Bevel Gearbox of 90m Finishing Mill-1117-09

Composition of bevel gearbox
Bevel gearbox, vertical axis, bevel gear shaft, paired bevel gear units and countershaft and bevel wheel units.
Technical Features
1, Cylindrical helical gears and spiral bevel gear are made of low carbon steel, refined texture enhances the resilience of the gear blank. In order to increase the abrasive resistance of the gear, tooth surface adopt the carburizing and quenching techniques to achieve high hardness,
2, Medium carbon steel made vertical axis, gear shaft and countershaft are processed by annealing, normalizing, hardening and tempering to enhance the tenacity and intensity of the workpiece, all workpieces are grinded to promote the precision. The assembled shaft and gear have the balancing test, the speed is 4550 r / min, the balancing precision grade is G1.
3, Box is mold by ductile iron and use the aging heat treatment to insure the stability. The bearing location between box and its cover is the key to ensure the total accuracy.
4, The other parts of cone box are mold by carbon steel. Thermal refining process make sure the intensity of bevel gearbox. When the produce finished, Corrosion treatment is needed to increase the lifetime of workpiece.
