An Experimental Test Stand to Measure Loaded Transmission Error in Fine-Pitch Plastic Gears


This paper describes an experimental test stand to measure transmission error in fine-pitch gears. It covers the importance of transmission error control in office equipment. Transmission error is computed by measuring the phase difference between the driver shaft and the driven shaft using optical encoders. The test stand has a variable operating center distance and shaft alignment in both parallel and skew directions. Results show the effects of gear elemental errors, transmitted load, and shaft misalignment on transmission error in fine-pitch plastic gears.
