Bearing type is selected, it is essential to fully grasp the conditions of use of the bearing. Tianjin Han Huang-Seiko say something to you to choose the six-point considerations bearing:
1, direction and nature of the load bearing load bearing load capacity with a basic load ratings, the value contained in the the bearing size sheet bearing load varied, such as the size of the load, whether only radial load, axial load is a unidirectional or bidirectional, vibration, or the degree of impact etc.. After considering these factors, again select the most suitable type of bearing.
In general, the same as the inner diameter of the bearing radial load capacity according to the following order: deep groove ball bearings <angular contact ball bearings <cylindrical roller bearings <tapered roller bearings <Spherical roller bearings
2 of the inner ring and the outer ring relative tilt analysis relative inclined so that the bearing inner ring and the outer ring of factors (such as the load caused by shaft deflection, the accuracy of the shaft and housing, bad or mounting error), and choose to adapt this Using the condition of the bearing type. If the relative inclination of the inner ring and the outer ring is too large, the bearing will generate internal load damage. Should choose the type of bearing can withstand this tilt.
In general, allows the tilt angle (or aligning angle) is incremented in the following order:
Cylindrical roller bearings, tapered roller bearings, deep groove ball bearings (angular contact ball bearings), Spherical roller bearings (ball) 3) just the performance required to meet the mechanical shafting the rigid bearing type bearings to withstand load, scroll element and raceway contact portion is elastically deformed. "High rigidity" refers to the amount of deformation of this elastic deformation is smaller] in the machine tool spindle and the final-stage reduction gear device of the automobile and other parts, to improve the rigidity of the shaft at the same time, must also improve the rigidity of the bearing.
Roller bearings under load deformation of the students is smaller than the ball bearings. Preload (negative clearance) can increase the rigidity of the bearing. The method is suitable for the angular contact ball bearings and tapered roller bearings.
3 of the installation space of the bearing can be accommodated in the rigidity and strength of the bearing installation space within the bearing type because the axis-oriented design shafting, it is generally first determine the shaft, i.e., the bearing inner diameter. But there are a variety of rolling bearings of dimension series and type, should choose the most suitable type of bearing.
Generally use the following bearings:
Deep groove ball bearings, contact ball bearings, cylindrical roller bearings
4 rotating precision bearing dimensions and running accuracy by GB standardized bearing type? Machine tool spindle, gas turbine and control machine requires high rotational accuracy, high-speed and low-friction bearing type with the desired rotational accuracy In this case you should use more than five precision bearings.
5. Regularly check the installation and removal of the assembly and disassembly and installation method dismantle frequently use separable inner and outer rings of cylindrical roller bearings, needle roller bearings and tapered roller bearings is more convenient.
Speed can adapt the mechanical speed of the bearing type bearing speed limit value basis, with a limit speed, said the value contained in the bearing dimensions table bearing speed limit not only take on the bearing type is also limited to bearing size, cage type, accuracy class load conditions and lubrication methods, therefore, the choice must take into account these factors.
