China Drive Chain Wholesaler introduces the repair process of sprocket:
1.Equipment damage condition: the equipment drive sprocket and the main shaft adopt the interference and flat key coupling connection type. During operation, due to changes in the limestone stockpile, the operating load exceeds the rated load. The long-term overload operation causes the clearance between the keyway and the key, the shaft and the sprocket hole to exceed the standard, which in turn causes the shaft diameter to be deformed and the sprocket set bearing installation and chain Wear of the matching parts of the wheels.
2.Repair process: Due to the particularity of the worn parts and the large amount of wear, traditional repair methods such as welding repair, brush plating and spraying cannot be used, and extensive research and careful consideration have been carried out.
After the plan is determined, repair the spindle sprocket and bearing installation parts in the machining workshop. First, perform the pre-processing treatment of the repaired parts, in which the processing depth of the sprocket mounting part is 0.80mm, and the processing depth of the bearing mounting part is 0.55mm; after cleaning the above-mentioned parts with absolute ethanol, the 2211F material is blended for coating repair. Use iodine tungsten lamp to heat for 4 hours to cure, normal temperature to cure for 12 hours
After that, the machine is repaired, and the feed amount of each turning is 0.01 ~ 0.02mm. During the second turning process, the repair material and the metal surface appeared bulging and falling off.
Through the above introduction, Roller Chains Exporter hopes that you can simply refer to the content of this article in future use.
