The invention is characterised by the following features: a starting unit is provided for absorbing the axial loads of the driven shaft; the starting unit comprises a secondary axial bearing; the starting unit is formed in such a way that when said unit is actuated, the axial loads of the driven shaft are substantially completely absorbed by the secondary axial bearing.

Abstract: A transmission comprising a housing at least one shaft mounted in the housing such as to be rotatable; and at least one shim by means of which an axial play and an axial biasing of the shaft in the housing or between components arranged on the shaft may be adjusted. Said shim is formed from a wire bent into a ring.

Abstract: An endplay adjustment system and method is shown having a slider body that has a thrust surface that lies in a plane that is generally perpendicular to an axis of an armature and that can be driven toward the armature by a plunger body. After the plunger body is driven into a plunger-receiving area of the housing, an angled surface of the plunger engages a mating surface of a slider body which forces the thrust surface into an end of an armature of an electric motor. The plunger body may then be secured, adhered to or welded to the housing and/or the slider body to lock the slider body and plunger into place, thereby reducing or eliminating endplay associated with the armature shaft.

Abstract: A system and method for facilitating the reduction or elimination of end play associated with an armature in an electric motor is disclosed. The system and method utilize an end play assembly which includes a housing having an integrally molded lock for retaining a screw in an unengaged and locked position. The end play assembly also includes a coil spring which urges the screw towards an engaged and unlocked position when the end play assembly is mounted in a housing of the electric motor. The lock includes at least one wing portion which engages a notch on the housing of the electric motor such that when the end play assembly is mounted in the motor housing, the notch forces the lock into the unlocked position which releases the screw so that the spring can urge, rotate or screw the screw to cause a screw end to be forced into engagement with the end of an armature of the electric motor.

Abstract: An adjustable bearing assembly includes a bearing housing and a bearing body fixed to a carrier and disposed within the housing. Set screws are provided to adjustably position the carrier, hence the bearing body relative to the housing without disassembling the bearing. After the bearing body position has been adjusted, cap screws are employed to fix the carrier against movement relative to the housing and relative to a support surface. In an alternate embodiment, the carrier is in engagement with an inner eccentric ring which, in turn, is engaged by an outer eccentric ring, both rotatably mounted within the housing. The axes of the eccentric rings are spaced from one another and are parallel to the axis of the rotating shaft. Rotation of the eccentric rings relative to one another and to the housing adjusts the position of the bearing body.

Abstract: In a vertical-axis waterpower machine, the shaft is mounted in a bearing-supporting star. It has a track ring for a supporting bearing. Supporting-bearing segments are supported via adjusting elements on a supporting ring firmly connected to the bearing-supporting star. To simplify the construction and improve the accessibility of the adjusting elements, the latter are designed as rocking levers. The rocking levers act as single-armed or double-armed levers and are elastic in the lever longitudinal direction.

Abstract: A spindle motor has a rotor supported by a stator through a thrust bearing and a radial bearing. At least the thrust bearing is a hydrodynamic bearing. The spindle motor is provided with a device for adjusting the thrust laod that is applied to the thrust bearing. The load adjusting device has an electromagnet that is provided on the stator and a permanent magnet that is provided on the rotor in opposing relation to the electromagnet. Either the repelling force or the attraction force, which acts between the electromagnet and the permanent magnet, is controlled by changing the current supplied to the electromagnet.

Abstract: A high-speed drilling or milling spindle (10) comprises a stator (11) that can be attached to a machine tool (12), a rotor (13), and a rotary drive (40, 41) acting between stator (11) and rotor (13). The rotor (13) has a receptacle (15) for a rotating, metal-cutting tool (16). The rotor (13) is supported with respect to the stator (11) by means of at least a first and a second rolling bearing (22, 32) spaced axially away therefrom. The rotor (13) is supported on thrust and radial bearings. The rolling bearings (22, 32) have a very small thrust angle (24, 34). They essentially act as radial bearings. A third bearing is provided as the thrust bearing in the form of a magnetic bearing (50). The magnetic bearing (50) is adjustable in terms of its axial bearing force as a function of the axial forces (F.sub.a) acting on the tool (16).

Lateral space between the stationary yoke finger faces and the rotating groove walls is adjustably filled by cam displaced disc pads confined within yoke finger guide bores. Selective cam rotation expands the disc pad assembly for operational wear accommodation.

