What is the selection criteria for choosing a gear reducer?
Before buying a gear reducer, it's important to take several factors into account.
A equipment reducer can be used to adapt the features (torque and acceleration) of the insight and result axis of a mechanism. This is why you have to know the torque and rotation velocity.
It is therefore appropriate to gear reducer china consider about the torque initial and foremost. A reducer escalates the torque of your engine and thus allows a receiving member to rotate beneath the impact of a new torque. Gear reducer manufacturers sometimes indicate the minimum and maximum torque (expressed in newton meters, N.m) that can be supported by each of their products. The torque density varies based on the gear reducer. For instance, planetary gearboxes have a high torque density.
The other reason for a gear reducer is to reduce the motor speed and we advise that you take into account the ideal reduction ratio to use. Based on the rotational acceleration of your motor, the reduction ratio is used to determine the output rotational rate. This information is also indicated by producers on their product pages. It is provided in revolutions each and every minute.
Lastly, you should 
consider what kind of gear reducer assembly is most appropriate for the application. The insight and result shafts of your gear reducer can be coaxial, parallel-shaft or orthogonal. This depends upon your intended use.
