Theoretical Research of Roller Enveloping the Side-worm Gear Pairs Drive

Abstract

Roller enveloping the side-worm gear pairs drive is proposed basing on roller enveloping hourglass worm drive. Roller enveloping the side-worm gear pairs drive means to assembling the roller on the end surface of the worm wheel equally. The hourglass worm tooth surface equation can be deduced by applying spatial meshing theory and differential geometry theory. The hourglass worm numerical models can be concluded by applying Matalb software to finish numerical simulation. At the same time ,this theory also focus on analyzing the roller radius R, orifice coefficient K1 , circumferential angle of worm gear for the meshing performance of this drive. According to the analysis, it can be concluded as that the roller radius is 5~20mm.
