Abstract:
(EN) This bearing structure for a motor enables to save assembling man-hours. A first bearing structure (91) as an example of a bearing structure for a motor according to the present invention is provided with a first bearing (91a), a second bearing (91b), a first holding member (92a), a second holding member (92b), and an elastic body (93). The bearings (91a, 91b) are arranged in the axial direction of a first shaft (22c). The bearing holding members (92a, 92b) respectively hold the bearings (91a, 91b). The elastic body (93) is gripped between the axially adjacent bearings (91a, 91b) and is surrounded by the second holding member (92b). A first length (L1) which is the radial distance between the outermost part (93b) of the elastic body (93) and the second holding member (92b) is less than a second length (L2) which is the radial distance between the outermost part (93b) of the elastic body (93) and the first shaft (22c). The first length (L1) is less than a third length (L3), which is the radial distance between the innermost part (93a) of the elastic body (93) and the first shaft (22c).
(FR) La présente invention concerne une structure de palier destinée à un moteur et permettant d'économiser des heures d'assemblage. Une première structure de palier (91) donnée comme exemple d'une structure de palier pour un moteur selon la présente invention est pourvue d'un premier palier (91a), d'un second palier (91b), d'un premier élément de maintien (92a), d'un second élément de maintien (92b), et d'un corps élastique (93). Les paliers (91a, 91b) sont disposés dans la direction axiale d'un premier arbre (22c). Les éléments de maintien de palier (92a, 92b) maintiennent respectivement les paliers (91a, 91b). Le corps élastique (93) est saisi entre les paliers axialement adjacents (91a, 91b) et est entouré par le second élément de maintien (92b). Une première longueur (L1) qui est la distance radiale entre la partie la plus à l'extérieur (93b) du corps élastique (93) et le second élément de maintien (92b) est inférieure à une deuxième longueur (L2) qui est la distance radiale entre la partie la plus à l'extérieur (93b) du corps élastique (93) et le premier arbre (22c). La première longueur (L1) est inférieure à une troisième longueur (L3), qui est la distance radiale entre la partie la plus à l'intérieur (93a) du corps élastique (93) et le premier arbre (22c).
(JA) 本発明に係るモータの軸受構造は、組み立て工数を抑えることができる。本発明に係るモータの軸受構造である第1軸受構造(91)は、第1軸受(91a)と第2軸受(91b)と第1保持部材(92a)と第2保持部材(92b)と弾性体(93)とを備える。軸受(91a,91b)は、第1シャフト(22c)の軸方向に沿って配置される。軸受保持部材(92a,92b)は、それぞれ、軸受(91a,91b)を保持する。弾性体(93)は、軸方向に隣り合う軸受(91a,91b)の間に挟み込まれ、第2保持部材(92b)に囲まれている。弾性体(93)の最外部(93b)と第2保持部材(92b)との間の径方向の距離である第1長さ(L1)は、弾性体(93)の最外部(93b)と第1シャフト(22c)との間の径方向の距離である第2長さ(L2)より短い。第1長さ(L1)は、弾性体(93)の最内部(93a)と第1シャフト(22c)との間の径方向の距離である第3長さ(L3)より短い。
