Spiral bevel gears are widely used in mechanical transmission fields such as automobiles, aviation, and mining due to their large overlap coefficient, strong bearing capacity, high transmission ratio, stable transmission, and low noise.
There are two types of spiral bevel gears: the first is a spiral bevel gear where the large wheel axis intersects the small wheel axis, and the second is a hypoid spiral bevel gear with a large offset between the large and small wheel axes. The world’s leading producers of spiral bevel gears are Gleason Corporation of the United States and Olympus of Switzerland.
Within the bevel gear category, there are spur gears and curved gears, depending on the tooth length direction of the teeth. Straight bevel gears are straight lines that intersect the tooth length contour and the pitch cone surface. If the gear is a curve, it is referred to as a curved gear. For now, spiral bevel gears should be considered synonymous with curved bevel gears.
There are three types of spiral bevel gears that belong to different companies and are based on different curves. These include the Hypton gears designed by Gleason Corporation (including arc bevel gears), extended pylon gears from Olympus, Switzerland, and quasi-involute gears from Klingenberg, Germany.
Spiral bevel gears are transmission components that offer smooth and low-noise operation with a stable transmission ratio. Different regions have different names for spiral bevel gears, such as spiral bevel gears, spiral bevel gears, spiral bevel gears, arc bevel gears, and so on.
The features of spiral bevel gears include:
- High transmission efficiency
- Stable gear ratio
- Large arc overlap coefficient
- High carrying capacity
- Smooth and smooth transmission
- Reliable work
- Compact structure
- Energy saving
- Save space
- Long life
- Low noise
Among various mechanical transmissions, spiral bevel gears have the highest transmission efficiency, which results in significant economic benefits for different types of transmissions, especially high-power transmissions.
The space required for transmitting the same torque is the most compact for spiral bevel gear transmissions compared to belt and chain transmissions.
Spiral bevel gear transmissions offer permanently stable transmission ratios, which is often a basic requirement for transmission performance in various types of mechanical equipment.
Spiral bevel gears are reliable and have a long lifespan.
Curved bevel gears are widely used in aviation, marine, and automotive industries due to their high load carrying capacity, low noise, and smooth transmission.
