Bevel gear

umbrellagear, Namely bevel gear (Bevel), bevel gear. Used for transmission between intersecting shafts.

The single-stage transmission ratio can be up to 6, the maximum is 8 or above, and the transmission efficiency is generally 0.94 to 0.98.

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 (<5m/s); the transmission power of spur bevel gears can reach 370 kilowatts, and the peripheral speed is 5 meters. /second.The transmission of helical bevel gears runs smoothly, and the load-bearing capacity of the gears is high, but it is difficult to manufacture and has fewer applications.

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