ガタが発生するようなことがある。
In conventional universal joints of this type (for example, Japanese Patent Publication No. 50-53613), the bearing case of the bearing that supports the trunnion of the cross shaft in the bearing hole of the yoke rotates in the circumferential direction within the bearing hole. However, seizure or play may occur between the yoke and the bearing case.
このような焼きつきは、ユニバーサルジヨイン
トの性能に悪影響を及ぼし、またガタにより止め
輪が損傷するおそれがある。 Such seizure may adversely affect the performance of the universal joint, and the retaining ring may be damaged due to backlash.
しかもベアリングの外輪は熱処理された高硬度
の材質からなるので、直接ピンで廻り止めをする
と外輪との間に〓間が生じるとともに外輪が欠け
易い。 Moreover, since the outer ring of the bearing is made of a heat-treated material with high hardness, if the rotation is stopped directly with a pin, a gap will be created between the outer ring and the outer ring, and the outer ring will easily break.
また、ボルトで直接ヨークに固定する場合に
は、ベアリングに力が加らると外輪が歪む。しか
も、その歪みはヨークに生じる歪みと異なるた
め、高硬度に形成されたベアリング外輪が割損し
易い。 Additionally, if the bearing is directly fixed to the yoke with bolts, the outer ring will become distorted if force is applied to the bearing. Moreover, since the distortion is different from the distortion occurring in the yoke, the outer ring of the bearing, which is formed with high hardness, is likely to break.

浸入を防げない。 Furthermore, for relatively large universal joints, it is difficult to assemble if an interference is provided between the outer ring and the yoke hole, so it is necessary to use a small interference or a "loose fit". has been done. Therefore, the outer periphery cannot be sealed and water cannot be prevented from entering.

のである。 The purpose of this invention is to prevent the above-mentioned conventional drawbacks, that is, to securely fix the bearing case in the bearing hole of the yoke in a non-rotatable manner and without any looseness. The purpose of this is to prevent rust between the bearing hole and the bearing hole.

As described above, the present invention provides a universal joint in which a bearing case fitted in a bearing hole of a yoke is fixed by a retaining ring fitted in a circumferential groove provided on the inner periphery of the bearing hole. is fixed to the outer bottom surface of the bearing case with the retaining ring in between, is fitted into the bearing hole immediately, and is provided with a rotation preventing means that prevents the cover member from rotating relative to the bearing hole. , the bearing case, especially its rolling element raceway, is completely and immovably fixed in the bearing hole without any processing, and the bearing case remains stable even under long and harsh use of the universal joint. Completely prevents seizure between the yoke and the yoke. Therefore, there is no need to strictly specify the fit accuracy between the bearing case and the bearing hole.
It is possible to facilitate the machining, or the work steps such as bearing replacement and assembly, and to suppress the occurrence of backlash.
