Introduction To The Difference Between The Hardness Of The Tooth Surface Of The Reducer

According to the hardness of the tooth surface of the reducer, people usually divide the gear transmission into two categories, namely the hard tooth surface gear transmission and the soft tooth surface gear transmission.

Generally, the hardness of the tooth surface of the meshing gear is greater than 350HBS, which is called a hard tooth surface gear, otherwise it is called a soft tooth surface gear.

According to the hardness of the tooth surface, people usually divide gear transmission into two categories, namely hard tooth surface gear transmission and soft tooth surface gear transmission. The choice of the gear transmission should be based on the design requirements. The two types of gear transmission have their own advantages and disadvantages, but they have the advantages of large transmission load and long service life with hard tooth surfaces, and are widely used.

There are many materials and heat treatment methods used for hard tooth surface gears, such as the commonly used ones: 40Cr .45# 45Mn2 steel can adopt final heat treatment, high frequency tempering or nitriding treatment, such as 20Cr.20CrMnTi.20CrMnVB.20CrNiH, etc. can be carburized and quenched , Such as 38CrMnAI can use nitriding process to achieve higher hardness, some special materials to use special heat treatment methods.
