The function of the rollers is to transfer the weight of the locomotive group to the ground and roll on the track. In order to prevent derailment, the rollers should also be able to prevent the track from moving relative to it laterally. The function is still very important, but in its use, there will also be some failures, such as the oil leakage of the roller, can it still be used? Let me introduce to you below.
The rollers carry the full weight of the excavator and are responsible for the driving function of the excavator. There are two main failure modes, one is oil leakage and the other is wear. The oil leakage of the roller wheel is a problem that almost all excavator masters have encountered. Many people ignore it and replace it with a new one when it is polished. Basically, the maintenance after oil leakage is replaced by a new one.
The lubrication of the walking system of construction machinery is very important. Many roller bearings have problems and the accessories fail because they have not been lubricated and maintained and have not been able to detect oil leakage in time. While doing a good job of lubrication, be sure to pay attention to whether there is oil leakage in the rollers. Of course, everything should be in moderation, and the lubrication of the rollers should not be excessive.
The roller shaft is constantly rotating through the shaft sleeve, and the wheel body needs to be lubricated with oil, but if the sealing ring is not good, it is easy to cause oil leakage, so the shaft and the shaft sleeve are easy to wear without lubrication. cause the product to be unusable.
The reasons for the oil leakage of the rollers are as follows: unqualified floating oil seal; insufficient roundness of the product shaft sleeve; insufficient gloss of the support shaft; substandard gear oil; machining dimensional tolerances and so on. All of the above problems will cause the oil leakage of the rollers.
Whether the oil leakage of the roller can still be used normally depends on the specific situation. Generally speaking, when we find the oil leakage of the roller, we need to first determine the cause of the failure, and then make corresponding actions according to the specific reasons. solutions.
Roller is an important part of the walking system of construction machinery, which is directly related to the walking performance and working performance of the equipment. Failure will inevitably lead to the failure of the machine to walk, and there is no way to continue working and delay the project. Therefore, you must pay more attention and not take it lightly. , the oil leakage phenomenon of the rollers cannot be ignored.
