AI Technical Summary
Technical Problem
[0003]因此，本发明提供一种RV减速器、用于RV减速器的调节装置及机器人，能够解决现有技术中更换减速器零件，重复装配并测试轴承预紧量的措施调整，过程繁琐，且调节精度不易控制的技术问题
Benefits of technology
[0019]本发明通过控制支撑柱绕自身轴线转动调整位于行星架和刚性盘之间的部分的长度，提高了调整第一内圈圈和第二内圈之间的轴向距离，比现有技术需要将RV减速器的轴承拆下进行更换更加快捷方便；由于无需将两个轴承的外圈从针齿壳上拆下，避免了两个轴承出现较大的同轴度误差，提高了两个轴承的同轴度，有利于提高RV减速器的工作精度。
