1. Loosen the fixed bearing bolts. Bearing removed from the shaft together with the bearing seat. Note that before the the demolition shaft at one end of the bearing. The other end I should shaft bearing bolts loosen, to avoid both ends of the bearing damage each other do not Jin.
2. Use the hex wrench to loosen the bearing eccentric sleeve locking screw, then cover eccentric sleeve is inserted with a small iron bar sink hole, loosen the eccentric sleeve against the axis of rotation direction.
A lot of people use improper bearing installation installation method, resulting in damage to the bearing. So how do you correct installation bearing it? I hope everyone more comprehensive understanding of the installation and removal of the bearing:
For the clearance fit the bearing ring, it is recommended that in line with the topcoat of a thin layer of anti-creep etchant, to prevent the friction generated between the mating surfaces corrosion.
390 000 series spherical bearing eccentric sleeve the fixed bearing inner ring and the shaft from the eccentric sleeve socket head cap screws fastening. Maintenance machine hand will not dismantling such bearings, it is necessary to introduce disassembly of the technical points and Notes 390 000 series spherical bearings:
Proper installation, it is very important for the use of the bearing. I hope that we can use the correct installation method.
Installation, according to their type and size, select the machinery, such as heating or hydraulic method. Install, when the biasing force applied to the bearings, not by the rolling body is passed from one bearing ring to the other bearing ring, or may be interested in the raceway damage. But in any case, do not directly hit the bearing ring and the cage, the rolling body or the seal member.
3. Install the eccentric sleeve. First eccentric condom sleeve bearing eccentric steps, and smooth shaft rotation direction of tightening by hand. Then a small iron bar into or withstand the eccentric sleeve counterbore. To hand hammer along the axis of rotation direction percussion small iron bar. So that the socket head cap screws the eccentric sleeve securely installed, the last eccentric locking sleeve.
4. Fixed bearing bolts do not tighten, let the bearing jacket can rotate within the bearing housing. Then bearing seat bolt tightening. Also installed with the bearing and the seat of the other end of a shaft, the shaft several turns, the bearing itself automatically find the positive position.
5. Topcoat lubricants bearing and bearing with the bearing into the bearing housing. Then assembled with bearings and bearing sleeve on the shaft. Pushed to the desired position for installation.
6. Before installing the bearing to the shaft bearing jacket, you must unplug the fixed pin journal surface sanded smooth clean and oiled journal at the rust and lubricating (allows the bearing slightly rotating the shaft).撤消修改
