新型并联复式活齿传动原理及其啮合特性
New Parallel Compound Movable Tooth Transmission Principle and Its Meshing Characteristics
摘要
Abstract
The transmission ratio of single-stage movable tooth transmissions was relatively low,while the series-connected movable tooth transmission structure was lack of compactness and inability to achieve power splitting transmission.Therefore,a novel parallel compound movable tooth transmission de-vice was proposed,which comprised of a primary planetary gear transmission and a planar steel ball mov-able tooth transmission.The operating principles and structures of this device were introduced,along with the tooth number calculation method.The profile equations of the double-circular-arc tooth profiles were derived,and the analysis of the meshing characteristics was conducted.The results show that this innova-tive transmission device features a compact structure,enabling a high transmission ratio.By adjusting the number of teeth,the device achieves both forward and reverse output rotation,power splitting transmis-sion,and"concave-convex"tooth contact.It exhibits high load-bearing capacity and is suitable for applica-tions requiring large transmission ratios and high power density.关键词
