Optimal Polymer Gear Design: Metal-to-Plastic Conversion

May 1, 2020
Nowadays, the progress in polymer materials and injection molding processing has enabled a drastic expansion of plastic gear applications. They are used not only for lightly loaded motion transmissions, but also in moderately loaded power drives in automotive, agriculture, medical, robotics, and many other industries.

A Comparative Study of Polymer Gears Made of Five Materials

November 1, 2019
The wear behavior of polymer gears made of five different materials has been investigated using an existing polymer gear test rig. Step loading tests at a constant speed of 1,000 rpm were performed. Significant differences in failure modes and performance have been observed for the five polymer gear materials for gear engagements of gears, with the same material as each other.

Plastic Gear Design Remains a Work in Progress

July 1, 2018
Despite the development and availability of a number of newly engineered, rugged materials intended for plastic gear applications, some engineers/designers continue to believe metal is better.

Tooth Contact Analysis - Off Line of Action Contact and Polymer Gears

September 1, 2017
Dr. Paul Langlois
The aim of the study was to apply such a specialized tooth contact analysis method, well-used within the steel gear community, to a polymer gear application to assess what modifications need be made to these models for them to be applicable to polymer gears.

Plastic Gearing Continues Converting the Unconverted

March 1, 2016
Plastic gears are everywhere today - throughout your car, at the oceans' lowest depths, in deep space. The question, when is a metal gear a candidate for plastic conversion, can be addressed in three words, i.e. what's the application?

At the PEEK of the Polymer Food Chain

June 1, 2010
In the hypercompetitive race to increase automobile efficiency, Metaldyne has been developing its balance shaft module line with Victrex PEEK polymer in place of metal gears. The collaborative product development resulted in significant reductions in inertia, weight and power consumption, as well as improvement in noise, vibration and harshness (NVH) performance.

Non-Standard Cylindrical Gears

November 1, 2004
Curved face width (CFW) spur gears are not popular in the gear industry. But these non-metallic gears have advantages over standard spur gears: higher contact ratio, higher tooth stiffness, and lower contact and bending stresses.

Load Carrying Capacity of Screw Helical Gears with Steel Pinions and Plastic Wheels

July 1, 2004
There is an increasing significance of screw helical and worm gears that combine use of steel and plastics. This is shown by diverse and continuously rising use in the automotive and household appliance industries. The increasing requirements for such gears can be explained by the advantageous qualities of such a material combination in comparison with that of the traditional steel/bronze pairing.

Optimizing Plastic Gear Geometry: An Inroduction to Gear Optimization

May 1, 2002
There are numerous engineering evaluations required to design gear sets for optimum performance with regard to torque capacity, noise, size and cost. How much cost savings and added gear performance is available through optimization? Cost savings of 10% to 30% and 100% added capacity are not unusual. The contrast is more pronounced if the original design was prone to failure and not fit for function.
