Bearing axial clearance radial clearance of choice
Most favorable price : sales@hellerbearings.com
Clearance when operating ( called clearance work ) the size of the rolling bearing fatigue life , temperature , noise, vibration , etc. affect performance .
When measuring the bearing clearance , the so-called bearing clearance , meaning that the bearing is not installed on the shaft or bearing housing , the inner or outer side of its fixed , then the party do not fixed radial or axial when the movement amount . According to the direction of movement can be divided into radial clearance and axial clearance .
Clearance when operating ( called clearance work ) the size of the rolling bearing fatigue life , temperature , noise, vibration , etc. affect performance .
When measuring the bearing clearance, in order to obtain a stable measurement value, usually the bearing load is applied to a predetermined measurement .
Therefore, the measurement values ??obtained than the real clearance ( referred to as theoretical clearance ) is large, i.e., increasing the amount of elastic deformation produced by the load measurement .
But for the roller bearing , since the elastic deformation amount is small , negligible .
Internal clearance before installing the bearing clearance is generally represented by the theory .
Choose clearance
Minus the amount of expansion clearance of the bearing rings mounted in the shaft or housing complexes arising due to interference or shrink after called " installation clearance " from the theoretical clearance.
On the installation clearance subtraction amount due to changes in the internal bearing clearance dimensions after the temperature difference called "effective clearance ."
Bearing clearance is installed to withstand a certain load when placed on the machinery, namely the effective clearance plus load bearing elastic deformation produced after so called " clearance work ."
When working clearance for the micro- negative, the fatigue life of the longest but with negative bearing clearance with increasing fatigue life decreased significantly . Therefore , the choice of the bearing clearance, clearance work generally make zero or slightly positive appropriate.
In addition, the need to improve the rigidity of the bearing or the need to reduce the noise when working clearance should further be negative , and in bearing temperature violent , further work will have to take positive clearance and so on, but also a detailed analysis must be done in accordance with conditions of use .
