Embodiment Construction

[0013] From figure 1 It can be seen that the fork head of the present invention has a base 1 for fixing the shaft, and a pair of parallel arms 2 extending from the base.

[0014] From figure 2 It can be seen that the top 3 of each arm 2 of the fork is a conical surface with an angle α; the angle of the cone is twice the limit angle of the fork. For example: when the cone angle α = 20 degrees, the limit angle of the fork is 10 degrees, that is to say figure 2 The yoke shown in the yoke will not exceed the turning diameter of the yoke itself within a range of 10 degrees of inclination.

[0015] From image 3 It can be seen that the cut-off size of the bottom 4 of the internal cavity of the fork is determined by the relative size of the top 3 of the arm plus a certain margin. In this way, while meeting the requirements of the inclination angle, the cutting amount of the top is minimized, so that the strength of the fork is maximized. From Figure 6 It can be seen that the...

Abstract

The invention relates to a forkhead of a universal coupling, in particular to an integral forkhead of a SWC type cross-shaped universal coupling. The forkhead comprises a base part (1) used for fixinga shaft and a pair of parallel arms (2) extending from the base part. The top (3) of each arm (2) is a conical surface, the shape of the bottom (4) of the inner cavity of the forkhead is matched withthat of the top (3) of the arm. The cutting size of the bottom (4) of the inner cavity of the forkhead is determined by summing the relative size of the top (3) of the arm and a certain allowance. With the conical surface of the top of the pair of arms, the forkhead can meet the requirement that any part of the forkhead can not exceed the turning radius of the forkhead when the forkhead works atan inclination angle, so that the phenomenon of interference of the forkhead to a matched forkhead can not occur. Because the cutting size of the bottom (4) of the inner cavity of the forkhead is determined by summing the relative size of the top (3) of the arm and a certain allowance, the bottom has minimum cutting amount, i.e. highest strength when meeting the inclination angle and the forkheadof the universal coupling has higher strength.

Description

technical field [0001] The invention relates to a yoke for a universal joint, in particular to an integral yoke of a SWC type cross universal joint. Background technique [0002] As an important part of the cross joint of the SWC cross universal coupling, the integral fork must not only meet the requirements for assembly with the cross shaft, but also meet the requirements for its own strength. The top of each arm of the existing yoke is a cylindrical surface, the cutting amount of the bottom of the inner cavity of the yoke is large, the strength of the yoke is reduced, and the yoke is prone to breakage. Therefore, how to make the integral SWC type yoke obtain the maximum strength under the premise of satisfying the structural dimensions such as inclination angle assembly is a difficult point in the design of the yoke. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-strength integral yoke for the SWC cros...
