Abstract

PROBLEM TO BE SOLVED: To provide higher dimensional accuracy in a uniform universal coupling constituted by interposing a cage retaining a plurality of balls between an inner member and an outer member by working a ball groove on at least either of the inner member and the outer member through grinding finish after heat treatment. SOLUTION: In an outer member 1 connected to a stem 7 as a driving shaft, a ball groove 5 is formed nearly along the inner diameter spherical surface on the nearly half part on the root part side. Meanwhile, an inner member 2 connected to a driven shaft (two-dot chain line) is formed with a ball groove 6 nearly along the outer diameter spherical surface on the nearly half part on the root part side on the outer circumference. Balls 3,... are arranged between these ball grooves 5, 6, and the balls 3,... are retained with a cage 4. When such uniform universal coupling is manufactured, it is forged from raw material, and after heat treatment such as quenching, the outer member 1 and the inner member 2 are formed, thereafter the ball groove 5 is worked by grinding finish. Meanwhile the inner member 2 is left in the state of forging.

On the inner periphery of the outer member 1, a radially extending groove having a straight groove bottom substantially in the axial direction in a substantially half portion on the distal end side and a groove substantially along the inner diameter spherical surface in a substantially half portion on the root side. A groove 5 having a bottom is formed. Inside the outer member 1, a partially spherical inner member 2 connected to a driven shaft (two-dot chain line) is arranged. The outer periphery of the inner member 2 has a straight groove bottom substantially along the axial direction at a substantially half portion on the distal end side corresponding to the groove 5 of the outer member 1, and has an outer spherical surface at a substantially half portion on the root side. A groove 6 having a groove bottom substantially along the line is formed.

Although the ball 3 is held by the cage 4, the inner peripheral surface 4 a of the cage 4 comes into surface contact with the convex spherical surface 2 a of the inner member 2, and the outer peripheral surface 4 b of the cage 4 contacts the concave spherical surface 1 a of the outer member 1.

±０．０３ｍｍ以下となる。When manufacturing the constant velocity universal joint according to the present embodiment, the outer member 1 and the inner member 1 are first formed by forging from a raw material, and after heat treatment such as quenching. Here, the ball groove 5 of the outer member 1 is further subjected to grinding finish processing. In this case, the dimensional accuracy is such that the ball groove radius is 51 to 55%, the PCD is ± 0.02 mm or less with respect to the design value, and the offset amount is ± 0.03 mm or less with respect to the design value.

足りる。On the other hand, the inner member 2 is forged so as not to significantly increase the manufacturing cost, and the dimensions of the ball grooves 6 are measured to thereby divide them into about three groups according to the dimensions. The dimensions of the ball grooves 5 of the outer member 1 can be precisely adjusted in advance by grinding to the dimensions of the ball grooves 6 in each group of the inner member 2. That is, the manufactured inner member is always used regardless of the groove size, and therefore, the number of parts to be stored is small.

It is necessary to measure the dimensions of the ball groove 5 and select and combine the inner member 2 having the ball groove 6 of the dimension corresponding to the dimension. Therefore, it is necessary to always prepare the inner member 2 divided into about four groups according to the groove size of the outer member 1. However, the groove dimensions of the outer member do not always vary uniformly, and there may be a group of inner members that are not used for a long time. That is, according to the present embodiment, the number of parts to be stored is reduced by one in comparison with the prior art.

きる。The stress of the stem of the outer member increases during operation, and therefore, it can be said that the strength of the stem should be considered most. Therefore, high carbon steel is originally used as the material of the outer member, and it is desired to perform induction hardening on the material. However, when high carbon steel is used, plastic workability deteriorates and deformation after heat treatment also increases. Therefore, in the prior art, a carburizing material is generally used as a material of the outer member formed by forging. However, if the ball groove is formed by grinding as in the present embodiment, high carbon steel, which is advantageous in strength, can be used as the material of the outer member. Properties can be further improved.
