The tooth profile is circular shape in, like umbrella , therefore , hence the name.
Spiralis a kind of driving medium that can low-noise and reposefully transmit according to jarless transmission ratio.
Spiral bevel gear has many advantage like efficient , stable transmission ratio , high circle overlap coefficient , high load ability , high carrying capacity , transmit placidly and plain sailing , reliable operation , compact structure , energy conservation , save space , stand wear and tear , long life and lower noise.
The transmission efficiency of spiral bevel gear is the highest in all kinds of mechanical transmission . To all kinds of transmission , especially high power drive , is provided with huge economic benefit . When passing the same torque , the space required of spiral bevel gear is smaller than belt drive and chain drive .The transmission ratio of spiral bevel gear is changeless forever.
Characteristics of Spiral Bevel Gears:
- Smooth and Quiet Operation: The helical teeth of spiral bevel gears result in gradual tooth engagement, leading to smoother and quieter operation compared to straight bevel gears. This makes them suitable for applications where noise reduction is important.
- High Load-Carrying Capacity: Spiral bevel gears distribute the load across multiple teeth, enhancing their load-carrying capacity and allowing them to handle higher loads and torque.
- Efficiency: The continuous contact between teeth in spiral bevel gears results in higher gear efficiency compared to straight bevel gears, especially at high speeds.
- Versatility: Spiral bevel gears can be used in a wide range of applications, including automotive, aerospace, industrial machinery, and marine systems.
- Precise Tooth Contact: Spiral bevel gears offer accurate tooth contact, ensuring reliable and precise motion transmission.
