What is the choice criteria for choosing a equipment reducer?
Before buying a gear reducer, it’s vital that you take several factors into consideration.
A equipment reducer is utilized to adapt the characteristics (torque and rate) of the input and output axis of a mechanism. This is 
why you have to know the torque and rotation speed.
It is therefore appropriate to consider about the torque first and foremost. A reducer escalates the torque of your motor and thus allows a receiving member to rotate under the impact of a fresh torque. Gear reducer manufacturers sometimes indicate the minimal and optimum 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 example, planetary gearboxes have a higher torque density.
The other reason for a gear reducer is to reduce the motor speed and we recommend that you take into account the ideal reduction ratio to use. Based on the rotational quickness of your electric motor, the reduction ratio is used to determine the output rotational rate. This information is also indicated by manufacturers on the product pages. It is given in revolutions per minute.
Lastly, you should consider the type of gear reducer assembly is most appropriate for your application. The gear reducer china insight and result shafts of your equipment reducer could be coaxial, parallel-shaft or orthogonal. This depends on your intended use.
