High quality alloy cast steel ball mill ring gear for mining cement
The big gear is divided into two halves, and the tooth width is y-shaped to ensure the good rigidity of the gear. Both sides of big gear flange are machined, both can match with cylinder flange, and can be used by turning around. Pinion and shaft are forged as a whole, both ends of shaft are symmetrical, both milling has keyway, can also be used for turning.
The gear is made of ZG35CrMo alloy cast steel with heat treatment hardness OF HB260 ~ 300. Pinion material is 17CrNiMo6, carburizing and hardening + grinding process, tooth surface hardness HRC57 ~ 61.
(1) Pinion gear
1) Vacuum arc smelting, ladle refining, vacuum degassing materials are adopted
2) Forging in accordance with international standards, ultrasonic inspection forgings
(2) Big gear
1) Casting adopts full ring riser technology
2) The application of simulation program, determine the appropriate curing process, determine the gate, slope, riser appropriate size, improve casting quality, reduce defects and reduce costs;
3) Precision gear processing equipment, improve the accuracy and gear surface roughness;
4) Finite element analysis of structural stress and deflection deflection of large gear, so as to determine the shape modification of pinion;
5) When the big gear is processed on the machine tool, check the meshing of the pinion after finishing to ensure that the tooth shape and tooth direction of the two are completely consistent.
