3 Overview

Measurement of relative measurement instrument gear tooth pitch, dual probe structure to any one of the measured gear pitch (or K tooth pitch) as the initial value of the pitch, followed by other gear pitch (a pitch or K) measurements were compared, thereby By other pitch (a pitch or K) with respect to the tooth deviation from the initial value, the use of a circumferential sealing characteristics that give each pitch deviation. The measurement principle is shown in Figure 1. Figure 1 relative method measuring principle 1- measured gear; 2- positioning probe; 3- activity probe; 4- indicator
