Contact and elastohydrodynamic analysis of worm gears, Part 1: Theoretical formulation

Article English OPEN
Sharif, Khairi; Kong, S.; Evans, Henry Peredur; Snidle, Raymond Walter;

The paper presents the theoretical basis for modelling the contact conditions and elastohydrodynamic lubrication (EHL) of worm gears, the results of which are presented in Part 2. The asymmetric elongated contact that typifies worm gears is non-Hertzian and is treated u... View more
