本文提出的各种行星轮系啮合效率计算的统一公式不仅适用于常用的2K-H、K-H-V型,也可用以计算一般效率公式无法计算的2K-V型及过去必须用功率流法计算的封闭差动轮系、方法便于掌握。本文建议3k型轮系应以大内齿轮固定,小外齿轮放在大内齿轮同一排的最合理结构,不仅在传动比、效率、强度以及外形尺寸方面都好,而且在效率计算时,也可拆成两个串联的2K-H型,从而可用一般的效率公式计算效率,理论上合理.方法上简单可行。
The formulas for calculating the meshing efficiency of various planetary gear trains presented in this paper are not only applicable to the commonly used 2K-H and KHV models, but also to the 2K-V model which can not be calculated by the general efficiency formula and the closed model which must be calculated by the power flow method in the past Differential gear, easy to grasp the method. This paper suggests that the 3k-type gear train should be fixed with a large internal gear. The most reasonable structure of the small external gear on the same row of internal gear is not only good in transmission ratio, efficiency, strength and size, but also in the efficiency calculation Can be disassembled into two series 2K-H type, which can be used to calculate the efficiency of the general efficiency formula, in theory, reasonable method is simple and feasible.
