The invention discloses a kind of spheric roller bearings, and including bearing block, bearing outer ring, spherical roller, retainer, bearing inner race, dustproof cover, the first fixed plate, bolt hole and the second fixed plate, bearing outer ring and bearing inner race are provided on the bearing block；Retainer is fixed between the bearing outer ring and bearing inner race；Spherical roller is provided on the retainer；The both sides of edges of the bearing outer ring and bearing inner race is each to fix a dustproof cover；First fixed plate is fixed in one end of the bearing block；The other end of the bearing block fixes second fixed plate.The advantageous effect of the invention is that the inner ring of spheric roller bearing can be rotated freely around the axis of oneself, has automatic aligning performance and can bear radial direction heavy load and impact load.
Description
Technical field
The invention belongs to technical field of bearings, and in particular to a kind of spheric roller bearing.
Background technology
General wind-force mainshaft bearing has former and later two, the power that main shaft bearing is born mainly have fan blade and wheel hub weight,
Wind acts on the power of main shaft by wind wheel, thus main shaft bearing is primarily subjected to radial load, also by the axial direction generated due to wind-force
Power, due to the variation of wind-force, the turbulent flow of wind, main shaft can generate bending, swing, it is desirable that main shaft bending also can normally turn when tilting
It is dynamic, that is to say, that the aligning performance that bearing must have, so will use to spheric roller bearing.
Current bearing inner race can not be rotated freely around the axis of oneself, without automatic aligning performance and cannot be held
By radial direction heavy load and impact load.
Therefore, a kind of spheric roller bearing is invented to be very necessary.
The content of the invention
It is an object of the invention to provide a kind of spheric roller bearing, to solve to propose current axis in above-mentioned background technology
Holding inner ring can not rotate freely around the axis of oneself, without automatic aligning performance and cannot bear radial direction heavy load and punching
The problem of hitting load.
To achieve the above object, the present invention provides following technical solution：A kind of spheric roller bearing, including bearing block, axis
Bearing outer-ring, spherical roller, retainer, bearing inner race, dustproof cover, the first fixed plate, bolt hole and the second fixed plate, the bearing
Bearing outer ring and bearing inner race are provided on seat；Retainer is fixed between the bearing outer ring and bearing inner race；The holding
Spherical roller is provided on frame；The both sides of edges of the bearing outer ring and bearing inner race is each to fix a dustproof cover；The bearing
First fixed plate is fixed in one end of seat；The other end of the bearing block fixes second fixed plate.
Further, bolt hole there are two being set in first fixed plate.
Further, bolt hole there are two being set in second fixed plate.
Further, the inner circumferential of the outer ring of the spheric roller bearing is spherical surface, and the centre of sphere is in the center of bearing, formation rolling
Road, and bearing has two row spherical rollers, shares the spherical raceway of outer ring, and roller is in cydariform, drum surface and spherical outer ring raceway phase
It coincide.
Further, the spherical roller is provided with two row, and corresponding arrangement, has two raceways in bearing inner race, with axis
Bearing axis tilts angled.
The technique effect and advantage of the present invention：The spheric roller bearing, as plain bearing, spheric roller bearing is main
It is made of bearing outer ring, spherical roller, retainer and bearing inner race, is mainly characterized by spherical roller and the raceway formed not
Together, the inner circumferential of the outer ring of spheric roller bearing is spherical surface, and the centre of sphere has two row balls in the center of bearing, formation raceway, bearing
Face roller shares the spherical raceway of outer ring, and roller is in cydariform, and drum surface matches with spherical outer ring raceway, and spherical roller is provided with
Two row, and corresponding arrangement, have two raceways in bearing inner race, and angled, two row spherical rollers are tilted with bearing axis
It can not only be rotated around bearing axis, moreover it is possible to be rotated with bearing centre, realize that inner ring can be rotated freely around the axis of oneself, make
The spheric roller bearing is obtained with automatic aligning performance, since roller contact with inner ring outer ring is that line is not a little, it is possible to
Bear radial direction heavy load and impact load.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment belongs to the scope of protection of the invention.
The present invention provides a kind of spheric roller bearing as shown in Fig. 1 and Fig. 2, including bearing block 1, bearing outer ring 2,
Spherical roller 3, retainer 4, bearing inner race 5, dustproof cover 6, the first fixed plate 7,8 and second fixed plate 9 of bolt hole, the bearing
Bearing outer ring 2 and bearing inner race 5 are provided on seat 1；Retainer 4 is fixed between the bearing outer ring 2 and bearing inner race 5；Institute
It states and spherical roller 3 is provided on retainer 4；The both sides of edges of the bearing outer ring 2 and bearing inner race 5 is each to fix a dustproof cover
6；First fixed plate 7 is fixed in one end of the bearing block 1；The other end of the bearing block 1 fixes second fixed plate
9。
Further, bolt hole 8 there are two being set in first fixed plate 7.
Further, bolt hole 8 there are two being set in second fixed plate 9.
Further, the inner circumferential of the outer ring of 3 bearing of spherical roller is spherical surface, and the centre of sphere is in the center of bearing, formation
Raceway, and bearing has two row spherical rollers 3, shares the spherical raceway of outer ring, and roller is in cydariform, drum surface and spherical outer ring raceway
It matches.
Further, the spherical roller 3 is provided with two row, and corresponding arrangement, has two raceways in bearing inner race, with axis
