Abstract
A kind of thrust-bearing without outer ring, comprise retainer (1) and steel ball (2), retainer (1) is made up of annular lamellar body (10) and flanging (12), flanging (12) is molded in the interior outer side of lamellar body (10), on lamellar body (10), form several circular holes (11), in circular hole (11), be mounted with steel ball (2), the upper end of the inside and outside side edgefold of lamellar body (10) leans against on the sphere of steel ball (2).The steel ball of its bearing that adopts is held on retainer by the flanging clamp on retainer, and without steel ball clinching is embedded in retainer, thereby has reduced the installation difficulty of steel ball, has improved manufacturing efficiency.
Description
Technical field:
The utility model relates to the technical field of bearing, more specifically to a kind of thrust-bearing without outer ring.
Background technique:
Thrust-bearing is the special bearing for bearing specially axial force, is exactly the bearing of the power of the parallel direction of axle, and it is also thrust bearing, and it is generally by being made up of two thrust washers or more thrust washers and some rolling elements.And the bearing thrust pad being made up of thrust washer and rolling element and rolling element can depart from, the steel ball body in it easily drops, thereby causes the inefficacy of bearing.Also exist in the market some to only have the thrust-bearing of retainer and steel ball simultaneously, its steel ball is embedded in retainer, and its retainer material is generally plastic material, facilitates steel ball to embed and can flexible rotating, but its bearing intensity is not high, when bearing radial force is larger, easily cause cuing open of bearing to split.And retainer material is while adopting the metal material of yield strength, although bearing intensity is higher, it is inconvenient that its steel ball embeds in retainer, and manufacturing efficiency is low, and a lot of steel ball embeds in retainer and can not rotate, and scrappage is higher.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of thrust-bearing without outer ring is provided, and it is simple in structure, and intensity is high, saves material, and it is easily manufactured simultaneously, and manufacturing efficiency is high.
Technology solution of the present utility model is as follows:
Without a thrust-bearing for outer ring, comprise retainer and steel ball, retainer is made up of annular lamellar body and flanging, flanging is molded in the interior outer side of lamellar body, on lamellar body, form several circular holes, be mounted with steel ball in circular hole, the upper end of sheet inside and outside side edgefold leans against on the sphere of steel ball.
Described circular hole annular is evenly respectively on lamellar body, and the diameter of circular hole is less than the diameter of steel ball.
Described retainer adopts stainless steel, and the thickness of retainer is less than the diameter of steel ball.
Described circular hole is the nest hole of running through retainer lamellar body, and the surface in nest hole is sphere, and the diameter on surface, place, nest hole equals the diameter of steel ball.
The beneficial effects of the utility model are:
1, the steel ball of its bearing that adopts is held on retainer by the flanging clamp on retainer, and without steel ball clinching is embedded in retainer, thereby has reduced the installation difficulty of steel ball, has improved manufacturing efficiency.
2, the retainer that its adopts is stainless steel, thus the intensity that bearing is had increase.
3, it is simple in structure, does not need the thrust washer of bearing, thereby has saved material, has reduced cost of production.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the angle structural representation that changes of the present utility model;
Fig. 3 is sectional structure schematic diagram of the present utility model;
Fig. 4 is the structural representation of the utility model retainer.
In figure: 1, retainer; 2, steel ball; 10, lamellar body; 11, circular hole; 12, flanging.
Embodiment:
Embodiment: see shown in Fig. 1 to 4, a kind of thrust-bearing without outer ring, comprise retainer 1 and steel ball 2, retainer 1 is made up of annular lamellar body 10 and flanging 12, flanging 12 is molded in the interior outer side of lamellar body 10, on lamellar body 10, form several circular holes 11, be mounted with steel ball 2 in circular hole 11, the upper end of lamellar body 10 inside and outside side edgefolds 12 leans against on the sphere of steel ball 2.
Described circular hole 11 annulars are evenly respectively on lamellar body 10, and the diameter of circular hole 11 is less than the diameter of steel ball 2.
Described retainer 1 adopts stainless steel, and the thickness of retainer 1 is less than the diameter of steel ball 2, and the thickness of retainer 1 lamellar body 10 and the height sum of flanging 11 are less than the diameter of steel ball 2.
Described circular hole 11 is for running through the nest hole of retainer 1 lamellar body 10, and the surface in nest hole is sphere, and the diameter on surface, place, nest hole equals the diameter of steel ball 2.
Working principle: the utility model processing method is: first go out to have Internal and external cycle all to form the retainer 1 of flanging 12 by impact briquetting, and machine shaping goes out circular hole 11 on the lamellar body 10 of retainer 1, then steel ball 2 is placed in the circular hole 11 of lamellar body 10, withholding flanging 12 leans against on the sphere of steel ball 2 flanging 12 again, thereby steel ball 2 is clamped in retainer 1, and ensures a certain amount of play.Thereby compare Embedded bearing, the installation difficulty of steel ball reduces greatly, and indirectly its manufacturing efficiency is improved.
