1) Description of Double-sided Spiral Bevel Gear
Double-sided spiral bevel gear is a special spiral bevel gear type, which has the features of spiral bevel gear and worm sets.
Double-sided spiral bevel gear is widely applied in the occasions where high torque and high precision transmission are required.
2) Features of Double- sided Spiral Bevel Gear
-
Hyperbolic Surface Design: The gear shafts, though not physically intersecting, are arranged in a spatially intersecting configuration. This design enhances the contact ratio of the gears, increases their load-bearing capacity, and improves transmission smoothness, thereby contributing to more efficient and reliable mechanical performance.
-
Spiral tooth profile: The tooth surface is distributed in a spiral manner. During operation, the gear can achieve progressive contact, effectively reducing impact force and noise levels. It is particularly suitable for high-speed transmission devices.
-
Double-sided meshing: The tooth surfaces of the small gear and the large gear mesh simultaneously on both sides, significantly improving the load balance and overall efficiency during the transmission process.
