The speed of a chain is subject to periodic fluctuations, even for a constant speed of … Webchain when wrapped on a sprocket forms a polygon rather t h a n a circle, is known as polygonal action. One effect of polygonal action is to produce a periodic variation in. the velocity ratio of the drive, and if the frequency of this variation. coincides with a resonant frequency of the system, large stresses m a y. occur.
