摘要： A pulley comprises a disk and an insert. The insert is fitted into the center of the disk integrally. Linear expansion coefficient of the disk is larger than the same of the insert. A concavity is formed on a periphery surface of the insert so that both side surfaces of the concavity are slanted outwardly, i.e. a distance between the side surfaces become large in proportion to being far from the centerline of the insert. When a slanting angle is defined as an angle between the side surface and a line which is perpendicular to the centerline of the insert on a plane including the centerline of the insert, the slanting angle is set from ten degrees to forty-five degrees, preferably from fifteen degrees to forty-five degrees. The disk is made of synthetic resin such as phenol resin, and the insert is made of metal such as iron.

摘要： A method for installing a cushion ring on a sprocket body to construct a sprocket assembly includes applying a deforming force to a cushion ring so that an opening therein is deformed to a shape that accommodate passage of a non-circular flange of a sprocket body therethrough. When the cushion ring is deformed, the non-circular flange of the sprocket body is inserted through the opening of the cushion ring. The deforming force is then released from the cushion ring so that the cushion ring is trapped between the flange and another portion of the sprocket body. The sprocket assembly includes at least one and typically two cushion rings trapped by respective non-circular flanges.

摘要： A double-meshing-type silent chain of a silent chain drive includes link plates having the identical side profile. Each link plate has two meshing teeth and a flat back face formed opposite to the meshing teeth. Two kinds of links are alternately arranged in the longitudinal direction of the chain, while the adjacent links are connected by pins. In one kind of link, an odd number of the link plates are disposed in the width direction of the chain. In the other kind of link, an even number of the link plates are disposed in the width direction of the chain. In each link, the link plates are oriented such that the meshing teeth of link plates located at widthwise opposite ends project outwardly with respect to the chain and the meshing teeth of the remaining link plates project inwardly with respect to the chain. Various types of sprockets used for meshing with the double-meshing-type silent chain are also disclosed.

摘要： A gear wheel includes multiple helical toothings, each having a different helical angle. A pressing method for molding a gear wheel involves introducing a compactable material into a chamber of a pressing tool, compacting the material, exposing the helical toothings of the gear wheel, and removing the molded body from the pressing tool. A pressing tool for pressing, as one part, a gear wheel, includes a matrix, cylindrical first and second molding tool parts which can be translated along and then rotated about a longitudinal axis, and a driver coupled to the molding tool parts or driving them. The molding tool parts can be moved towards and away from each other and the inner surface of the matrix delimits the chamber and is shaped to allow a linear axial sliding movement of the compactable material relative to the matrix.

摘要： A sprocket includes a hub and a plurality of teeth projecting radially outwardly from the hub. At least one cushion ring is located adjacent the teeth, and the cushion ring defines a plurality of compression pads separated from each other by transverse grooves. Each of the compression pads is defined symmetrically about a circumferential mid-point. When part of a sprocket with symmetric tooth spaces, the cushion ring is being operable identically in first and second opposite rotational directions. In one arrangement, the compression pads each include a planar outer surface having a leading and a trailing end, wherein the leading end and trailing end are located a common radial distance from a center of the hub about which the sprocket rotates. The tooth spaces of the sprocket can be symmetric, asymmetric and the root surface can be relieved. The sprocket can include multiple tooth profiles distributed randomly about the hub.

摘要： A power transmission device for suppressing oxidation and degradation of dampers for improved damper life has dampers with contact surfaces for making contact with a pulley inner periphery and a hub outer periphery, and non-contact surfaces out of contact with the pulley inner periphery and the hub outer periphery. The non-contact surfaces have oxygen permeance suppression layers made of, for example, acrylic rubber, having an oxygen permeability less than that of the contact surfaces. Consequently, it is possible to suppress the permeance of oxygen into the dampers through the oxygen permeance suppression layers. Thus, even when the dampers rise in temperature, the outer peripheries thereof exposed directly to the air can be prevented from oxidizing and degradation.
