Description
Technical field
The present invention relates to machinery field, specifically a kind of bearing is more specifically a kind of rolling mill with bearing axial force
Bearing.
Background technology
In rolling machinery, roll bearing multiselect is with a bearing for bearing radial load and one for bearing axis
To the bearing of load.Two bearing fits use, when axial force is larger, multiselect biserial tapered roller thrust bearing or biserial
Cylindrical roller thrust bearing is as the bearing for bearing axial load.But inevitably there is roller during the rolling process in roll
Phenomenon.At this moment the case where unbalance loading, unbalance stress will occur in bearing, and bearing is caused the phenomenon that premature failure occur, give steel rolling mill's band
To bother and lose.
Invention content
The technical problem to be solved by the present invention is to：A kind of biserial spherical roller thrust bearing with aligning function is provided,
When there is roller in roll operation process bearing can uniform force, work well, improve bearing service life.It solves above-mentioned
Technical problem the technical solution adopted is that：
A kind of milling train biserial spherical roller thrust bearing, including seat ring, blowout patche, outer ring spacer, roller, retainer；It is described
Seat ring, blowout patche raceway are all spheric, and the shape of roller is provided accordingly to spheric, and roller sphere curvature radius is inside and outside rolling
0.98-0.99 times of road radius of curvature；Rib, double raceways are arranged in the blowout patche；Retainer is set between blowout patche and seat ring, and roller is set
It sets in the pocket hole of retainer or is enclosed on retainer；Roller and seat ring raceway contact angle are 60-80 °；Outer ring spacer setting exists
Between the radial outside of blowout patche, two seat rings.
Groove is arranged in one end of bearing housing, and outer ring and outer ring spacer are embedded in the groove, and the other end of bearing housing is arranged
Cover board, the cover board are fixed by screws on bearing housing；The gland compresses seat ring, and two seat rings clamp outer ring spacer solid
It is fixed.
End-play between roller and blowout patche is adjusted by changing outer ring spacer width.
The beneficial effects of the invention are as follows：1) seat ring, blowout patche raceway use spheric structure, and bearing is made to have certain aligning
Performance, aligning angle a is up to 5 ° or even bigger.2) there are one larger contact angle a for roller and raceway, and the bearing is made to have very
Big axial load ability can compare favourably with the biserial tapered roller thrust bearing of identical size.3) this structure can be eliminated
The influence of roll roller extends bearing service life, improves the economic benefit of Metallurgical Enterprise.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the position relationship schematic diagram of bearing housing and bearing；
In figure：1- seat rings, 2- blowout patches, 3- rollers, 4- retainers, 5- outer ring spacers, 6- glands, 7- bearing housings.
Specific implementation mode
Patent specific implementation mode of the present invention is described further below in conjunction with the accompanying drawings:
As shown in Figure 1, the present invention includes 2 seat rings, 1,1 blowout patche 2,3, two, the two row roller outer ring spacer of retainer 4,1
5.The raceway 11 of the seat ring 1, the raceway 21 of blowout patche 2 are all the spheric that radius is R, and the shape of roller 3 is provided accordingly to
Spheric；Roller sphere curvature radius is 0.98-0.99 times of inner and outer ring raceway radius of curvature；Rib 22 is arranged in the blowout patche 2, double
Raceway 21；Retainer 4 is set between blowout patche 2 and seat ring 1, and roller 3 is arranged in the pocket hole of retainer 4, another structure is to protect
The pocket hole for holding frame is interconnected, and forms an annulus, and roller is closed in the annulus, that is to say, that roller 3
It is closed on retainer 4；Contact angle a between 1 raceway of roller 3 and seat ring is 60-80 °；The radial direction in blowout patche is arranged in outer ring spacer
Between outside, two seat rings.Contact angle refers to the angle of roller and the tangent line and bearing axis of seat ring raceway contact point, described to cut
Line intersects with roller axis and bearing axis intersection point, and such as the angle a in Fig. 1, the angle is bigger, and axial load ability is higher.In bearing
In operation process, two row rollers are respectively subjected to the axial force of different directions, and when roller occurs in roll, spherical roller can be in ball
Sliding is automatically adjusted on the raceway of face, and bearing is kept to run well.
End-play between roller and blowout patche is adjusted by changing outer ring spacer width.
As shown in Fig. 2, groove is arranged in one end of bearing housing 7 when installation, outer ring 1 and outer ring spacer 5 are embedded in the groove, axis
The other end setting cover board 6 of case 7 is held, the cover board is fixed by screws on bearing housing；The gland 6 compresses seat ring 1,
Outer ring spacer 5 is fixedly clamped by two seat rings 1.
