摘要： A pivot bearing assembly comprises a shaft having a main body portion and a reduced portion integrally and coaxially formed therewith, an outer ring-sleeve member coaxially surrounding the shaft, a first bearing arranged between the reduced portion of the shaft and the outer ring-sleeve member, a second bearing arranged between the main body portion of the shaft and the outer ring-sleeve member and a tolerance ring mounted on the outer peripheral surface of the outer ring-sleeve member. The inner ring of the second bearing is a part of the main body portion of the shaft. The outer ring-sleeve member can comprise an outer ring and a sleeve tightly mounted on the outer ring or an outer ring portion and a sleeve portion surrounding the outer ring and integrally formed therewith.

摘要： The closed end 11b of the Sleeve 11 and the shaft end 12b are made to be point-contacted through the ball 14. By this point contact, while allowing the sleeve 11 and the shaft 12 to rotate, the pressurization in the axial direction between the sleeve and the shaft can be received. Further, by giving this pressurization, the inner ring 13a of the bearing 13 is displaced toward the axial direction (downward in FIG. 1) interposing the ball 13b to absorb the play of the bearing 13. Accordingly, even though merely one bearing 13 is used, the sleeve 11 and the shaft 12 are prevented from being deflected, to obtain the pivot assembly 10 having a necessary rotation precision.

摘要： The bearing device contains two rolling bearings installed on a shaft 9 and a preload is applied to the inner ring of the rolling bearings. The respective dimension for the two rolling bearing inner rings is shortened on both sides in the orientation of the width dimensions of the inner ring, centered on the grooves for the inner ring, with each being set smaller than the dimension of the outer rings. The difference in dimensions is double the difference in the dimensions capable of eliminating rattling of the rolling bearings, when a preload is applied to the outer edge of the inner ring. The outer rings and races are respectively formed to be in a position at half the width dimension of the inner ring from the outer edges of the two outer rings for the two rolling bearings.

摘要： A pivot bearing of the present invention comprises inner rings, outer rings surrounding the inner rings and rollable balls arranged between the inner and outer rings. This pivot bearing does not have a sleeve which is provided on the outer rings of a conventional pivot bearing. Each of the outer rings is made thicker substantially by the thickness of the sleeve of the conventional pivot bearing than the outer rings of the conventional pivot. The other components of the pivot bearing according to the present invention than the outer bearings use commercially available components or standardized components manufactured in the ordinary manufacturing line at ball bearing manufacturers' factories. Thus, a simple, inexpensive and precise pivot bearing can be manufactured.

摘要： A variable reluctance resolver has a rotor with magnetic poles with 2× or greater axis combination angles, and is structured so that reliable and accurate zero point detection can be carried out. Concave and convex portions are provided on at least two, but fewer than all, of the magnetic poles of the rotor, and the zero point detection winding is provided on a plurality of electrical poles of the stator. Two or more zero point detection signals are generated simultaneously by a plurality of zero point detection windings. Therefore, even if a portion of the zero point detection signals is lost, the zero point can still be identified based on the correlation between the two or more zero point detection signals.

摘要： A rotation angle sensor and a method of winding a rotation angle sensor involve a single electrical wire that is wound from a rotor transformer to a magnetic rotor. The magnetic rotor is axially spaced on a shaft from the rotor transformer. A notch is formed in a wall of a bobbin of the rotor transformer to permit the wire to pass from the rotor transformer to the magnetic rotor. The ends of the single wire are electrically connected together at a junction, and the junction is fixed to the rotor transformer with resin.
