Description
Technical field
The present invention relates to technical field of bearings more particularly to a kind of double-row conical novel bearings for carrying axial force.
Background technique
The double row tapered roller bearing in milling equipment is applied, which is that an inner ring, two outer rings and one are outer
Spacer ring.For the bearing at work due to bearing axial force, the outer diameter of bearing and the cabinet inner hole of equipment are clearance fit, gap value
Generally at 0.15-2 millimeters.Radial force is undertaken by four-line column roller bearing.Therefore axis is leaned in the outer ring of double row tapered roller bearing
To positioning sleeve compress, outer ring must be fixed.But if not pressing tightly just has gap, bearing is suspended on roller at this time, when
When one column roller works, axial force is larger, and outer ring and the gap that shell cooperates are big, then the outer ring of bearing does not have with inner ring assembly
Relative rolling, but as the axis of equipment rotates together.Bearing loses rolling, bearing function.Thus make fixed equipment
There are sliding friction in positioning sleeve and outer ring, and friction seriously will cause outer ring grinding cracks.
Summary of the invention
The present invention prevents outer to solve the above problems, provide a kind of double-row conical novel bearing for carrying axial force
Circle rotates, so that the bearing capacity for solving original double row tapered roller bearing is small, rigidity is small, the service life is short and impact resistance
The disadvantages of poor.
In order to solve the above technical problems, the technical scheme is that the double-row conical Novel shaft of carrying axial force
It holds, including outer ring spacer, outer ring, roller, retainer and inner ring；Roller is tilted and is symmetrically installed on the excircle of inner ring two sides,
The both ends of inner ring are symmetrically installed with retainer, and the roller external symmetry of two sides is set with outer ring, between two outer rings by outside every
Circle is connected；The both ends circumference of outer ring spacer is equipped at least one section of arc-shaped convex, the end face circle for the outer ring being connected with outer ring spacer
Correspondence offers at least one section of circular groove on week, offers oilhole on the circumference of outer ring spacer.
Further, the arc-shaped convex of outer ring spacer is equal with the circular groove quantity of outer ring.
The present invention controls the outer ring rotating of bearing by using structures such as outer ring spacers.Bearing is set to work normally.To
The service life for extending bearing, reduces the cost.

Specific embodiment
Specific embodiments of the present invention will be further explained by 1-10 with reference to the accompanying drawing.
Carry the double-row conical novel bearing of axial force, including outer ring spacer 1, outer ring 2, roller 3, retainer 4 and interior
Circle 5；Roller 3 is tilted and is symmetrically installed on the excircle of 5 two sides of inner ring, the both ends of inner ring 5 are symmetrically installed with retainer 4,
3 external symmetry of roller of two sides is set with outer ring 2, is connected between two outer rings 2 by outer ring spacer 1；On the both ends circumference of outer ring spacer 1
It is corresponding on the end face circumference for the outer ring 2 that outer ring spacer 1 is connected to offer an at least Duan Yuan equipped at least one section of arc-shaped convex
Arc groove, the arc-shaped convex of outer ring spacer 1 and the circular groove quantity of outer ring 2 are equal, offer on the circumference of outer ring spacer 1
Oilhole.
Two outer rings 2 are connected by outer ring spacer 1, the outer diameter of outer ring spacer 1 is contacted with shell generates frictional resistance, reaches
To the purpose for preventing outer ring 2 from rotating.
More than, it is merely preferred embodiments of the present invention, but scope of protection of the present invention is not limited thereto, it is any
Those familiar with the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its invents
Design is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
