What is the choice criteria for choosing a gear reducer?
Before buying a gear reducer, 
it’s important to take several factors into account.
A equipment reducer is utilized to adapt the characteristics (torque and quickness) of the insight and result axis of a mechanism. This is why you should know the torque and rotation quickness.
It is therefore appropriate to ask yourself about the torque initial and foremost. A reducer escalates the torque of your motor and therefore allows a receiving gear reducer china 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) that can be supported by each of their items. The torque density varies according to the gear reducer. For example, planetary gearboxes possess a high torque density.
The other purpose of a gear reducer is to reduce the motor speed and we recommend that you look at the ideal reduction ratio to use. Based on the rotational rate of your electric motor, the reduction ratio is used to look for the output rotational velocity. This information can be indicated by manufacturers on their product pages. It is provided in revolutions each and every minute.
Lastly, you should ask yourself what kind of gear reducer assembly is best suited for your application. The insight and result shafts of your equipment reducer could be coaxial, parallel-shaft or orthogonal. This depends on your intended use.
