Abstract
The invention discloses a self-aligning roller bearing based on novel cages. Annular grooves are disposed in the positions towards an outer ring (2) of the cages (6) in the direction of the bearing bore diameter. The grooves are not higher than the position of the intersectant center line of two surface jaws of the cages. The novel cages provided by the invention are improvement of previous CA type integrated cages. The grooves are disposed in the outer diameter of the cages and the depth of the grooves is not more than the intersectant center line of two surface jaws. The novel cages can increase the oil storing amount largely, thus the improving lubrication property of the bearing and prolonging the lubricating time. The grooves are disposed in the cages so that the using amount of copper is reduced, thus reducing the manufacturing cost.
Description
Technical field
The present invention relates to technical field of bearings.
Background technique
Selfaligning roller bearing is by two raceway inner rings, a spherical raceway outer ring, and two row's spherical rollers and retainer form.Outer raceway center is consistent with bearing centre, has self-aligning function, to axle with respect to the inclination of bearing support and the distortion of axle or bend-insensitive.Except bearing very high radial load and impulsive load, also can bear certain bi-directional axial load.
As shown in Figure 1, the selfaligning roller bearing of prior art, comprises outer ring 01, inner ring 02, aligning roller 04, and retainer 06.The middle part of outer ring 01 offers oil duct, is communicated to roller 04 and retainer 06 place.
Summary of the invention
The present invention aims to provide a kind of lubricated good
In order to achieve the above object, the invention provides a kind of selfaligning roller bearing based on novel retainer, it is characterized in that, retainer 06 just offers annular groove to the position of outer ring 02 oil duct towards bearing bore diameter direction.
Under optimal way, described depth of groove is lower than the crossing position of center line of two sides pawl that equals retainer 06.
The present invention is only aimed at the improvement of CA type integrated cage in the past as the novel retainer of selfaligning roller bearing.On retainer external diameter, add Baltimore groove, and the Baltimore groove degree of depth is no more than on the crossing center line of two sides pawl.The novel retainer of the present invention has increased oil reserve greatly, thereby has increased lubricity and the lubrication time of bearing.Because plant the change of Novel bearing retainer interpolation groove, reduced the use to copper, so reduced manufacture cost.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of prior art selfaligning roller bearing.
Fig. 2 is the cross-sectional view of selfaligning roller bearing of the present invention.
Embodiment
Selfaligning roller bearing of the present invention as shown in Figure 2, comprises outer ring 01, inner ring 02, aligning roller 04, and retainer 06.The middle part of outer ring 01 offers oil duct, is communicated to roller 04 and retainer 06 place.The present invention improves and is, retainer 06 just offers annular groove (A place in figure) to the position of outer ring 02 oil duct towards bearing bore diameter direction.Described depth of groove is lower than the crossing position of center line of two sides pawl that equals retainer 06.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technological scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
Claims (2)
1. the selfaligning roller bearing based on novel retainer, is characterized in that, retainer (06) just offers annular groove to the position of outer ring (02) oil duct towards bearing bore diameter direction.
2. the selfaligning roller bearing based on novel retainer according to claim 1, is characterized in that, described depth of groove is lower than the crossing position of center line of two sides pawl that equals retainer (06).
