Lastly, you should ask yourself the type of gear reducer assembly is most appropriate for the application. The insight and output shafts of your gear reducer can be coaxial, parallel-shaft or orthogonal. This depends upon your intended use.
The other purpose of a gear reducer is to lessen the motor speed 
and we recommend that you look at the ideal reduction ratio for your use. Predicated on the rotational velocity of your electric motor, the decrease ratio is used to look for the output rotational speed. This information can be indicated by manufacturers on the product pages. It is given in revolutions per minute.
Hence, it is appropriate to ask yourself about the torque 1st and foremost. A reducer escalates the torque of your electric motor and therefore allows a getting member to rotate beneath the impact of a new torque. Gear reducer producers sometimes indicate the minimum and maximum torque (expressed in newton meters, N.m) which can be supported by each of their items. The torque density varies according to the gear reducer. For instance, planetary gearboxes possess a high torque density.
A equipment reducer is utilized to adapt the characteristics (torque and rate) of the input and output axis of a system. This is why you should know the torque and rotation rate.
Before buying a gear reducer, it’s important to take several factors into account.
