Abstract

A driving arrangement for moving at least one object, which is positioned movably inside a runner rail, in particular a sliding door, a sliding window, or a partitioning wall, comprising an electric motor (1) that drives a traction element (4) by way of a drive pulley (3) that is arranged at one end of the runner rail, which traction element circulates around a reversing device arranged at the other end of the runner rail and moves the object, characterized in that the rotor shaft for the electric motor (1) drives a driven shaft (6) by way of a gear (5). The axis (14) of the driven shaft extends at a right angle to the axis (13) of the rotor shaft and drives the drive pulley (3) by way of a transmission arrangement (9, 10, 11), wherein the gear (5) is positioned such that it can pivot elastically and at a specific angle around the axis (14) of driven shaft (6).

Claims

1. An electric motor drive comprising in combination;

an electric motor (1) with a rotor shaft, said electric motor operating a tractor (4) by way of a drive pulley (3) wherein the rotor shaft of the electric motor (1) drives a driven shaft (6) via a worm gear (5), said driven shaft in turn operates the drive pulley (3) via a transmission arrangement (9, 10, 11), said driven shaft having a rotational axis (14) that extends at a right angle to the axis (13) of the rotor shaft,

the electric motor (1), the rotor shaft, and the worm gear (5), driven by the rotor shaft, are installed together in a housing (7), said housing is mounted on elastic members that allow said housing to move in response to an inertial force applied to the worm gear 5 such that said housing elastically moves relative to the axis (14) of the driven shaft (6) in order to reduce the acceleration forces which act upon the electric motor (1) and the worm gear (5).

2. A driving arrangement according to claim 1, characterized in that the housing (7) is supported in at least three locations on elastic buffers (8).

3. A driving arrangement according to claim 1, characterized in that the housing (7) is positioned such that it can move around the axis of the driven shaft (6) with at least one bearing member and at least one elastic element that acts upon the housing (7) and determines the elastic range of movement of the housing (7).

4. A driving arrangement according to claim 1, characterized in that the driven shaft (6) drives the drive pulley (3) via a transmission arrangement (9, 10, 11), which transmission arrangement comprises a pulley (9) that is attached to the driven shaft (6) and operates,by way of a belt (10), a pulley (11), which is connected as one piece with the drive pulley (3), said pulley (11) together with the drive pulley (3) being positioned such that pulley (11) can pivot around an axis (12) that extends parallel to the axis (14) of driven shaft (6), wherein the bearings (15, 16) for the drive pulley (3) and the pulley (11) are elastic plastic sliding bearings.

5. A driving arrangement according to claim 4, characterized in that the belt (10) is designed as V-belt or as toothed belt and the pulley (9) and the pulley (11) are correspondingly designed as V-belt pulley or as toothed belt pulley.

6. A driving arrangement according to claim 4, characterized in that the driven shaft (6), the transmission arrangement (9, 10, 11) and the drive pulley (3) are installed together in a space adjoining the electric motor (1), the height of which space is lower than the diameter of the electric motor (1).

7. A driving arrangement according to claim 1, characterized in that the traction means (4) is designed as a V-belt, a toothed belt or as traction rope.

8. A driving arrangement according to claim 1, characterized in that the electric motor (1) is a direct-current motor that operates with low voltage.

9. A driving arrangement according to claim 1, characterized in that the gear (5) is a non self-locking worm gear.
