Polygonal action in chain drives
Did you know?
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. WebDec 1, 2013 · Abstract. Roller chain drive is widely used in timing mechanism of gasoline engine. However, its polygonal action and meshing impact effect resulted from the non-conjugated meshing feature may ...
