A spindle drive (), having a gear housing () which is connected to a drive motor (), the gear housing () having a housing main body () and at least one housing cover () which is connected to the housing main body (), the housing main body () and the at least one housing cover () delimiting a receiving space () for a drive element () which interacts with the drive motor (), the drive element () being connected to a spindle () which penetrates the receiving space (), means () being provided, in particular in the form of a shaft ring, for arranging the drive element () in the receiving space () in a manner which is free from axial play, and the means being arranged in a receiving region () in the receiving space ().

Spindle drive, and comfort drive having a spindle drive

A spindle drive (), with a spindle () which is rotatable about a rotation axis () at least indirectly by a drive motor (), the spindle () having a thread-like spindle turn () on which a spindle nut () is arranged movably in the longitudinal direction of the rotation axis (), and with a worm gear () which is arranged in a gear housing (), is drivable by the drive motor () and is connected to the spindle () for conjoint rotation therewith.

Spindle drive, method for producing a spindle drive, and comfort drive

The invention relates to a spindle gearbox () of an electric seat drive, comprising a gearbox housing () for mounting a worm gear () and a worm, the worm meshing with the worm gear (), a threaded spindle () connected to the worm gear (), a first lid (), and a second lid (), wherein the first lid () and the second lid () are fastened parallel to one another on the gearbox housing (). The threaded spindle () is guided through the first lid (), and the first lid () is fastened on the gearbox housing () independently of the second lid ().

Spindle gearbox and drive unit of an electric seat drive

A transmission drive unit of a seat adjusting device, comprising an electrical drive motor (), a spindle drive () comprising a spindle () which is able to be driven by the drive motor (), a nut () which is connected to a first seat component, and a housing (), wherein the housing () is produced from a plastic material, the housing () comprises a first interface () for attaching to a second seat component, and the housing () comprises a first bearing surface () for bearing the spindle () of the spindle drive ().

Transmission drive unit of a seat adjusting device

A spindle drive (), drive spindle (), and a production method for such a spindle, particularly for a seat adjustment or a servo steering mechanism, having a spindle thread () for receiving a spindle nut (), wherein a drive gear () made from synthetic material is injection-molded in a non-rotatable manner on the drive spindle (), said cog having external toothing (), by means of which the drive spindle () can be caused to rotate, wherein within an axial extension () of the drive cog () the threaded spindle () has a recessed region () with a smaller external diameter () between two holding regions () with a larger outer diameter ().

Drive spindle and spindle drive and method for producing a drive spindle

A transmission drive unit () comprising a drive motor () having an output shaft () and an output toothing (), a threaded spindle () having a worm wheel () that is in engagement with the output toothing (), a first housing part () produced from plastic, having axial bearing locations () and radial bearing locations () for supporting the threaded spindle (), and a second housing part () produced from metal, having a through opening () for the through passage of the threaded spindle (), and at least one coupling region () for fixing the transmission drive unit () to a component.
