Abstract
A gear train device for changing the angular relationship of an input gear relative to an output gear is disclosed. A pair of meshing gears to be checked are attached to the input and output gears to rotate therewith. By changing the angular relationship between the input gear and the output gear while the gear train is rotating, the gears to be checked are caused to contact the mating gear along a first tooth face while the angular relationship between the input gear and the output gear is urged in a first direction, and then the gears are caused to mesh along a second face when the output shaft is caused to move in an angular relationship to the input shaft in a second direction. By coating one of the gears to be checked with a material easily removed by rubbing, the gear profiles can be checked by measuring the amount of coating transfer between gears.
