Repair methods for mechanical bearings

Bearings are quite common in our life, bearings are an important part of mechanical equipment, but inevitably there will be a variety of problems in the process of use, in mechanical equipment, the engine state has a direct impact on the life and efficiency of mechanical equipment.

When using machinery and equipment, various factors will have an impact on the working state of the engine. Especially whether the correct start engine, directly related to the engine life. Every time the engine is started, the cylinder wall and piston ring wear is equivalent to its normal operation of 1.5 hours of wear. Have to start the engine caused by equipment wear problems can not be ignored.

In the design and manufacture of machinery and equipment, will be set to its normal working load range, medium load operation can largely reduce the wear and tear of the machine parts, to ensure that in a longer period of time machinery and equipment can reach ****** working condition. Mechanical equipment for a long time in the overload or high load running state, the internal wear resistance and strength of the machine parts can not meet the requirements of overload operation, will intensify the equipment vibration and wear, if not timely heat dissipation of the engine, to further accelerate the speed of equipment aging and wear, so that equipment maintenance frequency increases, the service life of machinery and equipment will be greatly shortened. Some small problems in mechanical equipment, if the maintenance personnel do not pay attention to, will cause the equipment to appear large obstacles, affecting normal production.

Mechanical maintenance methods, in order to ensure that mechanical equipment can work properly, it is necessary to carry out the necessary repair and maintenance of its wear parts. Repair is an effective way to restore the normal work of machinery, to exclude the hidden danger of mechanical failure and to extend its life. Structure patch repair technology, for mechanical equipment in the thin-walled structural parts of the damage problem, the use of structural patch repair technology, effective repair of structural parts of the rupture and holes and other damage, we generally use room temperature light curing new structural adhesive, direct patching broken holes, this patch curing time is short, strong, is an effective in situ repair technology, to improve maintenance efficiency and ensure the smooth operation of production plays a huge role.

Nano brush plating technology, in the process of repairing mechanical bearings and machine tool guides, we use nano brush plating technology to effectively repair the wear and tear of machine tool guides and improve the accuracy of machine tool movement. The use of this technology, you can transform the machine tool, deepen the transformation of CNC machine tools, mechanical bearings, rods and shingles in the maintenance of parts can be used in nano-electric brushing technology, for gears, parts of the hole and slot parts or shell, box parts of the repair, nano-electric brushing technology are very suitable.

The repair of mechanical bearings, in mechanical equipment, the damage rate of bearings is relatively high, we first analyzed and studied the failure mechanism of bearings. Bearings in the state of equal speed, bearing capacity is very large, machinery in the process of operation, due to seal bushings or screws and other parts of the loosening, will cause the rolling body wear, sometimes, bearing gland or bushings will appear cracks, some dust or debris, water, etc. will enter the bearing box through these gaps, the function of lubricating oil can not give full play, so the bearing will appear obstacles.

High-speed arc spraying technology, high-speed arc spraying technology with electric arc as the heat source, can create a wear-resistant coating and anti-corrosion coating, in the maintenance and treatment of large parts of machinery and equipment, the use of this technology, effectively enhance the anti-corrosion and wear-resistant performance of the equipment, equipment in some steel parts structure corrosion problems have been effectively improved.

The use of electronic technology to quickly clean equipment, due to mechanical equipment in the production and operation of the process, often affected by the environment, in the surface of mechanical equipment will have some dust, dirt and some acid and alkali salt components of the atmosphere deposition, these pollutants will seriously affect the normal performance of mechanical equipment, we need to clean up frequently. All use the method of disassembly and wipe, in this case, more trouble, but also not conducive to cleaning, will leave some hidden problems, sometimes in the process of disassembly, the components will cause a certain degree of damage. The use of electronic equipment for rapid cleaning of machinery will effectively improve these phenomena, not only a good maintenance of equipment, and save time, to ensure the integrity of the equipment also played a big role.

In the process of repairing the bearings, first of all, we need to understand in detail the type and code of the bearings, try to use the original model, some equipment often damage the connecting rod bearings, bearing outer ring in the connecting rod hole is difficult to take down, if you use a hacksaw, easy to slip, but also easy to damage the connecting rod, this time you can put the connecting rod in a vise, with a socket head to hold the outer ring of the bearing, at the other end with a slightly larger The other end with a slightly larger sleeve head against the side, clamping vise, at this time, the outer ring of the bearing will be pressed out. It is worth noting that the inner and outer rings of the bearing must not be directly knocked. Timely inspection of the bearing, if you find a small problem, you should take countermeasures as soon as possible.
