Computational Model for Analysing the Tooth Deflection of Polymer Gears. [PDF]

Polymers (Basel)
A computational model for analysing the tooth deflection of polymer gears is presented in this paper. Because polymer gears have less stiffness compared to metal gears, the proposed approach considers a comprehensive analysis to determine the most ...
