Abstract

The invention relates to a novel combing roller bearing which comprises an outer ring, wherein cages are equipped at the two ends of the interior of the outer ring and matched with balls; the balls are located in a ring-shaped concave groove formed in a core shaft; dustproof rings are mounted at the internal circumferences at the two ends of the outer ring; the outer ring is provided with ring-shaped grooves; the ring-shaped grooves are provided with oil feeding holes; oil feeding rings are sleeved with the ring-shaped grooves; a positioning ring is mounted at the external circumference at one end of the outer ring; after the bearing is pressed into a roller body, the end surface of the positioning ring is higher than that of the roller body. The novel combing roller bearing has a simple structure, and is high in running precision, less in abrasion and long in service life.

Description

Novel bearing for combing roller

Technical field

The present invention relates to technical field of bearings, especially a kind of for the bearing for combing roller on rotor spinning machine.

Background technique

For the bearing for combing roller on rotor spinning machine, mainly by outer ring, mandrel, retainer, rolling element (roller or ball), dust ring etc., formed; Due to position structure not being set on the outer ring of kind of bearings, when bearing is pressed into roll body, while putting into cup seat, when bearing runs up, roll body end face and cup seat be grazing mutually easily, cause bearing to wear and tear rapidly, precise decreasing and rotate the unstable surface that causes and produce overheated and burn inefficacy, reduces working life.

Summary of the invention

The applicant, for above-mentioned shortcoming of the prior art, provides a kind of novel bearing for combing roller, and it is simple in structure, and running accuracy is high, and wearing and tearing are few, long service life.

The technical solution adopted in the present invention is as follows:

Novel bearing for combing roller, comprises outer ring, and the two ends, inside of outer ring are with retainer, and retainer matches with ball, and ball is positioned at the circular groove on mandrel; The two ends inner circle of outer ring is equipped with dust ring, and on outer ring, with annular groove, described annular groove place, with tank filler sleeve, is placed on oiling ring in described annular groove; On one end cylindrical of outer ring, positioning ring is installed, bearing is pressed into after roll body, and the end face of positioning ring is higher than the end face of roll body;

Further technological scheme is as follows:

Preferably, on the cylindrical of outer ring with positioning ring cooperation place with the first caulking groove, in-built flexible of the first caulking groove; The inner circle of positioning ring is with the second caulking groove, and described elastic component is stuck in the second caulking groove;

Preferably, being positioned at cover in the inner spindle of outer ring has oil distributing ring, and the cylindrical of described oil distributing ring is connected with oil guide slot and with outer ring, and tank filler sleeve is positioned at the top of described oil guide slot;

Preferably, the external diameter of positioning ring is Φ 30～Φ 40mm, and width is 0.5～10mm;

Preferably, bearing is pressed into after roll body, and the end face distance that the end face of positioning ring exceeds roll body is 0.01～5mm.

Beneficial effect of the present invention is: the one end at bearing top circle arranges positioning ring, bearing is pressed into after roll body, the end face of positioning ring is higher than the end face of roll body, make to have gap between the end face of roll body and cup seat, prevented that bearing is when running up, between roll body end face and cup seat, bump, in order to avoid mandrel rotation imbalance causes bearing generation heavy wear; Bearing top circle has caulking groove, and with elastic component, elastic component snaps in the caulking groove of positioning ring inner circle positioning ring is positioned, and prevents that positioning ring is subjected to displacement, and guarantees that it is to the positioning precision between roll body and cup seat in caulking groove.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Fig. 2 is that the present invention is pressed into the view after roll body.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

As depicted in figs. 1 and 2, the present invention includes outer ring 6, the two ends, inside of outer ring 6 are with retainer 7, and retainer 7 matches with ball 8, and ball 8 is positioned at the circular groove on mandrel 1, the two ends inner circle of outer ring 6 is equipped with dust ring 2, and on outer ring 6, with annular groove, described annular groove place, with tank filler sleeve 5, is placed on oiling ring 4 in described annular groove, on one end cylindrical of outer ring 6, positioning ring 3 is installed, the external diameter of positioning ring 3 is Φ 30～Φ 40mm, width is 0.5～10mm, bearing is pressed into after roll body 11, the end face of positioning ring 3 is higher than the end face of roll body 11, the distance exceeding is 0.01～5mm, at bearing, pack into after cup seat, can play and make roll body 11 end faces and cup seat keep certain gap, avoid bumping between the two, prevent that heel and toe wear from appearring in bearing, extend its working life, positioning ring 3 has also reduced the gap between bearing outer ring 6 and roll body 11 endoporus, prevent that introduced contaminants from entering bearing inside, affect the running accuracy of bearing, preferably, on 6 cylindricals of outer ring with positioning ring 3 cooperation places with the first caulking groove 10, in-built flexible of the first caulking groove 10, the inner circle of positioning ring 3 is with the second caulking groove 9, described elastic component is stuck in the second caulking groove 9, the assembly precision that can guarantee positioning ring 3 and bearing outer ring 6, prevents that positioning ring 3 is offset, and then guarantees that it is to the positioning precision between roll body 11 and cup seat (not shown in FIG.), preferably, be positioned at cover in 6 inner spindle 1 of outer ring and have oil distributing ring (not shown in FIG.), the cylindrical of described oil distributing ring is connected with oil guide slot and with outer ring 6, gapped between described oil distributing ring and mandrel 1, prevent that described oil distributing ring from contacting with mandrel 1, affect the normal operation of bearing and mandrel 1 is caused to wearing and tearing, tank filler sleeve 5 is positioned at the top of described oil guide slot, can make lubricant oil accurately add the key positions such as ball 8 and retainer 7, when guaranteeing its lubrication effect, also reach fuel-efficient object.

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