Alloy Cast Steel Customize Ball Mill Girth Gear / Pinion Gear For Mining Equipment
1. Features of mill girth gear customize ball mill gear ring
The helical gear has the characteristics of high bearing capacity, smooth operation and low noise.
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.
2. Introduction of big gear and small gear of mill girth gear
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
A. Vacuum arc smelting, ladle refining, vacuum degassing materials;
B. Forging in accordance with international standards, ultrasonic inspection forgings;
(2) Big gear
A. Casting adopts full ring riser technology;
B. Use the simulation program to determine the appropriate curing process, determine the appropriate size of the gate, slope and riser, improve casting quality, reduce defects and reduce costs;
C. Precision gear processing equipment, improve the accuracy and gear surface roughness;
D. Finite element analysis of structural stress and deflection deflection of large gear, so as to determine the shape modification of pinion;
E. 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.
3. Processing technology measures of mill girth gear customize ball mill gear ring and pinion
