Component；The left end set female connector fork of the roller end joint assembly；
The retainer component includes,
The bearing being sleeved on right ring-shaped step, the right end of bearing are equipped with retaining ring, and the left end of bearing is set with left end cap, left end
The right end of lid and left ring-shaped step clearance fit, bearing is socketed right end cap, right end cap and right ring-shaped step clearance fit, the left side
Sealing ring, the outer ring of the bearing are respectively equipped between the interior edge of end cap and left step, between the interior edge of right end cap and right step
It is socketed support ring, the outer of right end cap is circumferentially uniformly provided with several through-holes, and the outer of support ring is circumferentially uniformly provided with several
Through-hole, the outer of left end cap are circumferentially uniformly provided with several threaded holes, on the through-hole, support ring on screw bolt passes right end cap
Through-hole rear thread connect left end cap.
Several pump nozzles are additionally provided on the circumferential surface of the support ring, which is connected to oil filler point, which extends to
The inside of bearing.
It is described to be connected as welding.
The present invention overcomes traditional directed thinking, and retainer component is placed in the right end of roller end joint assembly, avoids biography
Defect existing for system shaft coupling, improves service life, reduces use cost, be easily installed and repair, and improves production effect
Rate.
Detailed description of the invention
Fig. 1 is schematic diagram of main cross-sectional structure of the present invention.
Fig. 2 is the local A enlarged diagram of Fig. 1.
Fig. 3 is former shaft coupling schematic diagram of main cross-sectional structure.
Specific embodiment
It is more apparent to enable those skilled in the art to have the present invention, a letter is made to former shaft coupling first
Single introduction, as shown in Figure 3 comprising roller end joint assembly 11, is sleeved on spline at the splined shaft 13 for connecting roller end joint assembly
