Finite Element Analysis of the Oldham Coupling by using ANSYS

Proper alignment for a rotating shaft has been identified long ago as a precondition to safe and trustworthy uses. High noise levels, frequently vibrating device, failure of bearings and lubrication are the types of machine rupture that are the results of the shaft misalignment. To get the sufficient torque and efficient power transfer, proper alignment plays a crucial role. Oldham coupling is one of the couplings which is properly aligned and transfers the power to one another shaft without any physical joint. One of the major advantages of Oldham coupling is that it can use for shafts which are non-coaxial. In this work, a simulation model set up is constructed in a CATIA for a driver and a driven shaft which are connected with each other by Oldham coupling. Proper shaft alignment is done with the help of Oldham coupling alignment and performance readings of ANSYS are leading us to the understanding the efficiency of the power transmission. The objective of this work is to study the performance of the Oldham Coupling using CATIA and ANSYS. In this manner, finite element analysis was performed. It was found that the simulation of Oldham Coupling is too time consuming to be used in everyday engineering work. However, Oldham Coupling can successfully be predicted with simplified models.
