This paper describes a developed experimental test stand to measure transmission error in fine-pitch gears. The paper introduces the importance of transmission eror in office equipment that have uniform motion requirements. 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 can apply shaft allignment errors in both parallel and skew directions. Results from the test stand show the effect of gear elemental errors, transmitted load, and shaft misalignment on transmission mor in fine-pitch piastic gears.
