Bearing seat wear repair technology, what should I do if the bearing position is small?
What should I do if the bearing position is too small? In fact, bearing wear is a common and frequent equipment problem. Affected by the production environment and process, the proportion of different industries is different. The cause of bearing wear is mainly caused by the characteristics of the metal used to manufacture the shaft. Although the metal has good hardness, it has poor impact resistance, cannot be restore after deformation, and has poor fatigue resistance.
With the continuous improvement of the degree of automation and continuity of equipment in enterprises, how to quickly and effectively solve the problem of bearing wear and reduce maintenance costs, and ensure the safe and continuous production of enterprises is an important manifestation of the management ability of equipment managers in the new era.
The bearing position is small, the steps of Soleil carbon nanopolymer material to repair the bearing position wear online
-
Surface roasting oil: use acetylene oxygen for roasting oil;
- Surface grinding: use a grinder to grind the surface rough and clean to improve the adhesion of Soleil carbon nanopolymer material SD7101H;
- Clean the shaft surface with absolute ethanol, and brush the mold release agent SD7000 on the inner surface of the tooling;
- Calculate the amount of SD7101H, and reconcile SD7101H in proportion according to the calculation result;
- Apply the blended SD7101H evenly to the surface of the bearing position, install the tooling, and then heat it with an iodine-tungsten lamp for two hours to accelerate curing and improve material properties;
- After curing, disassemble the tooling, assemble the bearing, and start the operation.
The bearing position is 160mm, the width of the repair surface is 80mm, and the speed is 980r/min. The maintenance plan is immediately formulate, and engineers are dispatch to the scene with Soleil carbon nanopolymer materials SD7101H and SD7000.
Do you know modern bearing housing wear repair technology?
The bearing seat generally refers to the space where the bearing is install, and the machining accuracy is generally high. The outer ring of the bearing is fix, only the inner ring is rotate, and the outer ring remains stationary, which is always consistent with the direction of the transmission (such as the direction of the motor), and maintains balance.
Wear is the most common problem of bearing housings. The wear of bearing housings is mainly cause by the characteristics of the metal used to manufacture the shaft. Although the metal has good hardness, it has poor impact resistance, cannot be restore after deformation, and has poor fatigue resistance, so it is easy to cause equipment damage. Fatigue wear such as bearing seat wear, shaft head wear, journal wear, bushing wear, etc., most of the shaft wear is not easy to be found, when people find it, it has often cause the beating range of the machine to increase or noise. Increase, and cause machine downtime in severe cases.
In view of the problem of bearing seat wear and repair, most of the enterprises have always adopted traditional repairing processes such as welding, brush plating and spraying. These traditional processes have indeed help equipment managers to solve many equipment problems for a period of time, but with the improvement of modern production and operation and maintenance requirements, these traditional bearing seat wear repair processes are also affected by complex construction conditions and site environment. Restricted, especially in the face of some sudden emergencies, huge equipment, complex disassembly and other equipment problems, these technologies are obviously beyond their capacity.
Dan Shechtman, the Nobel Laureate in Chemistry once said frankly: The biggest limitation of today’s technology is the lack of material technology!
As a high-tech functional material, it can not only change the maintenance method of users in the future, but also make maintenance simpler, faster, more effective, more economical, more environmentally friendly, and longer equipment cycle life. For example, for the downtime caused by the wear and tear of transmission parts, it can basically achieve rapid on-site repairs and resume production within 3 to 6 hours.
