General bearing pressure in the 0.02 to 0.04 mm. If the clamping force does not meet the standards, you can increase or decrease the bearing and the bearing seat surface of the gasket thickness method to adjust, tile back not allowed to pad.
When the sliding bearing clearance does not meet the requirements, should be adjusted. Radial bearings are often used to adjust the radial gap (top clearance).
In addition to radial clearance to ensure that the sliding bearing, but also to ensure that the axial clearance. When checking the axial clearance, move the shaft to an extreme position, and then use a feeler or dial indicator to measure the amount of axial movement of the shaft from one extreme position to the other.
Test, first bearing cover to open, the appropriate diameter of lead wire, cut into 15 ~ 40 mm long segment, on the journal and upper and lower bearing interface, cover the bearing cover, according to the provisions of the torque tightening bolts , And then loosen the bolts, remove the bearing cover, with a micrometer to detect flattened lead wire thickness, the average bearing clearance obtained.
If the top gap is too small, can be in the upper and lower tile surface with pad. If it is too large, reduce pad, scraping or re-watered tile.
Bushing tightening force adjustment: In order to prevent the bearing in the course of work may occur in the rotation and axial movement, in addition to the interference and stop with the parts, the bearing must also be used to bear the bearing cover, measuring methods and measuring the same gap method , Measured the thickness of the soft lead wire, can be used to calculate the bearing tighter force (with the bearing deformation of the elastic deformation to represent)
The clearance between the bearing and the shaft must be suitable. The following methods can be used to detect the radial clearance.
2, pressure lead detection method
1, ruler detection method
For bearings with larger diameters, the clearance is larger to allow direct inspection with a narrower feeler. For smaller diameter bearings, the gap is small, not easy to measure with a feeler, but the bearing backlash, the thickness must be measured with the appropriate feeler.
It is more accurate to measure the bearing clearance with the pressure lead method than with the feeler gauge. Detection of aluminum wire used should be soft, not too large or too small diameter, the ideal diameter of 1.5 to 2 times the gap, the actual work is usually detected with a soft lead wire.
