Title: Method for chain drive and chain

Abstract: Method for chain drive, whereby the chain, such as a transmission chain, conveyor chain and/or like, is formed of several shaped pieces (1), that are connected to each other one after another at jointing points (N) by means of joint pins, and that is being driven by means of a wheel arrangement, that includes at least one chain wheel (7), such as a drive wheel, a turning wheel or the like. Particularly wearing of the chain, that is due to bending of the chain essentially along the longitudinal direction (p) of the joint pins, is being minimized by taking advantage of joint pins (x), the cross section of which changes in the longitudinal direction (p). The invention also relates to chain functioning according to the method.
