In terms of the selection of (reducers), Shanghai Dianmai Transmission provides you with the following suggestions:
First of all, reducers with a reduction ratio close to the ideal one should be selected as much as possible. The calculation method of the reduction ratio is: Reduction ratio = Rotational speed of the servo motor / Rotational speed of the output shaft of the reducer. The ideal reduction ratio can achieve more efficient transmission effect and improve the operating performance of the entire system.
Secondly, the calculation of torque is of crucial importance. For the service life of the reducer, accurate torque calculation is indispensable. It is necessary to pay attention to the maximum torque value of acceleration (TP) and confirm whether it exceeds the maximum load torque that the reducer can withstand. Because once the torque exceeds the load, it will not only affect the normal operation of the reducer, but also may significantly shorten its service life and even lead to equipment failure.
Furthermore, there are many precautions in the selection of reducer models. Generally, the applicable power refers to the applicable power of common servo models on the market. It is worth noting that the applicability of the reducer is quite wide, and the working coefficient can generally be stably maintained at more than 1.2. However, the specific selection can still be determined according to your actual needs. There are two key points:
A. The output shaft diameter of the selected servo motor must not be larger than the maximum usable shaft diameter specified in the table. If the shaft diameter is too large, it may lead to mismatch in installation and affect the normal connection and operation of the equipment.
B. If through torque calculation, the working speed can meet the requirements during normal operation, but is insufficient when the servo is in full output. At this time, we can perform current-limiting control on the driver on the motor side or set a torque protection device on the mechanical shaft. These two measures are very necessary for ensuring the stable operation and safety protection of the equipment.
Hope the above suggestions can help you make wiser and more accurate decisions when selecting reducers to ensure the efficient and stable operation of the equipment.
