Polygonal action in chain drives
WebPolygonal effect. The chain passes around the sprocket as a series of chordal-links. This action is similar to a non-slipping belt wrapped around a rotating polygon. For smooth operation of chain drives higher number of teeth 19 or 21 gives better life expectancy to the chain with less noise during operation.

WebSep 1, 1987 · The tension in power transmitting chains is subject to periodic fluctuation. This is brought about by factors such as polygonal action, eccentricity of sprockets, etc. A study of the dynamic stability of such a chain is presented. Instabilities due to polygonal action are investigated. The analysis is carried out by treating the chain as a travelling … WebFeb 20, 2004 · The dynamics of continuously variable transmissions (CVT) is characterised by the discrete structure of the chain, which causes the polygonal action. Hence the mechanical model contains each chain link and pulley as a separate body. While a chain link is part of a strand, only joint forces act on the chain links, whereas, in the contact …
