The main function of the speed reducer is to adjust the input and output speed through the reduction ratio, so as to achieve the required mechanical working speed. Since the speed reducer usually needs to run for a long time, during this process, due to factors such as friction and load, the temperature inside the speed reducer will gradually rise, which not only affects its working efficiency, but also may cause damage or premature wear of the equipment. Therefore, an effective cooling system is crucial to prolong the service life of the speed reducer and ensure its long-term stable operation.
