Abstract
The utility model discloses a self-aligning roller bearing, which comprises an inner ring and an outer ring, and further comprises two rows of elliptical cylindrical rollers, wherein the elliptical cylindrical rollers are mounted between the inner ring and the outer ring through a retainer. The self-aligning roller bearing has good self-aligning performance, and can properly change the radian of the cambered surface on the inner wall of the outer ring and the rotation of the rollers relative to the inner ring and the outer ring to adjust the flexibility of the bearing swing and the distribution of the axial load capacity and the radial load capacity according to different environments, so that the bearing can work most perfectly in the use environment.
Description
Technical field
The utility model relates to a kind of mechanical parts, particularly a kind of selfaligning roller bearing.
Background technique
In the prior art; Bearing is divided into tapered roller bearing, roller bearing and ball bearing, and every kind of bearing has different functions when on equipment, using, as axial load resistant, anti-radial load or anti-axially and connected load radially or sliding friction changed into rolling friction; According to the required type of bearing and the size of size selected of different working environments; Since the restriction of service condition or processing conditions etc., the center of bearing hole center and axle, the angle that coaxality is relatively poor, formation is little; Using common bearing with this understanding, all is extremely disadvantageous to the each several part part in bearing and even the bearing.
The model utility content
To the deficiency that exists in the existing technology, the purpose of the utility model is to provide a kind of selfaligning roller bearing that has the aligning function and can significantly prolong bearing life.
The technological scheme of the utility model is achieved in that
Selfaligning roller bearing comprises inner ring and outer ring, also comprises two row cylindroid rollers, and said cylindroid roller is installed between said inner ring and the outer ring through retainer.
Above-mentioned selfaligning roller bearing has two row slot rollings on the said retainer, the quantity of every row slot rolling is identical with the quantity of said holder cylindrical roller.
Above-mentioned selfaligning roller bearing, said outer ring inwall is a concave arc surface.
Above-mentioned selfaligning roller bearing, said inner ring are provided with two row raceways, and said raceway and rib joint have grinding undercut.
Above-mentioned selfaligning roller bearing, the quantity of the said cylindroid roller of every row is at least 3.
Above-mentioned selfaligning roller bearing, the said cylindroid roller of every row is 36.
Above-mentioned selfaligning roller bearing, each said cylindroid roller corresponding setting is in a slot rolling.
Above-mentioned selfaligning roller bearing, said cylindroid roller both ends of the surface center all has depression.
Above-mentioned selfaligning roller bearing has U type groove on the said outer ring.
Above-mentioned selfaligning roller bearing has oilhole in the bottom of said U type groove.
The beneficial effect of the utility model is: selfaligning roller bearing has good aligning property; But and adjust the flexibility of bearing swing and the distribution of axial load ability and radial load ability according to the radian of varying environment appropriate change outer ring inwall cambered surface and spin rotating between inner ring and outer ring, make bearing in Environmental Conditions, to work with the most perfect situation.

Embodiment
In conjunction with accompanying drawing the utility model is done further explanation:
As shown in Figure 1, selfaligning roller bearing comprises inner ring 1 and outer ring 2; Also comprise two row cylindroid rollers 3, said outer ring 2 inwalls are concave arc surface, and said inner ring 1 is provided with two row raceways 6; Said raceway 6 has grinding undercut 8 with rib 7 joints, and the said cylindroid roller 3 of every row is 36, and is as shown in Figure 2; Said cylindroid roller 3 both ends of the surface centers all have depression 9, and depression 9 can reduce the stress concentration phenomenon at roller edge, prolong the working life of roller; Said cylindroid roller 3 is installed between said inner ring 1 and the outer ring 2 through retainer 4, and is as shown in Figure 4, and said retainer 4 comprises two row slot rollings 5; As shown in figures 1 and 3, the said cylindroid roller 3 of two row is separately positioned in the said slot rolling 5, and motion by a small margin can be carried out in said cylindroid roller 3 relative outer rings 2; To reach self-adjusting purpose; Adapt to the angle between bearing hole center and the axle center, thereby make bearing to run well, but and adjust the flexibility of bearing swing and the distribution of axial load ability and radial load ability according to the radian of varying environment appropriate change outer ring 2 inwall cambered surfaces.
Have U type groove 10 on the said outer ring, have oilhole,, make bearing operation more flexible through U type groove 10 and oilhole 11 lubricating oil filling in bearing in the bottom of said U type groove 10.
The foregoing description only be for clearly explain the utility model create done for example, and be not the qualification of the utility model being created embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.Any conspicuous variation of being extended out within all spirit and principles at the utility model or change still are in the utility model and create among the protection domain of claim.
