3. Do bevel gearboxes have self-locking?

A bevel gearbox consists of a bevel gear and a bevel pinion. The axes are often offset by 90°, other angles are possible. These bevel gearboxes are used where high reduction ratios, torques and movements are required. They are usually driven via the bevel pinion, and left and right directions of rotation are possible. The transmission ratio is the quotient of the number of teeth z2 of the bevel gear by the number of teeth z1 of the bevel pinion. Self-locking as in a worm gear does not occur. Bevel gearboxes are used as power gearboxes in presses, rolling mills, machine tool construction, baggage conveyors, piece goods conveyors, cable lifters, storage technology, travelling drives, mixers and in automation, wherever movements and forces are transmitted at an angle.
