摘要： PURPOSE: A preload fixing apparatus of an orbital friction driving mechanism is provided to reduce noise and backlash by transmitting power from the input shaft to the output shaft without passing the gear train, to improve power transmission efficiency by restricting slip between the inner periphery of the ring roller and the outer periphery of the orbital roller with applying preload, and to prevent wear from friction by forming the lubrication film with injecting lubricant. CONSTITUTION: An orbital friction driving mechanism comprises a body casing(10) having a space part; an input shaft(20) inserted to the body casing; a sun roller(30) combined with the input shaft in the space part; a ring roller(40) mounted outside the sun roller in the space part; plural orbital rollers(50) rolled and contacted to the outer periphery of the sun roller and the inner periphery of the ring roller with revolving and rotating; and an output shaft(60) inserted to the body casing and extended in the same axis of the input shaft to rotate in revolving the orbital roller. The ring roller is divided into a right separation body having a fixing part fastened in the body casing and a roller part covering the right of the roller groove, and a left separation body having an assembling part and a roller part covering the left of the roller groove. A preload bolt combines the assembling part of the left separation body with the fixing part of the right separation body.
摘要翻译：目的：提供一种轨道摩擦驱动机构的预载固定装置，通过在不通过齿轮系的情况下将动力从输入轴传递到输出轴，以减小噪音和间隙，通过限制滑轮的内周边之间的滑动来提高动力传递效率环形辊和轨道滚子的外周边施加预载荷，并通过用注入润滑剂形成润滑膜来防止摩擦磨损。构成：轨道摩擦驱动机构包括具有空间部分的主体壳体（10）插入到所述主体壳体中的输入轴（20）与空间部分中的输入轴组合的太阳辊（30）; 安装在太阳辊外部的空间部分中的环形滚轮（40）多个轨道滚子（50）旋转并旋转而卷绕并接触太阳辊的外周和环形滚筒的内周; 以及输入轴（60），其插入到主体壳体中并且在输入轴的同一轴线上延伸以在旋转滚动辊中旋转。环形滚筒分为具有紧固在主体壳体中的固定部分和覆盖滚子槽右侧的滚子部分的右侧分离体，以及具有组装部分和覆盖辊子左侧的滚子部分的左侧分离体槽。预紧螺栓将左分离体的组装部分与右分离体的固定部分组合。
