Abstract
The invention discloses an outer spherical surface angle contact ball bearing with a pedestal. The bearing comprises a bearing pedestal and an angle contact ball bearing. The bearing is characterized in that a bearing installing hole is formed in the bearing pedestal; the inner surface of the bearing installing hole is an inner spherical surface; the angle contact ball bearing comprises an outer ring and an inner ring with annual channels and a ball arranged between the annual channels of the outer ring and the inner ring; the outer surface of the outer ring is an outer special surface; and the outer spherical surface of the outer ring is matched with the inner spherical surface of the bearing installing hole on the bearing pedestal. The outer spherical surface angle contact ball bearing with the block can both bear the radial load and the axial load, or the combined loads in the radial and the axial directions at the same time, furthermore can bear a certain overturning moment, and can be automatically centralized and corrected through the outer spherical surface of the outer ring and the inner spherical surface of the bearing installing hole without increasing the internal load of the bearing when being subjected to the overturning moment.
Description
Technical field:
The present invention relates to a kind of band base spherical outside surface angular contact ball bearing.
Background technique:
Rolling bearing units are bearing units that rolling bearing and bearing support are combined, and are easy to install because of it, footprint is little and maintenance cost is low is used widely.The bearing core of the existing ball bearing of usheing to seat mostly is deep groove ball bearing and the distressed structure thereof with spherical outer surface,, be mainly used to bear radial load and a small amount of thrust load.In the practical application, if the installation shaft inclination is bigger than normal or have the major axis amount of deflection, when crooked, can produce larger axis to power or tilting moment, will cause bearing to be damaged fast.Thereby be necessary for the kind of bearings application demand, provide a kind of and can bear radial load, can bear again the rolling bearing units unit of thrust load.
Summary of the invention:
The object of the present invention is to provide a kind of band base spherical outside surface angular contact ball bearing, it can bear radial load and thrust load simultaneously.
A kind of band base spherical outside surface angular contact ball bearing comprises bearing support and angular contact ball bearing, it is characterized in that: offer bearing mounting hole on the described bearing support, the internal surface of this bearing mounting hole is inner ball surface; Described angular contact ball bearing comprise outer ring and the inner ring that offers annular channel and be located at inner ring and the annular channel of outer ring between ball, wherein, the outer surface of described outer ring is outer spherical surface, and the inner ball surface of the bearing mounting hole on the outer spherical surface of outer ring and the bearing support cooperates.
The present invention's band base spherical outside surface angular contact ball bearing, both can bear radial load, also can bear thrust load, perhaps bear simultaneously radial and axial connected load, also can bear certain tilting moment simultaneously, and when being subject to tilting moment, can carry out the self-aligning correction by the outer spherical surface of its outer ring and the inner ball surface of bearing mounting hole, not need to increase the inner burden of bearing.
The present invention can improve by following scheme:
Form a bearing contact angle a between the line of the point of contact of ball described above and inside and outside ring shape raceway groove and the bearing radial plane, this bearing contact angle a is between 35 ° ~ 45 °.Can bear larger thrust load.
The bearing mounting hole of bearing support described above is unsymmetrical vertically, and this bearing mounting hole has thicker hole wall in a side of the line of the point of contact of close described ball and inside and outside ring shape raceway groove.Bearing capacity is large, good rigidly.
Outer ring raceway described above center and bear inner ring grooved railway center are asymmetrical shape to the distance between its place circle body both ends of the surface, and outer ring and inner ring all have thicker axial thickness in the side near the line of the point of contact of described ball and inside and outside ring shape raceway groove.When bearing thrust load or radial and axial connected load, bearing has larger bearing capacity and supporting rigidity.
The circular arc peak of the center of ball described above and outer ring outer spherical surface is positioned at same radial plane, this moment the outer ring outer spherical surface the circular arc peak and the radial plane at the ditch center-of-curvature line place of raceway groove disposed thereon between have axial distance δ, when bearing tilts or major axis amount of deflection when bearing tilting moment smoothly aligning correction because of installation shaft.
