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.

摘要： A hybrid chain comprises outer links composed of link plates connected in side-by-side relationship by two connecting pins fitted to holes in the outer plates, and inner links composed of link plates in spaced, side-by-side relationship and connected by two bushings on which rollers are mounted, the bushings being fitted to holes in the inner plates. The inner and outer links are connected in alternating, overlapping, relationship, with each pin of an outer link extending through a bushing of an adjacent overlapping inner link. The chain meshes with a sprocket composed of a central sprocket engaged by the rollers, and two side sprockets. The inner link plates, the outer link plates, or both, have two teeth, with outer flanks in the form of arcs each centered on the more remote pin or bushing hole. The inner link plates, outer link plates, or both, can be double-sided link plates.

摘要： In a chain transmission a standard ISO roller chain meshes with a modified sprocket having a root diameter larger than the root diameter of a standard sprocket designed for use with the standard chain. The angular tooth pitches can be either of two kinds. In a first version, the sprocket has two irregularly distributed tooth pitches, θ−Δθ and θ+2Δθ, there being two tooth pitches θ−Δθ for each tooth pitch θ+2Δθ. In a second version, the sprocket has three angular tooth pitches, θ−Δθ, θ, and θ+Δθ, in equal numbers, also distributed irregularly.

摘要： In a roller chain transmission, the chain has rollers which are tapered from a central region toward their ends, and the teeth of the sprockets in driving and driven relationship with the chain have concave surfaces that contact the tapered parts of the rollers on both sides of a central region. However, there is no contact between the rollers and the sprockets in the central region. The central regions of the rollers can be provided with compressible external resin rings that cushion the impact on engagement of a roller with a sprocket tooth. Alternatively, each roller of the chain can be formed of two separate parts, and a compressible resin ring can be disposed between the two parts and enveloped by the two parts and a bushing surrounded by the roller parts

摘要： In a chain transmission, the link plates of a roller chain or rollerless bushing chain are formed with pairs of teeth. A sprocket has a central set of sprocket teeth for meshing with the rollers or bushings, and sets of side sprocket teeth for meshing with the teeth of the link plates. The teeth of the link plates function as a silent chain. After an inner flank of a link plate tooth comes into contact with a side sprocket tooth, a roller and an outer flank of the link plate tooth are seated on the sprocket.
