Каковы меры предосторожности при установке прецизионных подшипников?

Here are the revised points for installing precision bearings:

Ensure the shaft and housing hole concentricity and shoulder perpendicularity meet the specified accuracy for the bearing type.

Measure and control the interference fit of the rotating race accurately, and ensure the fixed race has an appropriate fit. Minimize interference in the rotating race to prevent thermal deformation and centrifugal force effects during operation, ensuring snug fit without risk of surface distortion.

For high-speed operation and elevated temperatures, ensure the rotating race fit is secure to prevent axial vibration, and maintain a gap-free fit for the fixed race to prevent deformation and vibration under load.

Use a small clearance fit for the fixed race only if the matching surfaces are highly precise with low roughness. Otherwise, assembly and disassembly may be difficult, and consider implications for spindle thermal expansion.

Spindles with double-row angular contact ball bearings typically experience lighter loads; avoid excessive interference fits to minimize internal structure radial moment and associated drawbacks.
