齿厚偏差和中心距偏差是空回计算的基础。本文对齿厚偏差引起的空回误差,分析其侧隙范围内的运动过程,是相应于行星轮与系杆暂时固结共同统内齿轮中心转动来完成的,其空回计算可按一般办法折算到分度圆切向上进行。对中心距偏差引起的空回误差,本文先分析其在一般外啮合付中的计算公式,再分析少齿差行星传动中的计算公式;在这一侧隙范围内的运动,则是相应于系杆的转动以及行星轮随同系杆端点作平动来完成的。
Tooth thickness deviation and center distance deviation is the basis of the empty back calculation. In this paper, the error of backlash caused by tooth thickness error is analyzed. The analysis of the movement process in the range of backlash corresponds to the temporary consolidation of the planetary gear and the tie rod. The calculation of the backlash can be done according to the general method Converted to sub-degree round cut up. In this paper, we first analyze the calculation formula of the error in the backlash caused by the deviation of the center distance, and then analyze the formula in the less tooth difference planetary transmission. The movement in this backlash range corresponds to The rotation of the tie rods and the planet wheels are done in translation with the ends of the tie rods.
