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 transmis on abiliy dec s e of l an e ucan oil with xtreme pressure
additive has good lubricating effect on the hardened TI worm gearing
Key words: Worm gearing Gearbox Grinding wheel Transmission efficiency
Ⅱ蜗杆传动具有线接触,多齿对同时啮合,瞬时接
前
触线与相对滑动速度夹角接近直角即润滑条件好等
特点。蜗杆副中的蜗轮是普通的渐开线斜齿轮,
蜗杆传动即渐开螺旋面包络环面蜗杆传动,便于高精度的磨削加工和修形。因而只要实现TI
它是由渐开线斜齿轮及其包络的环面蜗杆即T蜗蜗杆的精确磨削加工,就有可能实现硬齿面副的T
杆组成的蜗杆传动。文献[]及WANG等均阐明了蜗杆传动,为取代贵重有色合金而采用钢一钢配对
的蜗杆材料副提供了可能。
