Abstract: To simplify assembly and to reduce the susceptibility to faults of a linear drive comprising a transmission housing, an interference-suppressed electric motor which is connected thereto and is accommodated in a motor housing and which by way of a rotor accommodated in the motor housing drives a shaft which is mounted on a rear shaft end in a rear shaft bearing and is mounted on a front shaft end, a commutator for the transmission of current to the rotor, electrical and/or electronic components for interference suppression of the electric motor, it is proposed that the rear shaft bearing is mounted in the motor housing, the front shaft bearing is mounted in the transmission housing and the electrical and/or electronic components required for interference suppression of the electric motor are arranged on an interference suppression circuit board arranged between the front shaft bearing and the commutator.

Abstract: Linear drive with a gear housing extending along a longitudinal axis, in which a spindle is rotatably mounted with a worm wheel connected to it in a rotationally fixed manner, a spindle nut running on the spindle, which is adjustable on the spindle between a retracted position and an extended position and which acts on a lifting tube. The spindle nut is arranged in the retracted position guide tube and retracted in the region of a rear end of the guide tube, and thus the lifting tube is also retracted into the guide tube. The spindle nut is arranged at a front end of the guide tube in the extended position. An electric motor drives the screw, which extends along a transverse axis extending transversely to the longitudinal axis, wherein the electric motor is accommodated in a motor housing which is connected to the gear housing. Furthermore, a control system is arranged in a control housing.

Abstract: A linear drive having a transmission housing and an electric motor which is accommodated in the transmission housing and drives a shaft with a worm. The shaft meshes with a worm gear which is non-rotatably connectable to a clutch to a spindle holder non-rotatably connected to a spindle. The clutch is biased by a spring and is adjustable by a clutch actuation. The clutch actuation includes a slide element which bears against the clutch and which is arranged non-rotatably but axially displaceably. A rotary element which is axially fixed but rotatable about an axis of rotation engages the slide element at an outside that faces away from the clutch. Run-on bevels of complementary configuration are provided between the slide element and the rotary element. The rotary element is actuable by a pulling element, and the slide element is axially displaceably in relation to the rotary element.

Abstract: A linear drive comprising a transmission housing and an electric motor which is connected thereto and which drives a mounted shaft which in turn drives a worm which meshes with a worm gear which is non-rotatably connected to a spindle on which runs a spindle nut, arranged displaceably in a guide tube. Provided between the guide tube and the spindle nut to ensure correct rotary angle orientation of the spindle nut, in relation to the guide tube are inner barsa and complementary guide grooves. To simplify machine-assisted mounting of the spindle nut, in the guide tube there are provided positional orientation means which implement correct rotary angle orientation of the spindle nut, upon insertion thereof into the guide tube in the push-in direction.

Abstract: A linear drive comprising an electric motor driving a worm, a worm gear which meshes with the worm and which is connected non-rotatably to a spindle extending along a linear drive longitudinal axis or axis of rotation and which has a rear and a front end. The worm gear has a bearing seat for a rear bearing, with which the worm gear is mounted in a surrounding transmission housing. To simplify the manufacture of such a linear drive the invention proposes that the rear bearing is in the form of a fixed bearing, the spindle comprises a weldable material, a securing disk is arranged on the rear end of the spindle and the securing disk is connected to the spindle in bonded-material relationship.
