How To Choose Reducer Gear

　　A Reducer Gear is a mechanical transmission that connects a motor to the load being driven. It is also called a gearbox. It allows you to modify the torque and speed between the motor and the load. The reduction gear assembly consists of a series of gears. The gear reduction ratio (the ratio of the number of teeth between the input shaft and the output shaft) is also called the transmission ratio.

　　Before purchasing Reducer Gear, it is important to consider several factors. The Reducer Gear is used to adapt the characteristics (torque and speed) of the input and output shafts of the mechanism. That's why you must know torque and rpm.

　　So it's fitting to ask yourself a question about torque first. The reducer increases the torque of the motor, allowing the receiving part to spin under the onslaught of the new torque. Reducer Gear manufacturers sometimes state the minimum and maximum torque (expressed in Newton meters, Nm) that each of their products can support. Torque density varies according to Reducer Gear. For example, planetary gearboxes have a high torque density.

　　Another use of the Reducer Gear is to reduce the speed of the motor, we recommend that you consider the ideal reduction ratio when using it. According to the speed of the motor, the reduction ratio is used to determine the output speed. This information is also indicated by the manufacturer on its product page. It is given in revolutions per minute.

　　Finally, you should ask yourself which Reducer Gear assembly is best for your application. The input and output axes of the Reducer Gear can be coaxial, parallel, or orthogonal. It depends on your intended use.
