摘要: TI蜗杆传动由渐开线斜齿轮和其包络的环面蜗杆组成。按照有关TI蜗杆传动主要设计参数选择方法的研究结果,给出一对TI蜗杆传动副的具体设计参数,利用研制的砂轮修整器和专用磨头,在滚齿机上实现了TI蜗杆齿面的磨削加工,完成了钢-钢配对的硬齿面副TI蜗杆减速器的制造。采用两种常用的工业润滑油,开展了硬齿面副TI蜗杆传动性能试验,重点测试了蜗杆传动的输入输出转矩、油池温度、运转时间和箱体振动值,对蜗杆传动效率及其影响因素进行分析。结果表明,硬齿面副TI蜗杆减速器在较低的载荷下具有较好的机械传动性能,但随着载荷的增加,齿面间摩擦磨损加剧,传动稳定性下降,含极压添加剂的润滑油对硬齿面的TI蜗杆传动具有较好的润滑效果。

Abstract: TI worm gearing consists of involute helical gear and its enveloping hourglass worm. According to the previous research result of the parameter choice method of the worm gearing design, the design parameters for TI worm gearing are given. By utilizing a grinding wheel dresser and a special grinding head, the grinding process for TI worm tooth surface is realized on gear-hobbing machine. The hardened TI worm gearbox reducer is made with steel wheel teeth. Experimental research for testing transmission performance is carried out with two kinds of industrial lubricating oil. The input and output torques, box oil temperature, driving time and box vibration are measured. The worm transmission efficiency and its effect factors are analyzed. Test results show that the TI worm gearing reducer with hardened teeth has good transmission performance while the load is in low condition, the tooth friction wear becomes severe and transmission stability declines with the increase of load, and the lubricating oil with extreme pressure additive has good lubricating effect on the hardened TI worm gearing.
