摘要：

The definition of scroll compress profile rotation error sensitivity is put forward. According to the geometrical relation between profile rotation error sensitivity and radial mesh clearance, the computation method of radial mesh clearance under the nonideal state of orbit scroll rotation is provided. In addition, the effects of profile type, profile normal angle and orbit scroll rotation angle on the radial mesh clearance are analyzed and then an example is given to show the result. On the basis of the profile type and the correlation between profile normal angle and orbit scroll rotation angle, not only is a new reference index estimating profile performance obtained but also the criterion of determining profile error sensitivity region and blunt region is developed. According to this criterion, the assurance measurement for controlling the profile error in the sensitive region is presented. This measurement consequently plays a guiding role in reducing the mesh clearance and enhancing the compressor seal.
