In this paper, in studying absolute Angle measurement principle basis designed coding rules of a Single-ring code and formulated the appropriate software algorithm.
The profiles are calculated in such a way that, under normal load conditions, life-reducing edge stresses do not occur at a tilting angle of up to 4' between inner ring and outer ring (Table 5.2).
The paper begins with the introduction of traditional methods to measure the trapezoid angle and the ring height, analyzes their characters and limits.
