Abstract

Official abstract text for this publication.

A universal joint includes a pair of yokes and a joint cross. The pair of yokes have mutually identical shapes. Each of the yokes has a proximal portion and a pair of arm portions at which the joint cross is mounted. The proximal portion has an insertion hole for mounting a shaft, a slit formed along the insertion hole and a bolt insertion hole for fastening the slit. A positional relationship between the proximal portion and the pair of arm portions is set such that a line segment that connects the pair of arm portions to each other and an insertion direction in which a bolt is inserted in the bolt insertion hole intersect with each other at 45°. The bolt insertion holes of the pair of yokes coupled by the joint cross face the same side.

First claim

Opening claim text (preview).

The invention claimed is: 1. A yoke integrally comprising: a proximal portion; a pair of arm portions that extend from the proximal portion, the pair of arm portions being used for mounting a joint cross; a rib portion that projects from the proximal portion toward bases of the pair of arm portions; and a pair of flanges, wherein a base adjacent to the rib portion is thick so as to rise toward the counterpart arm portion, the proximal portion has an insertion hole for mounting a shaft, a slit formed along the insertion hole and a bolt insertion hole for fastening the slit, a positional relationship between the proximal portion and the pair of arm portions is set such that a line segment that connects the pair of arm portions to each other and an insertion direction in which a bolt is inserted in the bolt insertion hole intersect with each other at 45°. 2. A universal joint comprising: a pair of yokes; and a joint cross that couples the pair of yokes such that the pair of yokes are relatively displaceable, wherein the pair of yokes have mutually identical shapes, each of the yokes integrally has a proximal portion, a pair of arm portions, a rib portion and a pair of flanges, each of the arm portions extends from the proximal portion, the joint cross is mounted to the arm portions, the rib portion projects from the proximal portion toward bases of the pair of arm portions, a base adjacent to the rib portion is thick so as to rise toward the counterpart arm portion, the proximal portion has an insertion hole for mounting a shaft, a slit formed along the insertion hole and a bolt insertion hole for fastening the slit, a positional relationship between the proximal portion and the pair of arm portions is set such that a line segment that connects the pair of arm portions to each other and an insertion direction in which a bolt is inserted in the bolt insertion hole intersect with each other at 45°, and in a state where the pair of yokes are coupled by the joint cross, the bolt insertion holes of the pair of yokes face the same side.
