Experimental Investigation on wear behaviour of Polymer based Spur Gears – A Review

Abstract

Polymer gears are being used in many engineering applications because of their low weight, low cost, self-lubrication capability and mass manufacturing possibility. With the continuous evolvement of science and technology the use of polymer gears is increasing in all the upcoming industries. The performance of the polymer gears will be obtained by conducting the thermal and wear behaviour under different loads and speeds. Investigates the potential of three different thermoplastic materials such as Polyamide (PA66), Polyether ether ketone (PEEK) and Polyoxymethylene (POM) are to be used in plastic gearing applications. The gears are manufactured by gear hobbing process, steady state analysis of the gears will be carried out at a torque of 1.4 Nm and a rotational speed of 900 rpm to measure the reduction in the gear tooth, durability and failure modes occurring in the gears.
