Supply Ability:


Bevel gears are used for transmission between intersecting shafts. Compared with cylindrical gears, it can change the transmission direction. Typical applications include drive axle in automobile, tractor and coal mining machinery.

The design, manufacture and installation of straight and helical teeth bevel gears are relatively simple. But they are noisy, and are used for low-speed transmission (<5m/s). The transmission power of straight teeth bevel gears can reach 400 kW and the peripheral speed over 5 m/s. The transmission of helical bevel gears runs smoothly and the load-bearing capacity of the gears is relatively higher than straight teeth bevel gear. However helical teeth bevel gears are difficult to manufacture. Thus their applications are rather limited.

Curved bevel gears have characteristics of smooth transmission, low noise and heavy-load carrying capacity. They are widely used in high-speed and heavy-duty conditions. Spiral teeth are typical type of curved bevel gear teeth. The transmission power of curve-tooth bevel gear can reach 4000 kW, and the circumferential speed can reach more than 40 m/s.



High strength alloy steel, eg. 18Cr2Ni4W, 20Cr2Ni4A, 17CrNiMo6, 18CrNiMo7-6, 20CrMnTi, 40CrNiMo, 30CrMnSi, 27SiMn, 35CrMo, 42CrMo, 40Cr, etc.

Allowable Torque (Nm)



Among various mechanical transmission types, the efficiency of spiral bevel gears is the highest, which has great economic benefits for various transmissions, especially high-power and heavy-duty transmissions. The space required to transmit the same torque is the least, smaller than belt or chain transmission. Besides, the transmission ratio of spiral bevel gears is permanently stable. Spiral bevel gears work reliably and have a long life.

Spiral bevel gears are widely used in domestic and foreign oil-field petrochemical machinery, machine tools, machining equipment, engineering machinery, metallurgical equipment, steel rolling machinery, mining machinery, coal mining machinery, textile machinery, shipbuilding machinery, aerospace, forklifts , elevators, reducers, aircraft manufacturing and many other industries.

Competitive Advantage

- capability of customization of straight teeth and spiral teeth bevel gear from drawings, 3D models, or simple part.

- capability of non-standard straight teeth and spiral teeth bevel gear manufacturing.

- integrity of manufacturing process including material choose, forge, fine machining, grinding, heat treatment, and surface treatment, etc.
