Spiral bevel gears usually have a circular arc shape, and are also known as bevel gears due to their shape resembling an umbrella. Bevel gears are rotating parts that can stably transmit and have low noise during rotation. Due to the high rotational efficiency and stability of bevel gears, as well as their high load-bearing capacity, compact structure, energy-saving and material saving, space saving, wear resistance, and long service life, they are widely used in various mechanical equipment. Compared to belts, chain drives, etc., it requires less space for rotation and is stable, making it a more reliable mechanical component
