1) Descriptions of Spiral Bevel Gear
The spiral bevel gear achieves power transmission by the mutual meshing of the spiral tooth profiles.
It converts the rotational motion of one shaft into the rotational motion of another intersecting shaft.
2) Features of Spiral Bevel Gear
a) Engagement method: It adopts a progressive engagement. The tooth surface contact gradually
transitions from one end of the tooth to the other.
b) Motion characteristics: During the engagement process, a large number of tooth pairs are involved and the overlap degree is high.
3) Advantages of Spiral Bevel Gear
a) Progressive meshing reduces shock and vibration, and significantly lowers operating noise.
b) High overlap degree enhances the bearing capacity of the gears, enabling them to transmit greater torque
and effectively improving the transmission efficiency.
