Driven by regulations for better efficiency, gear manufactures are pursuing new processing methodologies to create smoother gears and lower friction between interacting surfaces. Fine grinding and super-finishing produce efficient surfaces with better matched surfaces for sliding.
As these surfaces become smoother, tactile and other analysis methods will become more difficult as they can result in scratching the surface or simply not able to reach the area of interest because of the form or size of the stylus tip.
- New manufacturing methods will decrease gear flank surface texture thereby improving sliding action and reducing surface strain.
- Overall tribology will enhance running of gears, decreasing noise and vibration along with seeing increases of vehicle efficiency from 8 to 20% in the powertrain.
