摘要: 精密减速器,尤其是RV减速机,是工业机器人中最为关键的功能部件,其精密制造成形已经成为当代工业机器人研发与应用的一项重大技术挑战。在此基础上针对工业机器人产业对高精度、高可靠性RV减速机需求,开展精密摆线轮冷精整挤压加工成形工艺研究,分析挤压精整量和挤压次数对摆线轮廓精度的影响。研究结果表明,采用冷精整加工工艺可以制造出高精度的摆线轮,精整量是摆线轮廓精度最主要的影响因素,最优精整量参数为0.05 mm。此外,结合正反两次挤压能够进一步提升摆线轮廓精度。该工艺能够显著提升生产效率,大幅度降低制造成本,为摆线齿轮低成本快速精密加工成形提供了具有重要价值的指导。

Abstract: Precision reducer, especially RV reducer, is the most critical functional component of industrial robot. Its precision manufacturing has become a major technical challenge for the development and application of modern industrial robots. Aiming at requirements of high precision and high reliability RV reducer in the industrial robot industry, a cold precision extrusion technology for cycloidal gear is developed. The effects of extrusion fishing amount and the extrusion times on the precision of the cycloidal gear are also analyzed. The results show that the cycloidal gear with high precision can be fabricated by cold precision extrusion technology. The extrusion fishing amount is the main factor that affects the precision of the overall cycloidal gear. The optimal extrusion fishing amount is obtained to be 0.05 mm in this study. In addition, combining the direct extrusion and reverse extrusion can further improve the accuracy of the cycloidal gear. The manufacturing process, which enables to significantly improve production efficiency and remarkably reduce the manufacture cost, provides a significantly valuable guidance for low-cost rapid precision forming of cycloidal gears.

Key words: RV reducer, cycloidal gears, cold precision extrusion, extrusion times, gear accuracy
