What are the advantages of the combined reducer and how to calculate the reduction ratio?

Compared to a single-stage gearbox, a combined gearbox has the following advantages:
Larger reduction ratio range: Single stage reducers typically have a smaller reduction ratio range, while combination reducers can achieve a wider range of reduction ratios by combining different reducers to meet the needs of different application scenarios.
Higher transmission efficiency: Combination reducers usually use multi-stage parallel shafts or multi-stage coaxial structures, which can reduce the speed and torque of the gearbox during transmission, thereby improving transmission efficiency.
Greater output torque: The combination reducer adopts a multi-stage structure, which can achieve greater output torque by stacking the output torque, meeting some applications that require high torque transmission.
Higher accuracy and stability: The combination reducer adopts a multi-stage structure, which can reduce the errors and deviations of the single-stage reducer, thereby improving the accuracy and stability of the reducer.
More flexible structural design: Combination reducers can be combined with different structures according to actual application needs, thereby achieving more flexible structural design and application layout.
Therefore, combination reducers have advantages in areas that require larger reduction ratios, higher transmission efficiency, greater output torque, higher accuracy and stability, and more flexible structural design.
The reduction ratio of two combined reducers can be calculated using the following formula:
Reduction ratio=Reduction ratio of reducer 1 x Reduction ratio of reducer 2
Among them, reducer 1 and reducer 2 are two combined reducers, and their reduction ratios can be viewed in the product parameters.
It should be noted that in practical applications, due to factors such as friction, transmission errors, and loads, the actual reduction ratio may slightly deviate from the theoretical calculation value. Therefore, when selecting a reducer, it is necessary to consider the actual application situation reasonably and leave a certain margin to ensure the normal operation and service life of the reducer.
