Abstract:
A servo drive for activating a tailgate of a motor vehicle has a drive, a sun wheel driven by the drive and rotatably mounted on a first axle, and a planetary wheel rotatably mounted on a second axle. The sun wheel engages with the planetary wheel. The first and second axles have ends, are movably arranged at their ends facing away from the drive in a common web, and are spaced apart from one another by a constant distance. The planetary wheel engages in a ring gear segment which is fixedly connected to a bodywork, and an end of the web, which faces the ring gear segment, is movably connected to a connecting rod through a third axle. An end of the connecting rod facing away from the third axle is movably connected, via a fourth axle, to an output element which is connected by an end facing away from the fourth axle to the tailgate.

Abstract:
The linear actuator has a motor housing (1) of tubular stainless steel with an end cap (2), a motor (4) and epicyclic gearbox (6). The actuator has a telescopic arm (11), having an outer tube (12) and an inner tube (13) of stainless steel. The outer tube is removably attached to the motor housing. An extension screw (16) is provided in the arm with a driven end (16) journalled at the motor housing end (17) of the outer tube. At its inner end, the inner tube has threaded into it a plastics material nut (18), in which the screw engages. The end of the screw (16) has a clevis (23), open (24) axially away from the screw. The output shaft (7) from the gear box has a cross pin (31) through it. On each side of the shaft, the pin carries a respective roller (32), sized to fit in the clevis (23). The clevis and rollers form a dog clutch for transfer of drive from the gearbox to the extension screw. The telescopic arm is readily dismounted from the motor housing by unscrewing the disc (21) and axially withdrawing the clevis from the rollers.
Abstract:
An elevator system includes an elevator cab having doors that are movable between open and closed positions. A rail is mounted to the cab. At least one roller defines an axis of rotation and is mounted for movement along the rail. The roller is operably connected to the doors to move the doors between open and closed positions. A motor assembly is mounted for movement with the roller along the rail and has an output for providing a rotational driving force to the roller. In one embodiment, the motor drives a planetary drive assembly which drives the roller along the rail and in another embodiment the motor drives a worm gear assembly which drives the roller. Alternatively, a tree-axis torque motor generates a magnetic field that is non-perpendicular to the axis of rotation of the roller, which causes the roller to be driven along the rail.
Abstract:
A window lifting and lowering apparatus that includes an arm pivotally moved to lift and lower a window of a vehicle. A cycloidal speed reducing mechanism is used for transmitting a rotational force of a drive shaft to the arm at a reduced speed. The cycloidal speed reducing mechanism includes a ring gear disposed in a fixed state, a planetary gear eccentrically rotated in a state of being brought into mesh with the ring gear by the rotational force of the drive shaft, a rotating disk for transmitting rotation of the planetary gear to the arm, and a stopper gear fixed to the ring gear for restricting a pivotal movement position of the planetary gear. In accordance with the eccentric pivotal movement of the planetary gear, a stopper pin provided on the planetary gear is made to impinge with a stopper projection provided on the stopper gear.
Abstract:
The present application discloses an axial operator that is configured for use with a door assembly. The axial operator comprises a rotatable operator output member that rotates about an operator axis, the operator output member being constructed and arranged to be operatively connected within the door assembly such that the operator output axis extends generally vertically. An electric motor has a rotatable motor output member that rotates about the operator axis. The motor is constructed and arranged to selectively rotate the motor output member about the operator axis. A reduction transmission is connected between the motor output member and the operator output member. The reduction transmission is constructed and arranged such that the transmission rotates the operator output member at a lower rotational speed than a rotational speed at which the motor rotates the motor output member and applies a higher torque to the operator output member than a torque which the motor applies to the motor output member. The reduction transmission comprises (a) an orbit gear, (b) a planet gear carrier, and (c) a planet gear. The motor is adapted to be communicated to a controller so as to receive a door moving signal therefrom and being further adapted to selectively rotate the motor output member in response to receiving the door moving signal to thereby rotate the operator output member so as to move the door panel with respect to the doorway as aforesaid.
Abstract:
A method and apparatus for counterbalancing a roll-up door uses a conventional coil spring having adjacent coils engaging each other. The spring is elongated to provide for spring growth during the winding of the spring. A worm gear box operates to wind the elongated spring and retain the spring in the wound position to continuously apply torsion force to a shaft operatively connected to the door the counterbalance the door.
