Have to say how to check the maintenance and replacement gear oil
Date:2016-08-13 16:29 Hits:554

Starting gear oil, I think the first thing you all remember is probably the automobile transmission oil or the gear oil of the rear axle of the vehicle. In fact, gear oil is not only used in the automotive field, we also need gear oil. So, which parts of the excavator need gear oil? How can we check and change gear oil?

What is gear oil?

Can be understood literally, gear oil is certainly used for running gear meshing parts for excavator, need daily inspection and replacement of parts of gear oil is rotary motor reducer and walking motor reducer.

We do daily maintenance of the excavator, the most concern is probably the hydraulic oil and the oil, the hydraulic oil and oil no ground for blame, because of the lack or is the effect of modification on mining is fatal, can make the engine cylinder, pump premature wear, while in the engine and pump scrap. Then, the lack of gear oil or deterioration will have any impact on excavator?

What's the damage to gear oil?

What is the most afraid of the reducer? The most afraid of is that between the imperceptibly gear oil leakage, oil after it is easy to damage the bearings and gears, serious can put the whole gearbox scrapped, not only the loss of money, but also wasted time.

What are the causes of the oil leakage in the walking motor reducer?

Especially the walking motor reducer, because exposed to the outside, in some harsh construction environment, it is easy to damage the floating oil seal, thus leading to oil leakage. There are a lot of excavator is engaged in demolition operations or new real estate operations, this kind of site waste steel and scrap wire is particularly much, no one will be involved in the oil, after the floating throttle open hole, gear oil is easy to leak, and this kind of site debris more likely, wire involved in the reducer or has caused oil spills are not found.

If it is found in time, replace the floating oil seal and supplement gear oil, and if the oil leaks out, the gear, gear, gear, and gear will be damaged due to lack of lubrication.

How do I check if gear oil is missing?

The rotary motor reducer, a rotary motor oil scale generally above the daily check can be pulled out to observe the oil level gauge gear oil level is between the scale in the bottom two observation hole, the bottom of the scale represent the lowest level above the hole hole, represents the highest level of gear oil level is normal in between two observation holes. When the liquid level is lower than the lower hole, the gear oil should be added in time.

The reducer motor running, because there is no oil dipstick for daily inspection, so after the replacement of gear oil should closely observe whether there is oil leakage, oil is found when the timely replacement of oil seal and add gear oil check.

How do I change gear oil?

For the rotary motor reducer, when the gear oil change period is reached, replace the new gear oil in time. Oil change time can choose to stop working in the excavator after half an hour, when the gear oil is not in the bottom of reducer and oil temperature not too high too low, as far as possible to drain the old oil, the old oil discharged after tighten the drain screw, and then from the gear oil filler filling new gear oil, this time to pay attention observe the vernier, avoid too little or excessive add gear oil.

For the walking motor reducer, also change the gear oil in time according to the oil change cycle. In addition to oil, the traveling reducer without oil scale for daily inspection of oil, usually have to pay extra attention to walking oil leakage reducer, found oil leakage or leakage phenomenon, to gear oil added in time. Then, how to fill and replace gear oil for the walking motor reducer?

Filling or replacement of gear oil should be selected in the excavator to stop working for about half an hour after the temperature down again in the parking lot before the operation, can turn a single drive wheel to walk, for refueling location (usually the drive wheels have English logo, the English stop is on the line).

The next step is to put the oil, because the oil may not completely down, there is high temperature and high pressure reducer internal gear oil, unscrew the most directly at the lower end of the oil drain bolt may cause oil injection from danger, so in the oil can be from top to bottom, unscrew the three bolts of this operation more conducive to safe and clean old oil discharge.

Before you unscrew the bottom oil release bolt, you can use the basin and other containers to supply oil under the gear reducer. The old oil can be sold to the old oil recycling organization, and it will not pollute the environment.

After finishing the old oil, tighten the bottom oil drain bolt, and refuel from the top gear oil filling hole. For big dig, you can dig a hole in the middle of the mineral water bottle for filling.
