摘要： A silent chain, as well as a rocker pin and a plate of the silent chain, are provided which are capable of enhancing the transmission efficiency, and improving the fatigue strength of the plate to thereby prolong the service life of the silent chain. Rocker pins are inserted into the pin holes of each plate of a plurality of plates of a silent chain. The rocker pins are located closer to outer ends of the plate and are formed with generally flat plate abutting surfaces. The plate abutting surfaces are received by generally flat pin seating surfaces of the pin holes, respectively, to surely prevent rotation of the rocker pins relative to the pin holes. Further, in addition to the generally flat pin seating surfaces, generally flat and short continuous surfaces are formed centrally up and down of each pin hole. Thus, stress concentration on the plate is diminished and the fatigue strength of the plate is improved.

摘要： A plate for a silent chain has a side punched into a forked shape for engagement with a sprocket. The forked side of the plate has inner engaging surfaces opposing each other, outer engaging surfaces, and an arcuate leg-side end surface connecting the inner engaging surfaces. The leg-side end surface, on which stress is likely to be concentrated, has a shear face tissue along at least 70% of the thickness of the plate. A silent chain having such a plate has a high plate fatigue strength and enhanced durability and reliability, and can be manufactured at a low cost.

摘要： A frictional transmission chain drive for use between V-groove pulleys comprises a series of C-shaped chain struts and friction force struts superposed along the length of an endless transmission chain. The chain struts are fitted in grooves located across link plates of the chain, with their open ends alternately located on opposite sides of the transmission chain. The friction force struts are provided with recesses which grip the chain to prevent sideways movement of the struts relative to the chain. The friction force struts on opposite sides of a chain strut can have their open ends on the same said of the chain as the open end of the chain strut, or, alternatively, can have their open ends on the side of the chain opposite the side on which the open end of the chain strut is located.

摘要： A silent chain having a series of links, with adjacent links being pivotally joined by transversely-extending connecting pins. Each link is defined by a plurality of link plates disposed in sidewardly adjacent relationship, which link plates define inwardly projecting sprocket teeth adjacent opposite ends thereof. Guide plates are disposed adjacent opposite sides of some of the links and extend between adjacent connecting pins. Plate spring links are sidewardly interposed between adjacent link plates or between a link plate and a sidewardly adjacent guide plate. The spring link plates have a configuration such that no portion thereof extends into the pitch circle of the sprocket which meshes with the chain links.

摘要： In a method and apparatus for press bending a metal plate, a punch is inserted into a recess of a die to bend a plate. The punch has a first edge formed away from a die and a second edge formed near the die. A corner of the recess of the die opposed to the punch is chamfered. The chamfered face has a third edge formed at the border of the top side of the die at the chamfered recess. In a first half of the press bending, the plate is bent with the first and third edges serving as lines of contact. Subsequently, the plate is further bent with the second edge serving as a line of contact. A portion of the punch between the first and second edges is held in a non-contact state with the plate throughout steps of press bending the plate.

摘要： An improved friction drive chain especially for a continuously variable transmission has a plurality of friction plates, each of the friction plates being substantially I-shaped in lateral section. The friction plates are arranged adjacent one another and connected by connecting link elements received in recesses formed in both lateral sides of the friction plates between upper and lower beam members of said friction plates. The connecting link elements are laterally grooved to bear longitudinally against the friction plates. The outer surfaces of the lower beam members of the plates define friction drive surfaces for contact with driving and/or driven pulleys. The friction plates are heat treated to increase strength, for example by quenching and annealing. The friction drive surfaces are formed with hardened layers by surface hardening treatment such as by electron beam or laser.

摘要： The invention relates to apparatus and methods for manufacturing a bent product by press bending a malleable material. The bent product is bent along the lengthwise axis and has a bottom wall and at least one sidewall in cross section. The apparatus preferably includes a die having within its surface a recess. The recess is bent along the lengthwise axis. The apparatus also includes a punch that may be inserted into the recess of the die. The die and the punch substantially correspond to each other such that the die and the punch include a first portion having a first bend radius corresponding to a lengthwise bend in the bent product and a second portion having a second bend radius corresponding to a linear region of the bend product. If the first bend radius is smaller than the second bend radius, chamfered faces formed in the die and punch are shallower and narrower in the first bend radius than the second bend radius. This relationship permits the folding of the material within the lengthwise bend region to be completed before the folding of the material by the die and punch regions having the larger bend radius.
