本発明は互に相対回転する物体の対向球面間に
介在させて用いるスラストワツシヤに関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thrust washer that is interposed between opposing spherical surfaces of objects that rotate relative to each other.

在させる。 An example of this type of thrust washer used in a differential gear is conventionally constructed as shown in FIG. In this figure, 1 is a differential case, 2 is a pinion gear, 3 is a pinion shaft that rotatably supports the pinion gear 2 within the differential case 1, and 4 is a thrust washer.
During operation of the differential gear, the Tef case 1 and the pinion gear 2 rotate relative to each other around the pinion shaft 3, and during this relative rotation, the spherical surface 2a of the pinion gear 2 comes into contact with the spherical surface 1a of the differential case 1 to prevent wear of the spherical surface 1a. To prevent this, a thrust washer 4 is interposed between these opposing spherical surfaces 1a and 2a.

役目を十分果たし得ないのが実情であつた。 However, the conventional thrust washer 4 has a spherical surface 1
The thrust washer 4
The pinion gear 2 rotates the thrust washer 4 because both surfaces are in full contact with the corresponding differential case spherical surface 1a and the pinion gear spherical surface 2a, and the contact areas are almost the same on both sides. Therefore, the conventional thrust washer 4 generates relative rotation with the differential case 1, causing wear on the spherical surface 1a, and cannot sufficiently fulfill its original role of eliminating wear on the differential case 1.
本発明はかかる問題を解決するためなしたもの
で、スラストワツシヤを球面状に湾曲させるも、
その曲率半径をスラストワツシヤが介在されるべ

ツシヤを提供しようとするものである。 The present invention was made to solve this problem, and although the thrust washer is curved into a spherical shape,
The object of the present invention is to provide a thrust washer whose radius of curvature is larger than the radius of curvature of the opposing spherical surface on which the thrust washer is interposed.
以下、図示の実施例により本発明を詳細に説明
する。 Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.
第２図は、第１図におけると同様デイフアレン

本発明においては、スラストワツシヤ５を球面状
に湾曲させるも、その曲率半径を対向球面１ａ，
２ａの曲率半径より大きくする。そして、かかる
スラストワツシヤ５は従来と同様デフケース１及
びピニオンギヤ２間、即ち夫々の球面１ａ，２ａ
間に介在させて実用に供する。 FIG. 2 shows a thrust washer of the present invention used in a differential gear similar to that shown in FIG. 1, and this thrust washer is designated by 5 in FIG.
In the present invention, although the thrust washer 5 is curved into a spherical shape, the radius of curvature is set to the opposite spherical surface 1a,
The radius of curvature is larger than that of 2a. The thrust washer 5 is arranged between the differential case 1 and the pinion gear 2, that is, the spherical surfaces 1a and 2a, as in the conventional case.
It is put into practical use by interposing it in between.
本発明スラストワツシヤ５は曲率半径を上述の
如くに設定したことで、当該実用中内球面内周部
５ａがピニオンギヤ２の球面２ａと接し、又外球
面外周部５ｂがデフケース１の球面１ａに接する
こととなり、その他の部分では球面１ａ，２ａの
いずれとも接触せず、これら球面との間に隙間
６，７を生ずる。 In the thrust washer 5 of the present invention, the radius of curvature is set as described above, so that the inner spherical inner peripheral part 5a in practical use contacts the spherical surface 2a of the pinion gear 2, and the outer spherical outer peripheral part 5b contacts the spherical surface 1a of the differential case 1. In other parts, it does not come into contact with either of the spherical surfaces 1a and 2a, creating gaps 6 and 7 between these spherical surfaces.
ところで、デフケース１及びピニオンギヤ２の
相対回転中心、即ちピニオンシヤフト３の軸心か

ニオンギヤ２につれ廻りされず、デフケース１に
より回転しないよう拘束される。 Incidentally, since the relative rotation center of the differential case 1 and the pinion gear 2, that is, the distance from the axis of the pinion shaft 3 to the contact portions 5a and 5b is longer in the latter, the movement of the thrust washer 5 is mainly restrained by the differential case 1. . Therefore, the pinion gear 2 is connected to the differential case 1 around the pinion shaft 3.
While the thrust washer 5 rotates relative to the pinion gear 2, the thrust washer 5 is not rotated by the pinion gear 2 and is restrained from rotating by the differential case 1.

明通りスラストワツシヤ５が回転するのを防止

ツシヤ本来の役目が達成される。 Thus, although the thrust washer 5 of the present invention is curved into a spherical surface as described above, the radius of curvature is set to the opposing spherical surface 1a, which the thrust washer 5 should interpose,
Since the radius of curvature is larger than that of 2a, it prevents the thrust washer 5 from rotating as explained above, and this prevents the thrust washer 5 from rotating when the corresponding object (in the illustrated example, the differential case 1)
This can prevent the thrust washer from wearing out, and the original role of the thrust washer can be achieved.
又、本発明スラストワツシヤ５は上述した構成
上の特徴から、これを介在させるべき対向球面１
ａ，２ａとの間に夫々隙間６，７を生じさせ、こ
れら隙間に潤滑油が抱持させ得ることから、潤滑

ことができる。 Furthermore, due to the above-mentioned structural features, the thrust washer 5 of the present invention has an opposing spherical surface 1 on which it should be interposed.
Since gaps 6 and 7 are formed between the parts a and 2a, and the lubricating oil can be held in these gaps, lubrication is performed well and wear can be reduced in this respect as well.
