Title (EN) WORM GEAR SWIVEL BEARING
(FR) PALIER D'ARTICULATION À VIS SANS FIN
(JA) ウォームギヤ旋回ベアリング
Abstract:
(EN) This worm gear swivel bearing (1) is provided with an outer race (20) comprising a worm wheel gear (22) provided on the outer periphery, and with a worm (40) which meshes with the worm wheel gear (22). The worm wheel gear (22) is formed straddling between the outer peripheral surface (20b) of the outer race (20) and any one end surface (20d) of the outer race (20) in the axial direction. The rotation center (O2) of the worm (40) is displaced in the axial direction towards the end surface (20d) from the center of a rolling element (30), and the line (L) which connects said rotation center (O2) and the point of contact (X1) of the worm wheel gear (22) is inclined in the radial direction.
(FR) La présente invention concerne un palier d'articulation à vis sans fin (1) doté d'un chemin de roulement extérieur (20) comprenant un engrenage à roue-vis (22) placé sur la périphérie externe, et d'une vis sans fin (40) qui entre en prise avec l'engrenage à roue-vis (22). L'engrenage à roue-vis (22) est formé par chevauchement entre la surface périphérique externe (20b) du chemin de roulement extérieur (20) et toute surface d'extrémité (20d) du chemin de roulement extérieur (20) dans la direction axiale. Le centre de rotation (O2) de la vis sans fin (40) est déplacé dans la direction axiale vers la surface d'extrémité (20d) depuis le centre d'un élément roulant (30), et la ligne (L) qui relie ledit centre de rotation (O2) et le point de contact (X1) de l'engrenage à roue-vis (22) est inclinée dans la direction radiale.
(JA) このウォームギヤ旋回ベアリング(1)は、ウォームホイールギヤ(22)を外周に備える外輪(20)と、ウォームホイールギヤ(22)と噛み合うウォーム(40)と、を備える。ウォームホイールギヤ(22)は、外輪(20)の外周面(20b)と、アキシャル方向における外輪(20)のいずれか一方の端面(20d)と、に跨って形成されている。ウォーム(40)は、その回転中心(O2)がアキシャル方向において転動体(30)の中心よりも端面(20d)側に変位しており、且つ、その回転中心(O2)とウォームホイールギヤ(22)との接触点(X1)を結ぶ直線(L)がラジアル方向に対して傾いている。
