Gearbox types at a glance
| Type | Shaft arrangement | Typical ratio per stage | Typical use |
|---|---|---|---|
| Worm | Right angle | About 5:1 to 100:1 | Conveyors, hoists, mixers, general duty |
| Helical inline | Coaxial / parallel | About 1.5:1 to 10:1 | Conveyors, pumps, fans, continuous duty |
| Bevel-helical | Right angle | Two or three stages | Conveyors, kilns, tight spaces |
| Planetary | Coaxial | About 3:1 to 10:1 | High torque in compact size, servo, mixers |
| Cycloidal | Coaxial | High ratios in one stage | Shock loads, robotics, heavy intermittent duty |
| Shaft mounted | Hollow output | Two or three stages | Screw and belt conveyors, agitators |
Typical single-stage ratios from general engineering practice. Exact ratios, torque and efficiency depend on the manufacturer and size.
