introduction：inIKOBearing grinding process，Grinding wheel and workpiece contact zone，Consume a small amount of energy，A small amount of grinding heat occurs，The part of the grinding zone that forms the time low temperature。The practical formula of heat transfer from linear stationary heat source is applied、Calculate or use the red inner line method and thermocouple method to measure the braking temperature under test conditions，Inventible in0.1～0.001msThe braking temperature of the inner grinding zone can be as high as1000～1500℃。This is a cold brake，Cryogenic oxidation occurs in the outer layer, which is sufficient to give the mission surface a certain depth，Amorphous structure、Low temperature tempering、Secondary quenching，Even burns and cracks and other changes。 The first factor

introduction：Try to use close to the ideal deceleration ratio： Reduction ratio=Motor speed/Speed of output shaft of reducer Torsion calculation： For the life of the reducer,Torque calculation is very important,And pay attention to the maximum torque value of acceleration(TP),Whether it exceeds the maximum load torque of the reducer. Decelerating model number selection and precautions： The applicable power is usually the applicable power of the servo machine on the market,The applicability of the reducer is very high,The working coefficient can be maintained at1.2above,But in the selection can also be determined by their own needs: There are two main points
