The Effect of Teeth Correction in an Archimedes Worm Gear on the Contact Strength, Wear, and Life of the Worm Gear Teeth

Abstract

The paper presents a method for determining the effect of teeth correction in an Archimedes worm gear on the contact strength, wear, and life of teeth of the worm wheel. The regularities regarding the effect of correction on contact and tribocontact parameters are established.

“…Czerniec et al [8] present a method of calculating the effect of tooth correction of a worm drive with an Archimedes' screw on the contact strength, wear, and durability of the worm gearwheel teeth. The results of the study establish the correctness of the correction effect on the contact parameters and tribological contact.…”

“…Based on the numerical solution, a relationship between the drive resource and wear was determined. Also, Czerwiec and Kiełbiński present a method of calculating the lifespan of a worm drive with a involute worm screw [8]. The result of the numerical solution was used to determine the characteristics of the dependency between the lifespan of the transmission and the linear wear of the worm gearwheel teeth.…”
