The radial clearance is viewed as follows: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
First, the feeling of the law 1, the hand to change the bearing; the bearing should be smooth and sensitive without card 涩 representation.
2. Shake the outer ring of the bearing by hand; even if the radial clearance is only 0. 01mm; the axial movement of the uppermost point of the bearing; there are also 0. 10~0. 15 mm. This method is dedicated to single row radial ball bearings.
Second, the measurement method 1, with the feeler gauge; recognize the maximum load of the rolling bearing; between the 180 ° rolling body and the outer (inner) ring into the feeler gauge; the elastic thickness of the feeler gauge is the bearing radial Clearance. This method is widely used in self-aligning bearings and cylindrical roller bearings.
2. Use a dial gauge to check; first zero the dial gauge; then push up the outer ring of the rolling bearing; the dial gauge reading is the radial clearance of the bearing.
The way to view the axial clearance is as follows:
1. Feel the finger to check the axial clearance of the rolling bearing; this method is applied to the occasion where the shaft end is exposed. When the shaft end is closed or cannot be viewed with fingers for other reasons, it can be seen whether the shaft can be changed sensitively.
2, the measurement method (1) with a feeler gauge; the operation method is the same as using the feeler gauge to view the radial clearance; but the axial clearance should be c = λ / (2sinβ)
Where c axial clearance; mm,
λ feeler thickness; mm,
轴承 bearing cone angle; (°).
(2) View with a dial gauge; use the crowbar to move the axis so that the axis is at the two pole orientations; the difference between the dial gauge readings is the axial clearance of the bearing. However, the force applied to the crowbar should not be too large. Otherwise, the shell will be elastically deformed; even if it is very deformed, it can be boiled.
