Reducer Selection Tips How to choose the right reducer correctly?

There are various types of reducers, and we can divide them into many types based on their respective characteristics. And we usually don't know what kind of gearbox is suitable for us when we buy it, in order to avoid this situation and let everyone have a better understanding of the gearbox. Let me introduce to you how to choose a reducer?

1、 Select specifications based on mechanical power or torque (strength verification)

The biggest difference between the design and selection methods of universal reducers and specialized reducers is that the former is applicable to various industries, but the reducer can only be designed according to a specific operating condition. Therefore, when selecting, users need to consider different correction factors according to their own requirements. Factories should label the motor power (not the rated power of the reducer) according to the actual selection; The latter is designed according to the specific conditions of the user, and the coefficients to be considered are generally taken into account during design. When selecting, it is relatively simple to ensure that the power used is less than or equal to the rated power of the reducer.

2、 Thermal balance verification

The allowable thermal power value of a universal reducer is determined based on the maximum allowable equilibrium temperature of the lubricating oil (usually 85 ℃) under specific operating conditions (generally 20 ℃, 100% per hour, continuous operation, and 100% power utilization). When the conditions are different, correction is made according to the corresponding coefficient (sometimes combined into a single coefficient).

3、 Check the radial load borne by the shaft extension part

Universal reducers often require limitations on the maximum radial load allowed to be borne by the input and output shafts in the middle, which should be verified. If exceeded, requirements such as thicker shaft diameters and larger bearings should be proposed to the manufacturer.
