introduction： According to the hardness of the gear surface of the reducer，Gears are generally divided into two categories，Namely hard tooth surface gear drive and soft tooth surface gear drive。 Generally, the tooth surface hardness of a pair of meshing gears is greater than350HBS，It is called hard face gear，Otherwise it is called soft face gear。 According to the hardness of the tooth surface，Gears are generally divided into two categories，Namely hard tooth surface gear drive and soft tooth surface gear drive。The choice of gear drive depends on the design requirements，Both gear drives have advantages and disadvantages，However, the transmission load is large on the hard tooth surface，Service life
