Insert the installation of the spherical bearing the technical key points and matters needing attention

Set-contained spherical bearing of rolling mill and its control method for roll is cylindrical roller bearing in the harsh metal can occur in all occasions, mostly happens in large type bearing grease lubrication, and in the performance degradation occurred more often in grease base oil, almost does not occur when oil lubrication. In addition, more easily occur during the winter, when under pure radial load, the radial clearance prone to big occasions, and takes different outer spherical bearing type size, easy to happen in a certain speed range, both continuous and intermittent. External ring raceway take special processing method can prevent the occurrence of roll ring, can choose this kind of bearing, if necessary or appropriate to reduce bearing radial clearance, the use of high performance grease and improve to suit the bearing parts of rigidity. ( 1) The correct installation, for the use of insert ball bearing unit is very important. I hope you can in the later use with correct installation method. ( 2) When installation, can according to its type and size, select machinery, such as heating or hydraulic method. When installation force to insert ball bearing, never can be passed on from a roller bearing ring to another bearing ring, otherwise it may cause damage to the race. But in any case, all can't knock directly bearing ring, cage, rolling body or seals. ( 3) Eccentric sleeve. The eccentric sleeve installation is firm, finally lock eccentric sleeve on the socket head cap screw. ( 4) Fixed bearing bolts do not tighten, let rotation reaction in the bearing seat insert spherical bearing coat. Then good bearing bolts. Also installed on the same shaft, on the other side of the bearing and shaft turning laps, make automatic alignment position bearing itself. ( 5) Coating on surface of the bearing and the bearing lubricating oil, put the bearing into the bearing seat. Pushed to the required location for installation. Insert ball bearing dismantling skills maintenance method and the main technical points of the bearing installation bearing ( 6) To the shaft is installed on insert ball bearing unit before, must first remove the bearing a coat of fixed pin, the shaft neck at the same time clean exterior burnish is smooth, and shaft neck with anti-rust and lubrication oil ( Allows for a slightly bearings on the shaft rotation) 。
