Bevel gears

Conical gears, also known as bevel gears, are used for power transmission between intersecting shafts. Compared to cylindrical gears, they can change the direction of transmission. The single-stage transmission ratio can reach up to 6, or even 8.

1. Straight and helical bevel gear designs, manufacturing, and installation are relatively simple, but produce more noise; suitable for low-speed transmission (<5 m/s). The power transmission of straight bevel gears can reach 370 kW with a peripheral speed of 5 m/s. Helical bevel gear drives operate smoothly with higher gear load-bearing capacity, though manufacturing is more challenging and applications are less frequent.

2. Curved-tooth bevel gears feature smooth transmission, low noise, and high load-bearing capacity, suitable for high-speed and heavy-duty applications. These gears operate smoothly, capable of transmitting power up to 3,700 kW and peripheral speeds exceeding 40 m/s.
