Mechanical maintenance points bearing maintenance technology in the process of analysis

Mechanical maintenance bearing maintenance technology in the process of the 2020 - point analysis 11 - 06 abstract: with the development of the current mechanical equipment in our country, the application of popularization, the demand for machinery and equipment repair and maintenance are also increasing, thus to ensure the stable operation of the machinery and equipment, it must strengthen the maintenance of mechanical equipment. In the process of mechanical maintenance due to the particularity of bearing parts, bearing maintenance must be effective research and analysis on the main technical points. Bearing common fault and problems were introduced simply, and analyzes the bearing maintenance technology main points, hope to be helpful to the mechanical equipment maintenance in China. Bearing belongs to the core part of the whole machinery and equipment parts, can effectively guarantee the stable operation of cooperate with the other parts. If the bearing problems will directly affect the stability and precision of the equipment, even threaten the life of the equipment, so we must strengthen the bearing faults in the mechanical equipment maintenance. 1 common fault usually bearing, bearing parts of the common faults are: bearing discoloration, crack of bearing inner ring and outer ring, bearing corrosion, ball bearings, or roller broken, bearing raceway pit scar, the phenomenon such as bearing rotating laborious. Aiming at the problem of bearing discoloration caused mainly because of continued operation under the condition of high temperature, at the same time, the inside of the bearing lubrication condition is not up to standard, bearing different between hole and shaft neck, or pollutants into the bearing which can lead to failure; General crack phenomenon in view of the bearing inner and outer circle, most larger bearing by external shocks, or its internal various defects caused by, and may be because the bearing inner and outer ring with a hole with the bad problems such as; Bearing corrosion mainly because of the sealing system of bearing parts caused by corrosion; Ball or roller bearing fracture may be due to the ball or roller bearings to smaller installation space and external large punch, or mixed with other hard material cause its broken beads; And pit in raceway scar is due to bad lubrication with external strongly impact is likely to lead to the emergence of this phenomenon; Bearing rotational failure painfully, bearing not clean, bearing deformation force is too large, or is a major cause of the failure. 2 the main points 2 bearing maintenance technology. 1 to strengthen the bearing quality inspection in the repair of damaged serious bearing, the need to replace the original bearing, thus requirements bearing with the following criteria: first, to clear the bearing type, bearing the important parameters, such as make sure it is consistent with the original bearings, it is forbidden to use other same model of bearing for replacement. Also, check the quality of bearing, because at this stage of the bearing quality is uneven in the market, if you do not increase the quality inspection will affect the mechanical equipment operation, so in the bearing replacement should first choice brand bearing manufacturers. The last is the demands of the bearing installation instructions, choose the appropriate tools to install, avoid all kinds of violence to remove and later installation. 2. 2 seat remove in carries on the repair process, bearing bearing race sealed, good or bad will directly affect the quality of bearing. Because in the majority of bearing in the process of maintenance, tend to produce bearing outer ring set in connecting rod hole tightly, eventually led to the bearing, the phenomenon of the disassembly difficulty, maintenance personnel will often use a hacksaw in the processing of bearing outer ring, but because of the bearing outer ring material is relatively hard, hard to avoid can cause some damage to equipment. Can use connecting rod vice clamp and set of head to the side of the connecting rod hole, thus squeezing bearing outer ring out, also can effectively reduce the damage to equipment. 2. 3 to ensure correct bearing installed on the maintenance to ensure the bearing installation precision, it must be good control of bearing installation direction, and avoid the forward and reverse installation error and influence to the operation of the equipment, so will ask maintenance personnel work in strict accordance with the following contents: first asked related personnel to bearing installation requirements and the characteristics of structure analysis and contrast, for the master bearing installation process and specification, to ensure that its in the installation work can be in strict accordance with the relevant specification and installation parameters for homework. To install to ensure the bearing axis position does not happen again, general to make a correction to the center position, after the installation using lubricating oil to fill and lubrication, prevent bearings under high temperature and pressure and wear, and appear all sorts of failure problems. The last is to strengthen the bearing after the installation of training work, make sure its in the mechanical equipment can stable operation, if produce problem, a thorough check, should be timely stop to avoid the secondary damage to equipment, effective guarantee for the stable operation of the bearing. 3 conclusion in the process of mechanical equipment maintenance is of great significance to strengthen the maintenance of bearing, both to ensure that daily lubrication of bearings and debugging of parts firmness, the comprehensive inspection on the bearing and mechanical regularly. And continuous upgrading of the quality of maintenance personnel, through the operation of the maintenance staff to strengthen the standards bearing repair and maintenance, to ensure the stability of the mechanical equipment operation. （ Source: agricultural machinery use and maintenance)
