行星变速箱机构性能和结构特征的评价指标分析

Analysis on evaluation index for mechanism performance and structural features of planetary gearbox

行星变速箱广泛应用于各种车辆的传动系中。为获得结构合理、紧凑、性能好、可靠的传动装置 ,组成行星变速箱的行星机构应有多个评价指标。主要研究这种机构的运动学指标、性能指标和结构特征指标 ,并剖析其内在关系 ,为设计时的合理选择提供理论和技术依据。

Planetary gearbox has widely been applied to the transmission system of various kinds of vehicles. In order to obtain a reasonable structured, compact, good functioned and reliable transmission device, the planetary mechanism, which constitutes planetary gearbox, ought to have plenty of evaluation indexes. Kinematics index, performance index and structural feature index of this mechanism have mainly been studied in this paper, and their inherent relationship was dissected, thus the theory and technical bases were provided to the reasonable selection while making the design.
