Abstract
The present invention discloses a kind of roll cone roller bearing, including bearing outer ring, cone, some big taper rollers and conicle roller, between bearing internal external circle, set solid arranges that big taper roller and conicle roller, big taper roller and conicle roller interval are laid, the pure rolling taper roll bearing of the present invention, roller realizes pure rolling with bearing channel, bear linear velocity high, bearing capacity is big, and noise is little, reliability is high, life-span length.
Description
Technical field
The present invention relates to a kind of roll cone roller bearing, particularly pure rolling taper roll bearing.
Background technology
The taper roll bearing for either still expiring ball with retainer cannot solve asking for roller and raceway groove sliding friction
Topic, the taper roll bearing with retainer cause the sliding friction of roller and raceway groove due to the friction between roller and retainer,
And full roller cone roller bearing is due to two neighboring roller stand under load simultaneously during work, when the two roller contacts, roller with
The frictional resistance of raceway groove is increased dramatically, and sliding friction occurs, and particularly in high-speed overload, roller and bearing channel easily wear and tear burning
Wound, service life are short, it is impossible to meet high demand.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of pure rolling taper roll bearing, roller and bearing channel
Pure rolling is realized, linear velocity is high, and bearing capacity is big, and noise is little, and reliability is high, life-span length.
To reach above-mentioned purpose, the present invention is achieved by the following technical solutions：
A kind of roll cone roller bearing, which includes the rolling of bearing outer ring, cone, some big taper rollers and conicle
Son, between bearing internal external circle, set solid arranges big taper roller and conicle roller, big taper roller and conicle roller interval cloth
If the large and small roller is without retainer.
Further, the big taper roller with the taper of conicle roller as length, the stub end of conicle roller
Stub end diameter d1s of the diameter d2 less than big taper roller, the wherein value of d1-d2 are 0.01～0.1mm.
Further, the gap s=0.01～0.15mm of the adjacent big taper roller and conicle roller.
The full sub- taper roll bearing of the present invention, roller realize pure rolling with bearing channel, and coefficient of friction is little, the line for bearing
Speed is high, and bearing capacity is big, and noise is little, and reliability is high.
The application of pure rolling taper roll bearing of the present invention not only promotes metallurgy, electric power, building machinery, construction material, energy
The development of the industries such as source, moreover it is possible to meet the high-end fields such as automobile, wind-powered electricity generation, high-grade lathe, high ferro, Aero-Space and national defense and military
Using.
Description of the drawings
Fig. 1 is one front schematic view of the embodiment of the present invention
Fig. 2 is embodiment of the present invention one side schematic diagram
Fig. 3 is one taper roller schematic diagram of the embodiment of the present invention
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings：
Embodiment：Such as Fig. 1-3, a kind of pure rolling taper roll bearing, including bearing outer ring 1, cone 2, Ruo Gan great
Taper roller 3 and conicle roller 4, between bearing outer ring 1 and cone 2, set solid arranges big taper roller 3 and conicle rolling
Son 4, big taper roller 3 and the interval of conicle roller 4 are laid, and big taper roller 3 and conicle roller 4 are without retainer.
As Fig. 1, big taper roller 3 are consistent with length with the taper of conicle roller 4, the stub end of big taper roller 3 is straight
The diameter difference of the stub end diameter d2 of footpath d1 and conicle roller 4 be d1-d2 value be 0.01～0.1mm, the value scope of d1-d2
Much larger than the foozle value of roller, it is through scientific design.The value of d1-d2 is too little, and adjacent two roller is while stand under load, roller
It is increased dramatically with the frictional resistance of raceway groove, the sliding friction for easily locking occur and producing；The value of d1-d2 is too big, conicle rolling
Sub 4 gaps are too big, play easily occur, and noise is big, or even affects normal work.
Such as Fig. 1, size taper roller by small one and large one interval laying be lay between two neighboring big taper roller 3 it is little
Taper roller 4.During work, each roller had not only revolved round the sun but also rotation, and due to the presence of diameter difference, big taper roller 3 is primarily subjected to load,
As interval is laid, the sense of rotation of big taper roller 3 is consistent, now the pure friction rolling of 3 stand under load of big taper roller, coefficient of friction
Little, although conicle roller 4 can be with the reverse rotation of 3 CONTACT WITH FRICTION of big taper roller, due to not stand under load, coefficient of friction is little, several
Frictional resistance is not produced.Therefore, solve when original full roller cone roller bearing works due to while stand under load causes roller
The sliding friction problem for being increased dramatically and occurring with the frictional resistance of raceway groove.
As the gap s=0.01～0.15mm of Fig. 1, big taper roller 3 and conicle roller 4, gap are too little, roller is easy
It is stuck, burn of being worn and torn during high-speed overload at once；Gap is too big, and play easily occurs in roller, and noise is big, affects normal work.
The present invention solves the problems, such as that roller and raceway groove cannot realize pure rolling friction, by with NSK same model bearings
Contrast test, i.e., with same moment of torsion swivel bearing, test bearing rotational time：Present invention rotation stopped after 4.13 seconds, and NSK
Rotation stopped after 2.01 seconds, and its frictional resistance is substantially reduced, and under the operating mode of high-speed overload, effect is more significantly.
The present invention is applicable not only to single-row tapered roller bearing, is also suitable, not only promotes on many row tapered roller bearings
The development of the industries such as metallurgy, electric power, building machinery, construction material, the energy, moreover it is possible to meet automobile, wind-powered electricity generation, high-grade lathe, high ferro,
The application of the high-end field such as Aero-Space and national defense and military.
Described above, only using the embodiment of this origination techniques content, any those skilled in the art use this wound
Make done modification, change, all belong to the interest field of this creation opinion, and be not limited to those disclosed embodiments.
