Computation of Individual Errors from Single Flank Gear-Meshing Test : 1st Report, Pitch Errors and Tooth Profile Error of Spur Gear

Abstract

It was tried to compute pitch errors and tooth profile from single flank meshing test. Because tooth faces and flanks of a master gears which is composed with two parts was partially removed respectively, one pair meshing is always realized between the master gears and the test ones. Some kinds of pitch errors were obtained by compensating errors of the master gear from the transmitting error record. And the above mentioned records contain transmitting errors to tooth face and flank of the tested gears respectively. The superimposition of the records at a point of the curves gives a tooth profile of the test gears, The pitch errors and the profiles by the method are compared with the conventionally measured values. The pitch errors and the tooth profiles computed from the meshing test agree with them of the conventional measurement. Therefore this method shows a possibility of prompt measurement of gear error.
