What is the difference between the soft tooth surface and the hard tooth surface of the reducer?
May 16, 2018

According to the size of the tooth surface hardness of the reducer, the gear transmission is usually divided into two kinds, namely, the hard tooth surface gear drive and the soft tooth surface gear transmission.

Normally, the tooth surface hardness of a pair of meshing gears is greater than 350HBS, which is called the hard tooth surface gear, otherwise known as the soft tooth surface gear.


According to the size of the tooth surface hardness, the gear transmission is usually divided into two types, namely, the hard tooth surface gear drive and the soft tooth surface gear transmission. Select the gear drive according to the design requirement, two kinds of gear drive each has the advantages and disadvantages, but has the hard tooth surface transmission load is large, the service life is long, has the extensive application.


Hard tooth surface gear adopts the material and heat treatment method are many, such as the commonly used several kinds: 40 cr. 45 #. 45 mn2 can use high frequency tempering heat treatment or nitride steel processing, such as 20 cr. 20 crmnti. 20 CRMNVB. 20 crnih carburizing and quenching can be used, such as such as 38 crmnal can by nitriding process to achieve high hardness, some special material to use special heat treatment method.
