gear reducer

What is the selection criteria for choosing a gear reducer?

Before investing in a gear reducer, it’s important to take several factors into consideration.

A equipment reducer is used to adapt the characteristics (gear reducer torque and swiftness) of the input and output axis of a system. This is why you should know the torque and rotation velocity.

It is therefore appropriate to consider about the torque initial and foremost. A reducer escalates the torque of your engine and therefore allows a receiving member to rotate beneath the impact of a new torque. Gear reducer producers sometimes indicate the minimum and optimum torque (expressed in newton meters, N.m) that can be supported by each of their products. The torque density varies according to the gear reducer. For instance, planetary gearboxes have a higher torque density.

The other purpose of a gear reducer is to lessen the motor speed and we advise that you look at the ideal reduction ratio to use. Based on the rotational acceleration of your electric motor, the decrease ratio is used to look for the output rotational rate. This information is also indicated by producers on the product pages. It really is provided in revolutions per minute.

Lastly, you should ask yourself the type of gear reducer assembly is best suited for your application. The input and output shafts of your equipment reducer can be coaxial, parallel-shaft or orthogonal. This depends on your intended use.
