Mesh contact impact analysis of involute beveloid gear

Abstract

Abstract: Based on the elastic contact dynamics theory and the physical model of gear transmission, the mesh impact problem of involute variable-thickness gears is analyzed, and the full tooth mesh contact impact model of variable-thickness gears is established; by simulating the gear mesh contact state, the gear mesh area is discussed, and the contact collision analysis is carried out by using LS-DYNA software to study the impact force and impact stress with speed and impact position respectively. The results show that the speed and impact position have a significant influence on the impact force. The results show that the rotational speed and impact position have a great influence on the impact force and impact stress, and the maximum impact stress is mainly concentrated near the top of the tooth and the large and small ends of the gear teeth; the larger the rotational speed is, the greater the difference in impact stress between the loaded and unloaded surfaces of the gear teeth.

Key words: involute beveloid gear, meshing impact, contact analysis, impact stress
