Quickness reducers are mechanical devices that help drive systems maintain optimal speed and torque for the application. Also known as gearboxes and equipment drives, they lower the quickness of rotation of the input shaft by a certain ratio and increase the power transmitted to the result shaft by the same ratio. Ratio multipliers boost the speed reduction and torque supplied by a quickness reducer by a certain ratio and are suitable for parallel setups. Installation bases, torque arms, and flange couplings are components used with speed reducers. They are often used in applications where the speed reducer will never be directly mounted on the drive mechanism.

Many gearbox designs allow for the engine to be directly mounted to the reducer. These designs incorporate either extremely exact flanges to allow the motor to be directly connected to the reducer or additional adapters with integral couplings. This eliminates the need for individual mounting of the engine, but is usually only practical with smaller sized motors.

After selection, the next issue is how the gearbox will be built-into the machine. Always check how the gearbox will end up being mounted and how it’ll be connected to the driver and powered load because it may differ from machine to machine.

In some applications the quantity of backlash, transmission error, torsional rigidity, and second of inertia are also important. The amount of torque needed could very well be the most crucial criteria, as this translates to the quantity of work the speed reducer must perform.
