    摘要:

    RV(Rotor Vector)减速器是一种工业机器人关节高精密减速传动装置,通常由第一级渐开线行星传动机构和第二级摆线针轮传动机构组成。该研究工作基于针齿理论受力模型,参照针齿的实际磨损情况,对传统针齿受力分析方法进行了改进。通过改进方法分析发现针齿上存在明显的剪切力和弯曲应力分布,为了消除相关应力影响,该文采用短针齿取代传统长针齿。实验结果显示,新的设计方案不仅能够有效减少剪切力和消除弯曲应力,而且能够显著减少啮合时打滑现象的发生,具有更高的安全系数。

    Abstract:

    RV (Rotor Vector) reducer is an important transmission device in the industrial robot system. It is usually composed by an involute planetary gear and a cycloidal pin wheel. In this paper, a novel analysis method of pins was proposed based on theoretical force analysis with the consideration of real wearing condition. By simulating the pins with the improved analysis method, shear force and bending stress on the pins can be calculated. To reduce the effect caused by shear force and bending stress, the short pins were used to replace traditional long pins. Experimental results show that, the usage of short pins not only can eliminate shear force and bending stress, but also decreases the occurrence of slippage during meshing, and that makes the RV reducer with higher reliability and longer service life.
