Abstract
A kind of band base spherical outside surface angular contact ball bearing, comprise bearing support and angular contact ball bearing, it is characterized in that: described bearing support offers bearing mounting hole, the internal surface of this bearing mounting hole is inner ball surface; Described angular contact ball bearing comprises the outer ring and inner ring that offer annular channel and the ball be located between inner ring and the annular channel of outer ring, wherein, the outer surface of described outer ring is outer spherical surface, and the outer spherical surface of outer ring coordinates with the inner ball surface of the bearing mounting hole on bearing support.The band base spherical outside surface angular contact ball bearing of the present invention, both radial load can be born, also thrust load can be born, or bear radial and axial connected load simultaneously, also can bear certain tilting moment simultaneously, and when being subject to tilting moment, carry out self-aligning correction by the outer spherical surface of its outer ring and the inner ball surface of bearing mounting hole, do not need to increase Bearing inner burden.
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 rolling bearing and bearing support combined, and are used widely because it is easy to install, footprint is little and maintenance cost is low.The bearing core of existing ball bearing of usheing to seat mostly is deep groove ball bearing with spherical outer surface and distressed structure thereof, be mainly used to bear radial load and a small amount of thrust load.In practical application, if installation shaft inclination bigger than normal or there is major axis amount of deflection, bending time, larger axis can be produced to power or tilting moment, bearing will be caused to damage fast.Thus be necessary for kind of bearings application demand, provide one to bear radial load, the rolling bearing units unit of thrust load can be born again.
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, comprise bearing support and angular contact ball bearing, described bearing support offers bearing mounting hole, the internal surface of this bearing mounting hole is inner ball surface; Described angular contact ball bearing comprises the outer ring and inner ring that offer annular channel and the ball be located between inner ring and the annular channel of outer ring, wherein, the outer surface of described outer ring is outer spherical surface, the outer spherical surface of outer ring coordinates with the inner ball surface of the bearing mounting hole on bearing support, the bearing mounting hole of described bearing support is vertically in unsymmetrical, and this bearing mounting hole has thicker hole wall in the side of the line of the point of contact closer to described ball and inside and outside circle annular channel.
The band base spherical outside surface angular contact ball bearing of the present invention, both radial load can be born, also thrust load can be born, or bear radial and axial connected load simultaneously, also can bear certain tilting moment simultaneously, and when being subject to tilting moment, self-aligning correction is carried out by the outer spherical surface of its outer ring and the inner ball surface of bearing mounting hole, do not need to increase Bearing inner burden, bearing capacity is large, good rigidly.
The present invention improves 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 circle annular channel and bearing radial plane, this bearing contact angle a is between 35 ° ~ 45 °.Larger thrust load can be born.
Distance between above-mentioned outer ring raceway center and bear inner ring grooved railway center to its place circle body both ends of the surface is asymmetrical shape, and outer ring and inner ring all have thicker axial thickness in the side of the line of the point of contact near described ball and inside and outside circle annular channel.When bearing bears thrust load or radial and axial connected load, there is larger bearing capacity and supporting rigidity.
The center of ball described above and the circular arc peak of outer ring outer spherical surface are positioned at same radial plane, between the radial plane at now the circular arc peak of outer ring outer spherical surface and the ditch center-of-curvature line place of raceway groove disposed thereon, there is axial distance δ, when bearing bears tilting moment because of installation shaft inclination or major axis amount of deflection, can correct by aligning smoothly.
Accompanying drawing illustrates:
Fig. 1 is plan view of the present invention.
Fig. 2 is the A--A cut-away view of Fig. 1.
Fig. 3 is that outer ring coordinates the partial enlarged drawing assembled with bearing support.
Embodiment:
As shown in Figure 1, 2, a kind of band base spherical outside surface angular contact ball bearing, comprise bearing support 1 and angular contact ball bearing 2, described bearing support 1 offers bearing mounting hole 11, the internal surface of this bearing mounting hole 11 is inner ball surface; Described angular contact ball bearing 2 comprises the outer ring 21 and inner ring 22 that offer annular channel and is located at ball 23 between inner ring and the annular channel of outer ring, wherein, the outer surface of described outer ring 21 is outer spherical surface, and the outer spherical surface of outer ring coordinates with the inner ball surface of bearing mounting hole.Described ball 23 is with interior, a bearing contact angle a is formed between the line of the point of contact of outer ring annular channel and bearing radial plane, this bearing contact angle a is between 35 ° ~ 45 °, the center 230 of described ball 23 is positioned at same radial plane with the circular arc peak 211 of outer ring 21 outer spherical surface, between the radial plane at the circular arc peak 211 of outer ring outer spherical surface and ditch center-of-curvature line 210 place of raceway groove disposed thereon, there is axial distance δ, the size of δ value is by following formulae discovery: δ=(Re-Dw/2) sina, (Re is outer ring raceway radius of curvature, Dw is ball diameter).
In addition, the bearing mounting hole 11 of described bearing support 1 is vertically in unsymmetrical, and this bearing mounting hole 11 is in having thicker hole wall closer to described ball 23 with the side of the line of the point of contact of inside and outside circle annular channel.Distance between outer ring 21 channel center and inner ring 22 channel center to its place circle body both ends of the surface is asymmetrical shape, and outer ring 21 and inner ring 22 are all in having thicker axial thickness near described ball 23 with the side of the line of the point of contact of inside and outside circle annular channel.
The foregoing is only preferred embodiment of the present invention, be not used for limiting scope of the invention process, all equal changes of doing according to the scope of the claims of the present invention and modification, all fall into the scope that patent of the present invention contains.
