Abstract: An end play take up retaining ring between a support element and a retained element is constituted by a longitudinally split sleeve defining at a first end thereof a closed-biased C-shaped spring and at a second end thereof a larger open-biased C-shaped spring. The closed-biased C-shaped spring is expanded to fit the retaining ring over an external annular groove in the support element. At the same time, the open-biased C-shaped spring is squeezed to a smaller diameter. When the closed-biased C-shaped spring is released, it resiliently clamps the retaining ring in the annular groove. When the open-biased C-shaped spring is released, it resiliently expands and thrusts a beveled shoulder against the retained element. The beveled shoulder converts expansion of the open-biased C-shaped spring into relative lateral thrust which seats the first end of the retaining ring against an end wall of the annular groove and the retained element against a stop on the support element.

Abstract: A structurally improved double-bearing fishing reel is disclosed. In the fishing reel, the magnet unit is mounted in opposition to and spaced apart from the conductive wheel of the spool and radially moves relative to the conductive wheel thus adjusting the gap between the magnet and the conductive wheel and preventing backlash of the reel. The above magnet unit reduces the axial size of the reel and achieves the recent trend of being a compact and light reel. As the magnet unit is placed in a conductive wheel receiving magnetic case, the magnetic line of force is prevented from leaking. The present invention also reduces the number of parts of a holding unit, that is used for holding both a handle shaft and a spool shaft bearing, thus reducing the cost of the reel.

Abstract: A plain flanged bearing or bushing for supporting a rotating shaft in a thin walled frame of an electrophotographic printing machine. The composite bearing has a flanged end and is adapted to be inserted in an opening in a thin walled support member until the flange abuts the surface of the wall. A protruding tab formed by displacing a small portion of the flange extends in an axial direction along the bearing and cooperates with a corresponding opening in the wall to prevent rotation of the bearing. A friction push nut or snap ring is attached to the bearing on the side of the wall opposite the flange. The protruding tab prevents the bearing from rotating about an axis which can cause the bearing to be worn on the exterior surface by rotational contact with the thin wall. A shaft to support idler rolls or other rotating elements is inserted in an inner bore of the bearing and is rotatably supported thereby.

Abstract: A bearing retaining device is provided to maintain a shaft bearing within a housing. In one embodiment the device has a housing with a central bore into which is received a bearing. The bearing rests upon a bearing seat and is maintained in the housing by a retainer clip. The retainer clip is generally disc shaped with a number of spring tab members extending at an angle therefrom. When the retainer clip is rotated within the housing, the spring tab members are compressed by brush holders protruding into the housing and above the retainer seat. The spring tab members spring back to position after clearing the protrusions and dimpled ears formed in the retainer clip body frictionally engage the brush holders. The trailing edge of each spring tab member grips the side of each brush holder. The bearing is thereby locked into the housing and displacement and vibration thereof are eliminated.

Abstract: Thrust friction bearings with bent holding lugs wherein the holding lugs depressions are formed in the slide layer before the bending of the lugs. In one example, one shallow groove is stamped into an integral bracket forming a holding lug. In another example, several depressions are formed in rows, instead of grooves. The grooves or rows of depressions extend in a direction across the lug, preferably lying at an angle to the axis of curvature. Thus, when the holding lugs are formed by bending, damage to the slide bearing material will not occur.

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.

The ring has an open sector to allow for flexibility. In one embodiment, a number of lobes, defined by tapered inwardly declining surfaces extend from the ring and protrude from the groove into the bore. As a bearing is urged past the groove, the lobes are urged into the groove to allow the bearing to pass. Once the bearing has cleared the groove, the spring-like nature of the ring causes the lobes to again extend into the bore such that bottom surfaces of the lobes engage a top surface of the bearing, retaining the bearing and shaft assembly within the bore. In another embodiment, the ring has a number of lobes defined by tapered outwardly declining surfaces, while a third embodiment includes lobes defined by alternating inwardly and outwardly tapered declining surfaces.

Abstract: This invention relates to a thrust bearing arrangement in which a thrust bearing (17, 18) is brought to a given position on an axle or shaft (15, 16) and secured firmly in this position by means of a locking ring (23, 24) capable of being displaced along the axle or shaft. In order to enable this arrangement to be achieved quickly and easily, the locking ring has the form of a shrink ring (23, 24) which is heated to an appropriate temperature and then slid along a smooth part of the axle (15, 16). The shrink ring is dimensioned so that it will shrink firmly around the axle (15, 16) when cooled to normal operating temperature, so as to be immovable on the axle when subjected to axial forces occurring in operation. The thrust bearing (17, 18) is positioned, according to the invention, in a bearing seating, which enables the transverse insertion of a feeler gauge or corresponding device to provide a given clearance at a selected end of the bearing (17, 18) prior to shrink fitting the locking ring (23, 24).
