The wear behaviour of polymer composite gears

Journal of Synthetic Lubrication, 1996
AbstractIn order to examine the wear of polymer composite gears, a test facility has been developed which has enabled the wear of gear trains to be measured continuously during gear operation. Brief details of the method are given. The purpose of this paper is to report some of the results obtained from this facility and, in particular, to discuss the ...

Friction and Wear of Engineering Polymer Gears

World Tribology Congress III, Volume 2, 2005
Technical polymers are widespread in the machinery owing to their beneficial properties against metals as operation without lubrication, low friction and wear, light weight, corrosion resistance, low manufacturing costs etc. There are many sorts of technical polymers available of which sliding elements can be produced.

Engine NVH performance improvements with polymer gears

2019
Legislation drives the automotive megatrend to reduce fuel consumption and CO2 is resulting in small high output 3 and 4 cylinder engines. While customers have raised expectations on driving comfort, the smaller high output engines have inherent vibration noise, vibration and harshness (NVH) issues.

Advancing Dynamic Polymer Mechanochemistry through Synergetic Conformational Gearing

Journal of the American Chemical Society
Harnessing mechanical force to modulate material properties and enhance biomechanical functions is essential for advancing smart materials and bioengineering. Polymer mechanochemistry provides an emerging toolkit for exploring unconventional chemical transformations and modulating molecular structures through mechanical force. One of the key challenges

Performance of gear pumps in polymer processing

Polymer Engineering & Science, 1984
AbstractWithin the past several years considerable interest has developed in the practice of retrofitting plasticating extruders with gear pumps. The primary motivation for this is to reduce surges and fluctuations in the extrusion rate, thereby improving product quality and reducing waste.

Abrasive wear of polymer/steel gear drives

Progress in Agricultural Engineering Sciences, 2008
Research was performed on the friction, wear and efficiency of plastic gears made of modern engineering polymers and their composites both in a clean environment (adhesive sliding surfaces) and in an environment contaminated with solid particles and dust (abrasive), with no lubrication at all.
