A bevel gear is a toothed mechanical component that transmits power between intersecting shafts, typically at a 90-degree angle, with conical-shaped teeth for efficient torque transfer.

Straight bevel gears have straight teeth that converge at the apex, offering simplicity and lower cost but higher noise and vibration. Spiral bevel gears have curved, helical teeth that engage gradually, providing smoother operation, higher load capacity, and reduced noise, making them suitable for high-speed applications.
The gear ratio is calculated as the number of teeth on the driven gear divided by the number of teeth on the driving gear. For example, if the driving gear has 20 teeth and the driven gear has 40 teeth, the ratio is 2:1, meaning the driven gear rotates at half the speed but with double the torque.
Regular maintenance includes lubrication with appropriate gear oil, inspection for wear, pitting, or misalignment, checking backlash and tooth contact patterns, and ensuring proper mounting and alignment to prevent premature failure.
