Abstract

Meshing stiffness is an important factor used in modelling of gear transmission errors (TE) and wear, as load sharing has to be taken into account. However, as far as the authors are aware, there is no published information that can be used to calculate tooth stiffness for a particular worm gear pair. This paper presents a method for calculating worm gear meshmg stiffness based on experimental measurements. The resulting stiffness value compare reasonably well with the estimations htherto made by analogy with spurlhelical gears. 1 Introduction Worm gears are widely used in various industrial and every day life applications because of their compactness, high precision, smoothness in operation. However, worm gears efficiency and wear resistance are normally lower than these of other types of gears of similar size, due to high sliding inhere
