aper leading system is an important part of paper making equipment, which is composed of leading rope, leading rope wheel and driving device. It mainly plays the role of leading paper and passing paper strip to the next working area, and it is an important system affecting the output of paper machine
The problem of bearing position wear occurs during the operation of the dryer paper guide wheel of an enterprise. The axis of the paper guide wheel moves outward during operation, but the paper guide rope is stuck between the paper guide wheel and the dryer shaft, resulting in the failure of the paper guide system. The axle diameter is 300mm, the unilateral wear is 2.5-3mm, and the bearing 61860 (double disk).
According to past experience, many equipment managers will choose to repair the metal gasket after the bearing bit of the dryer lead wheel is worn, which requires adding appropriate copper metal gasket according to the bearing bit wear for emergency operation, which is more convenient to operate, but when the copper gasket is subjected to heavy load impact, it will deform or deviate from the position and affect the concentricity, thus aggravating the vibration of the equipment.
This method can only be used as a short-term emergency measure. There are many equipment managers will choose to replace the new parts for repair, which requires the replacement of the problem shaft according to the downtime of the parts, the storage situation and the value of the parts, which is not only time-consuming and laborious in disassembly, but more importantly, it needs to do a large number of inventory spare parts, occupying a large amount of enterprise capital flow.
Considering the repair cycle and the use effect after repair, Xiaobian suggests that the Solay technology is used to repair the bearing position of the dryer paper wheel after wear. The technology can be quickly repaired online, reduce or avoid disassembly, greatly shorten the downtime of enterprises, reduce the loss caused by sudden or major equipment problems; This technology is not an emergency treatment technology. Through the excellent performance of the material and the targeted repair process, the repaired surface and the bearing inside can reach the original mating surface, and at the same time, the interference size of the original design of the shaft can be restored, so that better forces can be ensured. Under the condition of proper lubrication and maintenance of the bearing and no ablation of the bearing, Its service life can reach or even exceed the service life of new parts.
