滚珠式行星减速器实际上就是用滚珠代替齿轮,用摩擦传动代替齿轮啮合的一种行星减速器。下面介绍一种简单的滚珠式行星减速器。图1为减速器结构图。全机由心套1、保持器2、输出皮带轮3、端盖4以及三个标准轴承组成,其中轴承G_1、G_2用作行星减速,G_3作普通轴承用。图2为传动原理图。太阳轮1由心轴配装轴承G_1、G_2的内圈组成。行星轮2由轴承G_1、G_2滚珠组成,并由铜套保持器联系起来。 Ball-type planetary reducer is actually a ball instead of gear, with friction instead of gear meshing planetary reducer. Here’s a simple ball-type planetary reducer. Figure 1 for the reducer structure. The whole machine consists of a heart sleeve 1, a retainer 2, an output pulley 3, an end cover 4 and three standard bearings, wherein the bearings G_1 and G_2 are used for planetary deceleration and G_3 for ordinary bearings. Figure 2 is the transmission principle diagram. The sun gear 1 is composed of the inner ring of the bearing G_1 and G_2 assembled with the spindle. Planet 2 consists of bearings G_1, G_2 balls, and by the copper sleeve holder connected.
