“…The wear progress was monitored by regular measurement of the circumferential backlash for numerous mesh positions within one revolution of the worm wheel. The method described in [17] was applied to measure highly resolved backlash curves under low load contact conditions and to evaluate the backlash increase for identical mesh positions. According to [17], the backlash increase caused by wear varies within one pitch period, because of varying wear along the contact path and load sharing.…”

Wear phenomena in worm gears are dependent on the size of the gears. Whereas larger gears are mainly affected by fatigue wear, abrasive wear is predominant in smaller gears. In this context a simulation model for abrasive wear of worm gears was developed, which is based on an energetic wear equation. This approach associates wear with solid friction energy occurring in the tooth contact. The physically-based wear simulation model includes a tooth contact analysis and tribological calculation to determine the local solid tooth friction and wear. The calculation is iterated with the modified tooth flank geometry of the worn worm wheel, in order to consider the influence of wear on the tooth contact. Experimental results on worm gears are used to determine the wear model parameter and to validate the model. A simulative study for a wide range of worm gear geometries was conducted to investigate the influence of geometry and operating conditions on abrasive wear.
