Abstract: A bearing device includes a slidemember made of porous-sintered-metal for slidably supporting a rotational shaft, and a holding member made of the same porous-sintered-metal and holding the slide member. The two members are constructed of the same material, and yet the density of the slide member is greater than that of the holding member so that lubricating oil is supplied continuously from the holding member to the slide member due to the capillary phenomenon. The bearing device constructed as above prevents the lubricating oil from flowing out, improves abrasion-resistance, and thereby extends the service life. Further, this construction allows the bearing device to be smaller and thinner.

Abstract: This invention relates to a toroidal type continuously variable transmission in which a plurality of power rollers are squeezed between an input cone disk and an output cone disk which are arranged upon the same axis of rotation. The gyration angles of the power rollers, in other words the speed change ratio, are changed by pistons driving the power rollers in directions perpendicular to the axis of rotation in response to hydraulic pressure. Hydraulic pressure is supplied from a speed change control valve via hydraulic fluid conduits. By providing, for example, orifices in hydraulic fluid conduits so as to exert resistance against movement of the pistons due to external disturbance, the influence exerted by displacement of a particular one of the power rollers due to external disturbance upon the other ones of the power rollers is minimized, and thus the spoiling of the synchronization of the power rollers by vibration is prevented.

Abstract: A hydraulic bearing device includes a cylindrical bearing metal, a groove-like pocket, a dynamic pressure generation land, a fluid flowing space and an oil supply hole. The cylindrical bearing metal supports a rotating shaft. The pocket is formed in an inner peripheral surface of the bearing metal. The pocket defines the dynamic pressure generation land. The fluid flowing space is formed in the dynamic pressure generation land. The oil supply hole supplies fluid from a fluid pressure source to the pocket and the fluid flowing space.The dynamic pressure generation land which has been heated due to fluid friction is cooled by the fluid passing through the fluid flowing space formed in the dynamic pressure generation land. It is thus possible to inhibit thermal expansion of the hydraulic bearing device, especially the dynamic pressure generation land.

Abstract: A chuck (25) for chucking a journal (271) of a crankshaft (27) is attached to the distal end of a main spindle (22) rotated by a drive motor. A phasing rotary shaft (53) is connected to the chuck (25) to rotate about an axis offset from the axis of the main spindle (22). The chuck (25) is provided with a coupling (63) that releasably connects the phasing rotary shaft (53) and the chuck (25). Further, a locking mechanism for locking the phasing rotary shaft (53) is provided. The coupling (63) has a pair of coupling plates (64 and 65) that can be moved closer to and farther from each other. Opposing faces of these coupling plates (64 and 65) have teeth (641 and 651), which are meshed when the coupling plates (64 and 65) are brought close to each other.

Abstract: A silent chain is provided which has reduced elongation based on wear and which is capable of maintaining a high accuracy over a long period of time in use. The inner surfaces of pin holes formed in at least joint trains of plates have been subjected to shaving, and a hard layer of at least one hard metal carbide selected from a group including CrC, TiC, VC and NbC, is formed on the surface of each pin. By shaving the inner surface of each pin hole, the surface pressure applied between the pin hole inner surface and the pin inserted therein becomes lower, whereby the wear of the pin and the pin hole is diminished. Further, since the hard layer on the pin surface is very hard and is chemically stable, the affinity of each plate for the inner surface of each pin hole formed therein is small. Thus, even under the condition of boundary lubrication, it is difficult for adhesion to occur between the pin hole inner surface and the pin inserted therein.

Abstract: The invention concerns a rolling bearing for a release device of a friction clutch. The rolling bearing (1a) includes a rotating outer bearing ring (12) and a rotationally fixed inner bearing ring (2).
