Description

【考案の詳細な説明】 （技術分野） 本考案は、自在継手における十字軸の軸受の押
え装置に関するものである。[Detailed Description of the Invention] (Technical Field) The present invention relates to a holding device for a bearing of a cross shaft in a universal joint.

頂部を押えるスナツプリングである。(Prior Art) Conventionally, there is a type of universal joint in which a cross shaft bearing inserted into a bearing holding hole of a yoke is held down by a snap spring. Figure 1 shows this type of universal joint, where 1 is a yoke, 2 is a cross shaft, 3 is a bearing inserted into the bearing holding hole of yoke 1, and 4 is a snap ring that presses the top of bearing 3. .

が破損するという欠点があつた。 By the way, the fit between the bearing and the holding hole is generally a loose fit or a loose fit, so it is basically slidable. It slides due to the surface pressure of the end. This is because even if a shimeshiro is provided, the rigidity of the yoke is small, resulting in uneven contact, and the result will be the same. As described above, as a result of the looseness between the bearing and the holding hole, there was a drawback that the tip of the yoke was damaged.

あつた。 On the other hand, there is a so-called presser plate type universal joint that suppresses the sliding of the bearing. This is a method in which a concave portion or a convex portion is provided at the top of the bearing, and a presser plate having a protrusion or hole that engages with the concave portion or convex portion is used to hold down the top portion of the bearing and fix it to a yoke. However, this configuration was disadvantageous in terms of cost.

する。(Purpose of the invention) The present invention aims to improve the above-mentioned drawbacks of the conventional example, by shifting the center of the bearing and the center of the snap spring, and by making the convex part provided at one end of the snap spring engage the groove provided at the top of the bearing. To provide a bearing holding device for a universal joint, which has a simple structure and is low in cost, which suppresses the sliding of a bearing. Hereinafter, embodiments will be described in detail based on the drawings.

11 indicates a part of the yoke. 12 is a bearing holding hole, the center of which is p1 . Reference numeral 13 is a stop hole for the snap spring, and its center p2 is offset from the center p1 of the bearing holding hole. 14 is a bearing inserted into the holding hole 12, and a groove 14a is provided at the top of the bearing. Reference numeral 15 denotes a snap spring, and one end thereof has a convex portion 15a that engages with a groove 14a provided at the top of the bearing.

If the bearing 14 is inserted into the bearing 14 and the snap ring 15 is fitted into the stopper hole 13 of the yoke 11 from above and held down, the protrusion 15a of the snap ring 15 will engage with the groove 14a on the top of the bearing, and , since the center p 1 of the bearing and the center p 2 of the snap spring are misaligned, the bearing 14 cannot rotate.

Furthermore, since the structure is simple, it can be realized at low cost.
