Abstract
The invention relates to a sleeve joint part on a drawing mandrel, in particular to a rolling needle bearing structure in the sleeve joint part on the drawing mandrel and belongs to the technical field of manufacture of special spinning bearing parts. The sleeve joint part comprises an outer bearing ring, a rolling needle and a rolling needle retainer, the length of the rolling needle is 30mm. The rolling needle is embedded in the rolling needle retainer. The rolling needle and the rolling needle retainer are mounted in the outer bearing ring, and the rolling needle can bindingly roll in an inner hole of the outer bearing ring. Since the working length of the rolling needle bearing is increased, bearing capability of the bearing is improved, the service life of the bearing can be prolonged multiply, and the service period of the drawing mandrel fittingly used with the sleeve joint part can be effectively prolonged. The sleeve joint part has the advantages of high bearing capability, long service life, simplicity in assembly process, and the like.
Description
Technical field
The present invention relates in the spinning drawing-out machinery to support the needle bearing structure in the drawing sleeve joint member, particularly a kind of drawing sleeve joint member of drawing belt roller mandrel rotation, belong to the special part manufacturing technology of weaving bearing field.
Background technique
The bearing that is used for supporting the rotation of drawing belt roller mandrel in the tradition drawing sleeve joint member, generally select two needle bearings as the end of rolling element rotary support at the drafting mandrel, this rotary support form exists that supporting surface is little, the carrying of bearing is large, easily wearing and tearing, thereby makes the working life of bearing short.And the assembling of conjunction is complicated, the coaxality between two bearings can not be guaranteed, the urgent once again in advance inefficacy of bearing.Because the wearing and tearing of bearing are urgent, caused again the wearing and tearing of the drafting mandrel cylindrical used as bearing inner race suddenly anxious, caused in pairs subscription rate in advance of bearing and mandrel.Increase spinning cost and spinning quality and also can not get due assurance.Therefore, design a kind of working life of Effective Raise drawing sleeve joint member bearing, the drawing sleeve joint member bearing that effectively prolongs drafting skin axle mandrel life cycle is significant.
Summary of the invention
The abrasion serious problems that exist in order to overcome existing drawing sleeve joint member bearing the invention provides the sleeve joint member on a kind of drafting mandrel.
It is realized in the following ways: it comprises bearing outer ring, needle roller and cages for needle, and the length of described needle roller is 30mm; Described needle roller inlays in cages for needle; Described needle roller and cages for needle are contained in the bearing outer ring and needle roller can be done the constraint rolling in the endoporus of bearing outer ring.Because the present invention has increased the active length of needle bearing, thereby the bearing capacity of bearing is strengthened, can not only be at double in the working life of improving bearing, the life cycle that can also effectively prolong the drafting mandrel that is mated use.
The advantages such as the present invention has that carrying is large, the assembly technology of long service life, conjunction is simple.
Description of drawings
Accompanying drawing 2 is the present invention's working state figure in actual use.
In accompanying drawing 1: 1 bearing case, 2 needle rollers, 3 cages for needles.
In accompanying drawing 2: 4 sleeves, 5 ball pads, 6 packing rings, 7 steel balls, 8 jump rings, 9 drafting mandrels.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Shown in the accompanying drawing 1, selecting length is that 30mm, diameter are that the needle roller 2 of ￠ 2.8mm is as the rolling element of bearing.Cages for needle 3 is put into the hole of bearing case 1, with special vice 2 one ground of needle roller are inlayed in cages for needle 3, namely become the integral body of a needle bearing.
Shown in the accompanying drawing 2, the ball pad 5 of packing into successively in endoporus the inner of sleeve 4, the integral body that embeds steel ball 7, fills up upper gasket 6, needle bearing are at last with jump ring 8 axial restraints.Insert again drafting mandrel 9 as the external cylindrical surface of rolling support, namely form the working state of drafting mandrel and bearing sleeve connected member.Because the present invention adopts long needle bearing as the rotatably supported rolling element of drafting mandrel, so that the bearing length of needle roller has increased by 1/3rd more than, thereby makes the bearing capacity of sleeve connected member also increase 1/3.Corresponding, the supporting surface of drafting mandrel also increases synchronously.Therefore, obtained effective raising the working life of drafting mandrel and sleeve connected member.
Claims (3)
1. the sleeve joint member on the drafting mandrel, it comprises bearing outer ring, needle roller and cages for needle, the length of described needle roller is 30mm.
2. the sleeve joint member on a kind of drafting mandrel according to claim 1 is characterized in that described needle roller inlays in cages for needle.
According to claim 1 with 2 described a kind of drafting mandrels on sleeve joint member, it is characterized in that described needle roller and cages for needle are contained in the bearing outer ring and needle roller can be done the constraint rolling in the endoporus of bearing outer ring.
