What does the reduction ratio of the geared motor mean?
The reduction ratio of the reduction motor refers to the ratio of the rotation speed between the reduction device (such as planetary gears, worm gears, cylindrical gears, etc.) and the rotor on the output shaft of the motor (usually the rotor on the motor). The reduction ratio can be calculated by the following formula: reduction ratio = output shaft speed/input shaft speed where the output shaft speed refers to the output shaft speed after the reduction of the speed reduction device speed, and the input shaft speed refers to the speed of the motor itself.
The reduction ratio is used to describe the speed change of the reduction gear to the motor output. Since the motor will generally output at a higher speed, in some applications a lower speed is required to meet the demand. At this time, the reduction motor plays a role, and the speed of the output shaft is reduced through the reduction device to provide an appropriate speed. On the one hand, the selection of the reduction ratio needs to be based on the requirements of practical applications, and on the other hand, the design and manufacturing costs of the reduction motor need to be considered. In general, the reduction ratio of the geared motor can be determined according to the ratio of the required speed and torque. If the output of high torque and low speed is required, the reduction ratio needs to be larger; and if the output of high speed and low torque is required, the reduction ratio can be relatively small. The choice of reduction ratio should also consider the impact on the overall performance of the geared motor. The larger the reduction ratio, the overall size and weight will usually increase, and it may also have a certain impact on the efficiency of the geared motor. Therefore, it is necessary to comprehensively consider the power demand, size limitation, weight requirement and efficiency when selecting the reduction ratio.
The reduction ratio of the reduction motor is generally determined by the gear ratio of the gear or worm gear inside the reduction device. For example, if there are 10 times more gears on the output shaft of the reduction gear than on the input shaft, then the reduction ratio is 10. Under normal circumstances, the reduction ratio is a fixed value, but in some special cases, some reduction motors can also be adjusted as needed to provide different reduction ratios. The choice of reduction ratio is of great significance to the application field of the geared motor. Gear motors are widely used in various mechanical equipment, such as machine tools, conveyors, printing machines, wind turbines, etc. Different application areas have different requirements for the reduction ratio. Some applications require a larger reduction ratio to provide more torque, while some applications require a smaller reduction ratio to provide higher speeds.
In addition to the reduction ratio, the geared motor has other important performance parameters, such as rated speed, rated power, rated torque, etc. These parameters also need to be considered when selecting the gear motor. Only by fully understanding and reasonably selecting the reduction ratio and other performance parameters can we ensure that the geared motor can work normally under specific application conditions and meet the needs of users. In short, the reduction ratio of the geared motor refers to the ratio of the rotation speed between the reduction device and the rotor on the output shaft of the motor. The choice of reduction ratio needs to be considered according to the application requirements and the impact on the overall performance of the geared motor. The reduction ratio of a geared motor is one of the important parameters that affect its output speed and torque, which is of great significance to the operation and performance of various mechanical equipment.
