What is a Bevel Gear and How does it Work? - Linquip

The key advantage of a bevel gear over a worm gear used for the best angle transmission is the efficiency of the system. Worm gears are commonly only around 50-80% efficient, so 20-50% of the energy is wasted within the right angle system. Bevel gearboxes, however, can be efficient up to 98% – with just a tiny waste of energy from input to ...
