Influence of addendum modification on spur gears stability

Abstract

The aim of the presented research is to develop the new method for studying the influence of main characteristics of spur gears on their stability behaviour. Few different processes and calculations are compiled in algorithm make a method for spur gears stability analysis. In this paper, the main influence factors for spur gears stability are identified and the discussion of appropriate dynamic model of spur gears is given. In order to determine the time-dependent load distribution and mesh stiffness, developed procedure uses verified spur gears model for finite element analysis. The special attention has been devoted to the research and conclusions about the influence of addendum modification on spur gears low-vibration and stability. The discussion is based on comparative study of a series of gear pairs with different addendum modification coefficient in order to select the optimal tooth profile design with gear pair low-vibration and stability as the main aspects.
