Actuating drive with electric motor and gearing thereof

摘要

An actuating drive includes an electric motor and a gearing arranged in a housing which is open on one side and which is closed by a cover. The electric motor is mounted in a recess bulge of the housing which is substantially sealed off from the gearing. The configuration provides a precise positioning of the electric motor relative to a first axle, wherein a first gear of the gearing is assigned to the same and wherein the actuating drive can be manufactured more simply and more cost-effectively than was previously possible. This is achieved in that the electric motor is attached indirectly to the housing by means of an accordingly shaped metal sheet, and is positioned in a predetermined location with no radial or axial play.

主权项

1. An actuating drive, comprising:
an electric motor and a gearing, wherein the electric motor and the gearing are arranged in a housing which is open on one side thereof and which is closed by a cover, a recess bulge in the housing in which the electric motor is mounted, and which is substantially sealed off from the gearing, at least one pocket formed in the housing formed by a base extending inwardly from the housing and by opposing arms extending from either side of the base; at least one rib arranged in the at least one pocket, wherein said rib extends inwardly from the base or an arm of the pocket; a metal sheet indirectly attaching the electric motor to the housing, wherein the metal sheet is positioned in a predetermined location with no radial or axial play, and at least one tongue extending from said metal sheet, wherein each of said at least one tongue is received by a respective pocket, and wherein said at least one rib deforms to allow the pocket to receive the tongue therein, thereby securing the metal sheet with no radial play.
