There are many kinds of knurling patterns, which are roughly straight, twill, and net. Among them, there are diamonds and squares, which are 30° and 45°. According to the national standard GB6403.3-86, the knurling pattern It is calculated by modulus, there are four kinds of 0.2, 0.3, 0.4, 0.5, and its P value (pattern tooth distance, unit mm) is 0.2=0.628, 0.3=0.942, 0.4=1.257, 0.5=0.571. Metric and imperial, the P value of the British system is calculated according to the number of teeth per inch; the metric P value is 0.1 per specification, ie 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 1.0, 1.2, 1.4, 1.6, etc

Tips for preventing metal gear distortion:
1. Controlling the quality of raw materials: High-quality raw materials are prerequisites for the production of high-quality products. No matter what route, raw materials must pass strict chemical composition inspection, grain size measurement and purity evaluation after they arrive at the factory. Adjust the heat treatment deformation in time to improve the quality of the tooth profile processing.

2, control gear accuracy: gear accuracy must be controlled, line speed is higher than 20m / s gear, pitch limit deviation, ring gear radial runout tolerance, tooth tolerance must be stable to 7 level accuracy. In the case of a 7-stage precision gear, the tooth should be reversed, and the root boss should be strictly guarded.
3. Prevent heat treatment deformation: After rough machining, the tooth blank becomes a precision forging, and is subjected to normalizing or quenching and tempering treatment to eliminate residual force and soften the steel for cutting
