3 Overview
Gear measuring instruments can be divided into mechanical and numerical control.
3.1 Mechanical gear measuring instrument involute measurement principle
Mechanical gear measuring instruments are single disc type, grading disc type and lever disc type, etc. It is based on gear involute
The principle of exhibition, the theoretical involute is generated by the mechanical mechanism, and the actual curve and theory of the device under test are opened by the sensor.
The line trajectory is compared, and the difference is input to the recorder to give an involute deviation curve. Its structure is shown in Figure 1.
3.2 Induction line measurement principle of numerical control gear measuring instrument
The numerical control gear measuring
