Bevel gears are also called bevel gears, bevel gears. For transmission between intersecting shafts. Compared with cylindrical gears, it is possible to change the direction of transmission. Single-stage ratios can be up to 6 and up to 8.
1. The design, manufacture and installation of straight and helical bevel gears are relatively simple, but the noise is large, and they are used for low-speed transmission (<5m/s); The straight bevel gear transmission can transmit power up to 370 kW and a circumferential speed of 5 m/s. The helical bevel gear transmission runs smoothly and the gear bearing capacity is high, but it is difficult to manufacture and less applied.
2. The curved bevel gear has the characteristics of stable transmission, low noise and large bearing capacity, and is used in high-speed and heavy load occasions. The curved bevel gear transmission runs smoothly, the power can be transmitted to 3700 kW, and the circumferential speed can reach more than 40 m/s.
Bevel gears are divided into spur bevel gears, helical bevel gears, etc.
