Abstract
The present invention relates to a kind of bearing, which is made of outer ring, inner ring, retainer, steel ball, spacer ring and bushing, and inner ring, outer ring are respectively two pieces, it is supported by retainer, spacer ring cross section is rectangle, and bearing oil is filled in the cavity of spacer ring, offers micropore on the outer wall of spacer ring.When bearing bidirectional axial force, two column rolling elements, one steel ball energy while stress, its ability for bearing axial load is very big, it is twice of four-point contact ball, also above double row angular contact bearing, can works under high-speed overload, and installation, convenient disassembly, long service life, it is very convenient to modifying rolling mill and application, it is a kind of ideal double ball thrust bearing of rolling mill roll.
Description
Technical field
The invention belongs to the milling train fields for rolling metal strip, are related to a kind of roll axis of rolling for rolling mill
It holds, especially a kind of bearing.
Background technique
At this stage, rolling-mill roller rolling bearing is supported instead of bakelite tile, there is the speed and precision of rolling very
It is big to improve, but there is also one very big problem after roll is using rolling bearing, it is exactly the thrust bearing not yet one of roll
A preferable structure type, such as: double-row angular contact bal bearing, the class bearing have two column rolling elements, and width is larger, is suitable in height
Work under the conditions of the medium axial load of speed, because its when bearing axial force can only a column stress, therefore energy of its receiving axial load
Power is small.For another example double row tapered roller bearing, such bearing axial load is larger, but there are many disadvantages in use, 1. pole
It is low to limit revolving speed, not can be adapted to high-speed rolling；2. roller large end face and centre rib are sliding frictions, when moment, axial force was very big,
Bearing is easily burnt；3. such bearing width size is very big, bearing housing much room is occupied, the volume of bearing housing is increased
Greatly；4. the class bearing had not only born radial force but also born axial force, since its inner ring cannot hold with roller diameter tight fit in rolling
Easily occur seizing, excessively heated axle phenomenon, this is the deficiency of existing thrust bearing for rolling mill.
Summary of the invention
It is to design a kind of bearing, to improve bearing it is an object of the invention to overcome the above-mentioned prior art
Revolving speed and axial carrying capacity, prolong the service life, and overcome the shortcomings of existing thrust bearing for rolling mill.
The present invention is achieved by the following technical solutions:
The present invention is made of outer ring, inner ring, retainer, steel ball, spacer ring, bushing.There is two pieces in outer ring, and beanstalk shape is circle
Shape.Inner ring has four, and shape is also ring shape.Outer ring inner wall, interior ring outer wall have steel ball curved track.Retainer has two pieces, protects
The shape of frame is held compared with retainer, retainer entangles steel ball, and steel ball is spherical, retainer, steel ball outer ring and inner ring it
Between.Spacer ring is one, and spacer ring is between four inner rings；The spacer ring is the plastic cement torus with cavity structure.Spacer ring is transversal
Face is ellipse, and bearing oil is filled in the cavity of spacer ring, offers micropore on the outer wall of spacer ring.
Bushing is one, and bushing is cylindrical shape, and bushing outer right wall has edge of table, and inner ring, spacer ring inner wall are on bushing, lining
Set inner wall, which is supplied on roll diameter of roller, to be installed.
Beneficial effects of the present invention:
For the present invention when bearing bidirectional axial force, two column rolling elements, one steel ball energy while stress bear axial load
Ability it is very big, be twice of four-point contact ball, also above double row angular contact bearing, can work under high-speed overload, and
Installation, convenient disassembly, it is a kind of ideal thrust bearing of the roll that long service life is very convenient to modifying rolling mill and application.
Detailed description of the invention
Fig. 1 is bearing plane figure of the present invention.
In figure, 1 it is outer ring, 2 is inner ring, 3 is retainer, 4 is steel ball, 5 is spacer ring, 6 is bushing.
Specific embodiment
Below according to attached drawing, 1 couple of present invention is described in detail
As shown in Figure 1, this bearing is made of outer ring 1, inner ring 2, retainer 3, steel ball 4, spacer ring 5 and bushing 6, outer ring 1 has
Two pieces, shape are ring shape.Inner ring 2 has four, and shape is also ring shape.1 inner wall of outer ring, 2 outer wall of inner ring have steel ball 4
Curved track.Retainer 3 has two pieces, and for the shape of retainer 3 compared with retainer, retainer 3 entangles steel ball 4.Steel ball 4 is spherical shape
Body, retainer 3, steel ball 4 are between outer ring l and inner ring 2.Spacer ring 5 is the annulus bodily form；Spacer ring 5 is one, and corner circle 5 is in four
Between circle 2；Also, in order to eliminate buffering and reduce vibration, the spacer ring 5 is designed as the plastic cement torus with cavity structure.
5 cross section of spacer ring is rectangle or ellipse (being rectangle in figure, ellipsoidal structure is not shown), is filled in the cavity of spacer ring 5
Bearing oil offers micropore on the outer wall of spacer ring 5.Bushing 6 is one, and bushing 6 is cylindrical shape, and 6 outer right wall of bushing has platform
Side, on bushing 6,6 inner wall of bushing, which is supplied on roll diameter of roller, to be installed for inner ring 2,5 inner wall of spacer ring.
