What does the reduction ratio of a geared motor mean?

Reduction ratio is an important parameter of a reduction motor, which refers to the speed ratio between the reduction device (such as planetary gears, worm gears, cylindrical gears, etc.) and the rotor on the output shaft of the motor. It can usually be calculated using the following formula:

Reduction ratio=output shaft speed/input shaft speed

Among them, the output shaft speed refers to the actual output speed reduced by the deceleration device, while the input shaft speed refers to the original speed of the motor itself.

Reduction ratio is used to describe the degree of change in motor output speed caused by a reduction device. Motors usually operate at higher speeds, but in some application scenarios, the output speed needs to be reduced to meet actual needs. At this point, the deceleration motor adjusts the output speed to the desired range through the built-in deceleration mechanism.

When choosing a reduction ratio, it is necessary to consider both the requirements of practical application conditions and the design complexity and manufacturing cost of the reduction motor. The reduction ratio can usually be determined based on the required output speed and torque. If high torque and low-speed output are required, a larger reduction ratio should be chosen; If a higher speed is required but the torque requirement is not high, a smaller reduction ratio can be chosen.

The choice of reduction ratio can also affect the overall performance of the reduction motor. Generally speaking, the larger the reduction ratio, the larger the overall size and weight of the motor, which may also have a certain impact on transmission efficiency. Therefore, when selecting, it is necessary to comprehensively consider factors such as power requirements, installation space, weight limitations, and energy efficiency requirements.

The specific value of the reduction ratio is usually determined by the gear ratio of the internal gears or worm gears of the reduction mechanism. For example, if the number of teeth on the output shaft gear is 10 times that of the input shaft gear, the reduction ratio is 10. The reduction ratio of most reduction motors is a fixed value, but in some special types of reduction motors, variable reduction ratios can also be achieved through structural adjustment.

The reasonable selection of reduction ratio is of great significance for the application field of reduction motors. This type of motor is widely used in various mechanical equipment, including machine tools, conveyor belts, printing machines, wind turbines, etc. Different application scenarios have different requirements for reduction ratio: some require a higher reduction ratio to provide greater torque, while others require a smaller reduction ratio to achieve higher speeds.

In addition to the reduction ratio, the reduction motor also has multiple other key performance parameters, such as rated speed, rated power, rated torque, etc. When selecting, it is also necessary to conduct a comprehensive evaluation of these parameters. Only by fully understanding the actual working conditions and selecting the appropriate reduction ratio and other performance indicators can we ensure the stable operation of the reduction motor in specific applications and meet the usage requirements.

In summary, the reduction ratio of a deceleration motor is an important indicator for measuring the relationship between its output speed and the original speed of the motor. The selection of reduction ratio should be based on specific application requirements and comprehensively consider its impact on the overall performance of the motor. This parameter directly affects the output speed and torque characteristics of the motor, and plays a key role in the operation of various mechanical equipment.
