STRESS AND STRAIN STATE OF CYCLOID GEAR UNDER DYNAMIC LOADS

Abstract

Besides the large transmission ratio, extremely compact design and high efficiency ratio, cycloid drives are recognizable according to very good working characteristics in dynamic load conditions. Thanks to the simultaneous coupling of almost one third of the number of cycloid gear teeth, cycloid drives can accept large short-term shock loads without any consequences.The most important element of cycloid drive in terms of geometric and kinematic complexity (cycloid gear tooth profile represents equidistant of shortened epitrochoid) as well in relation to the nature of the load on which is exposed, certainly the cycloid gear. This paper analyses the stress-strain state of cycloid gear under real working conditions (in terms of dynamic loads). Observed the different load cases and finite element is determined distribution of strains and stresses on the body cycloid gear.
