Gear unit – mechanism, transferring and modifying torque, with one or more mechanical transmissions. Gear unit main characteristics: performance index, gear ratio, transmission capacity, maximum angular rate of shafts, quantity of primary shafts and driven shafts, type and quantity of gears and stages.

Gear unit type is defined by gears content, arrangement order in direction from primary – high-speed shaft to driven output shaft and position of wheels. Gear units are classified by the following main features:
1) as per type of gear – toothed, worm, toothed-worm;
2) as per number of stages – single-reduction, double-reduction etc;
3) as per tooth wheel type – cylindrical, conical, conical-cylindrical etc;
4) as per relative location of shafts – horizontal, vertical.

Design of gear unit is defined by gear ratio, shapes of ends of shafts and assembly version.
