Abstract
A silent chain includes a plurality of inside links each having a pair of teeth and pin apertures and connected to each other by connecting pins inserted into the pin apertures. At least three adjacent connecting pins have a wire extending substantially along the length of a chain. The wire is engaged with the connecting pins in such a way that bending resistance due to elastic deformation of the wire is applied to the chain during articulation of the chain.
Claims20
A power transmission chain comprising:
- a plurality of links, each link having a pair of pin apertures connected to each other by a connecting pin inserted into each of the pin apertures;
- and
- a bending-restraining mechanism comprising a wire extending substantially along a length of the chain and engaging at least three adjacent connecting pins comprising a first outer pin, a second outer pin, and an inner pin located between the first outer pin and the second outer pin;
- wherein the wire is formed such that:
- the wire elastically deforms when an inside link rotates around the inner pin in a first direction from the linearly extending state, the wire thereby applying a bending resistance to the inside link during articulation of the chain.
