What are the installation methods of paired angular contact ball bearings? We introduce this article to you: 1. Usually, the feeler gauge is used for testing. For angular contact ball bearings with very large diameters, the clearance is very large, and a narrow feeler gauge should be used to measure immediately. For angular contact ball bearings with small apertures, the clearance will be very small, so there is no need to use a feeler gauge for measurement. 2. Another way is to measure the lead by pressing the lead to measure the clearance of the angular contact ball bearing. If the feeler gauge is used, it will be very laborious. Then, we usually use soft lead wire for measurement in specific work. For lead wire measurement, the soft lead wire used should be very soft, and the aperture should not be too long or too small. The most satisfying immediately is 1.5-2 times the gap. During the inspection, first open the outer cover of the angular contact ball bearing, use a reasonable soft lead wire, cut it into small pieces and place them on the bearing journal and the left and right bearing parts, then cover the bearing cover and tighten the screw bolts. Then loosen the anchor bolts, remove the bearing cover, and measure the thickness of the flattened lead wire with a vernier caliper to obtain the average value of the top clearance of the angular contact ball bearing. If the gap is too small, the upper and lower tiles can be fused with the surface pad; if it is too large, the pad should be reduced or the tiles should be poured again. After assembly and inspection, if there is no abnormal angular contact ball bearing, it can operate normally. The torque is accurate, in order to turn stable!