Abstract: Box machine forming wheels are individually stabilized with a respective, frame mounted, stationary yoke disposed within the circumferential groove of a head wheel that is rigidly secured to the forming wheel. Lateral space between the yoke finger faces and the rotating groove walls is adjustably filled by rub plates mounted on dowel pins confined within yoke finger guide bores. A cone tipped adjustment screw cooperates with conical tips on the dowel pins to selectively expand the rub plate assembly for operational wear accommodation.

Abstract: To adjust axial and radial movement of a thrust plug associated with end play of a rotating shaft, the thrust plug receives the shaft on one side and has a shoulder surface extending from the other side of the thrust plug. A housing position supports a retainer cap which receives the thrust plug so the thrust plug can have some axial movement. The thrust plug shoulder is higher than the thickness of the retainer cap, so that predetermined amount of axial play (c) can be accurately and exactly established. Radial movement of the thrust plug within a housing cavity is achieved by having a thrust plug diameter which is smaller than the inner diameter of the housing cavity, and having an O-ring about the thrust plug which engages the housing cavity and provides a pivot point.

Abstract: A portable lathe tool includes fixed and rotating split rings, the fixed ring arranged to be secured to a pipe workpiece, the rotating ring being relatively rotatable with respect thereto for carrying a tool capable of performing a machining operation on the workpiece as it is driven around the circumference of the latter. A bearing arrangement for supporting the relatively rotating ring on the fixed ring is disclosed as having a plurality of discreet, circumferentially spaced bearing segments, each having converging radial and thrust bearing surfaces for engaging the rear end area of the rotating ring for axially, radially and rotationally locating and guiding the rotating ring relative to the fixed ring. An adjustment system is provided for accurately locating and adjusting the position of each of the bearing segments ring relative to the fixed ring to permit compensation for wear and dimensional variations.

Abstract: A direct drive motor is disclosed comprising a base, an upright housing mounted on the base provided with bearings at the upper and lower end portions, and a capstan spindle held by the bearings, wherein one of the bearings is fitted screw-displaceably in the upper portion of said housing and provided with a hole receiving the upper end portion of the capstan spindle, held rotatably therein in both radial and thrust directions.

Abstract: A vertical post is rotatably mounted in a corner cabinet and supports a plurality of rotatable shelves which carry the cabinet door. The lower end of the post is rotatably supported by a lower bearing element which rests on a bearing member on the bottom wall of the cabinet. To enable the post and the door to be adjusted vertically, the lower bearing element is a slide supported for up and down movement in the post and having a downwardly inclined ramp on its upper end. A downwardly inclined screw extends perpendicular to the ramp and may be tightened and loosened to shift the slide downwardly and upwardly relative to the post. The head of the screw is sunk within the post to enable the shelves to be slipped onto the lower end of the post during assembly and to enable one of the shelves to pass upwardly by the location of the screw.

Abstract: The end of an axle spindle is provided with right hand and left hand threads to receive respective axle nuts. The inner nut thread diameter is larger than the outer nut thread diameter in order to avoid interference. The wheel, bearings and an inner nonrotatable washer on the axle spindle are secured in place by tightening the inner nut to an initial snug (no clearance) condition against the face of the nonrotatable washer. One of eight holes on the outer face of the inner nut receives a projecting pin of a spacing control device which pin projects a predetermined distance. The outer nut is turned until the spacing control device engages one of the eight recesses. Then the flats of both nuts are tightened by a spanner wrench which causes the inner nut to "back off". The method is to create a space between nuts (e.g. by use of a shim spacer) which converts to an appropriate clearance space between the inner nut and nonrotatable washer in the final condition and to maintain that space in the final condition.

Abstract: A rotary shelf assembly having a plurality of shelves mounted on a vertical post is disposed in a cabinet frame with upper and lower bearing elements supported at opposite ends of the post and coacting with vertically spaced bearing members which are secured to the cabinet frame to support the post for turning about its longitudinal axis. The assembly is adapted to be mounted in the corner of the cabinet frame and, to accommodate this, the shelves have perpendicular edges which generally align with the sides of the cabinet in one angular position of the post and which support a V-shaped door. To adjust the vertical position in the cabinet frame, the lower bearing element is on a slide in the lower end portion of the post and a manual actuator on the post moves a cam which cooperates with a cam follower on the slide to move the slide and hence the lower bearing member downwardly relative to the post.

Abstract: Means are disclosed for adjusting motor end play such that, despite variation from motor to motor in the distance between front and rear bearings on so-called skeleton motors, the end play can in all cases be brought to a minimum predetermined value. A lockwasher is positioned on the shaft by an arbor press that is referenced to a shoulder of the stator bearing assembly, thus compensating for length variations in stator manufacture.
