What 
is the choice requirements 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 characteristics (torque and rate) of the input and output axis of a mechanism. This is why you have to know the torque and rotation acceleration.
It is therefore appropriate to ask yourself about the torque first 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 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 based on the gear reducer. For example, planetary gearboxes have a high torque density.
The other reason for a gear reducer is to reduce the motor speed and we recommend that you look at the ideal reduction ratio for your use. Based on the rotational quickness of your engine, the decrease ratio is used to look for the output rotational acceleration. This information can be indicated by gear reducer china manufacturers on their product pages. It is given in revolutions per minute.
Lastly, you should ask yourself the type of gear reducer assembly is best suited 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.
