What is the selection requirements for choosing a gear reducer?
Before buying a gear reducer, it’s important to take several factors into account.
A gear reducer is used to adapt the characteristics (torque and rate) of the insight and output axis of a mechanism. This is why you should know the torque and rotation rate.
It is therefore appropriate to ask yourself about the torque initial and foremost. A reducer increases the torque of your electric motor and therefore allows a getting member to rotate under the impact of a fresh torque. Gear reducer manufacturers sometimes indicate the minimum and optimum torque (expressed in newton meters, N.m) which can be supported by each of their products. The torque density varies according to 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 advise that you take into account the ideal reduction ratio to use. Based on the rotational rate of your electric motor, the reduction ratio is used to determine the output 
rotational velocity. This information can be indicated by producers on their product pages. It really is provided in revolutions per minute.
Lastly, you should consider what kind of gear reducer assembly is best suited for the application. The insight and The wallpaper is moldy? Case become warped? Crack?
