Research on Assessing Algorithm for Scroll-type Cylinder Surface Perpendicularity Errors

Hu Ronghua;Wang Lun;Chen Zhongyang;Liu Guoping;Nanchang University;  
In order to achieve high-precision assessment of scroll-type cylindrical surface perpendicularity in scroll compressors,a mathematical model was established based on the least square method of the optimization approximation algorithm and was used to analyse the scroll surface outline data.Comparing the results herein with results from the German ZEISS company UMC 550type of CMM,it shows that the algorithm is accurate and targetable.The curve of the result from the algorithm has the same trend with the result curve of ZEISS and the degree of coincidence is more than 99%.It can be assessed as a high-precision algorithm of the wrap perpendicularity.
