Different teeth profile shapes of polymer gears and comparison of their performance

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017
This article presents a lifespan testing analysis of polymer gears manufactured by cutting. Compared to injection molding, machine cutting provides higher accuracy of gear geometry. Two different tooth flank geometries were tested; i.e.

Accelerated lifetime testing of reinforced polymer gears

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
The main advantages of polymer gears compared to metal gears are low manufacturing costs for mass production, vibration damping, and there is no need for a lubricant.

A review on failure characteristics of polymer gear [PDF]

MATEC Web of Conferences, 2017
Polymer are now widely used as substitute material for steel gear in low load devices. Its failure differs from gears made of steel, thus it is important to categorize the failures shown by polymer gears.

A Contact Mechanics Model for Surface Wear Prediction of Parallel-Axis Polymer Gears. [PDF]

Polymers (Basel)
As surface wear is one of the major failure mechanisms in many applications that include polymer gears, lifetime prediction of polymer gears often requires time-consuming and expensive experimental testing. This study introduces a contact mechanics model
