The meaning of the gearbox nameplate

Through observation, we have found that many users request the manufacturer to provide the nameplate of the equipment when purchasing a gearbox. So what is the reason for doing this, and what do these nameplates mean? In order to help everyone solve their doubts, the editor specifically inquired with relevant manufacturers and professional technicians. Now, the editor will share with you the compiled information:
Usually, the nameplate of a gearbox mainly indicates the mechanical model, serial number, and even information such as reduction ratio, working life, return clearance, full load efficiency, and rated torque. The nameplate is like a work permit for our staff, detailing all information about the equipment. Therefore, when purchasing, we can often understand the specific characteristics of the equipment through the nameplate, such as the following:

1. Full load efficiency: The mechanical transmission efficiency under high load conditions (when the output torque stops due to a fault).
2. Reduction ratio: The ratio of the input speed to the output speed of a reducer.
3. Rated torque: It is the torque that the reducer can operate for a long time within its rated life.
4. Working life: The cumulative working time of the equipment at rated input speed under rated load.
5. Return clearance: Fix the input end and rotate the output end clockwise and counterclockwise. When the output end is subjected to plus or minus 2% of the rated torque, there will be a slight angular displacement at the output end of the reducer, which is the return clearance.
In summary, we can see that the parameters on the gearbox nameplate have specified values for our reference. Therefore, we should use them correctly according to the above parameters to avoid mechanical damage that may affect the effectiveness of use.
