Abstract: 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.

Abstract: 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.

Abstract: A process for the production of a layer of hydroxyapatite (HA) on metallic and non-metallic bodies for implants is disclosed, wherein a layer of .alpha.- or .beta.-tricalcium phosphate (TCP) is applied and this is then completely converted into pure HA by reaction with water at an elevated temperature.

Abstract: Structural components, especially components having complicated configurations, are endurance tested for their creep resistance or strength in a removable massive metal testing block which encloses the component being tested in the manner of a mold. The mold type testing block is made of a high heat resistant metal acting as a susceptor in an induction heating system in which the testing block is surrounded by an induction heating coil. In this system the component being tested can be heated to high, highly constant temperatures which provides a substantial improvement in the creep testing results and reduces the cost of testing.

Abstract: 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.

Abstract: 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.

Abstract: A motor and a transmission housing are coupled by providing each with a housing face and clamping the housings together with a plastic seal disposed between the faces. Supply lines to the motor pass through an opening in the motor housing and are provided with an integral feedthrough which is molded or otherwise secured to the seal.

Abstract: The object of the invention is to develop an easily fabricated and assembled gear train arrangement, specifically a worm gear arrangement, which requires only a low overall height and at the same time assures operating reliability under extreme temperature ranges for application is motorized vehicle accessory drives such as power window lifts, wherein an output shaft mounted in a gear housing is linked in an elastic, slightly rotating connection to a worm wheel by way of a catch plate fastened to the output shaft, with the worm wheel being driven by a worm gear drive shaft which penetrates into the gear housing. In accordance with this invention the catch plate is designed as a single-piece plastic injection molding mounted onto the output shaft, with a first bearing bushing to mount the output shaft in the gear housing and a second bearing bushing mounted concentrically to the first bearing bushing to mount the worm wheel on the catch plate.

Abstract: An electric multiphase motor with a closed ring housing and a pole piece star which is inserted therein after being wound from the outside, the pole piece star having axially integral pole pieces which are arranged in star-like fashion around a hollow cylinder and inserted therein in which great strength of the pole star is achieved while at the same time ensuring good electrical data by inserting the radially inner ends of the pole pieces into the hollow cylinder as individual parts up to the bore of the hollow cylinder so that after the assembly of the motor no further finishing operations are required and welding the radially outer ends of the pole pieces to the inside to the surrounding ring housing by electron beam welding starting at the outer circumference of the ring housing.

Abstract: A motor drive for a window lifter in motor vehicle doors has an integrated flat housing containing a permanent magnet DC motor and a worm gear driven by a worm on the extended motor shaft; the housing has two halves which are separable in the plane of the motor axis and which serve as the return yoke of the motor.A single permanent magnet is arranged in the space defined on two sides essentially by the motor rotor on the one hand and the worm gear on the other hand and each of the two housing halves serves as a pole plate.

Abstract: A process for the production of a sodium-filled valve in which the sodium is introduced into a hollow valve stem through a filling bore of relatively large diameter and which is sealed through a plug and/or usual welding. Subsequent to the closing off of the filling bore, the hollow inner space is evacuated through a passageway having a small cross-section and is thereafter sealed vacuum-tightly in a vacuum through either welding or soldering. Through the evacuation of the hollow space there is avoided any kind of oxydation of the sodium and thereby any change. Moreover, no froth or foam formation is encountered so as to facilitate the presence of an extremely constant heat transfer.

Abstract: A commutator motor brush mounting arrangement is arranged in an axial opening of an electric motor housing. The arrangement is provided with mounting bars which protrude axially from a support plate, the mounting bars being arranged at the interior of the motor housing. Hammer-shaped brush holders which are formed with half-open bearing shells are rotatably engaged with the mounting bars. Axial displacement of the brush holders in a first direction is prevented by the front plate, and in a second direction by an end plate. The end plate is provided with elastic openings for engaging posts arranged on the mounting bars in a self-locking manner. The support plate and the end plate are provided with respective complementary guide portions in the form of support ribs and corresponding depressions. Such guide portions rotatably secure the hammer-shaped brush holders to the mounting bars, so as to prevent canting and binding of the brush holders within the motor housing.

Abstract: A motor vehicle hoist has a closed rope loop which is driven by a permanent magnet electric motor having a flat housing and a worm with a worm wheel. The worm is fastened to an end of the motor shaft which extends into an adjacent gear box, and turns a rope drum. The motor stator includes an axially oriented, magnetically nonconductive frame, which holds the rotor and at least one permanent magnet and which supports housing halves which serve, on both sides, as pole pieces. The worm wheel and rope drum are rotatably mounted on a common axis in the gear box. The motor is useful for opening windows, doors, and sliding roofs of vehicles.
