几何的法线方向的螺旋，可以用来计算的坐标转子螺旋 和 的从x和y的间隙加入如：

其中分母D被给定为：

如果以任何方式，转子的改变它们的相对位置，该间隙的平侧面上分布在转子的一端，也可以减少到零的转子叶片。在这样的情况下，转子的接触将是令人望而却步长侧扁的档案中，其中占主导地位的相对滑动转子运动，如示于图。 2.29。这表明，转子扣押几乎肯定会
如果转子进入彼此接触，发生在该区域。

The direction normal to the helicoids, can be used to calculate the coordinates of the rotor helicoids   and   from x and y to which the clearance is added as:

 ，   ，        （2.19）
where the denominator D is given as：
              （2.20）
  and  serve to calculate new rotor end plane coordinates, x0n and y0n,with the clearances obtained for angles θ =  /p and τ respectively. These   and   now serve to calculate the transverse clearance δ0 as the difference between them, as well as the original rotor coordinates   and  .
If by any means, the rotors change their relative position, the clearance distribution at one end of the rotors may be reduced to zero on the flat side of the rotor lobes. In such a case, rotor contact will be prohibitively long on the flat side of the profile, where the dominant relative rotor motion is sliding, as shown in Fig. 2.29. This indicates that rotor seizure will almost certainly occur in that region if the rotors come into contact with each other. [资料来源：www.doc163.com]
