The carding roller bearing is compact and reasonable in structure. The oiling structures are arranged on the core shaft, so that lubrication in the process of use of the bearing can be realized conveniently, and the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to the textile workpiece technical field, especially a kind of for the bearing for combing roller on the rotor spinning machine.
Background technique
In the prior art, the bearing for combing roller that is used on the rotor spinning machine mainly comprises outer ring, mandrel, retainer, rolling element (roller or ball), dust ring, positioning ring.Rolling element (roller or ball) is installed in employing between outer ring and mandrel, with retainer location, the even separation roller of retainer and maintenance rolling element proper exercise, dust ring is put in the dustproof groove of outer ring, and positioning ring plays the role of positioning.It is simple and reasonable for structure, but the bearing of this kind structure does not arrange rational Refuel structure, make bearing in the situation that the continuous high speed running, after using a period of time, because can causing bearing, oil starvation weares and teares rapidly, it is large that precise decreasing, noise become, and rotate and unstablely cause the surface to produce overheated and burn inefficacy, reduces working life.
Summary of the invention
The applicant in the above-mentioned existing production technology without Refuel structure, cause the shortcomings such as bearing working life is short, a kind of bearing for combing roller rational in infrastructure is provided, thereby the two ends at mandrel have increased respectively Refuel structure, make it when running up, and grease can in time add in the groove, the frictionalwear of rolling element and outer ring, mandrel in the minimizing bearing, increase the service life, improve the quality of spinning, reduce cost.
The technical solution adopted in the present invention is as follows:
A kind of bearing for combing roller comprises between outer ring and the mandrel rolling element is installed that retainer separation roller, dust ring are installed in the dustproof groove of outer ring, on the outer peripheral surface of positioning ring installation and outer ring; The two ends of described mandrel are respectively arranged with Refuel structure, and the two ends of described mandrel have axial tank filler sleeve, and the outer end that is positioned at axial tank filler sleeve is extended with counterbore, and the plug cock head is installed in the described counterbore; Be provided with the mandrel raceway groove on the described mandrel, the cylindrical place that is positioned at the mandrel at mandrel raceway groove two ends has the cylindrical groove, and has radial direction through hole along the position of cylindrical groove, and described radial direction through hole passes axial tank filler sleeve.
As further improvement in the technical proposal:
The diameter of described axial tank filler sleeve is Φ 0.1mm～Φ 16mm, and the length of described axial tank filler sleeve is 10mm～73mm;
The diameter of described radial direction through hole is: Φ 0.1mm～Φ 10mm; Described radial direction through hole to the distance between the mandrel outer end is 10mm～56mm;
Described cylindrical groove to the distance between the mandrel outer end is 10mm～56mm;
The diameter of described counterbore is Φ 0.1mm～Φ 16mm, and the length of described counterbore is 0.1mm～40mm.
Beneficial effect of the present invention is as follows:
Compact structure of the present invention, reasonable.By at mandrel Refuel structure being set, can realize easily the lubricated of bearing using process, increase the service life.
The present invention respectively has a plug cock head at mandrel two ends counterbore, bearing is after a period of time that runs up, in the time of will replenishing oiling to bearing, only need pull out the plug cock head, grease flows into radial direction through hole along axial tank filler sleeve, flow into the cylindrical groove by radial direction oil hole, since the cylindrical groove from the mandrel raceway groove very close to, grease is flowed in the bearing channel fast, uniformly, reduce the frictionalwear of rolling element and outer ring in the bearing for combing roller, mandrel, prolong the life-span of bearing for combing roller, improve the quality of spinning.
Description of drawings
Fig. 1 is structural representation of the present invention (whole-cutaway view).
Fig. 2 is the structural representation (whole-cutaway view) of mandrel of the present invention.
Wherein: 1, mandrel; 2, counterbore; 3, axial tank filler sleeve; 4, retainer; 5, radial direction through hole; 6, rolling element; 7, positioning ring; 8, outer ring; 9, dust ring; 10, mandrel raceway groove; 11, cylindrical groove.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the bearing for combing roller of the present embodiment comprises rolling element 6 is installed between outer ring 8 and the mandrel 1, retainer 4 separation rollers 6, and dust ring 9 is installed in the dustproof groove of outer ring 8, on the outer peripheral surface of positioning ring 7 installations and outer ring 8; The two ends of mandrel 1 are respectively arranged with Refuel structure, and the two ends of mandrel 1 have axial tank filler sleeve 3, and the outer end that is positioned at axial tank filler sleeve 3 is extended with counterbore 2, counterbore 2 interior installation plug cock heads (not shown in FIG.); Be provided with mandrel raceway groove 10 on the mandrel 1, the cylindrical place that is positioned at the mandrel 1 at mandrel raceway groove 10 two ends has cylindrical groove 11, and has radial direction through hole 5 along the position of cylindrical groove 11, and radial direction through hole 5 passes axial tank filler sleeve 3.
Axially the diameter of tank filler sleeve 3 is Φ 0.1mm～Φ 16mm, and axially the length of tank filler sleeve 3 is 10mm～73mm.
The diameter of radial direction through hole 5 is: Φ 0.1mm～Φ 10mm; Radial direction through hole 5 to the distance b between mandrel 1 outer end is 10mm～56mm.
The diameter of counterbore 2 is Φ 0.1mm～Φ 16mm, and the length of counterbore 2 is 0.1mm～40mm.
As depicted in figs. 1 and 2, in the actual using process, because the present invention is respectively having a plug cock head (not shown in FIG.) at mandrel 1 two ends counterbore 2 places, after bearing is running up a period of time, in the time of will replenishing oiling to bearing, only need pull out plug cock head (not shown in FIG.), grease flows into radial direction through hole 5 along axial tank filler sleeve 3, flow into cylindrical groove 11 by radial direction through hole 5, since cylindrical groove 11 from the mandrel raceway groove 10 of mandrel 1 very close to, make grease quick, flow in the bearing channel uniformly, thereby reduce rolling element 6 and outer ring 8 in the bearing for combing roller, the frictionalwear of mandrel 1, prolong the life-span of bearing for combing roller, improve the quality of spinning.
Above description is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
