A bearing device for a vehicle wheel includes an outer member which is a plastic work piece in which an open hole in an outer-side end part is pushed out from inner sides, and an outer periphery of the outer member has a bulged part that is enlarged radially outward.

A lens barrel (10) comprises a holding frame (51); a guide pole (53); a focusing lens unit (52) that is slidably guided by the guide pole (53) and moves in an axial direction; an actuator that moves the focusing lens unit (52) in the axial direction relative to the holding frame (51); and leaf springs (55) that support the guide pole (53) so as to allow movement in the axial direction relative to the holding frame (51), at an amplitude smaller than the stroke of the focusing lens unit (52).

Among other things, a radiation system is provided. The radiation system includes a stationary unit and a rotating unit that rotates about an axis relative to the stationary unit. A radiation source and a detector array are mounted to the rotating unit. A wheel mechanism at least partially supports the rotating unit and facilitates rotation of the rotating unit relative to the stationary unit. A lift unit is supported by the stationary unit and engages the rotating unit. When the lift unit is in a lowered position, the rotating unit is supported by the wheel mechanism and the lift unit is spaced a distance apart from the rotating unit. When the lift unit is in a raised position, the rotating unit is supported by the lift unit and the rotating unit is spaced a second distance apart from the wheel mechanism.

A disk drive is provided with an enclosure and a disk mounted for rotation within the enclosure. The disk drive is also provided with a head mounted for rotation within the enclosure and adapted to engage the disk, a housing defining a cavity extending along an axis within the enclosure, and a shaft received within the cavity, mounted for rotation about the axis and coupled to one of the disk and the head. The disk drive is also provided with a bearing and a bearing seat. The bearing is formed generally spherical, oriented in a non-rolling configuration along the axis, and secured to one of the housing and the shaft. The bearing seat has a surface secured to the other of the housing and the shaft and biased to engage the bearing, wherein at least one of the bearing and the surface includes a low-friction coating formed thereon.

In a wave generator for a strain wave gearing, a plug outer peripheral surface of a rigid wave plug has a non-circular profile and is fixed to an inner-race inner peripheral surface of a wave bearing by press-fitting and using an adhesive. The plug outer peripheral surface is a groove formation surface in which microgrooves are formed as adhesive-retaining grooves that can retain the adhesive. When the wave plug is press-fitted into the wave bearing, the amount of adhesive that is scraped out from therebetween is reduced and the bonding strength therebetween can be increased while also preventing unevenness of the bonding strength.

The bearing provides an outer ring and an inner ring capable of rotating concentrically relative to one another. At least one of the inner and outer rings are split into a plurality of successive circumferential ring segments. Each pair of adjacent successive ring segments of the split-ring is secured together with at least one fixing plate. The fixing plate is disposed inside a first groove disposed on one of the ring segments and a second groove 38 disposed on the other ring segment. The fixing plate is set back or flush with at least the surface of each of the ring segments from which the first or second groove is formed.

The invention relates to a strain wave gear, having an outer ring with an inner toothing, with which a flexible inner ring with an outer toothing engages at two opposing points. The strain wave gear is characterized in that the ratio of the pitch diameter of the outer ring to the rim thickness of the outer ring lies in the region of 13 to 21, especially in the region of 17 to 19, especially at 17.587, wherein the teeth of the toothing of the inner ring have a profile angle in the region of 8 degrees to 15 degrees or in the region of 11 degrees to 12 degrees or one of 11.615 degrees, and/or wherein the teeth of the toothing of the outer ring have a profile angle in the region of 8 degrees to 15 degrees or in the region of 11 degrees to 13 degrees or one of 12.474 degrees.

Disclosed is an embodiment of a turbocharger roller support system that utilizes roller-shaft interfaces that are slanted to locate a turbocharger shaft with a turbine and compressor. Slanted contact surfaces on the turbocharger shaft are slanted inwardly so that the turbo shaft remains centered in the roller support system. The rollers entirely locate the turbocharger shaft, so that no bearings are necessary directly on the turbocharger shaft. The rollers spin at a slower speed than the turbocharger shaft, so can utilize lower speed bearings.
