390000 series of spherical bearings through the eccentric sleeve bearing inner ring and shaft fixed, eccentric set of hexagonal screws from the tightening effect. In maintenance, many hands will not disassemble this bearing, it is necessary to introduce disassembly 390000 series of spherical bearings of the technical points and precautions:
Removal
1. Loosen the locking screw on the eccentric sleeve of the bearing with an Allen wrench, then insert the counterbored hole in the cap eccentric sleeve with a small iron bar and loosen the eccentric sleeve against the rotation direction of the shaft.
2. Loosen the bolts securing the bearing housing. Remove the bearing from the shaft with the bearing housing. Note that before removing the bearing at one end of the shaft. Should be the other end of the shaft bearing bolts loose, so as not to end each other bearings do not damage.
installation
1. Before installing the bearings on the shaft, you must unplug the bearing pins from the bearing housing and smooth and clean the surface of the journal. Grease and lubricate the journal (allow the bearing to rotate slightly on the shaft).
2. In the housing and bearing with lubricant topcoat, the bearing into the bearing housing. The assembled bearing is then mounted on the shaft together with the bearing housing. Push to the desired location for installation.
3. Fixed bearing bolts do not tighten, let the bearing housing can rotate in the bearing housing. Also installed the other end of the bearing and the seat with a shaft, the shaft is rotated a few times, so that the bearing itself automatically after the alignment position. And then bolted the bearing bolt.
4. Eccentric sleeve. First condom eccentric eccentric steps in the bearing sleeve, and hand along the direction of the rotating shaft and tighten. And then insert or withstand a small iron bar eccentric sleeve Shen hole. Hand hammer along the axis of the rotation direction of the small iron bar. So that eccentric sleeve installed firmly, and finally locking the eccentric sleeve of the hexagonal screws.
