Rate reducers are mechanical products that help drive systems maintain optimal acceleration and torque for the application form. Also known as gearboxes and gear drives, they lower the swiftness of rotation of the insight shaft by a particular ratio and boost the power transmitted to the result shaft by the same ratio. Ratio multipliers increase the speed decrease and torque supplied by a rate reducer by a particular ratio and are suitable for parallel setups. Mounting bases, torque arms, and flange couplings are accessories used with rate reducers. They are generally used in applications where the speed reducer will never be directly attached to the drive mechanism.

Many gearbox designs allow for the electric motor to be directly mounted to the reducer. These designs incorporate either extremely specific flanges to allow the motor to be directly connected to the reducer or other adapters with essential couplings. This eliminates the need for separate mounting of the engine, but is normally only practical with smaller motors.

Integrating Speed Reducers
After selection, the next issue is the way the gearbox will be integrated into the machine. Always check the way the gearbox will become mounted and how it’ll be connected to the driver and driven load because it may differ from machine to machine.

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