Gear working processes for oil experimentations

Gear motor the sizing of the tooth surface stiffness, generally the gear is divided up into II classes, that is to say, hardened gear and soft tooth surface gear.

Normally a couple of meshing helical worm gearbox tooth surface hardness are larger than 350HBS, known as hardened gear, other is called a soft tooth surface right angle gearbox.

Accordant to the sizing of the tooth surface hardness, people generally gear is divided up into two categories, that is to say, hardened gear and soft tooth surface gear. Pick out the sort of gear drive concording to the project demands of the 2 gear drive their pros and cons, simply in hard gear transmission load, long life, made a widely range of applications programme*.

A lot of hardened gear materials and heat treatment process, such as many normally applied: 40Cr.45 # .45 Mn2 steel could be applied the ultimate heating handling of high-frequency tempering or nitriding 20Cr.20CrMnTi.20CrMnVB.20CrNiH etc. Could be applied seep carbon quenching, specified 38CrMnAl could be accomplished with a nitriding procedure a high up hardness, to apply a peculiar way of heat treatment of a few particular materials
