Bearing is quite common in our life, bearing is an important part of mechanical equipment, but in the process of use will inevitably appear a variety of problems, in mechanical equipment, engine state has a direct impact on the service life and work efficiency of mechanical equipment.

When mechanical equipment is used, various factors will affect the working state of the engine. In particular, whether to start the engine correctly is directly related to the service life of the engine. For each engine start, the cylinder wall and piston ring wear is equivalent to 1.5 hours of wear during normal operation. The problem of equipment wear caused by starting the engine is not negligible.

In the design and manufacture of mechanical equipment, the normal working load range will be set, medium load operation can largely reduce the wear of parts, to ensure that the mechanical equipment can reach ****** working state in a long time. Mechanical equipment in overload or high load operation state for a long time, the wear resistance and strength of the internal parts can not meet the requirements of overload operation, it will aggravate the vibration and wear of the equipment, if not timely heat dissipation of the engine, it will further accelerate the aging and wear of the equipment, increase the maintenance frequency of the equipment, the service life of the mechanical equipment will be greatly shortened. Some small problems in mechanical equipment, if maintenance personnel do not pay attention to, will cause big obstacles in equipment, affect the normal production.

Mechanical maintenance method, in order to ensure that the mechanical equipment can work normally, it is necessary to carry out the necessary repair and maintenance of the worn parts. Maintenance is an effective method to restore the normal work of machinery, eliminate hidden trouble and prolong its life. Structural patch repair technology. For the damage problem of thin-wall structural parts in mechanical equipment, the structural patch repair technology can effectively repair the damage of structural parts such as cracks and holes. We generally use the new structural adhesive curing at constant temperature and light to directly repair the damaged holes, which has short curing time and high strength. It plays a great role in improving maintenance efficiency and ensuring the smooth operation of production.

Nano brush plating technology, in the process of mechanical bearings and machine tool guide rail maintenance, we use the nano brush plating technology, effectively repair the wear of machine tool guide rail, improve the machine tool motion accuracy. Using this technology, the machine tool can be transformed, deepen the transformation of CNC machine tools, mechanical bearings, rods and bearing parts can be used in the maintenance of nano brush plating technology, for gear, parts hole and groove parts or shell, box parts maintenance, nano brush plating technology are very suitable.

For the maintenance of mechanical bearings, the damage rate of bearings is relatively high in mechanical equipment, so we first analyze and study the failure mechanism of bearings. Bearing in the state of constant speed, bearing capacity is large, in the process of mechanical operation, due to the loosening of the sealing sleeve or screws and other parts, will cause the wear of the rolling body, sometimes, bearing gland or sleeve will appear cracks, some dust or debris, water and so on will enter the bearing box through these gaps, the function of lubricating oil can not give full play to, so, There will be obstacles in the bearing. High speed arc spraying technology, high speed arc spraying technology to arc as a heat source, can produce wear-resistant coating and anti-corrosion coating, in the maintenance and treatment of large parts of mechanical equipment, the use of this technology, effectively enhance the anti-corrosion, wear resistance of the equipment, the corrosion of some steel structure in the equipment has been effectively improved. The use of electronic technology to quickly clean equipment, because mechanical equipment in the process of production and operation, often affected by the environment, on the surface of mechanical equipment there will be some dust, dirt and the deposition of some acid, alkali and salt components in the atmosphere, these pollutants will seriously affect the normal performance of mechanical equipment, we often need to clean up. All use disassembly and wiping method, in this case, more trouble, is not conducive to thorough cleaning, will leave some hidden dangers, sometimes in the process of disassembly, will cause a certain degree of damage to the components. The use of electronic equipment for rapid cleaning of machinery has effectively improved these phenomena, not only for good maintenance of equipment, but also to save time, and to ensure the integrity of the equipment has also played a great role.

In the process of bearing maintenance, first of all, we should understand the bearing model and code in detail, try to use the original model, some equipment connecting rod bearings often appear damaged, bearing outer ring on the connecting rod hole is difficult to take off, if the hacksaw saw, easy to slip, but also easy to damage the connecting rod, this time you can put the connecting rod on the pliers, With the sleeve head against the outer ring of the bearing, at the other end with a slightly larger sleeve head against the side, clamp the bench pliers, at this time, the bearing outer ring will be pressed out. It is worth noting that the inner and outer rings of the bearing must not be knocked directly. Timely inspection of bearings, if small problems are found, countermeasures should be taken as soon as possible.
