摘要： In a timing chain drive unit the tooth pitch of a driven sprocket from which a tension span of the chain travels toward a driving sprocket varies cyclically around the circumference of the driven sprocket and cyclically increases and decreases the length of the tension span in synchronism with load variations imparted to the driven sprocket by a valve-operating camshaft.

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.

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.
