A Measurement Method of Circular Pitch Error and Total Cumulative Pitch Error Based on Large-size Gears

The comparative measurement method based on the laser tracker measurement system is proposed in this paper to measure the circular pitch error and total cumulative pitch error of the large-size gear. Compared with the traditional measurement method, this method can improve the measurement range about circular pitch error and total cumulative pitch error. The principle of the comparative measurement method is discussed, the calculation model of circular pitch error and total cumulative pitch error is derived and the measurement problem of the circular pitch error and total cumulative pitch error is solved. High accuracy of about 0.01 mm/m can be achieved with this measurement method.
