Separating bearings of internal combustion forklift clutches work frequently, and the number of damages accounts for a large proportion of forklift failures. If the driver is properly operated and maintained in a timely manner, the bearing can be used for about 3 months, but it must be replaced when it is repaired. If the driver's technical level is low, the forklift that is driven will have damage to the separation bearing almost every month. After the damage, other parts will be removed, such as the separation lever and the clutch plate, so that the material cost of equipment maintenance is obviously improved.
In response to the above problems, it has also been tried to heat the bearing in the grease to allow the grease to penetrate into the bearing. After the treatment, the grease can fill the bearing, but the grease is destroyed due to the high temperature treatment. The amplitude is reduced, the effect of using this method is not ideal, and the service life of the bearing is not extended. We also used a sharp-mouthed grease gun to directly grease the release bearing. After installing the vehicle, the service life of the bearing is greatly extended after observation and inspection. This method of oiling has received satisfactory results, but the operation is more complicated. Then I explored the case where the engine was not disassembled, and the butter was added. Firstly, the test was successful on the 475 C engine, and then the 475C and 480 and 492 engines were tried. Both of them received good results. After repeated practice, improvement, and summing up experience, a relatively simple method of oil injection operation was finally formed. The specific process is as follows:
(l) The engine does not disintegrate the oil filling method. First open the clutch cover to check the wear of the separated bearing. If it is confirmed that the bearing is not damaged or the wear is not over the limit, remove the clutch pedal, adjust the connecting rod pin, and make the separation bearing and its Return the seat to the last position, fill the hole of the bearing housing with a grease gun until the bearing overflows, then turn the bearing slightly, refill the oil, repeat the above work until there is a little butter around the bearing, then Rotate the bearing and observe the amount of oil. If there is resistance to the rotation of the bearing, it is proved that the bearing is filled with butter. Then remove a small amount of butter from the separation housing and reassemble the removed pin and clutch cover.
(2) Oil filling method of engine disintegration The engine is disassembled to expose the assembly of the separation bearing and the bearing housing, and the grease hole is used to refuel the small oil hole below the inner ring of the separation bearing housing. When the bearing has butter overflow, the bearing is rotated until the bearing one The ring can be filled with butter. After the above two methods are processed, the bearings can be removed without oiling within half a year. After the trial of the oil filling method at Hengshui Railway Station, the mechanical integrity rate was significantly improved and significant economic benefits were achieved. It can save material costs; increase the loading and unloading volume, and increase the loading and unloading capacity by 30t per month. This method has also been promoted at other railway stations and has achieved satisfactory results.
