Machine tool gear commonly used materials and heat treatment processing instructions

The commonly used materials and heat treatment processing instructions for machine tool gears are as follows, for reference and understanding. For unclear parts or related requirements, you can consult EP for free.

everybody knowsMachine GearIt can be divided into low speed (speed 2m/s, unit pressure 350-600N/mm^2), medium speed (speed 2-6m/s, unit pressure 100-1000N/mm^2, impact load is not large) and high speed (speed 4-12m/s, the bending moment is large, the unit pressure is 200-700N/mm^2), but do you know the common materials and heat treatment details of products with different requirements, as follows:

1. 20Cr carburizing, quenching, low temperature tempering HRC56-62, used for high speed, pressure, medium, and impactgear.

2. 40Cr quenched and tempered, HB220-250, used for gears with low peripheral speed and medium unit pressure, quenching and tempering, HRC40-50, used for gears with medium peripheral speed and low impact load.

3. 45 quenching, high temperature tempering, HB200-250, used for peripheral speed <1m/s, medium pressure, high frequency quenching, surface hardness HRC52-58, used for gears with high surface hardness and small deformation.

4. In addition to the above conditions, if small deformation is required during heat treatment, high-frequency quenching with hardness HRC52-58 is used.
