A demolition
1. 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.
2. 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. Should shaft the other end of the bearing housing bolts loose, to avoid both ends of the bearing damage each other do not Jin.china bearing manufacturer
Second, the installation
1. SKF bearings must unplug the bearing jacket fixed to the shaft installation pin, the journal surface sanded smooth and clean, in a journal at the to anoint rust and lubricating (allow slightly rotating the bearings on the shaft).
2. Topcoat lubricants bearing and bearing with the bearing into the bearing housing. Then assembled bearings with SKF bearing sleeve on the shaft. Pushed to the desired position for installation.
3. Fixed bearing bolts do not tighten, let the bearing jacket can rotate within the bearing housing. Also installed with the be aring and the seat of the other end of a shaft, the shaft several turns, the bearing itself automatically find the positive position. Then bearing seat bolt tightening.
4. 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. The socket head cap screws the eccentric sleeve securely installed, the last eccentric locking sleeve
Different standard of judgment based on the mechanical properties and the degree of importance and inspection cycle. Injury, subject to the following bearings shall not be re-used and must be replaced.
1) of the bearing components in fracture and defects.high-speed bearings
2) raceway material rolling surface stripping.
In order to give full play to the SKF bearing and long-term to maintain its proper performance, you must be a really good job and regular maintenance (periodic inspection).
Appropriate periodic inspection, so that early detection of fault, to prevent accidents in the first place is very important to improve the productivity and economy.
1, cleaning:
Bearings removed for inspection, good appearance record using photography and other methods. In addition, to confirm that the remaining amount of lubricant and lubricant sampling, then cleaning bearings.
a bearing wash cleaning sub-coarse and fine cleaning, the bottom of the container and can be used to put a metal grid.
rough wash oil using a brush to remove grease or sticky materials. Oil rolling bearing, note that due to foreign object damage rolling surface.
c, sperm washing, in the oil slowly rotating bearings, should be carefully carried out.
Commonly used cleaning agent is a neutral water-f ree diesel oil or kerosene and, if necessary, are also sometimes used warm lye. Regardless of what kind of cleaning agent, must often filtered to keep clean.
Immediately after cleaning, the SKF bearings coated with anti-rust oil or rust grease.slim bearing
