Shaft and bearing fit tolerance: brake is shaking, bearing is broken

For later production cause safe hidden trouble, if the table measurement point is inside of the coupling, the ss of reading in the subsequent judgment to adjust fulcrum the number of calculation to be opposite. Wash the groove in the coarse, should avoid to turn the bearing, etc. With the brush after roughly clear the dirt on the adhesion in the bearing surface, in on the fine cleaning tank, in fine cleaning tank, bearing rotation to gently to clean. Bad bearing lubrication bearing the lack of oil pollution will cause bearing or bearing overheating, then need to change bearing oiling, cleaning, oil and sealing, check the oil and grease, in addition, there may be a bearing wear or bearing quality problems. In this case, should choose a more solid lubricating grease type, based on this, sauvy industrial recommend kinds of bearing wear technology at the site, the hope can give you help. Bearings are in a state of constant velocity, the device has high bearing capacity, long-term stress effect, lead to bearing relative to other parts, and prone to failure, in all kinds of mechanical failure type, bearing fault occupy larger proportion. If using swimming shall fraction of bearing support, just ring inside the bidirectional axial fastening on the shaft, the outer ring relative to the swimming hole axial freedom; When using internal and external ring can be divided into swimming the centripetal bearing support, the internal and external ring must be two-way axial fastening on the shaft and hole, inner and outer ring of bearing relative axial winding. Improper lubrication bearing fever bearing lubrication part design congenital deficiencies ZB excess number of kiln kiln head fan in years ( The early production) After the burning accident happened repeatedly bearing, the field screening, found problems and the oil standard of the bearing design. By heating box to remove the outer diameter, believe that through the right bearing removal method, you can effectively bearing for maintenance and change, improve equipment efficiency. Read on: kang-quan guo: enjoy the special allowance, won honorary titles such as department of agriculture has outstanding contribution to the young, in the first level and shaanxi province pacesetter engineering project in the first level five talents. Therefore, reducing not only improve the speed performance, the ball size and will not reduce the stiffness performance, it also from theory of divination and clear path of ball is the development trend of the main shaft bearing. This case if the poor lubrication of bearing, the parts surface roughness will continue to increase, which will lead to increase, gradually wear on the surface of the roller unit pressure is increasing, at the same time bearing in the process of operation, operation rolling element and raceway, rolling element and cage, cage and have the sliding friction between inside and outside the circle, and the sliding friction can increase with the increase of load, the existence of the sliding friction can cause relatively crawling occurs between bearing parts, in order to reduce the bearing parts relative to climb to the result of wear and tear, you must keep good lubrication between the bearing parts, lubricating film can be a good isolation between the various components of contact area, to avoid the direct contact friction between metal and metal. Crack when bearing parts by stress exceeds the ultimate strength of the material, the surface or the inner fracture or local fracture phenomenon occurs, its macroscopic defects is referred to as the crack.
