    • A combined roller and retainer assembly for a planetary gear mechanism, including a planetary gear and a support shaft for supporting the planetary gear, includes a roller retainer (1) and a plurality of rollers (2) and is adapted to be interposed between the planetary gear and the support shaft for supporting the planetary gear and the support shaft through the rollers (2). The roller retainer (1) includes a pair of annular portions (103, 104) spaced in an axial direction from each other and a plurality of pillars (105) extending between respective outer peripheral edges of the annular portions (103, 104) and spaced in a direction circumferentially of the annular portions (103, 104). The rollers (2) are accommodated within respective pockets (106) each defined between the neighboring pillars (105). One or both of the annular portions (103, 104) are provided with roller retaining pawls (107) of a bent shape in respective portions of inner peripheral portions of the annular portions (103, 104) at a location aligned with the neighboring rollers (2) for constraining the rollers (2) from separating in a direction radially inwardly of the roller retainer (1). The roller retaining pawls (107) are annealed or treated not to be carburized to have a hardness about equal to or lower than the hardness of the roller retainer (1) and equal to or lower than Hv 400.
    • 一种用于行星齿轮机构的组合辊和保持器组件,包括行星齿轮和用于支撑行星齿轮的支撑轴,包括滚子保持器(1)和多个滚子(2),并且适于夹在行星齿轮 齿轮和用于通过辊(2)支撑行星齿轮和支撑轴的支撑轴。 辊保持器(1)包括在轴向彼此间隔开的一对环形部分(103,104)和在环形部分(103,104)的相应的外周边缘之间延伸并间隔开的多个柱(105) 在环形部分(103,104)周向的方向上。 辊(2)容纳在相邻的柱(105)之间各自限定的凹穴(106)中。 环形部分(103,104)中的一个或两个在与相邻辊对齐的位置处设置有环形部分(103,104)的内周部分的相应部分中的弯曲形状的辊保持爪(107) 2)用于约束辊(2)在辊保持器(1)的径向向内的方向上分离。 辊保持爪(107)进行退火处理,不进行渗碳处理,其硬度大约等于或低于辊保持器(1)的硬度,并且等于或低于Hv400。
