Abstract

A planetary gear set has a sun gear, multiple planetary gears mounted on a planetary carrier, and a ring gear enclosing the planetary gears, which is designed in split form perpendicular to its axis of rotation and is formed from two ring gear parts arranged coaxially to each other. An adapter component that, for the purpose of a torque-transferring or torque-supporting operative connection of the planetary carrier, is connected in a torque-proof manner to an additional component in a mounted state with the planetary carrier, and is guided, viewed radially, outward by the ring gear parts.

Claims

1. A planetary gear set, comprising:

a sun gear;

multiple planetary gears mounted on a planetary carrier;

a ring gear enclosing the planetary gears, the ring gear designed in split form perpendicular to its axis of rotation and formed from two ring gear parts arranged coaxially to each other;

an adapter component mounted to the planetary carrier and, for the purpose of a torque-transferring or torque-supporting operative connection of the planetary carrier, is engaged in a torque-proof manner to an additional component and is guided, viewed radially, outward by the ring gear parts;

a torque-proof, positive-locking connection between the adapter component and the planetary carrier in a mounted state of the adapter component on the planetary carrier; and

wherein the adapter component, in a mounted state with the planetary carrier, is connected to the planetary carrier by means of axially extended fingers, the fingers gripping between toothing arranged in the circumferential direction on the planetary carrier, between the planetary gears, wherein a torque-proof connection between the adapter component and the planetary carrier and centering of the adapter component are achieved.

2. The planetary gear set according to claim 1, wherein the adapter component is axially fixed by a retaining ring that is mounted in a groove in the planetary carrier and in the adapter component.

3. The planetary gear set according to claim 2, wherein an end of the adapter component turned away from the planetary carrier is configured to connect to a second additional component or a torque-transferring or torque-supporting operative connection between the planetary carrier and the additional component.

4. The planetary gear set according to claim 1, wherein the adapter component comprises a disk-shaped structural element that is guided, viewed radially, outward by the ring gear parts.

5. The planetary gear set according to claim 1, wherein the adapter component is designed in one piece with an L-shaped cross-section.

6. The planetary gear set according to claim 1, wherein the adapter component is connectable to or designed in one piece with the additional component.
