After years of testing, we have summed up some performance indicators for evaluating the quality of the reducer, especially where problems are prone to occur in the development process.No one can escape from these pits.Whether it can be solved and when it can be solved depends on the R&D strength.Therefore, the next time a reducer manufacturer comes to your door, you can ask them if they have encountered these problems, and to what extent they will know that this company is not reliable.
XNUMX. Oil spill
Regardless of the reducer, this is a problem to be faced.The cause of oil leakage is more complicated, involving oil seal brand, oil packaging, shaft processing technology, use method, etc., and oil leakage is divided into real oil leakage and fake oil leakage.
XNUMX. Precision
There are two types here, one is the angular transmission accuracy, which will be marked in the reducer manual, which affects the positioning accuracy of the robot; the other is the repeat positioning accuracy, which is not in the manual, which affects Repeated positioning accuracy of the robot.Angle transmission accuracy is generally provided by reducer manufacturers with professional equipment, but customers can also design some simple methods to measure them.The same is true for repeat positioning accuracy.
Three, fever
This is more intuitive, but a point that less people pay attention to.In fact, heating is also related to the accuracy mentioned above.The accuracy of the reducer depends on the meshing degree of the gears. If the meshing gap is too large, the accuracy will be poor. However, the accuracy will be improved if the micro-interference method is adopted, but it will cause the problem of excessive heat generation.
Fourth, life
The service life is also the point where the domestic reducer has been complained about.Everyone always complains about the short lifespan of the reducer, but there are not many people who can make it clear what the short lifespan is.In fact, the life is mainly determined by the life of the bearing. Generally speaking, the bearing is broken first, especially the harmonics. In the case of RV, the planetary structure is also vulnerable.
XNUMX. Transmission efficiency
In fact, this has something to do with the accuracy, heat generation, and grease mentioned earlier.Transmission efficiency is also one of the important evaluation indexes of reducer.To test the transmission efficiency also requires professional equipment, and it is difficult for customers to measure specific data by themselves.However, it is possible to make a horizontal comparison.Heat is an intuitive way of comparison. Junior high school knowledge tells us that energy is conserved. If the heat is larger, it means that more power of the motor is used to eliminate friction, and the output power will naturally be less.When the output power is less, the load capacity is naturally weak, the acceleration is naturally small, and the beat is naturally slow.
