Abstract
The utility model discloses a four-row cylindrical roller bearing for high speed rolling mill, which comprises two pairs of split type inner rings (1) and outer rings (2), which are symmetrical, and cylindrical rollers (3) arranged between the inner rings (1) and the outer rings (2), wherein the cylindrical rollers (3) are limited in a holder (6). Outer spacer rings (4) and inner spacer rings (5) are arranged between the inner rings (1) and the outer rings (2), arc oil grooves are arranged on the end surfaces of both sides of the inner and the outer rings in the radial direction, annular oil grooves are respectively opened on the middle portion of each outer ring external cylindrical surface around the cylindrical surface, oil through holes which are along the radial direction of the bearing are uniformly distributed in the annular oil grooves along the circumferential direction, furthermore, through holes are uniformly distributed on the middle portion of the holder (6) along the circumferential direction, oil holes are uniformly distributed on the middle portions of the external cylindrical surfaces of the outer spacer rings (4) along the circumferential direction, and the oil holes are communicated to the space between the two rows of rollers on both sides and the inner spacer rings (5). The bearing of the utility model aims at increasing the lubricating performance of the bearing to bear bigger radial loading.
Description
Technical field
The present invention relates to a kind of four-line column roller bearing.
Background technique
Four-line column roller bearing is widely used in various milling trains at present, and four-row cylindrical roller bearing for rolling mill can bear bigger radial load, but the bearing rotating speed is limited, can not satisfy high mill speed and required precision.
Summary of the invention
The present invention has aimed to provide a kind of four-line column roller bearing that uses on fast mill, be intended to strengthen the greasy property of bearing, so that bear big radial load.
A kind of four-row cylindrical roller bearing for high-speed rolling mill of the present invention comprises the split type inner ring of two pairs of symmetries, split type outer ring, and each two cylindrical roller to being provided with between inner ring and the outer ring, and these two cylindrical rollers are limited in the retainer.Wherein, be provided with outer ring spacer and the cone spacer that is nested with one heart between the two pairs of inner rings and the outer ring; Each inner ring and both sides, outer ring end face have been disposed radially the circular arc oil groove; The middle part of each outer ring external cylindrical surface offers annular oil groove around cylinder, along the circumferential direction is evenly equipped with in circular groove along the oil through of bearing radial direction; Oil through passes to the space between two line column rollers.In addition, each retainer middle part along the circumferential direction is evenly equipped with along the through hole of bearing radial direction; The outer cylinder middle part of outer ring spacer along the circumferential direction is evenly equipped with along the oilhole of bearing radial direction; Oilhole passes to the space between two rows of rollers at two sides and the cone spacer.
Under the optimal way, above-mentioned oil through, through hole and oilhole along the circumferential direction are provided with 6 respectively.The outer diametric plane of retainer also can be designed to a plurality of oilholes, is not only limited to 6, thereby guarantees can access in the bearing operation process lubricated fully.
Bearing of the present invention has following advantage:
1, can to bear bigger radial load, limit speed and precision very high for this bearing, is applicable to the rolling bearing of finishing mill.
2, the lubricating system that adopts of bearing has taken into full account the run up problem of the lubricated and heat radiation that brings of bearing, 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 be bearing of the present invention partly cut open structural representation; Omit the Lower Half structure of symmetry among the figure.
Among the figure: 1, inner ring; 2, outer ring; 3, roller; 4, outer ring spacer; 5, cone spacer; 6, retainer.
Embodiment
A kind of as shown in Figure 1 four-row cylindrical roller bearing for high-speed rolling mill comprises split type inner ring 1, the split type outer ring 2 of two pairs of symmetries, and each two cylindrical roller 3 to being provided with between inner ring 1 and the outer ring 2; Two cylindrical rollers are limited in the retainer 6.Be provided with outer ring spacer 4 and the cone spacer 5 that is nested with one heart between the two pairs of inner rings 1 and the outer ring 2.Each inner ring and both sides, outer ring end face have been disposed radially the circular arc oil groove; The middle part of each outer ring external cylindrical surface offers annular oil groove around cylinder, along the circumferential direction is evenly equipped with in circular groove along the oil through of bearing radial direction; Oil through passes to the space between two line column rollers.In addition, each retainer 6 middle part along the circumferential direction is evenly equipped with along the through hole of bearing radial direction.The outer cylinder middle part of outer ring spacer 4 along the circumferential direction is evenly equipped with along the oilhole of bearing radial direction; Oilhole passes to the space between two rows of rollers at two sides and the cone spacer 5.
Under the optimal way, above-mentioned oil through, through hole and oilhole along the circumferential direction are provided with 6 respectively.Retainer is outer can be designed to a plurality of oilholes, is not only limited to 6, thereby guarantees can access in the bearing operation process lubricated fully.
Claims (2)
