Abstract
A self-aligning ball bearing comprises a bearing outer ring, a bearing inner ring, and rolling bodies. The outer ring of the bearing sleeves outside the inner ring of the bearing, and the inner surface of the inner ring of the bearing and the outer surface of the inner ring of the bearing form a pair of opposite circumferential surfaces, the inner surface of the outer ring of the bearing is provided with an arc track, the outer surface of the inner ring of the bearing is provided with a plurality of a circular grooves, the rolling bodies are clamped between the arc track and circular grooves, and a retaining frame used for fixing the rolling bodies is arranged between the outer ring and bearing inner ring of the bearing. According to the self-aligning ball bearing, the inner surface of the outer ring of the bearing adopts an arc-shaped spherical surface, and two or more rows of steel balls are arranged in the bearing, so that the alignment of an axis and a supporting seat hole can be greatly adjusted, and the self-aligning capability is strong; the retaining frame has a chrysanthemum shape and good fixing effect, so that the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to technical field of bearings, especially a kind of selfaligning ball bearing.
Background technique
Selfaligning ball bearing has cylindrical hole and two kinds of structures of conical bore, and the material of retainer has steel plate, synthetic resin etc.Be characterized in that outer ring raceway is spheric, there is self-aligning, can compensate nonconcentricity and make with shaft deflection the error that selfaligning ball bearing becomes, but its inside and outside circle relative tilt degree must not surpass 3 degree.Article two, between the outer ring that the inner ring of raceway and raceway are sphere, be equipped with the bearing of spherical shape ball.The centre of curvature of outer ring raceway face is consistent with bearing centre, so have the aligning function same with self-aligning ball bearing.When there is deflection in axle, shell, can automatically adjust, do not increase bearing burden, selfaligning roller bearing can bear the axial load of radial load and two directions.Radial load ability is large, is applicable to the situation of heavy load, impact load.

Above-mentioned a kind of selfaligning ball bearing, described arc track and arc groove are all along circumferentially extending.
Above-mentioned a kind of selfaligning ball bearing, the quantity of described arc groove is 2.
Above-mentioned a kind of selfaligning ball bearing, the circle hole of described bearing inner race is cylindrical hole.
Above-mentioned a kind of selfaligning ball bearing, the circle hole of described bearing inner race is conical bore.
Above-mentioned a kind of selfaligning ball bearing, described retainer is chrysanthemum shape retainer.
Above-mentioned a kind of selfaligning ball bearing, described bearing outer ring internal surface, bearing inner race outer surface, chrysanthemum shape retainer place all scribble oil layer.
Above-mentioned a kind of selfaligning ball bearing, described rolling element is steel ball.
Beneficial effect of the present invention is: bearing outer ring internal surface adopts arc sphere, in bearing, be provided with steel balls more than two rows, can adjust greatly the centering in axis and supporting base hole, self-aligning ability is strong, retainer is chrysanthemum shape retainer, retainer good fixing effect, has strengthened working life of bearing.
Accompanying drawing explanation
