    Abstract: The magnetic attraction force of an electromagnetic coil in an electromagnetic clutch is increased in a limited installation space, thereby improving reliability of operation. The dimensions of a field core housing the electromagnetic coil and a rotor are optimized to increase the magnetic attraction force. The thicknesses of cylindrical portions on the inner-diameter side of the field core and the rotor have larger thicknesses than those of cylindrical portions on its outer-diameter side so that the sectional areas of both cylindrical portions will be equal to each other. Also, a rotation transmission device provided with an electromagnetic clutch is proposed which can avoid deterioration of its sealing property and damage to its bearing and avoid cost increase.

    Abstract: A device for mechanically changing over the direction of transmission of turning force in which engaging elements are mounted between its driving member and driven member. It prevents the generation of abnormal noise resulting from the repeated engagement and disengagement of engaging elements when turning force is applied from the driven member. Sprags and sprag-supporting retainers are provided between an outer ring as driven member and an inner member as driving member. Also an elastic member is mounted between the outer ring and the inner member. When turning force is transmitted from the outer ring to the inner member, the inner member and one of the retainers begin rotating first, biased by the elastic member. The retainers thus rotate relative to each other, inclining the sprags in the same direction as the inner member to a ready-to-engage position. The sprags are thus prevented from repeatedly engaging and disengaging, so that there will be no abnormal noise.

    Abstract: An autotensioner for adjusting the tension of a timing belt used with an automotive engine. It includes a cylinder case filled with a hydraulic oil, a piston partitioning the interior of the cylinder case into a pressure chamber and a reservoir chamber and a push rod having its bottom end coupled to the piston and the top end adapted to protrude from the cylinder case. A spring is provided to bias the piston and the push rod upwardly. The pressure chamber communicates with the reservoir chamber through a channel formed through the piston. A plate-shaped check valve is provided in the pressure chamber to open and close the bottom of the channel. The plate-shaped valve can respond quickly to the fluctuation of pressure in the pressure chamber because of its reduced mass. Thus, when the piston and the push rod rise biased by the spring, the valve can move quickly to such a position as to open the channel, thus allowing the hydraulic oil in the reservoir chamber to flow quickly and smoothly back into the pressure chamber. This will prevent cavitation in the pressure chamber. The responsiveness of the valve will be improved further by providing another spring for biassing the valve in such a direction as to open the channel.

    Abstract: A linear motion actuator includes an outer ring member mounted in a housing, a rotary shaft rotated by a motor, planetary rollers mounted between the outer ring member and the shaft and supported by a carrier rotatable about the shaft. A helical rib is formed on the inner surface of the outer ring member which is engaged in helical grooves formed in outer surfaces of the planetary rollers. When the shaft rotates, the planetary rollers rotate and revolve, thereby axially moving the outer ring member. Uneven axial loads applied to the planetary rollers from the outer ring member are supported by thrust bearings disposed between the planetary rollers and an inner disk of the carrier. Aligning seats are provided between each opposed pair of the planetary rollers and the thrust bearings such that the contact surfaces of the aligning seats shift relative to each other under the uneven axial loads.

    Abstract: An electric linear motion actuator is proposed which includes planetary rollers mounted between the radially inner surface of an outer ring member and the radially outer surface of a rotary shaft, and a carrier rotatable about the rotary shaft and including radially movable roller shafts rotatably supporting the respective planetary rollers. Elastic rings each having circumferentially separate ends are each wrapped around the roller shafts to radially inwardly bias the roller shafts, thereby bringing the respective planetary rollers into elastic contact with the radially outer surface of the rotary shaft. Each elastic ring is prevented from rotating relative to the roller shafts, thereby preventing one of the roller shafts from being axially aligned with the gap between the circumferential separate ends, causing the elastic ring to be radially compressed and thus making it impossible for the elastic rings to radially bias the roller shafts.
