Generalized Oldham Coupling of Turning Block Double Circular-Arc-Slider Mechanism

概要

This paper deals with a new mechanism, the generalized Oldham coupling. First the existence of the mechanism is deduced through the inversion of chain. This is a turning block double-slider mechanism with circular-arc-sliders and is a cyclical varying speed coupling. Next the relative angular motion between two shafts connected by the coupling is analysed and is verified experimentally. This coupling has one to one correspondence to the double crank mechanism on the condition that two mechanisms yield the same angular motion. In particular, the coupling corresponding to that having one crank of infinite length generates a new motion. The Oldham coupling corresponds to one of that having both cranks infinite length and is considered to be a special case of the generalized Oldham coupling.
