The analysis of the factors affecting the service life of deep groove ball bearings, bearing

Deep groove ball bearing material to a great extent, determines the service life of bearing, ever bearing steel GCr15 metallurgical quality is the main cause of premature failure of the rolling bearing. In metallurgical technology improved, bearing steel, there appeared after the material such as, are improved greatly. In bearing failure analysis, the proportion of bearing failure caused by the raw materials have been improved a lot, but still made of bearing failure is the main reason, more and the service life of deep groove ball bearings have a considerable relationship. Bearing manufacturing complex, can get the finished product after a multi-channel processes, including forging, heat treatment, turning and grinding process of technology capability and complete quality, will affect the service life of the bearing and its application effect, especially in heat treatment and grinding process, but also a lot of bearing the proximate cause of the failure to get production enterprise attaches great importance to. Deep groove ball bearings after installation, in order to check if installed correctly, check for running. Small mechanical can rotate with the hand, to determine whether rotate smoothly. Check project are mainly caused by foreign material, indentation seized up, due to bad installation, installation of the processing and the torque is not stable, because of the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation. In the shaft and bearing seat, bearing requirements in the radial, axial and tangential direction to three directions such as fixed position. Through the positioning of the radial and tangential the tight fit of bearing ring, the axial positioning only in a few cases with tight fit; Generally USES the axial spacing parts, such as end cover and retainer could happen on the axial location clearance range. Choosing cooperation should focus on the following four: ( 1) Bearing ring circumferential surface should have good bearing and force uniform, in order to reduce the deformation, and can give full play to the bearing capacity of the bearing. ( 2) Ring in its surface can't slide along the tangent direction, otherwise it will damage the mating surface. ( 3) Freedom end bearing must be able to adapt to changing with the length of the shaft and bearing seat holes, which must have to adapt to the axial location within a certain range of swimming ability. ( 4) Must pay attention to the erection and dismantling of deep groove ball bearing is simple, saving time and costs for the province. Bearing on production of 2 mm diameter 30 ~ 40 mm 30 small small-sized bearing, has high precision, small vibration, low noise, high performance, high speed, long life and other excellent features. Widely used in household appliances, electric tools, small-sized electric machinery, fitness equipment, office automation equipment, medical equipment, instrumentation, internal combustion engines, construction machinery, railway vehicle, loading and unloading handling machinery, agricultural machinery, all kinds of industrial machinery, etc. Buy miniature bearings, motor bearings, deep groove ball bearing, please find bearing.
