Abstract
The present invention relates to a kind of Double-conical-surface roller bearing, it is arranged in including outer ring, inner ring, retainer and equably by retainer rolling element between inner ring and outer ring, described rolling element includes two of integrative-structure with the revolving body with conical surface of shaft, described outer ring has the tapered outer raceways matched with the same conical surface of shaft, inner ring has raceway in the taper matched with the same conical surface of shaft, and each same conical surface of shaft of rolling element forms line formed contact areas with raceway in tapered outer raceways, taper respectively.Two same conical surface of shaft that the present invention passes through rolling element, respectively with four line formed contact areas of raceway formation in the taper of the tapered outer raceways and inner ring of outer ring, drastically increase the bearing capacity of bearing, bigger combined load can be born, the spaces compacts such as robot (mechanical arm) joint and the complicated occasion of load is particularly suitable for use in.
Description
Technical field
It is especially a kind of that the bipyramid of larger combined load can be carried in smaller space the present invention relates to technical field of bearings
Face roller bearing.
Background technology
Bearing can be used for the load for bearing diversified forms, and the principal mode of load has radial load, axial force and moment of flexure (to incline
Cover torque).The bearing of different structure is different for the bearing capacity of this three kinds of loads typicals, the radial direction carrying of such as deep groove ball bearing
Power is larger, and axially the bearing capacity with moment of flexure is smaller；Thrust bearing can then carry larger axial load, but its radial direction carrying energy
Power is relatively low；Four spot contact bearings and crossed roller bearing can bear axial force, radial load and the simultaneous compound load of moment of flexure
Lotus, but four spot contact bearings are that, using steel ball as rolling element, rolling element is that point is contacted with inner and outer ring, and bearing capacity and rigidity have
Limit；And crossed roller bearing is then using cylindrical roller as rolling element, rolling element is linear contact lay with inner and outer ring, it is possible to achieve larger
Bearing capacity and rigidity, but be due to roller arranged crosswise, the rolling for there was only half quantity when bearing axial direction and tilting moment
Body is carried, and has the situation of roller " end contact ", therefore its bearing capacity is limited and and is not up to what whole rollers were carried
Ideal situation.
The content of the invention
The technical problem to be solved in the present invention is：In order to overcome deficiency in the prior art, the present invention provides a kind of bipyramid
Face roller bearing, its single bearing can carry larger combined load in less space, be particularly suitable for use in machinery man-machine
The complicated occasion of tool arm etc spaces compact and load is used,
The technical solution adopted for the present invention to solve the technical problems is：A kind of Double-conical-surface roller bearing, including it is outer ring, interior
Circle, retainer and rolling element between inner ring and outer ring is equably arranged in by retainer, described rolling element includes one
Two of structure have the revolving body with conical surface of shaft, and described outer ring has the tapered outer raceways matched with the same conical surface of shaft,
Inner ring has a raceway in the taper matched with the same conical surface of shaft, each same conical surface of shaft of rolling element respectively with tapered outer raceways,
Raceway formation line formed contact areas in taper.
Further, described same conical surface of shaft can have identical coning angle, it is possible to have different coning angles.
There is two fillet surfaces with conical surface of shaft of connection in the middle of described rolling element, it is round and smooth between same conical surface of shaft to ensure
Transition, prevents same conical surface of shaft joint from influenceing rolling element normally to roll with bearing internal external raceway contact.
Described outer ring is split type, and inner ring is monoblock type；Inner ring that can also be described is split type, and outer ring is overall
Formula.
The beneficial effects of the invention are as follows：The present invention by two same conical surface of shaft of rolling element, respectively with outside the taper of outer ring
Four line formed contact areas of raceway formation in the taper of raceway and inner ring, when bearing size is identical, relative to four spot contact bearings
With higher bearing capacity；And relative to crossed roller bearing, when bearing moment of flexure, due to owning for Double-conical-surface roller bearing
Rolling element can bear load, thus also just have higher bearing capacity and rigidity, can bear bigger combined load, this
The roller bearing using Double-conical-surface rolling element is planted, the spaces compacts such as robot (mechanical arm) joint is particularly suitable for use in and load is complicated
Occasion.

Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of Double-conical-surface roller bearing as shown in Figure 1, including outer ring 1, inner ring 2, retainer 3 and by retainer 3
Equably it is arranged in rolling element 4 between inner ring 2 and outer ring 1.
Described rolling element 4 includes two of integrative-structure with the revolving body with conical surface of shaft 4-1, as shown in Fig. 2 described
Same conical surface of shaft 4-1 there is identical coning angle；Can also be as shown in figure 3, described same conical surface of shaft 4-1 be designed to different circles
Cone angle.There is two fillet surfaces 5 with conical surface of shaft 4-1 of connection, the fillet surface 5 can be selected in the middle of described rolling element 4
The contour shapes such as circular arc, straight line, non-garden curve.
Described outer ring 1 has a tapered outer raceways 1-1 matched with the same conical surface of shaft 4-1, inner ring 2 have with it is described same
Raceway 2-1 in the taper that conical surface of shaft 4-1 matches, each same conical surface of shaft 4-1 of rolling element 4 respectively with tapered outer raceways 1-1, taper
Interior raceway 2-1 formation line formed contact areas, thus each rolling element 4 can simultaneously with raceway 2-1 in tapered outer raceways 1-1, taper
Form four line formed contact areas.
It is split type that outer ring 1, which is shown, in Fig. 4, and inner ring 2 is the bearing arrangement schematic diagram of monoblock type.
It is split type that inner ring 2, which is shown, in Fig. 5, and outer ring 1 is the bearing arrangement schematic diagram of monoblock type.
During work, outer ring 1 is relatively rotated with inner ring 2, and load passes through raceway 2-1 and rolling in tapered outer raceways 1-1, taper
Body 4 is transmitted between outer ring 1 and inner ring 2.Double-conical-surface roller bearing of the present invention, due to four line formed contact areas,
Therefore when bearing size is identical, there is higher bearing capacity relative to four spot contact bearings；And relative to crossed roller axle
Hold, when bearing moment of flexure, because all rolling elements 4 of Double-conical-surface roller bearing can bear load, thus also just have higher
Bearing capacity and rigidity, can bear bigger combined load, the roller bearing of this use Double-conical-surface rolling element 4, especially
Suitable for the spaces compacts such as robot (mechanical arm) joint and the complicated occasion of load.
Using the above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
