摘要:

单级活齿传动的传动比较小,而串联式活齿传动结构不紧凑且无法实现功率分流传动,为此,提出一种由一级行星齿轮传动和一级平面钢球活齿传动构成的新型并联复式活齿传动装置。介绍了该装置的传动原理及结构,给出了配齿计算方法,推导了双圆弧活齿啮合副齿廓方程,对其啮合特性进行了分析。研究结果表明,该新型传动装置结构紧凑,可获得大传动比,能通过齿数调整实现正反向输出,实现了功率分流传动和“凹-凸”齿接触,具有较高的承载能力,可应用于有大传动比和高功率密度要求的场合。

关键词: 并联复式活齿传动, 功率分流, 齿廓方程, 接触分析

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 device was proposed, which comprised of a primary planetary gear transmission and a planar steel ball movable 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 innovative 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 transmission, and “concave-convex” tooth contact. It exhibits high load-bearing capacity and is suitable for applications requiring large transmission ratios and high power density.

Key words: parallel compound movable tooth transmission, power splitting, tooth profile equation, contact analysis
