Analysis of Transient Elastohydrodynamic Lubrication of Asymmetric Polymer Gear
Jixie chuandong, 2021 Polymer gears are light and corrosion resistant， which can reduce noise and improve economic benefits. Correspondingly， polymer gear teeth are weaker than metal ones， so asymmetric design is adopted to improve the strength of polymer gear.
