Item Description

Bevel gearbox of 135m ending mill

Composition of bevel gearbox:

Bevel gearbox, ordinate axis, bevel gear shaft, paired bevel equipment units and countershaft and bevel wheel units.

Specialized Functions:
one, Spherical helical gears and spiral bevel gear are manufactured by carbon metal, refined the firm and improve the resilience of the gear blank. Tooth area utilizing the carburizing techniques to attain large hardness, all tooth surface want to grind to increase the abrasive resistance and match precision.
two, ordinate axis, equipment shaft and countershaft adopt carbon steel elements to annealing, normalizing and adjustment to improve the tenacity and depth of the workpiece, all workpiece have the grinding procedure to insure the health and fitness. The assembled shaft and equipment has the balancing check , the speed is 4550 r / min, the balance amount is G1.
three,Box mildew by QT500-7 ductile iron, heat remedy is needed to guarantee stability.After roughing the box then make ultrasonic flaw detection, box and cover each bearing assembly bearing holes after finishing each case to ensure the overall accuracy, cabinet finishing finished oil hole cleaning, do 0.6MPa pressure test ensure no leakage.
four, The other components of cone box are mold by carbon metal. thermal refining process make confident the intensity of bevel gearbox. When the produce finished, Corrosion treatment is essential to improve the life span of workpiece.
5,When the assemble of  box completed, the no-load encounter is required to examination whether or not workpiece achieve the style prerequisite.


The performance of a worm equipment transmission is dependent to a large extent on the helix angle of the worm. Multi-threaded worms and gears with larger helix angles have verified to be 25% to 50% far more successful than solitary-threaded worms. The sliding motion of the worm meshing with or meshing with the worm gear outcomes in considerable friction and decline of effectiveness when compared to other types of gears. Enhance efficiency with hardened and ground worm change bronze worm gears.
