Abstract

The utility model relates to a novel press wheel bearing which comprises an outer ring, wherein brackets are arranged at two ends in the outer ring and are matched with bearing balls; the bearing balls are positioned in an annular groove in a core shaft; and steps are arranged at the inner circles at two ends of the outer ring. The novel press wheel bearing is simple in structure and good in oil leakage resistance; and external impurities are effectively prevented from entering the bearing. Thus, the bearing is long in service life.

Description

Novel pressure wheel bearing

Technical field

The utility model relates to technical field of bearings, especially a kind of for the pinch roller bearing on rotor spinning machine.

Background technique

For the pinch roller bearing on rotor spinning machine, mainly by outer ring, mandrel, retainer, rolling element (roller or ball), dust ring etc., formed; Kind of bearings in use at present, the grease proofing poor effect at two ends, outer ring, bearing is being pressed after supporting wheel sheet, bearing is when running up, and two ends, outer ring there will be oil leakage phenomenon, also easily enters impurity in bearing simultaneously, cause bearing to wear and tear rapidly, it is large that precise decreasing, noise become, and rotate the unstable surface that causes and produce overheated and burn inefficacy, reduces working life.

Model utility content

The applicant, for above-mentioned shortcoming of the prior art, provides a kind of Novel pressure wheel bearing, and it is simple in structure, and oil-leakage-prevention works very well can effectively prevent that introduced contaminants from entering bearing inside, bearing long service life.

The technological scheme that the utility model adopts is as follows:

Novel pressure wheel bearing, comprises outer ring, and the two ends, inside of outer ring are with support, and support matches with ball, and ball is positioned at the circular groove on mandrel; Be positioned at two ends, outer ring inner circle with step;

Further technological scheme is as follows:

Preferably, dust ring all with draw-in groove, is equipped with in described draw-in groove near support place in the inner circle two ends of outer ring;

Preferably, in step, diameter of a circle is: Φ 10～Φ 24mm, width is: 0.5～10mm.

The beneficial effects of the utility model are: the two ends at bearing outer ring arrange respectively step, when bearing is pressed to supporting wheel sheet, the step at two ends, outer ring coordinates formation maze-type structure with the circular groove on supporting wheel sheet, in the outer ring inner circle near support place, draw-in groove is set simultaneously, dust ring is installed in draw-in groove, can effectively prevent in bearing that lubricant oil is to external leakage, also can prevent that introduced contaminants from entering bearing inside, the unfavorable wearing and tearing of minimizing to bearing, extend the working life of bearing, reduced the cost of production of enterprise.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the mated condition schematic diagram that the utility model presses supporting wheel sheet.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

As shown in Figure 1, the utility model comprises outer ring 1, and the two ends, inside of outer ring 1 are with support 2, and support 2 matches with ball 3, and ball 3 is positioned at the circular groove on mandrel 6; 1 inner circle two ends, outer ring all with draw-in groove, are equipped with dust ring 4 near support 2 places in described draw-in groove, be positioned at outer ring 1 two ends inner circle with step 5, according to actual technical requirements, preferably, in step, diameter of a circle is: Φ 10～Φ 24mm, and width is: 0.5～10mm; As shown in Figure 2, bearing is being pressed to circular groove 8 on supporting wheel sheet 7 when interior, circular groove 8 coordinates formation maze-type structure with step 5, so can effectively prevent that the lubricant oil in bearing from leaking to the external world when bearing runs up, also can prevent that 1 two ends enter bearing inside to extraneous impurity from outer ring, the labyrinth structure forming is combined with dust ring 4, make the grease proofing dust-proof effect of bearing better, guaranteed the usability of bearing, extend its working life, reduced enterprise's cost of production.

More than describing is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
