Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of four-line column roller bearing of external diameter band sealing.
Background technique
Bearing is made up of inner ring, outer ring, a plurality of roller and retainer usually; After a plurality of rollers are installed in the pocket hole that keeps corresponding on the stand respectively; Place in the raceway that constitutes by inner ring and outer ring; The retainer lid is fixed on the upper-end surface that keeps stand, and the both sides, outer ring of four-line column roller bearing have outer loose rib; Roller bearing is a kind of major criterion and the non-standard component of mechanical industry, and the structure of bearing has direct influence to working life of bearing, product precision, machine operation efficient etc., damages roller bearing in the past, is mostly serious because of bearing wear, the life-span short.Traditional four-line column roller bearing is mainly used in the cold-rolling equipment back-up roll, uses the pressure of oil spout to send oil system, and oil nozzle is installed; The diameter of oil nozzle generally is about 2.5mm; Traditional four-line column roller bearing is used for this and is furnished with the back-up roll that pressure send the cold-rolling equipment of oil system, because lubricated and dispel the heat insufficiently, burn appears in rolling surface too early to be damaged; Cause a whole set of bearing to be scrapped in advance, bearing life can't meet the demands.
The model utility content
The purpose of the utility model provides the four-line column roller bearing of a kind of high lubricating effect, fast cooling external diameter band sealing.
The technological scheme that adopts is:
A kind of four-line column roller bearing of external diameter band sealing; Comprise inner ring assembly, outer coil assembly, four-row cylindrical roller and retainer assembly; Inner ring assembly comprises first inner ring and second inner ring; Outer coil assembly comprises first outer ring and second outer ring; The retainer assembly comprises first retainer, second retainer, the 3rd retainer and the 4th retainer; First line column roller and secondary series cylindrical roller be installed in respectively first keep stand and second to keep in the pocket hole corresponding on the stand after, first keeps stand and second to keep stand to place respectively in first raceway and second raceway that is made up of first inner ring and first outer ring, first retainer lid is separately fixed at first with second retainer lid and keeps on the lower end surface of the stand and the second maintenance stand; After three-row cylindrical roller and four-row cylindrical roller are installed in the pocket hole corresponding on the 3rd maintenance stand and the 4th maintenance stand respectively; The 3rd keeps stand and the 4th to keep stand to place respectively in the 3rd raceway and the 4th raceway that is made up of second inner ring and second outer ring, and the 3rd retainer lid and the 4th retainer lid are separately fixed at the 3rd and keep stand and the 4th to keep on the upper-end surface of stand, and first inner ring docks with second inner ring; First outer ring and the second outer ring seam crossing corresponding with first inner ring and the second inner ring joint are provided with outer guide ring; Outer guide ring closely is connected first outer ring with second outer ring, is provided with loose rib outside first in the upper end of first outer ring, is provided with loose rib outside second in the lower end of second outer ring;
Neutral position in first outer ring and second outer ring of bearing; Circumferencial direction along first outer ring and second outer ring offers a plurality of oilholes respectively; The a plurality of copper plugs of difference interference fit at a plurality of oilholes place, a plurality of copper are offered two oilholes that mate with the oil nozzle diameter beyond the Great Wall respectively, and oil nozzle arrives gap between roller, retainer and the interior raceway through bearing copper oilhole beyond the Great Wall with oil spurts; Along the bearing circumferencial direction a plurality of oil inlet holes are arranged; Make oil content flow to bearing inside everywhere, send oil, offer groove respectively on the bearing outer ring corresponding with the upper and lower both sides of the oil inlet hole of the corresponding bearing of equipment oil nozzle for guaranteeing pressure; Groove is embedded in the O RunddichtringO, and oil-air lubrication pressure is not revealed.
The advantage of the utility model is:
1, the utility model is in the bearing outer ring neutral position, oilhole place along the circumferential direction, and interference fit copper plug, copper bore two oilholes with oil nozzle diameter coupling beyond the Great Wall, along the bearing outside diameter circumferencial direction a plurality of copper plugs are arranged, thereby guarantee the smooth and easy, abundant of lubricated and heat radiation.
2, the both sides of copper plug are provided with groove on the bearing outside diameter of the utility model, and groove is embedded in the O RunddichtringO, and oil-air lubrication pressure is not revealed, thereby have guaranteed maximum heat radiation, lubricated, cleaning performance.
