1 This type of spindle is usually transmitted through a pulley or gear drive torque. This means that the load of the drive end of the spindle is quite large. Such applications of the speed is not too high, and more important parameter is the stiffness and load bearing capacity.
2 In order to improve the accuracy of the bearing with the actual installation, you must not make use of measurement methods and instruments bearing deformation of the bearing bore and the outer dimensions of the actual mating surface precision measurement can be related to inner and outer diameters All measurement items to be measured, and the measured data to make a comprehensive analysis of this as far as precision worthy of the shaft and the plastic bearing seat hole Wind turbine bearing the size of the installation site.
3 laps to take a small fixed interference fit condition is to match the shape of the surface of both sides have high accuracy and less roughness, or cause installation difficulties disassembly harder, in addition, also need to consider the impact of the spindle thermal elongation.
4 Note fine Italian secret bearing parts if it is not matched plastic bearing these requirements, often makes precision bearings error occurs several times larger than the original bearings after installation, or even 10 times more errors, precision bearings completely not become Rolling mill bearing due often not match the mechanical error is superimposed on the bearing simply error, but in the type of amplification with multiple go.
5 rotating accuracy requirement values are not the same, high level of accuracy of the product rotational accuracy (internal diameter runout, diameter to beat, beating raceway end face, etc.) value lower than the accuracy level of product requirements to be strict.
6 precision bearings in accordance with the grading standards iso divided into:. successively higher level, where p0 ordinary precision, all other levels of precision levels. Of course, different classification criteria, different types of bearings, their classification methods vary, but the meaning is the one to
