Abstract
The utility model relates to a four-row cylinder roller bearing for high-speed aluminum foil mills by adopting the structure of two double-row roller bearings with an inner and an outer spacing collars, which comprises two inner rings (1), two outer rings (2), a four-row cylinder roller (3), an outer spacing collar (4), an inner spacing collar (5) and two holders (6), wherein four circular oil sinks are designed on end faces of the inner rings (1) and the outer rings (2), annular oil sinks and a plurality of oil holes are designed on external diameter faces of the outer rings (2) and the outer spacing collar (4), and a plurality of oil holes are designed on the external diameter faces of the holders (6). The bearing can bear larger radial loads with limit speed and high precision, and is applicable to roll bearings of finishing mills, the development of such bearings makes up for the deficiency of four-row cylinder roller bearings used for domestic ordinary mills, the limit speed and the precision of the bearings completely satisfy the operating conditions of user main frames, which can enhance the rolling speed and precision of main frames to a larger extent.
Description
Technical field
The utility model belongs to technical field of bearings, specially refers to a kind of high speed aluminium foil mill four-line column roller bearing.
Background technique
Four-line column roller bearing is widely used in various milling trains, three kinds of four-row cylindrical roller bearing for rolling mill such as FC, FCD, FCDP have been stipulated among China standard JB/T 5389.1, this class bearing can bear bigger radial load, but the bearing rotating speed is limited, often can not satisfy the mill speed and the required precision of fast mill, therefore need a kind of high limit rotating speed of development, high-precision four-line column roller bearing.
Summary of the invention
At above-mentioned deficiency, the utility model proposes a kind of high speed aluminium foil mill four-line column roller bearing, can bear big radial load, have high limit rotating speed, highi degree of accuracy.
For achieving the above object, the utility model has adopted following technological scheme:
Described high speed aluminium foil mill adopts two Biserial cylindrical roller bearings to add the structural type of inside and outside spacer ring with four-line column roller bearing, constitute by two inner rings, two outer rings, four-row cylindrical roller, an outer ring spacer, a cone spacer, two retainers, at inner ring and cycle surface design four circular arc oil grooves are arranged, the outer diametric plane design of outer ring and outer ring spacer has annular oil groove and a plurality of oilhole, the outer diametric plane design of retainer that a plurality of oilholes are arranged, and guarantees can access in the bearing operation process lubricated fully.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
1, can to bear bigger radial load, limit speed and precision very high for this bearing, be applicable to the rolling bearing of finishing mill, development to this bearing has remedied the deficiency of domestic conventional mill with four-line column roller bearing, bearing limit speed and precision satisfy the working condition of subscriber's main station fully, can improve the mill speed and the precision of main frame largely.
2, bearing adopts two Biserial cylindrical roller bearings to add the mode of inside and outside spacer ring, and the integral rigidity that improves bearing reaches radially bearing capacity, single biserial cylindrical bearing processing technology maturation, and precision can reach the SP level.The isoparametric phase mutual deviation of two Biserial cylindrical roller bearing sizes, play that is used for assembly, must further strictly control, thereby the pairing that guarantees two Biserial cylindrical roller bearings is used, inner ring raceway leaves certain reconditioning quality, two inner rings are loaded onto behind the roll raceway diameter of reconditioning again, thereby guarantee the concentricity of bearing and roll better, further improve the service precision of bearing.
3, bearing adopts the mode of oil-air lubrication, and each part has taken into full account the run up problem of the lubricated and heat radiation that brings of bearing in design, at inner ring, outer ring, spacer ring, retainer, have many grooves, hole etc.Groove, hole form like this lubricated, heat dissipation channel have just been formed one with the passage on bearing support, the roll and have been lubricated reliably and radiation system, on outer ring and retainer, corresponding Position Design has circular groove and a plurality of lubrication hole between two rollers, make can access in the bearing operation process lubricated fully, thereby improve the limit speed of bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among Fig. 1: 1-inner ring; 2-outer ring; 3-cylindrical roller; 4-outer ring spacer; 5-cone spacer; 6-retainer.
Embodiment
As shown in Figure 1: a kind of four-line column roller bearing that is applied to the finish foil mill work roll of the present utility model, be of a size of φ 170 * φ 230 * 180, dimensional accuracy reaches the P5 level, running accuracy reaches the P4 level, bearing end-play is 0.14～0.16, radially specified dynamic and static load reaches 700KN and 1500KN respectively, and during oil-air lubrication, bearing changes scooter 2500r/min.
Wherein, bearing inner race (1), outer ring (2) and cylindrical roller (3) material adopt army's first steel, and outer ring spacer (4) and cone spacer (5) adopt Bearing Steel, and retainer (6) adopts brass car system solid cage, and retainer (6) is guided by outer ring (1).
Bearing adopts the lubricating system of oil-air lubrication, on outer ring (1) and outer ring spacer (4), be processed with the oilhole of annular oil groove and 6 φ 4 respectively, the corresponding oilhole that radially also is processed with 6 φ 3 at retainer (6), (1), (2) two end faces of inner ring are processed with the oil groove of 4 R30 dark 3 respectively in the outer ring, and the passage on these oil grooves, oilhole and bearing support, the roll has been formed a lubricated reliably and radiation system.
Claims (1)
1, a kind of high speed aluminium foil mill four-line column roller bearing, it is characterized in that: this bearing adopts two Biserial cylindrical roller bearings to add the structural type of inside and outside spacer ring, constitute by two inner rings (1), two outer rings (2), four-row cylindrical roller (3), an outer ring spacer (4), a cone spacer (5), two retainers (6), at inner ring (1) and the design of outer ring (2) end face four circular arc oil grooves are arranged, the outer diametric plane design of outer ring (2) and outer ring spacer (4) has annular oil groove and a plurality of oilhole, the outer diametric plane of retainer (6) designs a plurality of oilholes.
