  • Patent number: 11873863
    Abstract: To provide an insulating rolling bearing that is capable of preventing electrolytic corrosion and preventing a gap from being undesirably formed between a shaft and a raceway ring. A sub bearing 21 includes an inner ring 22, an outer ring 23, balls 24 interposed between the inner ring and the outer ring, and an insulating bushing 28 fitted to an inner peripheral portion of the inner ring 22. The insulating bushing 28 includes a generally cylindrical metal base 28a, and a resin layer 28b formed on an inner peripheral surface of the metal base 28a. The insulating bushing 28 is fitted to the inner peripheral portion of the inner ring 22 such that the metal base 28a abuts on the inner peripheral portion of the inner ring 22.

  • Patent number: 10436250
    Abstract: To provide a retainer for a thrust bearing, which is to be assembled and decomposed regularly for being washed, having superior ball retaining performance itself and being attached and detached easily, and a thrust bearing having the retainer. A retainer for a thrust bearing 1, which retains a plurality balls intervened between a pair of raceway rings in a thrust bearing, is formed of a ring shaped plate member 2 formed of an injection molded body of a resin composition containing fluororesin, which is capable of injection molding, as a base resin. The ring shaped plate member 2 includes a plurality of ball pockets 3 in a circumferential direction of a ring shape. Each of the ball pockets 3 includes a claw portion divided into two portions 3a or more to retain a ball 5 in a detachable manner.

  • Patent number: 10100923
    Abstract: In a vehicle including an engine, drive wheels, a power transmission system, and an electronic control unit, during shifting of an automatic transmission, a hydraulic command value of a clutch is set to a higher value as an engine power command value is larger, so that a shift or change of the speed ratio proceeds in an electronic continuously variable transmission and the automatic transmission, in accordance with engine power as a product of the engine speed and engine torque, rather than torque of the engine, etc.

  • Patent number: 9810215
    Abstract: Provided is an internal gear pump requiring fewer machining steps, allowing inexpensive manufacture, and offering high safety from the standpoint of function. The internal gear pump 1 comprises: a trochoid 4 in which an inner rotor 3 having a plurality of outer teeth is eccentrically and rotatably accommodated in an outer rotor 2 having a plurality of inner teeth, the outer teeth meshing with the inner teeth, and in which a suction-side chamber for suctioning liquid and a discharge-side chamber for discharging liquid that has been suctioned into the suction-side chamber are formed in between the inner teeth and outer teeth; a casing 5 in which is formed a recess 5a for accommodating the trochoid 4; and a cover 6 for closing off the recess 5a of the casing 5. At least some of the casing 5 is a body injection-molded from a resin composition.

  • Patent number: 8864231
    Abstract: A bearing assembly for a worm drive supporting the worm of the worm drive with washer-shaped thrust slide bearings and bush-shaped radial slide (sintered oil-containing bearings) bearings. The thrust slide bearings are made of a resin containing 95 to 99.9 wt % of polyetheretherketone resin, which is an aromatic polyetherketone resin. Wear of the thrust slide bearings is reduced and its durability is improved, thereby preventing vibration and noise of the worm drive as well as improving its durability.
