Abstract: An epicyclic drive (A) has its planet gears (6) integrated into separately built planet assemblies (B). Each planet assembly (B), in addition to its planet gear (6), includes a pin (34) which extends through the planet gear (6) and an antifriction bearing (36) located between the gear (6) and the pin (34). The outer raceways (72, 74) for the bearing (36) are machined into the gear (6), whereas the inner raceways (52, 54) are machined into the pin (34). The bearing (36) also has rolling elements (82) organized in two rows between the inner and outer raceways. The pins (34) have mounting ends (40, 42) which lie beyond the ends of the planet gear (6) to anchor the planet assembly (B) in a carrier (8). The bearing (36), inasmuch as it is assembled separately, is set with considerable precision, preferably in preload, so the planet gear (6) does not skew with respect to sun gear (2) and ring gears (4) with which it meshes during operation at the epicyclic drive (A).

Abstract translation: 行星齿轮传动装置（A）的行星齿轮（6）集成到单独建成的行星组件（B）中。 每个行星组件（B）除了其行星齿轮（6）之外还包括延伸穿过行星齿轮（6）的销（34）和位于齿轮（6）和销（6）之间的减摩轴承（36） 34）。 用于轴承（36）的外滚道（72,74）被加工成齿轮（6），而内滚道（52,54）被加工成销（34）。 轴承（36）还具有在内滚道和外滚道之间以两排组织的滚动元件（82）。 销（34）具有位于行星齿轮（6）的端部之外的安装端（40,42），以将行星组件（B）固定在载体（8）中。 轴承（36）由于分开组装，所以其设计精度相当高，最好是在预压力下，因此行星齿轮（6）不会相对于太阳齿轮（2）和环形齿轮（4）偏斜 在行星齿轮传动（A）的运行期间啮合。
