Crack damage of non-standard bearing countermeasures and solutions of the internal structure of the analysis of the principle

Crack damage of non-standard bearing countermeasures and solutions of the internal structure of the analysis of the principle of source: bearing | last updated: - 2020 09 - 08 crack damage of non-standard bearing countermeasures and solutions of non-standard bearing fracture characteristics and formation conditions: often occurred in parts and components, raw materials, carbon belt and segregation is serious or not included in the longitudinal extension, from surface to inner crack, crack depth, length of hardenability. Solutions and preventive measures: eliminate carbon belt and organization, not too much impurity of raw material segregation; The rational development of heat treatment parameters, as far as possible factors in the person's action. Characteristics and formation conditions of quenching crack, not often occur in the carburizing and quenching parts or components, and the thickness crack in part on the forefront of the gap. Solutions and preventive measures, the key is to formulate a reasonable heat treatment process parameters, in order to improve the operator's skills, try to eliminate the artificial operation factors; Design, the use of circular arc transition that avoid sharp corners. Characteristics and conditions of the formation of quenching cracks, on the surface is easy to produce such grinding crack. Parts of high hardness solutions and preventive measures: tempering heat treatment fully; When grinding feed smaller, reducing grinding heat. Bearing damage: a, if the correct use of non-standard bearings, can be used to achieve fatigue life. But there will be unexpected injury prematurely, not resistant to use. This early damage, and fatigue life, it is called the fault or the quality using the limit of the accident. Much due to the installation, use, do not pay attention on the lubrication, intrusion of foreign bodies from outside, to the shaft, shell heat affected study enough. Affect the internal structure of 0 kinds of non-standard bearing 0 kinds of non-standard bearing analysis principle of impact roller in use is the internal structure of roller performance reasons. Poor bearing alignment: roller bearing used in stamping, cooperate with drum skin is not processed, housings welded directly on the tube of the skin. two Sealing effect is bad, the waterproof effect is poorer, and the production status of the mine belt conveyor is large dust, water dust removal at the same time, so the seal used in roller must has good dustproof and waterproof effect. If water will corrosion in roller bearings, bearing damage, into the dust affects the service life of roller. 3. Supporting roll shaft alignment: because of the cold drawing axis production due to factors such as the wear and tear of milled dimension precision is not stable, often have a violation, and easy cause bending in the transport process, make the alignment of the roller is poor, installed on both ends of the supporting roller bearing clearance is not guaranteed, and roller rotation resistance increase, affect the service life of the roller conveyor belt
