First, SKF bearing accessories common sense slanting ring (separable): a separable "L"-shaped cross-section of the ring; with some outside as a centripetal cylindrical roller SKF bearing inner ring of a rib.
Flat retaining ring: a detachable substantially flat washer; some inside or outside as a circumferential cylindrical roller SKF bearing outer ring or inner ring of a rib.
Stop ring: a single-mouth ring with a stable cross section; installed in the annular groove; axially positioning the tumbling SKF bearing in the housing or on the shaft.
Middle retaining ring: a separable ring in a roller SKF bearing with two or more rows of rollers; used to block two rows of rollers and guide the rollers.
Spacer: is a ring-shaped part; used between two SKF bearing rings or SKF bearing washers; or between two halves of SKF bearing rings or between two halves of SKF bearing washers; so that they adhere to the regular axial direction interval.
Sealing ring: An annular cover consisting of one or several parts; fixed on a ferrule or washer of an SKF bearing and touching or forming a narrow labyrinth gap with another ring or washer; avoiding leakage of lubricating oil and invasion of foreign objects.
Dust cover: is a ring cover; usually stamped from a thin metal plate; fixed on a ferrule or washer of the SKF bearing; and extended toward the other ring or washer; covers the internal space of the SKF bearing; but not with another A set of rings or washers to touch.
Locking ring: a single-mouth ring with a stable cross-section; installed in the annular groove as a retaining ring to hold the roller or the retaining frame in the SKF bearing.
Roller: A ball or roller that rolls between raceways.
Persistence: SKF bearing parts that are partially wrapped with some or more tumblers; and moved with them; used to block the roll; and usually guide the roll and hold it in the SKF bearing.
Retaining ring: A part attached to the inner ring or the shaft ring; the centrifugal force is used to enhance the ability of the rolling SKF bearing to avoid foreign matter intrusion.
Second, the coupling is installed in the process of coupling disassembly; the most difficult task is to remove the hub from the shaft. The hub of the key connection; usually with three-legged pull or four-leg pull pull. The puller should match the shape of the wheel; the right angle hook of each foot of the horse should be suitable for the connection with the rear side of the wheel; the slipping fantasy will not occur when the force is applied. This method is only used for the opening of the smaller than the interference. About the wheel with a larger interference ratio; often use the heating method; perhaps cooperate with the hydraulic jack to disassemble.
The removal, finishing and quality assessment of all parts of the coupling is an extremely important task after the coupling is disassembled. The evaluation of the parts means that each part is after work; its scale, shape and nature of the data. The current situation is compared with the quality standards determined by the parts; it is determined which parts can be used continuously; which parts should be corrected and used; which are attributed to the parts that should be renewed.
When disassembling the coupling, the coupling bolts are usually removed first. Due to the accumulation of a layer of grease, corrosive products and other deposits on the outer surface of the thread; the bolts are not easy to disassemble; especially for the bolts with severe corrosion; it is very difficult to disassemble. It is necessary to pick the right things for the disassembly; the stress on the outer hexagon or the inner hexagon of the bolt is now slipped and damaged; it is more difficult to disassemble the meeting. The bolts that are now more corroded or greased; often with solvents (such as Loose rust agent) Spray the joint between the bolt and the nut; let the solvent enter the thread; this will be easily disassembled.
