To conduct tolerance analysis of gears more effectively and reasonably
a new tolerance analysis modeling approach for gears based on small displacement torsor(SDT)and response surface method is proposed. Taking the installation tolerance of a gear for example
the mathematical model for installation tolerance of the gear is built based on SDT theory and in accordance with gear precision standard. Based on this model and tooth contact analysis(TCA)
a simulation program considering the errors is coded and the effects of different variation factors on transmission error are analyzed. A second-order response surface approximate model of gear transmission error is built based on Latin hypercube sampling and the least squares method
hence the tolerance analysis model of gears is obtained. An example is analyzed and the result indicates that the proposed method has high modeling accuracy and good practicability
and may provide a reference for gear tolerance analysis and synthesis.
