Design and analysis of internal gear drive with arc contact path
摘要
Abstract
A high contact ratio internal gear drive with arc contact path was proposed for internal gear transmission. The circular arc connecting the intersection point of addendum circles and the intersection point of pitch circles was chosen as the path of contact. The addendum tooth profiles of pinion and internal gear conjugated with each other were constructed based on the given path of contact. According to gearing theory, the dedendum tooth profile was designed as conjugate curve of the addendum tooth profile of the mating gear and modification of dedendum tooth profile to internal gear was carried out. Geometric properties analysis and loaded contact analysis of the novel internal gear were also carried out. The results show that undercutting and addendum interference do not occur for the novel internal gear. The novel internal gear drive has higher contact ratio, smaller sliding ratio, but bigger induced curvature compared with the involute internal gear drive. The stress, especially the bending stress of the novel high contact ratio internal gear drive decreases remarkably. The novel high contact ratio internal gear with tooth number of 38/53 has 7 tooth being in meshing, which confirms the high contact ratio for the novel internal gear drive.关键词
