Abstract
The utility model discloses a kind of rotation high-precision formula needle bearings, including inner ring and needle roller, the at least two groups roller mounting groove that the appearance of the inner ring is arranged integrally formed with array, and needle roller is installed in roller mounting groove, the two sides of the roller mounting groove are respectively arranged with spherical groove, and the both ends of needle roller are equipped with the second outer ring integrally formed with the outside socket with the matched hemispherical projections of spherical groove, the roller, and are spirally connected on the outside of the second outer ring and are equipped with the first outer ring.The needle roller of the bearing is limited in specific position and is rolled, and since the two sides of needle roller have spherical groove and protection edge to be limited, therefore the bearing can carry axial load, to further reduce swing situation of the needle roller under complex load, so that bearing operation is more steady, with higher transmission accuracy, there is very high practical value.
Description
Technical field
The utility model relates to bearing design technology field, specially a kind of rotation high-precision formula needle bearing.
Background technique
Bearing is mainly used for reducing the friction between shaft and bearing block, to effectively extend the service life of shaft.
Bearing can be divided into many types according to its form and function, and wherein needle bearing can be using elongated cylindrical roller
The thickness of bearing outer ring is effectively reduced under the premise of ensureing bearing capacity, thus reduction equipment size.But existing rolling
Needle bearing is difficult to carry axial force during use, and lacks necessary fixed structure, causes needle roller in rolling process
It is middle to there is mobile position swing, to cause the shake of shaft in transmission process, reduce transmission accuracy.If invention one
The novel needle bearing that kind can be carried certain axial load, and can effectively reduce needle roller swing is just able to solve such
Problem, we provide a kind of rotation high-precision formula needle bearings thus.
Utility model content
The purpose of this utility model is to provide a kind of rotation high-precision formula needle bearings, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions: a kind of rotation high-precision formula needle bearing, packet
Inner ring and needle roller, at least two groups roller mounting groove that the appearance of the inner ring is arranged integrally formed with array, and needle roller is included to install
In in roller mounting groove, the two sides of the roller mounting groove are respectively arranged with spherical groove, and the both ends of needle roller integrally formed with
Outside socket with the matched hemispherical projections of spherical groove, the roller is equipped with the second outer ring, and the outside spiral shell of the second outer ring
It connects and the first outer ring is installed, the outside of second outer ring and the first outer ring is integrally formed useful mobile in limitation needle roller upper end
Protection edge, and be provided on the outside of the first outer ring and the second outer ring hexagonal protrusion, the centre of first outer ring is provided with
Annular groove, and annular groove annular array is provided with the fuel feed hole through the first outer ring and the second outer ring.
Preferably, it is provided with oil guide groove on the outside of first outer ring and the second outer ring, and oil guide groove is connected with fuel feed hole.
Preferably, it is provided with corresponding location hole on first outer ring and the second outer ring, and positioning hole is provided with and determines
Position column.
Preferably, a limit hole easy to disassemble is provided at each angle of the hexagonal protrusion.
Compared with prior art, the utility model has the beneficial effects that the bearing using it is preceding by needle roller in sequence successively
It is placed in roller mounting groove, is then respectively carried out the first outer ring and the second outer ring by the two sides of inner ring to screw tight installation, and benefit
It is fixed with positioning column, needle roller is limited in specific position and is rolled at this time, and since there are spherical shape in the two sides of needle roller
Slot and protection edge are limited, therefore the bearing can carry axial load, are carried to further reduce needle roller in complexity
Swing situation under lotus has higher transmission accuracy so that bearing operation is more steady, has very high practical value.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the technical solution in the utility model, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of rotation high-precision formula needle bearing, including
Inner ring 1 and needle roller 12, at least two groups roller mounting groove 11 that the appearance of inner ring 1 is arranged integrally formed with array, and needle roller 12 are pacified
Loaded in roller mounting groove 11, the two sides of roller mounting groove 11 are respectively arranged with spherical groove 13, and the both ends of needle roller 12 are integrated
It forms and the second outer ring 5 is installed with the matched hemispherical projections of spherical groove 13, the outside socket of roller, and the second outer ring 5
Outside, which is spirally connected, is equipped with the first outer ring 2, and the outside of the second outer ring 5 and the first outer ring 2 is integrally formed useful in limitation needle roller 12
The mobile protection edge 10 in upper end, and the outside of the first outer ring 2 and the second outer ring 5 is provided with hexagonal protrusion 9, the first outer ring 2
Centre is provided with annular groove 3, and 3 annular array of annular groove is provided with the fuel feed hole 7 through the first outer ring 2 and the second outer ring 5.
Further, the outside of the first outer ring 2 and the second outer ring 5 is provided with oil guide groove 6, and oil guide groove 6 and 7 phase of fuel feed hole
