The internal bearing of fork-lift truck clutch works frequently. The number of damages accounts for a large proportion of failures of forklifts. If the driver operates it properly and maintains it in time, this bearing can be used for about 3 months, but it must be replaced when repaired.
If the driver's technical level is low, the driven forklift will break the bearing every month almost every month, and will damage other components after the damage, such as the separation of levers and clutch plates, so that the material cost for equipment maintenance is significantly increased.
What is the reason for the damage of the clutch release bearing? In practice, although the driver was once strictly required to drip oil once a day to separate bearings, this operation was not only cumbersome, but also the bearings were often damaged. After analysis, because the engine's high temperature is transmitted to the separate bearings, coupled with high-speed rotation of the bearings also produce high temperatures, in this condition the oil is difficult to remain in the bearing, the bearing works continuously at high temperatures, and the lubrication conditions are not good, this is Frequent damage causes.
In response to the above problems, it has also been tested that the bearing is placed in the grease to heat the grease so that the grease penetrates into the bearing. After the treatment, although the grease can fill the bearing, the structure of the grease after high temperature treatment is damaged and the performance is high. Reduced amplitude, the use of this method is not ideal, the bearing life is not extended. We have also used butter guns to directly inject butter into the separate bearings. Then install the car, after inspection and inspection, the bearing life is greatly extended. This method of injection has received satisfactory results, but the operation is more complicated. Then, he explored how to add butter when the engine did not disintegrate. He first tried successfully on the 475c engine, and later on the 475c and 480, 492 engines. All received good results.
After repeated practice, improvement, and summing up experience, a relatively simple set of oil filling operation methods was finally formed. The specific process is as follows:
(l) Engine disintegration method First, open the clutch cover and observe the wear condition of the release bearing. If it is confirmed that the bearing is not damaged or the wear does not exceed the limit, remove the clutch pedal, adjust the connecting rod pin, and separate the bearing and its The seat is retracted to the final position. Grease the bore of the bearing housing with a sharp-nosed grease gun until the bearing oil has spilled. Then rotate the bearing a little and refill the oil. Repeat until the bearing has a little butter around it. Rotate the bearing and observe the amount of oil. If you feel the resistance of the bearing rotation, prove that the bearing has been filled with butter. Then remove a small amount of grease that has come out of the separate bearing housing and reassemble the removed pin and clutch cover.
(2) Disassembly of the engine by disassembly of the engine exposes the disassembled parts of the engine to the bearing and bearing assembly. Use a needle grease gun to refuel the small oil hole below the inner ring of the bearing housing. When the grease overflows, the bearing rotates until it reaches the bearing. All circles have butter overflow. After the above two methods are processed, the bearing can be no longer refueled within six months.
After this set of oil injection method was tested at the Hengshui Railway Station, the mechanical integrity rate was significantly improved and obvious economic benefits were achieved. The cost of materials can be saved; the amount of loading and unloading can be increased, and the load can be increased by 30 tons per month. This method has also been promoted at other railway stations and has achieved satisfactory results.
