Bearing clearance means bearing relative displacement, both inside and outside the circle of the radial displacement called radial clearance and axial displacement called axial clearance. General spherical roller bearing a radial clearance.
The bearing clearance impact on the three aspects
Inside and outside interference caused by installation, circle circle up inside and outside shrinks, cause clearance changes.
Operation of a saturated temperature reached, but the internal and external circle, lead to different heat inside and outside temperature from different circles, temperature difference in temperature and clearance changes.
Because of the load caused by internal and external circle around and rolling bearing the elasticity of the body changes that lead to clearance changed.
Bearing clearance changes are very complex, we should first of all kinds of clearance definition the understanding. Specific see figure 1
