An adjusting drive having a gear housing sealed by a gear-housing lid, with a gear wheel or driver rotatably or sluably supported therein. An axial bearing neck is premolded on the gear-housing lid. A radial inner bearing projection concentric to the driver is premolded on the driver and provides a bearing arrangement inside the bearing neck. A radially outer bearing projection is also premolded on the driver and tangentially and sluably supports the gear wheel.

Adjusting drive, in particular a window-lift drive for a motor vehicle

To integrate electronics with a drive unit, given a simple manufacturing or assembly, and a compact type of construction, a printed-circuit board, which accommodates the electronic components and which is designed, at the same time, as a brush-holder plate for the commutator motor, is arranged, together with an electronic housing, parallel to housing flanges of a motor housing, of a gear housing. The printed circuit board of the drive unit, and is covered on its one axial side by the motor housing and the electronic housing, and on its other axial side by the gear housing thereby protecting it from external elements.

In the case of assembly after the insertion of the rotor (4-7) with the commutator (4) into the motor housing (8), in order to be able to install the brush holder (1), with its brushes (1.1; 1.2) which are subject to radial spring pressure, simply and in a manner which can be carried out by an automated machine it is proposed that: the brush holder (1) is pushed onto one end part (2.1) of an installation mandrel (2) which is in the form of a sleeve and whose other end (2.3) is placed on the commutator (4), together with an integrated restraining part (3) which holds the brushes (1.1; 1.2) in a raised installation position; and that the restraining part (3) is fixed outside the motor housing (8) by means of a conical expansion of one end part (2.1). The brush holder (1) is then moved into its final position with the brushes (1.1; 1.2) which now slide on the installation mandrel (2 ). The brushes (1.1; 1.2) are pressed radially onto the commutator (4) during the withdrawal of the installation mandrel (2).

Method for producing a commutator motor

Electrical lines for two axially located housings are molded into an inelastic carrier and covered at both faces of the carrier. A seal is injection-molded onto the inelastic carrier. In one implementation in which the carrier is disposed between a commutator housing and a gear housing, the inelastic carrier engages a brush holder that is inserted into one housing of the commutator motor. The design enables the electrical lines to pass into the interior of two axially located housings in a simple manner, while guaranteeing a reliable moisture seal between the housings.

Electric motor with watertight construction

A motor casing is provided which guarantees reliable run-off of condensation water from the inside of the casing to its outside, and which reliably prevents drop water from penetrating from the outside into the inside of the motor casing with a simple device. The motor includes a tab which is punched and bent from the casing pot base using a die provided for deep-drawing of the pot-shaped motor casing such that a run-off hole proceeding from the bottom edge of the motor casing upwards, with a drip-off tongue angled away downwards is obtained.

A window-actuator drive unit includes a driving disk, which is rotatably supported on an axle of the gear housing. The driving disk is placed in a rotational-slave relationship with the worm gear of a reduction gearing which is connected on the load side to an electric drive motor. The driving disk is connected to the worm gear by way of a damping separator and on its unattached end is a shaft collar which has outer teeth used for an interlocking, rotational-slave relationship either with a cable pulley of a cable window actuator or the driving pinion of an arm or scissors-type window-actuator. The inner teeth of both the cable pulley and the driving pinion correspond to the outer teeth of the shaft collar.

Window-actuator drive unit

In order to produce a window-actuator drive having assembly and service friendliness, particularly by providing a design which enables the gearbox unit to be easily exchanged, the drive is designed as two functionally separate units. A gear housing, a worm gear, and a housing cover which is sealed off from them both makes up a first unit. A cable housing with a cable pulley makes up a second unit. The subassemblies of the first and second unit can be assembled by means of notched, snap-fit connections.

Control drive particularly a window-activated drive for motor vehicles

In a window-lifting actuating drive where two cup-shaped housings enclose a driven worm gear coupled to a cable pulley, a flat seal is configured to seal the worm gear housing from ambient moisture both at the joint between the two housings and between the cable pulley housing and the worm gear. The flat seal is also formed to allow the seal to be prefit to the cable pulley housing and retained to the housing before the housing is assembled to other components of the actuating drive.

Motor vehicle window-lifting drive

An apparatus for limiting the axial play of the shaft of a motor drive mechanism wherein the precise setting of the axial play (&lt;&lt;0.05 mm) is possible in a simple manner using production and assembly technology. A deformable guard plate, which is secured on its marginal side by a setscrew, in particular a standard production screw, is axially pressed in a contact zone until the desired axial play is achieved. The setscrew is axially supported in front on the case side.

Configuration for limiting the axial play of the shaft of a motor-drive

For a simple adjustment, suitable for automation, of the axial play between the rotor (1, 2) and the stator (5 to 8) of a miniature electric motor, at least one bearing (3) is axially moved relative to its bearing sleeve (51) in the end bell (5) and is fixed in its adjustment position by deformation of the bearing sleeve in a form-locking manner. For axial fixation, especially when used for drives with large axial loads, a thrust shoulder (511, 512) is formed after the axial play is adjusted for the axial contact of the adjusted bearing (15) from the bearing sleeve (51) by hot molding, ultrasonic heat deformation. Alternatively, precut tabs may be formed on the sleeve by embossing to form a thrust shoulder.

Method for adjusting the axial play between the rotor and a motor

The disclosed clamping plate exhibits a particularly great spring action and it includes a clamping rim (10) and with spring tabs (20) which point radially inward and against which the cups of the self-aligning or cup-type bearing make contact. According to the invention the spring tabs (20) are particularly long and extend from the clamping rim (10). The tabs also bend inwardly over a bead (9) limiting the clamping rim (10). An especially inexpensive design from the aspect of production engineering and assembly is achieved in that the transition from the bead (9) to the plug-in hole (2) is rounded in the plug-in direction (6) of the clamping plate and the lower area of the bead (9) is designed as oil collecting groove.

This invention develops an automated procedure which permits the settling of the axial play of a rotor using a stator sleeve pressed onto the rotor shaft and held in place during assembly by an insulating end disc which mates at an end face with the laminated rotor core, whereby assuring the smallest number of assembly steps. According to this invention, the insulating end disc is injection-moulded in one piece along with the spacer sleeve with an intermediate weak rated point in the form of either elastic or break-away intermediate segments which permit a relative setting motion between the insulating end disc which contacts the end face of the laminated rotor core, and the spacer sleeve pressed on the rotor shaft. This invention is particularly suitable for small commutator motors with rotor shafts mounted in sleeve bearings.

Device and procedure to adjust the axial play between the rotor and the

The object of the invention is to provide a means of limiting the axial play of a motor shaft while dispensing with the use of an adjustable stop screw that has to be secured separately after it has been set. In particular, and apparatus is provided that can be used with automated manipulators. For this purpose it is recommended, according to the invention, that as a stopping element a single piece disk of appropriate thickness or a single piece disk stamped parallel to the motor assembly machine out of strip material, with an axially stamped depression of appropriate depth, is to be inserted rigidly in a pocket fixed in the housing. The invention is particularly well-suited for application in small motors with a shaft mounted on plain bearings.

A brush assembly (2) with a plug housing (3) is inserted into an axial opening of a motor housing (1) so that interference suppression devices (5, 6) can be connected easily from a production point of view and the plug terminals and the brush apparatus can be protected against corrosive media. The plug housing is formed with pockets which hold the interference suppression devices and the plug terminals for easy assembly.
