1) Description of Spiral Bevel Gear
From the perspective of load adaptation, spiral bevel teeth are bevel gears that can design structural parameters
(such as modulus and tooth width) according to different load sizes and properties (such as impact load, stable load),
and can adapt to a variety of load conditions.
2) Feature of Spiral Bevel Gear
It has strong bearing capacity to impact loads, and the spiral structure of the gear teeth can disperse impact energy;
under stable loads, the transmission efficiency is stable and the operation is reliable; through optimized parameters,
it can be adapted to different loads of light, medium and heavy loads, and has wide adaptability.
3) Working Principle
When under load, the teeth of the helical bevel tooth evenly distribute the load on multiple teeth through the spiral surface,
reducing the force of a single tooth.
4) Application of Spiral Bevel Gear
It is used in hydraulic transmission systems for construction machinery, adapted to intermittent impact loads;
it is also used in reducers for mining equipment, and endured continuous heavy loads.
