Precautions precision bearing configurations

1. This type of spindle is usually passed through a pulley or gear drive torque. This means that the load on the drive end of the spindle is also quite large. Such applications for speed is not too high, more important parameter is the stiffness and load carrying capacity.
2. In order to improve the accuracy of the actual mating bearing installation, you must not make use of measurement methods and tools bearing deformation of the precision spindle bearings bore and outer dimensions of the actual mating surface precision measurements can be related to inner and outer diameters All measurement items to be measured, and the measured data to make a comprehensive analysis on this data, the precision worthy of the shaft and housing bore bearing mounting portion sizes.
3. take a small circle on the fixed interference fit condition to match the shape of the surface of both sides have high accuracy and less roughness, or cause installation problems and disassembling harder, also need to consider the thermal elongation of the spindle.
4. Note to match the mechanical fine Italian secret if it is not bearing the above requirements, often makes precision bearings occur several times larger than the original bearing error after installation, or even 10 times more errors completely ceases precision bearings, because to match the mechanical error is often not simply superimposed on the bearing error, but in an enlarged after different multiple additions.
5. Turn the accuracy requirements are not the same value, the product of its high level of accuracy precision rotation (inner diameter of the beating, the outer diameter of the beating, the side facing the raceway runout, etc.) value lower than the accuracy level of product requirements to be strict.
6. iso precision bearings in accordance with the classification criteria are divided into:. P0, p6, p5, p4, p2 successively higher grades, where p0 is the general accuracy of the other grades are precision level. Of course, different classification criteria, different types of bearings, their method for classifying different, but the meaning is same.
