The high-rotating-speed thrust cylindrical roller bearing disclosed by the utility model has the characteristics of good lubricating effect, good rotating stability, high limit rotating speed and long service life; the limit rotating speed of the thrust cylindrical roller bearing with the rolling body being a steel cylindrical roller can be increased by 1.5-2 times; the limit rotating speed of the thrust cylindrical roller bearing with the rolling body being a ceramic cylindrical roller made of silicon nitride ceramics can be increased by 2-2.5 times.
Description
Technical field
The utility model relates to a kind of rolling bearing, relates in particular to a kind of high rotating speed cylindrical roller thrust bearing.
Background technique
Cylindrical roller thrust bearing is often combined into high rigidity bearing configuration, can bear without difficulty heavy load and oscillating load; This bearing can bear the thrust load that one direction is very large, but can not bear radial load, and they do not have self-aligning ability; Due to traditional cylindrical roller thrust bearing, during high speed, because rolling element centrifugal force is large, the outer rib frictional heating of rolling element end face and retainer fenestra is serious, and the life-span is low; Because fenestra and rolling element have certain gap, cause retainer to rotate when work unstable, produce vibrations and with the random friction of rolling element, limited the limit speed of cylindrical roller thrust bearing.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of high rotating speed cylindrical roller thrust bearing, has high lubricating effect, and rotational stabilization is good, and limit speed is high, the characteristic of long working life.
For achieving the above object, the utility model is to adopt following technological scheme:
A kind of high rotating speed cylindrical roller thrust bearing, by the rolling element between blowout patche and seat ring and retainer assembling, formed, described seat ring is provided with the seat ring rib of oil duct, described seat ring is also provided with seat ring guide surface simultaneously, this guide surface is inclined-plane, on this guide surface, have oil film wedge simultaneously, at seat ring guide surface, be arranged with seat ring oil film wedge.
Described a kind of high rotating speed cylindrical roller thrust bearing, described retainer is provided with retainer guide surface, and this guide surface is inclined-plane.
Described a kind of high rotating speed cylindrical roller thrust bearing, the end face of described rolling element is sphere.
Described a kind of high rotating speed cylindrical roller thrust bearing, described bearing blowout patche and seat ring adopt bearing metal manufacture.
Described a kind of high rotating speed cylindrical roller thrust bearing, the ceramic cylinder roller that described rolling element adopts metal cylindrical roller or silicon nitride ceramics to make.
Described a kind of high rotating speed cylindrical roller thrust bearing, described retainer adopts copper production.
Owing to having adopted technique scheme, the utlity model has following superiority:
High rotating speed cylindrical roller thrust bearing has a high lubricating effect, and rotational stabilization is good, and limit speed is high, the characteristic of long working life; Rolling element is that the limit speed of the cylindrical roller thrust bearing of steel cylindrical roller can improve 1.5-2 doubly; The limit speed that rolling element is the cylindrical roller thrust bearing of the ceramic cylinder roller with silicon nitride ceramics making can improve 2-2.5 doubly.

Fig. 2 is the structural representation of seat ring;
Fig. 3 is the structural representation of retainer.
In figure: 1, seat ring; 1.1, seat ring rib; 1.2, seat ring guide surface; 1.3, seat ring oil film wedge; 2, retainer; 2.1, retainer guide surface; 3, rolling element; 4, blowout patche.
Embodiment
A kind of high rotating speed cylindrical roller thrust bearing, by the rolling element (3) between blowout patche (4) and seat ring (2) and retainer (2) assembling, formed, described seat ring (1) is provided with the seat ring rib (1.1) of oil duct, its effect has two aspects, the one, kind of lubricant storage, improves the lubricated of rolling element (3) and raceway; The 2nd, during high speed, prevent because of retainer (2) destroy after rolling element (3) raceway that flies out have an accident.Described seat ring is also provided with seat ring guide surface (1.2) simultaneously, and this guide surface is inclined-plane, has oil film wedge (1.3) on this guide surface simultaneously; Retainer (2) is provided with retainer guide surface (2.1), and this guide surface is inclined-plane; When retainer guide surface (2.1) rotates along seat ring guide surface (1.2), easily form lubricant film, on seat ring guide surface (1.2), have oil film wedge (1.3) simultaneously, be convenient to oil storage and form dynamic pressure oil film, reduce the generation of frictional heat, improved the rotating speed of bearing; Described retainer guide surface (2.1) rotates along seat ring guide surface (1.2), because guide surface is inclined-plane, limited retainer (2) skew axially and radially, guaranteed axially locating precision and the radial rotary precision of retainer (2) when work, and then guaranteed that retainer is along bearing centre line stabilization rotation, while having avoided work, because retainer rotation is unstable, cause the random friction with rolling element; Rolling element (3) end face is sphere, when bearing operation, the outer rib of retainer fenestra for point contacts, has reduced area of contact with rolling element, improved greasy property, greatly limit has reduced rolling element (3) end face and the outer fricative heat of rib of retainer (2) fenestra; Bearing blowout patche (4) and seat ring (1) adopt the manufacture of high-quality Bearing Steel; Rolling element (3) adopts the cylindrical roller of steel, or the ceramic cylinder roller that adopts silicon nitride ceramics to make; Described retainer (2) adopts mechanical property and the good brass manufacture of self-lubricating property; The utlity model has high lubricating effect, rotational stabilization is good, and limit speed is high, the characteristic of long working life.Compare with same model, the limit speed of the cylindrical roller thrust bearing that rolling element (3) is steel cylindrical roller can improve 1.5-2 doubly.The limit speed that rolling element (3) is the cylindrical roller thrust bearing of the ceramic cylinder roller with silicon nitride ceramics making can improve 2-2.5 doubly; When bearing working, blowout patche (4) drives rolling element (3) and retainer (2) assembly to rotate along bearing centre line stabilization.
