Description
Technical field
The present invention relates to automobile bearing field, more particularly to a kind of novel conical needle bearing.
Background technology
At present, the thrust stub bearing of automobile front suspension angle steering, bearing body front weight turn front-wheel
To structure is that roller is filled inside two lassos, and the roller of Bearing inner does not have angle, can only bear axial load, is carried
Lotus is only 1750Ib, and this structure causes the stress of Bearing inner to concentrate in the axial direction, influences the service life of bearing, existing
In technology, also there is the bearing using bevel-type roller, although this bevel-type bearing bearing capacity improves, service life is not yet
Long, conical roller is highly susceptible to squeeze and be displaced close to the position of bearing inner race, and when carrying work, loss is larger.
Invention content
The technical problem to be solved by the present invention is to：In order to overcome the deficiencies of the prior art and provide a kind of novel conical needle roller
Bearing.
The technical solution adopted by the present invention to solve the technical problems is：A kind of novel conical needle bearing, including seat ring,
Blowout patche, housing and several rollers, each roller are circumferentially uniformly arranged on seat ring centered on the center of circle of blowout patche, and each roller is respectively provided with
Between seat ring and blowout patche, the housing is set on the outside of blowout patche and seat ring, and the periphery of the blowout patche and seat ring is consolidated by housing
Fixed connection, the roller include limiting section and turning part, and the limiting section is cylinder, axis of the turning part along limiting section
The section in direction is isosceles trapezoid, the upper bottom in the section of the turning part and the bottom surface connection of limiting section and the section of turning part
Length is equal to the diameter of limiting section bottom surface, and two bevel edges in the section of the turning part are formed between the axis of limiting section
9.5 ° of angle.
Preferably, the seat ring, blowout patche, housing and roller are carburizing bearing Steel material.
In order to increase the service life of entire bearing, the firmness of roller is improved, the limiting section and turning part are integrated
Molding structure.
The invention has the advantages that the novel conical needle bearing can bear load axially and radially simultaneously, carrying
Ability reaches 6000Ib, reduces the pressure suffered by bearing inner race, improves the stability of total, extends bearing
Service life.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the novel conical needle bearing of the present invention；
In figure：1. seat ring, 2. blowout patches, 3. housings, 4. turning parts, 5. limiting sections.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows composition related to the present invention.
As shown in Figure 1, a kind of novel conical needle bearing, including seat ring 1, blowout patche 2, housing 3 and several rollers, each roller
It is circumferentially uniformly arranged on seat ring 1 centered on the center of circle of blowout patche 2, each roller is arranged between seat ring 1 and blowout patche 2, described
Housing 3 is set in 1 outside of blowout patche 2 and seat ring, and the blowout patche 2 is fixedly connected with the periphery of seat ring 1 by housing 3, the roller
Including limiting section 5 and turning part 4, the limiting section 5 be cylinder, section of the turning part 4 along the axis direction of limiting section 5
For isosceles trapezoid, the upper bottom in the section of the turning part 4 is connect with the bottom surface of limiting section 5 and the length in the section of turning part 4 etc.
Diameter in 5 bottom surface of limiting section, two bevel edges in the section of the turning part 4 form 9.5 ° between the axis of limiting section 5
Angle.
Preferably, the seat ring 1, blowout patche 2, housing 3 and roller are carburizing bearing Steel material.
In order to increase the service life of entire bearing, the firmness of roller is improved, the limiting section 5 and turning part 4 are one
Forming structure.
Compared with prior art, which can bear load axially and radially, bearing capacity simultaneously
Reach 6000Ib, reduce the pressure suffered by bearing inner race, improve the stability of total, extend the use of bearing
Service life.
Using 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 range is not limited to the content on specification, it is necessary to determine its technical scope according to right.
