side of output end housing are connected with piston 6 by spring 10, set between the piston 6 and input end housing 2
There is brake disc 5, pushes piston 6 and brake disc 5 to carry out flexible connected using the pressure of spring 10；1 side of outer housing is close
6 position of piston is equipped with hydraulic oil port 14, and external hydraulic system is by hydraulic oil port 14 for oil pressure；6 side of piston passes through
The symmetrically arranged guide post 12 of six groups be fixedly connected is plugged on outer housing 1, and corresponding offer matches on the outer housing 1
Jack 13, the depth of the jack 13 is greater than the length of guide post 12, and the matching relationship of guide post 12 and jack 13 is clearance fit.
Specifically, the input end housing 2 and output end housing 3 are respectively further from 1 side of outer housing and are welded with flange 4,
Circumferential direction offers threaded hole 401 on the flange 4；By 4 structure of flange facilitate respectively with input terminal and output end abutting joint.
Specifically, being equipped with the first sealing ring 8 far from 4 side of flange in the input end housing 2 and output end housing 3；
The first sealing ring 8, which is arranged, can be improved input end housing 2 and exports the leakproofness of 3 inside docking location of end housing.
