Zhejiang 6208 / HR11QN comb bearing manufacturing knowledge source: bearing | last updated: - 2020 06 - 11 6208 / zhejiang HR11QN bearing manufacturing knowledge comb bearing removing check, according to the damage of bearing bearing failure and damage reasons. 1. Metal flake bearing raceway surface rolling body and the inner and outer ring raceway surface under the role of the periodic pulse load, resulting in a periodic change of contact stress. When stress cycles after reaching a certain value, the rolling element bearings, their work within or surface produce fatigue spalling. If the bearing load is too big, can make the fatigue. In addition, the bearing installation is not straight, shaft bending, also can produce roll flaking off. Bearing raceway fatigue spalling can reduce the running accuracy of shaft vibration and noise in the organization. 2. Bearing burn burn bearing the heat tint of raceway and rolling body. Burns is usually the cause of insufficient lubrication, lubricating oil quality does not conform to the requirements or metamorphism, and bearing assembly too tight. 3. Plastic deformation of bearing raceway and roller contact surface appear uneven pits, bearing produce plastic deformation. The reason is bearing under static load or shock loading, local stress exceeds the yield limit of material on the surface of the work, this kind of situation usually happened in the low-speed rotation of the bearing. 4. Bearing race crack cause crack of the bearing race may be bearing fit tight, loose foreign or bearing inner ring, bearing deformation, inclusive of installation of bearing surface processing etc. 5. Cage fracture reason is the insufficient lubrication, rolling body breakage and seat skew, etc. 6. Retainers metal adhesion on the rolling body possible reason is that roller was stuck in a cage or insufficient lubrication. 7. Seat ring raceway serious wear and tear may be fall into the object in seat, lack of lubricating oil or lubricant brand is not appropriate. Bearing is widely used in the construction type of bearing is widely used in the construction, so what is the main layout characteristics of the bearing? What is the effect of the layout of the good or bad? Let the author to explain for everybody bearing main layout characteristics. Bearing is a kind of indispensable modern machinery and equipment parts. Its function is to support the mechanical body of revolution, which is used to reduce the equipment in the mechanical load friction in the process of transmission. High speed deep groove ball is a kind of guided by guard on inner and outer parts, due to its special features, high speed rotation bearing generally presents the arc shape deep groove, is mainly used to prevent the occurrence of radial load, and the components are basically by steel plate stamping cage for synthesis. This is the layout of the main bearing characteristics. If in doubt, you can call the query.
