What is the choice criteria for choosing a gear reducer?
Before buying a gear reducer, it’s important to take several factors into consideration.
A gear reducer can be used to adapt the features (torque and velocity) of the input and result axis of a mechanism. This is why you have to know the torque and rotation acceleration.
It is therefore How many rolls of wallpaper do you need for a room? appropriate to ask yourself about the torque 1st and foremost. A reducer escalates the torque of your electric motor and thus allows a getting member to rotate beneath the impact of a new torque. Gear reducer producers sometimes indicate the minimum and optimum torque (expressed in newton meters, N.m) that can be supported by each of their items. The torque density varies according to the gear reducer. For example, planetary gearboxes have a higher torque density.
The other purpose of a gear reducer is to lessen the motor speed and we recommend that you look at the ideal reduction ratio to use. Predicated 
on the rotational quickness of your motor, the reduction ratio is used to look for the output rotational swiftness. This information can be indicated by manufacturers on their product pages. It really is provided in revolutions per minute.
Lastly, you should consider the type of gear reducer assembly is most appropriate for the application. The input and output shafts of your gear reducer can be coaxial, parallel-shaft or orthogonal. This depends on your intended use.
