Bevel gears are bevel gears and bevel gears. Bevel gears are most commonly used for transmission of two vertical shafts, but they are also suitable for transmission of two shafts at other angles. The most typical application is to drive a vertical pump with a horizontal drive device. The two main differences between bevel gears and spur gears are their shape and their relationship to the axis on which they are located. The bevel gear is conical in shape, while the spur gear is originally a cylinder. The bevel gear transmits the movement between two angled shafts, that is, the cross shaft, while the spur gear transmits the movement between the two parallel shafts. It is widely used in printing equipment, automobile differentials, and sluices. It can also be used in locomotives, ships, power plants, steel plants, railway track inspections, etc.

Compared with metal gears, plastic gears are economical, have a long wear-resistant life, and are highly functional.

1. The design, manufacture and installation of spur and helical bevel gears are relatively simple, but they are noisy and are used for low-speed transmission (GG lt; 5m/s); the transmission power of spur bevel gears can reach 370 kilowatts at a peripheral speed 5 meters per second. The transmission of helical bevel gears runs smoothly and has a high load-carrying capacity, but it is difficult to manufacture and has fewer applications.

2. Curved bevel gears have the characteristics of stable transmission, low noise and large carrying capacity, and are used in high-speed and heavy-duty situations. Curved bevel gear transmission runs smoothly, the transmission power can reach 3700 kilowatts, and the circumferential speed can reach more than 40 m/s.
