STRESS REDUCTION BY INTRODUCING STRESS RELIEVING FEATURES OF SPUR GEAR USED IN LATHE HEADSTOCK
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 4, Issue 8
Abstract
This paper deals with the reduction of contact stresses of the spur gear and pinion used in headstock of a lathe machine by introducing stress relieving feature of different shapes i.e. circular hole, elliptical hole and aero fin hole. In this paper the stress analysis of mating gears of the spur gear with three different materials is done to determine the contact stresses generated in the gear teeth. In the previous paper the results obtained from Finite Element Analysis (FEA) using Ansys are compared with the values obtained from theoretical Hertzian equation. The materials of spur gear used for analysis are grey cast iron, high carbon steel and medium carbon steel. In this paper the stresses which were calculated has been reduced by introducing stress relieving feature of different shapes. It was found that Stress relieving feature having the shape of aero- fin yielded better results when compared to elliptical and circular holes.
