Working Principle

The working principle of 90-degree bevel gears involves the transfer of rotational motion between two intersecting shafts positioned at a right angle. These gears have conical-shaped teeth that mesh together to transmit torque and rotation. When one gear is driven, the teeth of the driving gear mesh with the teeth of the driven gear, causing the driven gear to rotate. The conical shape of the gear teeth allows for smooth and efficient power transfer. The angle of the teeth determines the gear ratio, and the size and number of teeth on each gear affect the speed and torque output. The precise engagement of the gear teeth ensures accurate and reliable motion transmission.
