After years of trial and error, the industry has summarized some performance standards for evaluating the quality of WPWED40-70,WPWED50-80,WPWED60-100,WPWED70-120,WPWED80-135 reducers. Especially in the process of developing reducers, the most common problems are those that arise. Therefore, next time a reducer manufacturer comes to your door, first ask if you have encountered the problems mentioned below and to what extent they can be solved. This will give you a rough idea of whether this reducer manufacturer can be trusted.
1. Gearbox oil leakage
No matter what gearbox, oil leakage has always been a problem that all gearboxes should face. The reasons for oil leakage are also numerous and complex. If possible, it is best to directly ask the manufacturer for the specific reasons
2. Gear reducer accuracy
Most gear reducer manufacturers use professional equipment to measure the accuracy of angular transmission. Of course, customers can also design some simple and effective methods to measure, and the measurement of repeated positioning accuracy is the same as that of angular transmission accuracy.
For a new gearbox, achieving high repeatability positioning accuracy is not a problem for most manufacturers, but the biggest issue is consistency and stability. Most manufacturers initially meet the accuracy standards, but over time, the accuracy either becomes high, low, or simply deteriorates. So how to maintain the standard accuracy of the reducer for a long time becomes the reliability of distinguishing manufacturers.
3. Gearbox heating
This is a relatively intuitive but less focused point, and many may not know that the actual heating of the gearbox is partly due to its accuracy. The accuracy of a gearbox mainly depends on the degree of gear engagement. If the clearance between the teeth is larger, the accuracy of the gearbox will be worse. However, if a slight interference method is used, the accuracy can be improved. However, one disadvantage is that it can cause the body to heat up.
4. The lifespan of the gearbox
In fact, the lifespan of a gearbox mainly depends on the lifespan of the bearings. Generally speaking, the bearings in a gearbox are the easiest and the first to fail. Therefore, the longer the lifespan of the bearings in a gearbox, the longer the lifespan of the gearbox. In fact, in the harmonic industry, bearings have a certain probability of premature wear, which has been confirmed by major manufacturers and cannot be detected in the early stage. At this point, it is unclear whether there is a problem with the gearbox itself or with the customer. If you want to ask the manufacturer about the probability of wear and tear, they may not be able to answer it directly, or they may not dare to answer you directly. Moreover, there are differences in this probability between different brands, so everyone must be cautious.
5. Transmission efficiency of the gearbox
In fact, this is somewhat related to the precision, heat generation, and other factors mentioned above. Transmission efficiency is also one of the important evaluation criteria for reducers. It is generally difficult to measure specific data on transmission efficiency by oneself, and professional equipment is also needed to measure it.
The above are the five main issues that have been sorted out, because manufacturers generally refuse to disclose their specific issues, or some manufacturers do not even understand them themselves. However, if the above issues can be explained clearly to manufacturers, they will definitely belong to more reliable manufacturers.
