Description
Technical field
It the utility model is related to field of bearings, more particularly to a kind of special-shaped needle bearing.
Background technology
Bearing is a kind of important parts in contemporary plant equipment, and its major function is the mechanical rotary body of support, is dropped
Coefficient of friction in low mechanical rotary body motion process, and ensure its rotating accuracy.
By the difference of motor element frictional property, bearing can be divided into rolling bearing and the major class of sliding bearing two, wherein rolling
Bearing is normalized, seriation, but its radial dimension, vibration and noise are larger compared with sliding bearing, and price is also higher.
Needle bearing is a kind of conventional bearing, but the needle roller of common needle bearing is usually cylinder, it is difficult to is undertaken
The active force of axial direction, needle roller is axially poor from restraining ability, and restricted application is, it is necessary to improve.
Utility model content
The purpose of this utility model is to provide a kind of special-shaped needle bearing, the resistance energy of lifting bearing axial force
Power, strengthen needle roller axially from restraining ability.
To use following technical scheme up to this purpose, the utility model：
A kind of special-shaped needle bearing, including：Bearing case and several needle rollers, several needle roller difference annular arrays are set
On the inwall of bearing case, evagination is provided with a circle and needle roller into cydariform, the inwall of the bearing case in the middle part of the needle roller
Corresponding first arc groove, is symmetrically arranged with the first inner sleeve and the second inner sleeve in the bearing case, first inner sleeve and
The outer wall of second inner sleeve is provided with the second arc groove corresponding with needle roller, is provided with the bearing case positioned at the first inner sleeve
First Spring Card of end, the second spring card positioned at the second inner sleeve end is provided with the bearing case.
Wherein, the outer wall of the bearing case is provided with the oil filler point connected with the first arc groove.
Wherein, bearing pin is provided between first inner sleeve and the second inner sleeve and carries out spacing connection.
Wherein, the endoporus of first inner sleeve and the second inner sleeve is respectively diameter identical straight hole.
Wherein, mounting groove corresponding with the first Spring Card and second spring card is provided with the bearing case inwall.
The beneficial effects of the utility model：A kind of special-shaped needle bearing, especially employ the needle roller of cydariform, middle outer umbo
Structure can effectively carry out axial limiting, avoid needle roller from moving axially when with the first arc groove and the cooperation of the second arc groove, then
Plus the spacing of the first Spring Card and second spring card, greatly improve the first inner sleeve and the second inner sleeve is held to axial force
It is more stable by ability, use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.

Oilhole 6 facilitates the injection of lubricating oil, strengthens the lubrication of needle roller 2, reduces friction and the vibration problems rotated.
Bearing pin 7, which is provided with, in the present embodiment, between the inner sleeve 4 of the first inner sleeve 3 and second carries out spacing connection so that the
One inner sleeve 3 and the second inner sleeve 4 hold together, and structure is more stable, and install and unpick and wash more convenient.
In the present embodiment, the endoporus of the inner sleeve 4 of the first inner sleeve 3 and second is respectively diameter identical straight hole, convenient to turn
The insertion of axle, assembling facility.
In the present embodiment, it is provided with the inwall of bearing case 1 corresponding with the first Spring Card 9 and second spring card 5
Mounting groove 8, mounting groove 8 facilitate the installation of the first Spring Card 9 and second spring card 5 and spacing, strengthened to the first inner sleeve 3 and
Two inner sleeves 4 it is spacing, lift the resistivity of axial force, lift the stability used.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications
To limitation of the present utility model.
