Coupling Mechanism

INTRODUCTION

A Oldham coupling is an example of an inversion of the double slider-crank chain.
This type of coupling is used to connect two parallel shafts which are not co-axial.
The flanged ends of the shafts have diametrical grooves and the intermediate disc has a tongue diametrically across each of its faces, both keys being at right angles. These tongues fit into the grooves in the shaft flanges and the intermediate disc then transmits rotation from the input to the output shaft with uniform angular velocity.
The Coupling Mechanism, “MAC”, has been designed to study an Oldham coupling and its operation when the input and output shafts are laterally displaced.

EXERCISES AND PRACTICAL POSSIBILITIES

1. Study of an Oldham mechanism
2. Demonstration of the action of an Oldham coupling when the input and output shafts are laterally displaced.
3. Demonstration of the angular velocity conservation in a misaligned transmission shaft.
