Prediction Method of Contact Pressures, Wear and Life of Worm Gears with Archimedean and Involute Worm, Taking Tooth Correction into Account

Abstract

This study evaluates the computation method of the study of worm gears with Archimedean and involute worms when engagement correction is presented, based on the contact pressures and the wheel teeth wear, as well as the gear life and the sliding speed in the engagement. The regularities of influence of correction on the stated gears parameters are stated. When there are positive values of the correction coefficient of wheel teeth, the maximal contact pressures and the linear wear of wheel teeth decrease as compared with the noncorrected gear, and when the correction coefficient is negative they increase. The stated regularities are represented in a diagram form.
