在文献[1]中介绍了二齿差摆线针轮行星传动的原理和几何计算,本文介绍强度计算,有关符号的意义同文献[1]。针轮与摆线轮在啮合传动中是多齿啮合,摆线轮与针齿之间,以及W机构中柱销套与柱销孔之间的载荷分布很复杂,除了受接触变形影响外,还受制造误差、侧隙和被柱销孔削弱的摆线轮体变形的影响。为了便于研究,作以下的假设:1.装配间隙为零;2.摆线轮、针齿壳和转臂的变形忽略不计;3.不考虑摩擦的影响。设图1中摆线轮沿顺时针方向转动,由于在摆线针轮行星传动中,转臂的转向与摆线轮的相反,因此在转化机构中针轮的转向与摆线轮的相同,并可认为针轮为主动。所以,在y轴右面,针轮与摆线轮间有离开的趋势,它们之间没有作用力存在;在y轴左面,针齿与摆线轮相啮合的部分,相互间有作用力和反作用力存在。
In [1], the principle and geometrical calculation of planetary gear transmission with two-tooth decentered cycloid are introduced. The calculation of strength is introduced in this paper. The meanings of the symbols are the same as those in [1]. The pin wheel and the cycloidal wheel are multi-tooth meshing in the meshing transmission. The load distribution between the pin wheel and the pin teeth and between the pin sleeve and the pin hole in the W mechanism is very complicated. In addition to being affected by the contact deformation, It is also affected by manufacturing errors, backlash, and deformation of the cycloidal body that is weakened by the pin bore. In order to facilitate the study, the following assumptions are made: 1. The assembly clearance is zero; 2. The deformation of the cycloidal gear, pin gear housing and boom is neglected. 3. The effect of friction is ignored. In Figure 1, the cycloidal wheel rotates in the clockwise direction. Due to the reverse rotation of the rotating arm and the cycloidal wheel in the planetary gear of the cycloid wheel, the steering of the pin wheel in the conversion mechanism is the same as that of the cycloidal wheel, And think that the pin wheel is active. Therefore, on the right of the y-axis, there is a tendency for the pin wheel and the cycloid wheel to move away from each other with no force between them; on the left of the y-axis, the pin teeth mesh with the cycloid wheel and exert a force and reaction against each other Power exists.
