Performance and bearing type of relationship

3. 5 stiffness performance and bearing type when applying load on rolling bearing, the relationship between some elastic deformation in the contact area between the rolling element and raceway. The bearing stiffness is decided by the proportion of bearing load of elastic deformation and rolling element on inner and outer. In order to machine tool spindle, it is necessary to high rigidity along with the rest of the spindle bearing. Therefore, because of the roller bearing is through the load deformation is small, they are often chosen than ball bearings. When a high stiffness, for a given bearing preloading, which means that they have a negative clearance. Angle of contract ball bearings and tapered roller bearings often pre-installed. 3. Six types of bearing noise and torque due to very high precision rolling bearing manufacturing, noise and torque are small. For deep groove ball bearings and cylindrical roller bearing, especially the noise levels are sometimes designated depends on their purpose. High precision miniature ball bearings, starting torque requirements. It is recommended to use low noise deep groove ball bearing and torque application needs, such as electrical and instrument. 3. 7 for running performance and precision bearing type of relationship of main spindle high running accuracy or speed applications such as supercharger, 5, 4 or higher precision bearings usually use running precision of the rolling bearing in various ways, and specify the accuracy grade of different depends on the type of bearing. The comparison of the inner ring radial runout highest run for each bearing type specified accuracy as shown in figure 3. 6. For the application of high precision operation, deep groove ball bearings, angular contact ball bearings, cylindrical roller bearing is most appropriate. 3. 8 types of installation performance and the relationship between bearing type bearing type of separable cylindrical roller bearing is bearing, needle roller bearings and tapered roller bearing disassembly convenient installation. For regular check, the erection and dismantling of bearing machine often these types of bearings is recommended. In addition, since the self-aligning ball bearing and spherical roller bearing, Small) With cone hole can use are relatively easy to install and remove.
