Abstract: A bearing assembly wherein the inner diameter of the slotted compressible annular locking collar is provided with a protrusion which extends radially inwardly, and finger extensions of the inner ring are provided with a recessed groove which extends at least partially along the collective outer annular surface of the finger extensions. When the locking collar is disposed about the finger extensions of the inner ring, the protrusion is disposed within the recessed groove to retain the locking collar on the inner ring. The inner ring finger extensions and the locking collar are relatively sized such that when they are in their free states, the inner diameter of the protrusion is slightly smaller than the outer diameter of the recessed groove, such that the collar may be snapped over the finger extensions and into proper position on the inner ring prior to installation on a shaft. The protrusion may be an integrally formed part of the locking collar or a separate resilient member. In one embodiment, the locking collar and finger extensions are formed with cooperating threads.

Abstract: A compressor bearing assembly for use in a compressor comprises an anti-friction rotation bearing and a compressor component. The anti-friction rotation bearing has a first and second side. The compressor component has a bearing press fitting hole. The bearing press fitting hole has a mouth and a bottom and is formed in the compressor component and is adapted to receive a first side of a rotation bearing. The bearing press fitting hole has a first inner diameter at its mouth and a second inner diameter in the vicinity of its bottom. The first inner diameter is less than said second inner diameter. The structure for the compressor bearing in this invention may strongly and uniformly fixes the rotation bearing. Further, this structure prevents the rotation bearing from slanting within the pressing hole and prevents undesirable adherence between the rotation bearing and the press fitting hole. As a result, the durability of the rotation bearing and the shaft are improved.

Abstract: A reliable bearing wheel assembly comprising a shaft, an inner race, an outer race, and rollers or other bearing elements between the inner and outer races, wherein the inner race is reliably prevented from both rotating and moving axially relative to the shaft, even when there is bearing failure. A first pair of axially extending grooves are provided in the outer surface of an end portion of the shaft and in the inner surface of the inner race respectively which in combination define a first keyway. A second pair of axially extending grooves are provided in the outer surface of the shaft end portion and in the inner surface of the inner race respectively which in combination define a second keyway. A first key is received in the first keyway. A fastener having a threaded shank portion threadedly engages a threaded bore which extends axially in the shaft end portion. A head portion of the fastener engages the inner race and at least partially covers the first keyway to block escape of the first key therefrom. A second key is received in the second keyway, and a portion thereof extends axially outwardly of the second keyway and abuts the head portion to prevent turning of the fastener to prevent loosening thereof as well as to prevent uncovering of the first keyway and escape of the first key therefrom.

Abstract: In a bearing device in which a free end of a shaft body to which a rolling bearing is mounted is bent outward in its radial direction into a shape to be pushed against an end face of an inner ring of the rolling bearing so as to prevent the rolling bearing from falling out, a raceway surface of the inner ring of the rolling bearing is subjected to hardening treatment, and other portion of the inner ring is made of row material which is not hardened. With this arrangement, the caulked portion formed by the caulking plastically deforms the relatively soft inner peripheral corner of the inner ring and as a result, the caulked portion and the inner peripheral corner are adhered to each other strongly.

Abstract: A method for fixing at least one bearing in a depression of a bearing retainer involves deforming a portion of the bearing retainer to cause a portion of the bearing retainer to form an overlapping connection of the bearing which axially retains the bearing in the depression. In the first stage of the two-stage deformation process, a first partial area of the bearing retainer is deformed compress the material forming the bearing retainer. In the second stage of the deformation process, a second partial area of the bearing retainer is deformed to form the overlapping connection, in the axial direction, between the bearing and the bearing retainer.
