Disassembling outer spherical bearing knowledge of skills - bearing

Outside the spherical bearing is a bearing outer ring looks like a sphere, bearing sealing cover automatically self-aligning bearing on both sides of the belt. Series 390000, outer spherical bearing is a common agricultural machinery, a 2, Mr Fukuda, the central plains in xinjiang on the combine harvester, are widely adopted the bearing, a locomotive used on up to more than 30. Series 390000, outer spherical bearing is through the eccentric sleeve bearing inner ring with fixed axis, eccentric sleeve on the socket head cap screw fastening effect. With Allen wrench to loosen the lock screw on the eccentric bearing sets, and then with a small iron rod inserted into the roof sink hole on the eccentric sleeve, against the direction of the axis of rotation to play loose eccentric sleeve. Unscrew the fixed bolt of the bearing. From the bearing, together with the bearing on the shaft will be unloaded. Should be on the other end of the shaft bearing bolt loosening, lest bearings on both ends don't strength and damage to each other. To shaft bearing before installation, must first remove the bearing a coat of fixed pin, the shaft neck at the same time clean exterior burnish is smooth, and the journal oil anti-rust and lubrication ( Allows for a slightly bearings on the shaft rotation) 。 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. Fixed bearing bolts do not tighten, let bearing coat in bearing internal energy. Also installed on the same shaft, on the other side of the bearing and shaft turning laps, make automatic alignment position bearing itself. Then good bearing bolts. Eccentric sleeve. The eccentric sleeve installation is firm, finally lock eccentric sleeve on the socket head cap screw.
