Don’t You Understand How To Repair The Worn Bearing Position On The Transmission Side Of The Crusher?

Don’t you understand how to repair the worn bearing position on the transmission side of the crusher?

Is online repair reliable?

Once many companies hear about online repair, their first reaction is "Is this feasible?" The Henan company also hesitated at first. The eccentric shaft bearing of the jaw crusher in his factory is in extremely serious wear condition, and one day of downtime will cost tens of thousands of yuan. The traditional method is to dismantle it and transport it outside for welding and repair of the wear and tear of the eccentric shaft bearing of the jaw crusher. It takes two or three days to disassemble and transport it alone. After Sole Industrial engineers arrived at the site, it took only one day to properly handle the worn areas. After the equipment was reinstalled and started running, the vibration and temperature were in normal condition. It has been running for three months since the repair, without any problems.

What’s special about carbon nanopolymer materials

The core of this repair is the material. Carbon nanopolymer is not an ordinary metal. It does not have the problem of metal fatigue. The bearing position repaired with this material will have a longer life than the new shaft under normal maintenance. The repair does not require heating or welding, and will not change the material and structure of the shaft itself. The eccentric shaft of the crusher in Henan was repaired twice by riveting welding, and it began to wear again after half a year of use each time. After the repair using carbon nanopolymer this time, The technicians at the factory said that "it can last for at least two years."

Is the repair process fast?

Compared to expectations, the entire repair time was much shorter. After the engineer arrives at the site, he first measures the size of the worn area, and then directly applies the material to the worn surface with the help of special tooling. The material cures in just two to three hours. No need to wait, install the bearing directly after curing is complete. The workers did not completely dismantle the entire crusher, but only removed the relevant parts on the transmission side. From construction to start-up, the total time spent was less than eight hours. The production manager of the factory said that if we used the previous method of welding repair, we would have to stop work for at least three days.

Is there any damage to the equipment itself?

This is an issue of great concern to the company. Riveting and welding repairs require high-temperature heating, which can easily cause the shaft to deform and leave areas of stress concentration at the welding points. Sole's online repair does not require heating at all, nor does it require secondary processing of the shaft. The material is directly applied to the worn area and forms a strong bond with the shaft surface. There is no change in the structure and material of the shaft after repair. The Henan company previously caused a slight bend in the shaft head due to welding repairs. This time, the online process not only repaired the wear, The curvature was also corrected incidentally.

Is it difficult for workers to operate?

The repair operation is not complicated. Senior technicians are not required on site. Ordinary maintenance workers can master it after learning from an engineer for a while. The key is to clean the worn surface cleanly without oil or rust. Then use special tooling to evenly apply the material to ensure that the thickness remains consistent. Finally, wait for the material to solidify before assembly. When the Henan crusher was being repaired, two mechanics from the factory watched the whole process. Later, I tried to apply a small section by hand, and checked after curing. The thickness and surface smoothness all met the requirements.

Can it be used for a long time after repair?

Life span is a key hard indicator that cannot be ignored. Carbon nanopolymer materials have unique properties. When the eccentric shaft bearing position of a jaw crusher is worn and repaired by riveting and welding , metal fatigue wear will not occur. As long as the equipment is properly maintained during daily periods, the service life of the repaired parts will be longer than that of new parts. This company in Henan has repaired the wear and tear of the eccentric shaft bearing of the jaw crusher by riveting and welding. In the past, riveting and welding were used for repairs. Each time, it could only last for half a year at most. It repaired the wear of the transmission side bearing of the crusher three times. Don’t you understand how to repair the wear of the bearing on the transmission side of the crusher? , a lot of money was spent on this. After the repair was completed using this method, it has been three quarters so far, and the corresponding bearing position of the equipment has not shown any signs of looseness. Relevant personnel from the equipment department of the factory made careful economic calculations. After a comprehensive calculation, they concluded that taking into account the loss of the internal machine and the cost of repairs, the actual cost of this online repair was much less than the total cost of five riveting and welding repairs in the past. At present, their company also plans to use the same method to repair two other crusher equipment.
