ベベルギアの3種類は何ですか？

ベベルギアストレートベベルギア、らせん状のベベルギア、湾曲したベベルギアなど、いくつかのタイプに分かれています。ストレートベベルギアは、軸方向の力と高いノイズを持ち、低速トランスミッションに使用されます（<5m/s); The helical bevel gear has a high degree of overlap and low noise; Curved bevel gear transmission is stable, with low noise and high load-bearing capacity. It is used in high-speed and heavy-duty situations, with a transmission power of up to 3700 kW and a circumferential speed of over 40 meters per second. Umbrella gears are widely used in the transmission of intersecting axes in automobiles, machine tools, tractors, and other machinery. At present, powder metallurgy can only produce spur bevel gears, which has advantages such as low cost and good wear resistance.
