The strength of gears differs depending on the type of material, heat treatment or quenching applied. A ground stock of any material is used on special CNC Swiss turning machines. Each of these materials plays an important role in the operation of the seal. Found insideFor more than 30 years the book Practical Gear Design, later re-titled Handbook of Practical Gear Design, has been the leading engineering guide and reference on the subject. Cemented carbide. But, for Modules 0.8 or smaller, KAG worm wheels mate with KKWG worms. 0000001016 00000 n
