Planetary bearing for bearing planetary gears on planetary bolts in planetary drive of drive unit in motor car, has bearing ring arranged in rotary movable manner around rotation axis relative to planetary bolts and planetary gears

摘要

The bearing (1) has a roller bearing comprising rows of roller bodies, which are arranged around a rotation axis of the roller bearing. The roller bodies are radially arranged between planetary bolts (30, 35) and planetary gears (25, 34). The rows are arranged concentrical to each other. The rows are radially separated from each other via a common bearing ring. The bearing ring is arranged in a rotary movable manner around the rotation axis relative to the planetary bolts and the planetary gears. The roller bodies are commonly guided into cages. An independent claim is also included for a drive unit comprising an electro-motor.
