Abstract
In a gear drive unit (10), in particular for adjusting moving parts in the motor vehicle, having a rotor shaft (18) supported in a housing (16) and braced axially on the housing (16) via at least one face end (50) and in which a separate toothed element (32) for transmitting torque to a gear component (38, 40) is secured to the rotor shaft (18), the toothed element (32) has an axial bearing face (48) that rests on one of the face ends (50) of the rotor shaft (18).
Claims7
A gear drive unit (10) for adjusting moving parts in a motor vehicle, comprising:
- a rotor shaft (18), which is supported in a housing (16) and is braced axially on the housing (16) via at least one face end (50);
- and
- a separate toothed element (32) for transmitting torque to a gear component (38, 40), wherein said toothed element (32) has a worm gear (34) and is secured to the rotor shaft (18), wherein the toothed element (32) has an axial bearing face (48), which rests on the at least one face end (50) of the rotor shaft (18), wherein the toothed element (32) further has an axial bracing face (60), wherein said toothed element is braced on an adjusting element (64) on the housing (16), wherein said adjusting element (64) has a form lock (72) that is configured to be engaged from the inside of said adjusting element by a selected installation tool, wherein said adjusting element (64) presses with a predeterminable pressing force against the axial bracing face (60) wherein the axial bearing face (48) is located on a bottom face (46) of a bore (44) in the toothed element (32), wherein a through opening (52) is integrally formed onto the bottom face (46) of the bore (44) and receives a ball (56 that has the bracing face (60).
A gear drive unit (10) for adjusting moving parts in the motor vehicle, comprising:
- a rotor shaft (18), which is supported in a housing (16) and is braced axially on the housing (16) via at least one face end (50);
- and
- a separate toothed element (32) formed as a worm gear (34) for transmitting torque to a gear component (38, 40), wherein said toothed element (32) is secured to the rotor shaft (18), wherein the toothed element (32) has an axial bearing face (48), which rests on one of the face ends (50) of the rotor shaft (18), wherein a through opening (52) is integrally formed onto a bottom face (46) of a bore (44) and receives a ball (56) that has a bracing face (60), wherein said through opening (52) is configured to receive said ball (56) such that said ball (56) is axially accommodated over half of its diameter in said through opening (52).
