eccentric rod वाक्य

Three sets of Walschaerts valve gear were used, the one for the inside cylinder being mainly located inside the frame, but driven from the same eccentric crank as the valve gear on the left-hand side; two eccentric rods of different lengths being attached to the same crank.
In order to do so an eccentric usually has a groove at its circumference around which is closely fitted a circular collar ( " eccentric strap " ) attached to which an " eccentric rod " is suspended in such a way that its other end can impart the required reciprocating motion.
