Abstract
The utility model relates to an oil storage structure of a bearing consisting of an axle center and a shaft housing only. The bearing can be made of plastic or metal or ceramics. The fit clearance between the axle center and the inner hole of shaft housing can range from 0 to 30 um according to requirements. The design of the shaft housing is as follows: the middle part of the shaft housing is provided with one or a plurality of through holes radically; the inner side, the outer side and the two end surfaces of the shaft housing are provided with one or a plurality of surface grooves. All the through holes are intercrossed and matched with the surface grooves, which has the function of storing oil and ensuring the recirculation of oil and ensures that the axle center is protected by the lubrication of oilchannel all the time, thereby eliminating noise, reducing temperature and enhancing the abrasive resistance. Moreover, the through holes intercrossed and matched with the surface grooves ensure that the particles falling off from the bearing rotating at a high speed for long time by abrasion and dust particles from the outside world occasionally falling into the bearing have a place to stay, thereby reducing the rate of scrap of the clamped axle center rotating at a high speed and the shaft housing caused by the intervention of such particles. Therefore, the service life of bearing is prolonged.
Description
[technical field]
The utility model relates to the oil-bearing structure of one type bearing, and this class bearing is made of axle core and axle sleeve.
[background technique]
At present, known this class bearing, the own no oil-bearing structure that has, the then oil-bearing structure that has is single, imperfection, thereby, the noise, heating of bearing, not wear-resisting and axle core common problem such as frequent stuck damage when the axle sleeve high speed is rotated in use can not well be solved.
[summary of the invention]
The purpose of this utility model is that class bearing provides a cover crisscross perfect oil-bearing structure for this reason, so that it in use reduces noise and temperature rise to greatest extent, increases wear resistance and reduces stuck damage fault, improves its working life.
The purpose of this utility model is achieved in that radially offers one and a plurality of open-works at the middle part of axle sleeve; Inboard, the outside and both ends of the surface at axle sleeve are offered one or more surface grooves.
Aforesaid bearing is characterized in that it is made of axle core and axle sleeve, and the length of axle core is greater than axle sleeve.During use, the axle core passes the axle sleeve center, and the matching gap of axle core and axle sleeve endoporus as required can be between 0～30 μ m.
Aforesaid bearing can be that in the following material any made:
A. plastics; B. metal: stainless steel or iron or copper or copper iron; C. ceramic: zirconium oxide or aluminium oxide or ZTA (toughness reinforcing) or titanium oxide.
Aforesaid bearing, one or more open-works that its axle sleeve middle part is radially offered can be not penetration hole or through hole, the shape in hole can be square, round, taper, fan-shaped or other polymorphic structure.
Aforesaid bearing, its surface grooves that is opened in inside and outside side of axle sleeve and both ends of the surface can be any in the following structural type: 1. surface grooves is opened in inside and outside side of axle sleeve and upper/lower terminal face, is interconnected; 2. surface grooves only is opened in the outer side surface and the upper/lower terminal face of axle sleeve; 3. surface grooves only axially is opened in the endoporus side of axle sleeve.
[advantage that invention has and effect]
The utility model is the following advantage of tool compared with prior art:
1. the through hole structure that radially is provided with in the middle part of the axle sleeve reduces a core and axle sleeve area of contact, thereby the friction between the two is reduced, and the noise of generation reduces.
2. because axle sleeve has been set up oil storage with open-work and surface grooves, make to store more lubricating oil and be able to long preservation in the bearing.Under the drive of bearing high speed rotating, lubricant oil constantly back and forth flows between oil storage open-work and surface grooves, make lubricant oil be dispersed throughout bearing everywhere, the heat that produces in also bearing being rotated simultaneously has been dispersed in bearing everywhere, reduce noise, temperature rise, friction effectively, prolonged the working life of bearing.
3. because axle sleeve has been set up oil storage open-work and surface grooves, the institute that the dust particle that makes bearing fall into bearing once in a while because of the particulate that splits away off from wearing and tearing and the external world in long-term high speed rotating has had sufficient Tibetan to receive, reduce intervention because of these particulates significantly and caused axle core and the stuck probability of scrapping of axle sleeve in the high speed rotating, thereby, prolonged working life of bearing.

In the accompanying drawing: 1. a core, 2. axle sleeve, 3. endoporus, 4. open-work,
5. surface grooves,
[embodiment]
As shown in Figure 1, a kind of bearing, it comprises a core 1 and axle sleeve 2, this core 1 adapts to the arbitrary axle sleeve 2 among Fig. 2～Fig. 4 embodiment.
In embodiment illustrated in fig. 2, radially offer one at the middle part of axle sleeve 2 and run through open-work 4, offered surface grooves 5 at the inside and outside side and the upper/lower terminal face of axle sleeve 2.
In the embodiment shown in fig. 3, radially offered one at the middle part of axle sleeve 2 and run through open-work 4,5 of surface grooves only are opened in the outer side surface and the upper/lower terminal face of axle sleeve 2.
In the embodiment shown in fig. 4, radially offered one at the middle part of axle sleeve 2 and run through open-work 4,5 of surface grooves only axially are opened in the surface of the endoporus 4 of axle sleeve 2;
In Fig. 2～Fig. 4 embodiment, what be provided with in the axle sleeve 2 runs through open-work 4 and 5 staggered cooperations of surface grooves, has formed the complete lubricant oil oil storage system of bearing.
