Abstract
The utility model relates to a drawing leather-roller and bearing sleeve combining device and aims to solve the problems of mandrel deformation and bend due to the easy lap-up of a leather-roller mandrel, and bearing lubrication. In the utility model, a leather-roller lining sleeve is arranged between the leather roller and a needle bearing; the needle bearing is supported on the mandrel; two ends of the mandrel are supported on in the inner part of the sleeve, and the mandrel is connected with the sleeve in a sliding manner; and a group of limit steel balls are arranged between the leather-roller lining sleeve and the mandrel. The utility model has the advantages of prolonging of service life of a combining piece, improvement on quality of spinning, convenient maintenance, reduction of fuel consumption and the like.
Description
Technical field
The utility model relates in the spinning drawing-out machinery and being connected between the drafting roller and spring bearing, is applicable to the drawing frame roller bearing conjunction of various types.
Background technology
The drafting roller bearing conjunction of domestic production at present adopts the mode that rolling element is placed sleeve inner, realizes that the rotation of drafting roller mandrel is supported.Two needle bearings are contained in the sleeve hole, and the centre is separated by packing ring, are realized the axial restraint of bearing by spring collar.Drafting roller core in the conjunction is by the ball pad that is contained in the sleeve.Rolling axial location after realizing the roller mandrel and sleeve cooperating.The drafting roller bearing conjunction axial location low precision of this structure, roller mandrel very easily lap-ups makes the mandrel bending, causes sliver quality instability, as forms regular slub yarn or sudden yarn and shelter and increase flaw.Owing to bearing is contained in limited grease very fast dilution after bearing rotation heating of injecting the rolling element place is run off, thereby bearing wear out failure very easily.And mandrel and sleeve wear and tear urgent owing to the inefficacy of bearing equally.Want to solve the lubrication problem of above-mentioned bearing, unique way is often to think to inject in the bearing grease.And the oiling mode under this meeting general construction quite bothers.Do not take off conjunction, not dismantling conjunction can't grease up.This just causes the life-span of above-mentioned conjunction short.The maintenance work amount is big.Shortcomings such as oil consumption is many.
Summary of the invention
The purpose of this utility model is to propose a kind of drafting roller bearing sleeve combined device.It has overcome the serious problem of connecting portion abrasion of prior art.
The utility model is realized in the following ways: it is to be made of sleeve, mandrel, packing ring, spring collar, needle bearing, steel ball, roller, roller liner sleeve etc.It is characterized in that being provided with between roller and the needle bearing roller liner sleeve; Needle bearing is supported on the mandrel; The mandrel two end supports is in sleeve inner, and and sleeve between be slidingly connected; Be provided with one group of spacing steel ball between roller liner sleeve and the mandrel.
There is the rotation of in roller liner sleeve, doing between the raceway outside raceway and the mandrel to roll of two groups of needle rollers to support between mandrel, the roller liner sleeve.One group of steel ball is made the rolling axial location between roller liner sleeve septal fossula and mandrel outer fissure.Formed the double-row roller bearing under the special shape.Mandrel and gapped cooperation between the sleeve with rolling element not its objective is to allow the possibility that has the garden little change in Zhou Shouli position between mandrel and the sleeve, lower the unidirectional fixing stressed tendency of mandrel as much as possible.
To the oiling at rolling element place, the two ends of mandrel are provided with tank filler sleeve b for convenience, and this tank filler sleeve leads directly to the rolling element place, and is connected with the tank filler sleeve a of sleeve tail end.In use, then need not to dismantle conjunction and can on machine, implement timely oiling rolling element.
Drawing frame roller bearing conjunction provided by the utility model has tangible result of use, makes conjunction both keep original spinning technique requirement.Improved service life more than 6 times, be convenient to the manufacturing machining accuracy of conjunction again.
Description of drawings
Accompanying drawing is the utility model sectional structure schematic diagram
In the accompanying drawing: 1 sleeve, 2 mandrels, 3 packing rings, 4 spring collars, 5 needle bearings, 6 steel balls, 7 rollers, 8 roller liner sleeves, a, b are tank filler sleeve.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in the accompanying drawing, two groups of needle bearings 5 are arranged on has realized the rotation of roller 7 around mandrel 2 between roller liner sleeve 8 and the mandrel 2.The interior raceway groove that outer raceway groove that mandrel 2 outsides are provided with and roller liner sleeve 8 inboards are provided with is in order to the steel ball 6 of packing into, realizes axial rotary location between mandrel 2 and the roller liner sleeve 8 with this.Interior raceway two ends have the jump ring groove of the spring collar 4 of packing into, in order to the unsteady location of needle bearing 5.
The both ends of the surface center of mandrel 2 is provided with the b hole of ￠ 2mm, is connected with the vertical aperture that is located at outer raceway groove edge with the vertical aperture that is located at two outer raceway centers.Through being located at a hole of sleeve 1 tail end, can directly implement oiling to two groups of needle bearings 5 and one group of steel ball 6 place.
Place, the outer garden of the interface of sleeve 1 has the R groove, in order to the packing ring 3 of packing into.Thereby realize seamless sealing.
Cooperating between sleeve 1 and the mandrel 2 is H11/C11.
The rubber roll 7 at drawing frame roller bearing conjunction foreign work provided by the utility model position, with the rubber roll at traditional drafting roller bearing conjunction foreign work position, its shape and size are as good as.It has adopted and rolling element has been placed drafting roller in-core portion fully and sleeve 1 inside does not have the version of rolling element fully.The appropriate setting of sealing device and oil filler point had in addition both kept the original technical characteristic of conjunction, the service life that has strengthened conjunction again.Improve spinning quality, made things convenient for maintenance, reduced fuel consumption.
