Abstract

The utility model provides a Flyer bearing which comprises an inner ring, an outer ring, a rolling body and sealing rings, wherein the inner ring is arranged on a rotation shaft of the flyer and is fixed with the rotation shaft of the flyer, the outer ring is arranged on the inner ring, both ends of the outer surface of the inner ring are respectively provided with an annular groove, an annular groove is correspondingly arranged on the inner surface of the outer ring, and the rolling body is arranged in a chamber channel formed between the inner groove and the outer groove. The sealing rings are arranged at both ends of the inner ring and the outer ring, and the outer surface of the outer ring is provided with a groove for installing a baffle ring. The number of parts of the utility model is lower, so the structure is simple and compact. Moreover, the size of the rolling body is larger than the size of a steel ball adopted by the existing bearing, so the utility model has the characteristics of large bearing force and long service life. Meanwhile, the utility model adopts integral design, so the bearing can be directly installed and used by users after leaving the factory. The existing process of assembling the bearing on a sleeve and then installing is not needed. The whole bearing can be directly replaced during maintenance, which is rapid and convenient.

Description

Flyer bearing

Technical field

The utility model relates to Speed frames flier bearing in a kind of textile machine, and flier is a twisting winding shaping usefulness when supplying holder ingot or overhanging-spindle fly frame spinning rove, and this bearing provides the supporting of flier rotation.

Background technology

The flier installation diagram as shown in Figure 1 on the existing coarse sand machine, it has adopted two standard deep groove ball bearings 2 that are used to support flier rotating shaft 1, be installed in the both sides of bearing block 4, the centre has spacer 3 to cut apart, and bearing block 4 is fixed on the rail plate by self convex shoulder and nut.Standard universal bearing simple in structure, that select for use is purchased the advantage convenient, that maintenance cost is low though prior art has.But also there is following shortcoming:

1, the deep groove ball bearing of two standards of Cai Yonging have size, beat, the difference of index such as play, influenced the operating accuracy and the service life of flier.

2, two standard deep groove ball bearings complex process in installation process requires high.

3, in the seal structure complex at two of flier, the processing cost height.

4, owing to be the configuration that sleeve adds bearing, make the bearing of selecting for use be subjected to the restriction in space, the carrying of bearing is limited.

Summary of the invention

Goal of the invention: the purpose of this utility model is the deficiency that exists at prior art, and a kind of compact conformation, easy for installation, precision is high, the life-span is long flyer bearing are provided.

Technical scheme: flyer bearing described in the utility model comprises inner ring, outer ring, rolling element and sealing ring; Inner ring is enclosed within on the flier rotating shaft and is fixing with it, and the outer ring is enclosed within on the inner ring, respectively is provided with an annular groove at the two ends of inner ring outer surface, is provided with annular groove accordingly at inner surface, and rolling element is installed in the cavity that forms between the inside and outside groove.

Sealing ring is equipped with at two ends at Internal and external cycle, guarantees that the interior lubricating grease of flyer bearing does not leak and the intrusion of external dust and flyings.

Outer surface in the outer ring has a groove, back-up ring can be installed use as the location of whole bearing.

Beneficial effect:, make simple and compact structure because the utility model reduced number of spare parts; And rolling element is bigger than the steel ball specification that existing bearing adopts, and bearing capacity is big, the long service life characteristics so the utlity model has; Simultaneously, the utility model integrated design makes the bearing back of dispatching from the factory just can directly install and use to user place, and unnecessaryly as existing will be assembled into the process that sleeve is installed again earlier, can directly change whole bearing when safeguarding, and is quick, conveniently.

Fig. 1 is existing flyer bearing structural representation;

Fig. 2 is a flyer bearing structural representation of the present utility model.

The specific embodiment

As shown in the figure, described flyer bearing, enclose within it on 5 the outer surface and have two annular grooves that the cross section is a circular arc, corresponding, on the inner hole surface of outer ring 6, also have two grooves of circular arc, two row's rolling elements 7 are installed between these two pairs of grooves, is the clearance control between groove and rolling element at very little number? within, guarantee that the circumference of whole flyer bearing is beated and axial runout.At the two ends of Internal and external cycle sealing ring 8 is housed, 6 outer surface also equally is provided with screw thread with prior art in the outer ring, by nut 9 flyer bearing is fixed on the gusset 10.

Claims (3)

1, a kind of flyer bearing is characterized in that: this bearing comprises inner ring (5), outer ring (6), rolling element (7) and sealing ring (8); Inner ring (5) is enclosed within on the flier rotating shaft and is fixing with it, outer ring (6) is enclosed within on the inner ring (5), two ends at inner ring (5) outer surface respectively are provided with an annular groove, and (6) inner surface is provided with annular groove accordingly in the outer ring, and rolling element (7) is installed in the cavity that forms between the inside and outside groove.

2, flyer bearing according to claim 1 is characterized in that: sealing ring (8) is equipped with at the two ends in inner ring (5) and outer ring (6).
