Bearings are quite common in our lives. Bearings are an important part of mechanical equipment, but various problems are inevitable during use. In mechanical equipment, the engine state has a direct impact on the service life and work efficiency of mechanical equipment.

When using mechanical equipment, various factors will affect the working state of the engine. In particular, whether the engine is started correctly is directly related to the service life of the engine. Every time the engine is started, the wear of the cylinder wall and the piston ring is equivalent to the wear of 1.5 hours of normal operation. The problem of equipment wear caused by starting the engine cannot be ignored.

When designing and manufacturing mechanical equipment, the normal working load range will be set. When running at medium load, the wear of the parts can be greatly reduced to ensure that the mechanical equipment can reach the best working state for a long time. If the mechanical equipment is in an overload or high-load operation state for a long time, the wear resistance and strength of the internal parts cannot meet the requirements of overload operation, which will aggravate the vibration and wear of the equipment. If the engine cannot be cooled in time, the aging and wear of the equipment will be further accelerated, the frequency of equipment maintenance will increase, and the service life of the mechanical equipment will be greatly shortened. If some minor problems in mechanical equipment are not taken seriously by maintenance personnel, it will cause major obstacles to the equipment and affect normal production.

Mechanical maintenance methods, to ensure that mechanical equipment can work normally, it is necessary to carry out necessary repairs and maintenance on its worn parts. Maintenance is an effective way to restore the normal operation of machinery, eliminate hidden dangers of mechanical failures, and extend its life. Structural patch repair technology, for the damage problem of thin-walled structural parts in mechanical equipment, the structural patch repair technology is used to effectively repair damage such as cracks and holes in the structural parts. We generally use a new type of structural adhesive that cures at room temperature to directly patch the damaged holes. This patch has a short curing time and high strength. It is an effective in-situ repair technology, which plays a huge role in improving maintenance efficiency and ensuring the smooth operation of production.

Nano brush plating technology, in the process of repairing mechanical bearings and machine tool guides, we used nano brush plating technology to effectively repair the wear of machine tool guides and improve the motion accuracy of machine tools. Using this technology, machine tools can be transformed, CNC machine tool transformation can be deepened, and nano brush plating technology can be used in the maintenance of mechanical bearings, rods, and bearing parts. It is very suitable for the maintenance of gears, parts holes, slots, shells, and box parts.

For the maintenance of mechanical bearings, the damage rate of bearings is relatively high in mechanical equipment. We first analyzed and studied the failure mechanism of bearings. When the bearing is in a constant speed state, the bearing capacity is very large. During the operation of the machine, the looseness of the sealing sleeve or screws will cause the rolling body to wear. Sometimes, cracks will appear in the gland or sleeve of the bearing, and some dust or debris, water, etc. will enter the bearing box through these gaps. The function of the lubricating oil cannot be fully exerted so that the bearing will be blocked.

High-speed arc spraying technology uses arc asa heat source to produce wear-resistant coating and anti-corrosion coating. When repairing and processing large parts of mechanical equipment, this technology is used to effectively enhance the anti-corrosion and wear-resistant performance of the equipment, and the corrosion problems of some steel structures in the equipment have been effectively improved.

Use electronic technology to quickly clean equipment. Since mechanical equipment is often affected by the environment during production and operation, there will be some dust, dirt, and some acid, alkali, and salt components in the atmosphere deposited on the surface of the mechanical equipment. These pollutants will seriously affect the normal performance of the mechanical equipment and require us to clean them frequently. The disassembly and wiping methods are used. In this case, it is more troublesome and not conducive to cleaning. It will leave some hidden dangers. Sometimes during the disassembly process, it will cause a certain degree of damage to the components. Using electronic equipment to quickly clean the machinery effectively improves these phenomena. It not only maintains the equipment well but also saves time and plays a great role in ensuring the integ
