Improved end cover for universal joint pin type universal coupler

Abstract

The invention discloses an improved end cover for a universal joint pin type universal coupler. The end cover body takes the shape of a round disc; arced flanges are symmetrically arranged on the outer side surface of the end cover body; a flat column is arranged on one side of the end cover body; the diameter of the column is the same as that of the round-disc-shaped end cover body; an inclined surface is arranged from the top surface to each of the two sides of the column; the two inclined surfaces are arranged symmetrically. The improved end cover is simple in structure, reasonable in design, low in manufacturing cost, and capable of eliminating a gap between the end cover body and a flange fork, internal space of the end cover body is effectively utilized, and the overall rigidity of the end cover body is improved.

Description

technical field [0001] The invention belongs to the technical field of universal joints, in particular to an improved end cover for a cross-shaft type universal joint. Background technique [0002] At present, the cross-shaft universal coupling has been widely used in mining, metallurgy, chemical industry, shipbuilding and other industries. It transmits motion and torque between the prime mover and the working machine. It must bear large loads and frequent shock. The cross shaft journal of the cross shaft universal coupling is installed in the bearing hole of the flange yoke, and the outer end of the cross shaft bearing seat is fixed with an end cover through bolt connection, and the end cover bears a huge axial impact load. The end caps of traditional cross shaft universal couplings mostly adopt disc-shaped structures, such as figure 1 As shown, the thickness of the edge of the end cover is reduced along the circumferential direction, and about 1 / 2 of the reduced space is...

AI Technical Summary

Problems solved by technology

The end caps of traditional cross shaft universal couplings mostly adopt disc-shaped structures, such as figure 1 As shown, the thickness of the edge of the end cover is reduced along the circumferential direction, and about 1 / 2 of the reduced space is not fully utilized; and the outer edge of the end cover is evenly distributed along the circumferential direction. The screws in each threaded hole are firmly connected, which requires that the torque wrench apply the same torque to each screw during assembly to ensure uniform tightening. Therefore, the assembly requirements are high and it is not easy to operate, and the end cover has been used for a long time. Damaged screws are not easy to remove
