Question
Download Solution PDFStatement I): In chain drives, the angle of articulation through which link rotates during engagement and disengagement is greater for a small number of teeth.
Statement II): The greater angle of articulation will increase the life of the chain.Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe angle of articulation is given by \(\frac{{360^\circ }}{{\rm{N}}}\) where N is equal to the number of teeth on the sprocket. So, for a small number of teeth the angle of articulation increases. Hence statement I) is true.
Now, for greater life of chain, the angle of articulation should be reduced to minimize the wear of chain and fatigue of rollers. So, statement II) is incorrect.Last updated on Jun 23, 2025
