Vibration based fault detection of polymer gear

Materials Today: Proceedings, 2021
Abstract Gears are used to transmit power and motion from one shaft to another under varying speeds and loads. In many applications, metal gears have been replaced by polymer-based gears. Polymer gears possess some unique properties over metal gears, such as self - lubrication, less weight, and low noise emission.

Efficiency of polymer gears

Polymer gears offer advantages such as good tribological performance, self-lubrication, low cost, lightweight design, and minimal vibration. They can be used in mechanisms where lubrication is not needed to prevent contamination from lubricants. Minimizing heat generation is crucial to maintain the optimal tribological properties of these gears.
