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 chain transmission incorporating a standard roller chain, the diameter of the tooth gap bottom circle of a sprocket in mesh with the chain, is greater than the diameter of the tooth gap bottom circle for a corresponding sprocket having an ISO tooth form.

摘要： In a ratchet type chain tensioner, having a toothed rack on its plunger and a pawl cooperable with the rack, a recess is provided between the front end of the rack and the protruding end of the plunger. In the initial stages of operation of the tensioner, the pawl can enter the recess while permitting the plunger to protrude and retract freely within a limited range. Therafter, when the chain controlled by the tensioner becomes elongated, the pawl cooperates with the rack to limit retraction of the plunger.
