3. Do bevel gears have a self-locking mechanism?

A bevel gear consists of a bevel gear and a bevel pinion. The axes are often offset by 90°, other angles are possible. Areas of application for these angular gearboxes are where high reduction ratios, torques and movements are required. The drive is usually via the bevel pinion; left and right directions of rotation are possible. The gear ratio is the quotient of the number of teeth z2 on the bevel gear by the number of teeth z1 on the bevel pinion. There is no self-locking like with a worm gear. Bevel gears are used as power transmissions in presses, rolling mills, machine tool construction, baggage conveyors, piece goods conveyors, cable lifts, storage systems, travel drives, mixers and in automation, wherever movements and forces are transmitted at an angle.
