摘要： A sprocket of a chain transmission has at least two different pitch angles arranged irregularly in the direction of the circumference of the sprocket's pitch circle. The diameter of the tooth gap bottom circle of the sprocket is larger than the diameter of tooth gap bottom circle of a standard sprocket having the same number of teeth. The teeth are integrally molded as a part of the sprocket by sintering.

摘要： In a silent chain transmission, the distance between the centers of front and rear pin holes of each of the inner link plates of the chain is smaller than the length of the smallest chord obtained by dividing, by the number of sprocket teeth, the circumference of a circle having a radius extending from the center of the sprocket to the center of a pin hole of a link plate of the chain when the last-mentioned link plate is fully engaged with the sprocket.

摘要： In a chain transmission using a hybrid chain having inner and outer links with bushings, or with bushings and rollers, the rollers mesh with a central sprocket, and the link plates have teeth that function as a silent chain, meshing with side sprockets fixed to the central sprocket. The teeth of the link plates of the inner links have a shape different from that of the teeth of the link plates of the outer links. The outer flanks of the teeth can all have the same shape, and the shape difference can be in the shapes of the inner flanks.

摘要： A sprocket for a chain drive using a roller or bushing chain has a plurality of different pitch angles, including both pitch angles larger than the standard pitch angle, and pitch angles smaller than the standard pitch angle. The number of pitch angles in the sprocket larger than the standard pitch angle is greater than the number of pitch angles in the sprocket smaller than the standard pitch angle. The sprocket teeth are integrally molded with the sprocket by sintering.
