摘要： A sliding spline shaft device of the present invention includes a male spline and a female spline that is fitted to the male spline in an axially slidable manner, and at least one of the splines has a surface processed layer. The surface processed layer includes an undercoat layer, an intermediate layer containing phosphate, and a topcoat layer containing solid lubricant, in this order. The undercoat layer contains iron nitride and/or iron carbide. Thus, the surface of a base material has high hardness. As a result, microscopic deformation of the sliding surface is reduced, and increase in a real contact area is suppressed, whereby stick-slip is prevented.

摘要： In a power transmission apparatus, a centrifugal clutch includes a holder, a press, and springs to urge masses from a radially outer position to a radially inner position. The masses are each housed in an associated one of housing portions arranged in a circumferential direction of the holder such that the masses are radially movable. More than one spring is provided in the circumferential direction between an inner peripheral wall surface of each of the housing portions and an associated one of the masses to urge the associated mass from the radially outer position to the radially inner position.

摘要： Provided is a method of machining a sealing surface, the method being capable of finishing a sealing surface at low cost and in a short period of time, eliminating lead marks, and forming the sealing surface highly accurately. The method of machining a sealing surface comprises finishing a sealing surface (M), which is to be machined, by cutting the sealing surface (M) using a rotating cutting tool (81) while rotating a workpiece having the sealing surface (M) about an axis thereof. The cutting of the sealing surface (M) using the rotating cutting tool (81) comprises hardened steel cutting which generates no lead marks.

摘要： A clutch assembly for transmitting power from an output shaft of an engine to an input shaft of a gearbox includes annular friction surfaces on at least one of the flywheel and the pressure plate. The annular friction surface has a plurality of grooves that extend across the annular friction surface away from an inner rim of the friction surface toward an outer rim of the friction surface to prevent a reduction in friction caused by outgassing or abraded particles trapped between engaging friction surfaces.

摘要： In a locking type reverse input blocking clutch, smooth finished surfaces having no directionality are formed, by barrel polishing, on surfaces brought into contact with rollers while rotation is being transmitted from the input side to the output side, i.e. an inner peripheral cylindrical surface of an outer ring and a surface of a lid portion opposed to the rollers. With this arrangement, it is possible to reduce the sliding resistance between the rollers and the outer ring and between the rollers and the lid portion, without the need to reduce the forces of springs for pushing the rollers into narrow portions of wedge-shaped spaces. This in turn makes it possible to reduce the torque necessary to transmit rotation from the input side to the output side, while maintaining high locking performance.

摘要： A synchronizer ring (10) for synchronized manual transmissions is manufactured by forming or reshaping a flat material of metal, wherein a conical friction surface (20) is produced, into which axial grooves (24) are incorporated by chipless machining, wherein a tool is axially shifted relative to the friction surface (20) to produce the final friction surface (20). At least the friction surface (20) is vibration-ground and subsequently hardened.

摘要： In a dry friction material and a method for manufacturing the same, to maintain a content of glass fibers low on a whole dry friction material to apply a hole boring for caulking assembly with high strength and high stiffness at a part to be subjected to the hole boring.A part (glass-rich part 30) to be subjected to the hole boring is pressed at a higher pressure than a part not to be subjected to the hole boring in a press-shaping step by providing a rib 21 protruding toward a shaped body side on a part of press dies 20A, 20B corresponding to the part to be subjected to the hole boring. Thereby, only a compounded rubber 4 is pushed outward and only the glass-rich part 30 has an increase in a content of glass fibers 3. Thereby, strength that can withstand the hole boring is obtained. Accordingly, a dry friction material 1 with a bored hole 2 bored without generating a failure in the hole boring can be manufactured.

摘要： A dog clutch that transmits driving force from a driving-side rotating body to a driven-side rotating body. In the bottom face of recessed parts formed in the driving-side rotating body there is a strip-shaped island part protruding from the bottom face in the circumferential direction, and there are groove parts between the island part and torque-receiving surfaces. The groove parts and the bottom face are formed by a forging mold, and their surfaces are forged mill scale. The island parts have a cut surface, which is formed by cutting the top part of the islands after they have been formed by the forging mold, and which receives the tip surface of a protruding part. The groove parts are formed so as to be deeper than the bottom face, and the cut surface is formed as to be shallower than the bottom face.
