AI Technical Summary
Technical Problem
[0003]现有技术中，常规传动结构多采用单一轴承配置(如深沟球轴承或圆柱滚子轴承)，在承受复合载荷时存在显著局限性：平面轴承虽能承担轴向推力，但缺乏径向支撑能力；角接触球轴承虽可兼顾径向与轴向载荷，但在高频次启停工况下易发生轴向游隙增大现象
Benefits of technology
[0017]本实用新型的有益效果是：本实用新型采用模块化设计，所述第一连接组件起到连接外部驱动部件和推进组件的作用，同时给所述平面轴承和所述斜珠轴承起到支撑和限位的作用，所述平面轴承起到承受推进组件的轴向载荷(推力方向)，所述斜珠轴承起到承受径向载荷(如旋转时的离心力)和部分轴向载荷，分担所述平面轴承承受的的轴向力，所述推进组件是核心的传动部件，负责将外部驱动部件输出的推力转换为稳定、线性的驱动推力，所述第二连接组件起到连接推进组件和外部执行部件的作用，所述第一连接组件和所述第二连接组件分别给所述推动组件的两端起到支撑和连接的作用，本实用新型整体设计旨在增强该装置的稳定性、降低摩擦损耗，并延长机械寿命。
