Abstract

A three-dimensional coordinate evaluation method for gear errors was explored to eliminate the influence of positioning error of a measurement instrument on the measurements and evaluations of a gear and to improve the measuring accuracy. The traditional two-dimensional gear error evaluation method was analyzed

and then the gear error evaluation model was changed from two-dimensional evaluation model into three-dimensional evaluation model. In the three-dimensional evaluation model

the measurement points of gear error were not required in the characteristic surface

and error measurement and evaluation of gear could be realized in a three-dimensional space. Furthermore

to improve the efficiency of three-dimensional evaluation algorithm of gear errors

three-dimensional data were reduce to two-dimensional data by using spiral dimensionality reduction method

and the error evaluation of two-dimensional measurement data were carried out. By taking the in-site measurement system with laser tracker for megagear as an experimental object

the profile error of a 4 level standard gear was measured

and obtained results were compared with that of the traditional two-dimensional gear error estimation method and the evaluation results from the InvolutePro software of German ZEISS company. The experimental results indicate that the traditional two-dimensional evaluation method has a bigger error

but the proposed three dimensional evaluation method can obtain the same evaluation results with the software of InvolutePro of German ZEISS company

and the algorithm precision reaches 0.1μm. The results verify that proposed three dimensional evaluation method is correct. It eliminates the influence of instrument positioning precision on gear error measurement and improves the measurement precision of gear measuring instruments.
