摘要： A variable diameter pulley according to the present invention has a pair of pulley bodies each axially movably fitted around a rotation shaft. A power transmission ring is held between power transmission surfaces formed in a tapered shape on opposed surfaces of the pair of pulley bodies. A belt is engaged with the outer circumference of the power transmission ring. The power transmission ring is movable eccentrically with respect to an axis of the pulley bodies. The pulley bodies are biased toward each other by a belleville spring. The belleville spring couples the pulley bodies to each other for power transmission. A torque is transmitted between the belt and the rotation shaft through the power transmission ring, the pulley bodies, the belleville spring and a coupling member.

摘要： A variable diameter pulley comprises a pair of pulley main bodies (18, 19) connected to a rotating shaft (15), and a power transmission ring (20) interposed between the pulley main bodies. A belt (2) is passed around an outer periphery of the power transmission ring (20). The power transmission ring (20) is made eccentric relative to an axis (15a) of the rotating shaft (15) so as to be varied in its contact diameter (D). Both pulley main bodies (18, 19) are threadedly connected to the rotating shaft (15) by a torque cam mechanism (T) composed of a pair of thread connection mechanisms, which are inversely threaded to each other. Torque for effecting rotation of the respective pulley main bodies (18, 19) relative to the rotating shaft (15) is converted into a force, which causes both pulley main bodies (18, 19) to approach each other in equal amounts of stroke.

摘要： A continuously variable transmission including discs made of heat-resisting bearing steel, and rollers made of ceramics. The heat-resisting bearing steel contains 0.8-1.5 wt % of C, 0.5-2.0 wt % of Si, 0.3-2.0 wt % of Mn, 1.3-1.98 wt % of Cr, and 0.3-1.0 wt % of Mo, (Si+Mo) being 1.0 wt % or more. Because the rollers are made of ceramics superior in heat resistance, the toroidal type continuously variable transmission, even if used under high load and high rotational speed, is free from occurrence of sticking between discs and rollers and damage of the raceway surfaces.

摘要： A tip for a cutting tool which can apply a heavy residual stress in compression to a material to be cut. This tip has four cutting portions. Each of the cutting portions has first and second rake surfaces having first and second angles of negative values, respectively, relative to an upper surface of the tip. Absolute value of the first negative angle is smaller than that of the second negative angle. The second rake surface is located further from a center of the tip than is the first rake surface, and is also located behind the first rake surface relative to a cutting direction of the tip.

摘要： A hydraulic transmission coupling apparatus which is used instead of a center differential or a viscous coupling being usually mounted between a front wheel drive shaft and a rear wheel drive shaft of a four-wheel drive vehicle, and transmits driving force existing between the two shafts. The hydraulic transmission coupling apparatus is provided with a vane-type hydraulic pump which generates hydraulic pressure corresponding to a relative rotation speed difference of the two drive shafts and a variable throttle valve being disposed in the passage connecting a discharge port of the hydraulic pump with a tank, whose opening area varies according to the hydraulic pressure generated by the hydraulic pump, thereby driving force to be transmitted being increased or decreased steeply as the rotation speed difference becomes larger.
