How to judge whether the loader differential is damaged

[DIG-DOG]

Loaders play a key role in engineering operations, but if the loader differential is damaged, the problem becomes difficult. The operating environment of the loader is complex and the conditions are harsh. If the differential damage is not discovered in time, it will not only reduce work efficiency, but also cause safety hazards. This is indeed a vexing problem. So, how can we judge whether the differential is damaged? Next, I will introduce it to you in detail.

When driving the loader, be sure to pay attention to whether there is any abnormal noise coming from the rear axle. For example, the "clang clang" sound is quite suspicious. If this sound disappears after the neutral gear is engaged, it may mean that the differential gear is damaged or the connecting bolt is broken. A driver named Li encountered this situation when operating at the construction site. At first, he planned to continue working, but soon found that the loader became unusually strenuous. Therefore, once you hear this abnormal sound, you must stop immediately. Remember, do not blindly check and repair by yourself, but seek professional rescue. Replace the damaged parts after checking and confirming safety. When the loader is working normally, the noise should be stable and normal. If a new abnormal sound suddenly appears, it is a dangerous signal.

Many examples show that abnormal sounds from the loader differential often indicate a possible serious fault. Although some drivers noticed the sound, they delayed the inspection, and the differential was eventually completely damaged. This not only delayed the progress of the project, but also greatly increased the maintenance costs.

If you hear a roar similar to that of an airplane engine when the loader is operating, it is likely due to the wear of the main and passive teeth. Xiao Zhang encountered this situation when he was operating. At first, he didn't know what happened, but after a few days, the power of the loader was significantly reduced. Once this sound is found, it cannot be ignored and must be repaired as soon as possible. This sound is mainly caused by the wear of the main and passive teeth. During maintenance, only the worn parts need to be replaced and the loader can resume normal operation. At the construction site, we must be alert to the sound of the loader and must not let this seemingly small problem turn into a big trouble.

If the equipment management personnel ignore such sounds, the loader may suddenly fail in subsequent operations, resulting in downtime. This is extremely detrimental to the ongoing project.

When the loader accelerates, if you hear a regular "knocking" sound, it is likely that the gear clearance inside the differential is too large. Wang Wu encountered such a problem when he was driving a loader. He slowed down immediately after hearing the sound and sent the loader to the after-sales service center. To deal with this kind of problem, the main thing is to check and repair the gear clearance. Usually, a slight adjustment or replacement of severely worn gears can solve the problem. If this knocking sound is ignored, the gear clearance will become larger and larger, causing the gear damage to increase, and eventually the differential may not operate normally.

Under various working conditions, the differential of the loader may encounter such problems. This phenomenon is more common in heavy load acceleration or frequent start and stop operations.

When the loader is driving or working at a low speed, you may wish to pay attention to the operation of the differential. If you feel that the loader seems to be struggling, and there is no obvious problem with the engine power, it is likely that there is a problem with the differential. For example, on a construction site, a loader was carrying stone and there was a noticeable jam at a slow speed. After eliminating possible problems such as the engine, it was finally found that the differential was faulty. At this time, it is necessary to carefully check whether the internal parts of the differential are worn or aged. Once a problem is found, it is necessary to repair or replace it in time, otherwise the working efficiency of the loader will be greatly reduced.

Problems that are easy to appear when driving at low speed are often ignored by operators, mainly because their attention is mostly focused on the condition of the loader when driving at high speed or under heavy load.

In addition to judging details such as sound, we can also feel the temperature of the differential by touch. After the loader has been operating for a period of time, you can touch its outer shell lightly, but be careful not to get burned. If the outer shell temperature is abnormally high, far exceeding the normal working temperature, it may be due to excessive friction inside the differential. This may be due to insufficient lubricating oil or a problem with the operation of an internal component. When Lao Zhao was operating the loader, he encountered abnormal heating of the differential. He immediately called the maintenance personnel and found that it was caused by insufficient lubricating oil. From this, it can be seen that in daily work, it is also very important to pay attention to the heating condition of the differential.

When the differential is operating normally, the temperature will rise, which is normal. However, if the temperature is too high, the cause must be found out immediately, otherwise the differential may suffer serious damage.

When the loader turns, it is the time to check whether there is a problem with the differential. In theory, the steering of the loader should be smooth and stable. However, if it feels laborious when turning, or accompanied by abnormal shaking, it is likely that there is a problem with the differential. Take the loader on the mine as an example. It always seems not smooth enough when turning. After inspection, it was found that the planetary gear of the differential was damaged. Therefore, when the loader turns abnormally, do not ignore the possible faults of the differential, and check and inspect it immediately.

Operating the steering of the loader is a routine operation, but if an abnormality occurs at this time, it may interfere with the efficiency of the operation process, and even cause a safety accident in serious cases.
