  • Patent number: 4534095
    Abstract: In a cage for rolling bearings, the material of the webs is forced into the cage pockets on the outer surface of the cage, to hold the rolling bodies from falling out of the pockets radially outwardly of the cage. The material of the webs is also formed to provide the projections extending perpendicularly from the inner surface of the webs, in order to inhibit falling out of the rolling bodies radially inwardly of the cage pockets.

  • Patent number: 4526259
    Abstract: In a hydraulically operable release arrangement for clutches, especially for vehicle clutches, the release force is transmitted to the plate spring or the like of the clutch by way of a piston, a fixed bearing ring, a multiplicity of rolling bodies, and a rotating bearing ring. The piston is movably arranged in a housing and is biased by a helical spring arranged in a pressure space formed between the piston and the housing. The piston and the housing are each provided with an axial projection. In order to secure the piston against rotation and to damp vibrations in the piston without additional machining or special parts, the helical spring is arranged with its spring ends abutting the axial projections such that rotation of the piston in the direction of rotation of the rotating bearing ring is prevented.

  • Patent number: 4516962
    Abstract: A tension roller for a drive belt is comprised of a two-part pin and a roller rotatably supported on the pin by a rolling bearing. One part of the pin is substantially solid and has a seating surface for receiving the inner ring of the rolling bearing. The other part of the pin is cup-shaped and extends over the seating surface to engage a side surface of the inner ring. An eccentric bore is provided in the pin for mounting the tension roller on a machine frame by means of a mounting screw. The eccentric bore, in the solid portion of the pin, extends to and separates the outer surface of the pin, whereby the mounting screw partially engages the inner ring of the bearing. The arrangement permits the maximum range of tension adjustments for the tension roller.

  • Patent number: 4511192
    Abstract: A support for a tension roller is comprised of two cup-shaped sleeves, oriented with their open ends in the same direction, and with an inner one of the cup-shaped sleeves extending into the other of the cup-shaped sleeves. The outer end of the inner cup-shaped sleeve is outwardly flanged, to define a clamp between the flange and the open end of the other cup-shaped sleeve for holding the inner ring of the tension roller bearing. The bottoms of the two cup-shaped sleeves are initially spaced, and are drawn together upon tightening of a mounting screw extending therethrough into a machine frame, in order to clamp the inner bearing ring between the flange and the open end of the other cup-shaped sleeve.

  • Patent number: 4509364
    Abstract: In a wear measuring arrangement for bearings, a support sleeve is slidably mounted in one of the bearing rings, and supports an inductive sensor having a plunger type armature with a probe tip. The support sleeve is mounted to be held in a position with the probe tip away from the other bearing part, and to be released by a control shaft. Upon release, a spring arranged in the bore of the support sleeve resiliently urges the probe tip to engage the other bearing part and pierce any grease layer on the surface thereof.

  • Patent number: 4505369
    Abstract: In a clutch throwout, particularly for automotive clutches, a self-centering clutch bearing is arranged on or in a sliding sleeve. The stationary bearing ring of the clutch bearing is connected with the sliding sleeve via an intermediate element, which features guides for the radial sliding, in two mutually crossing radial directions, of the clutch bearing in relation to the sliding sleeve.To enable the clutch bearing to slide in any radial direction and to position itself precisely centered in relation to the tongue ends of the clutch diaphragm spring, without great constraining forces, while, regardless of position, damping the relative movements of clutch bearing in relation to sliding sleeve, intermediate element is radially interlocked with the stationary bearing ring and with the sliding sleeve, in two mutually crossing directions.

  • Patent number: 4501114
    Abstract: The passage of material through a textile spinning or twisting machine is regulated through operation of a control element associated with the movement of said material. Light reflected from the moving material is converted into a variable electrical signal which is then modulated and used to operate a light-emitter. The modulated output of the light-emitter is sensed by a receiver located remote therefrom, but in direct-line-of sight, into an electrical command signal for operating the control element.

  • Patent number: 4489992
    Abstract: A self aligning bearing structure, especially adapted for electric motors, has an outer ring with a plastic jacket thereon. A housing for supporting a bearing has a cylindrical seat for receiving the outer ring. The plastic jacket has one annular central ridge of greater diameter, in the unassembled condition, than the seat, so that the annular ridge is compressed to substantially the compression limit when the outer ring is assembled in the seat. The plastic jacket may have a conical end to simplify assembly.
