Performance of injection moulded carbon nano tube polypropylene asymmetric gears

Abstract

Polymer composite gears are being utilized in many engineering applications due to their light weight, self-lubrication, cost effectiveness, and mass production capabilities. However, thermal sensitive mechanical properties of the polymers limit their extended usage. During service, polymer gears generate heat caused by repetitive tooth surface interaction and material hysteresis. In this work, an attempt was made to investigate the potential of using air cooling, asymmetric tooth profile and ca newline
