Abstract
The utility model discloses a kind of novel transition doffer, described cylinder comprises the cylindrical shell with hollow cavity, wear the mandrel of the band shaft shoulder by described cylinder lumen vertically, be set in the antifriction-bearing box on described mandrel, described antifriction-bearing box has inner ring and outer ring, the shaft shoulder setting of described mandrel is close in the axis inner side of the described inner ring of described antifriction-bearing box, described cylinder also comprises the end cap arranged that matches with described antifriction-bearing box be installed in described cylinder lumen, the axially inner side setting of described end cap is close in the axis outside of the described outer ring of described antifriction-bearing box.This roller frame is simple, ensure that cylinder rotates flexibly in situation, improve rigidity and the stability of cylinder.
Description
Technical field
the utility model relates to packing technique field, the novel transition doffer particularly in a kind of case course of conveying.
Background technology
at present, in packing technique field, traditional transition roller frame is mainly made up of axle, antifriction-bearing box, stack shell, and bearing adopts back-up ring to fix, as accompanying drawing 1.When the diameter of stack shell is less than 12mm, then the diameter of the axle that cylinder is used need be less than 6mm, and now the elasticity of shaft block ring is poor, and this structure there will be back-up ring and loosens, and card does not live the situation of bearing, and meanwhile, the back-up ring draw-in groove of small axle diameter weakens the rigidity of axle.
Summary of the invention
the purpose of this utility model is to provide a kind of novel transition doffer for case conveying, and the structure of this cylinder is simple, good rigidly, good stability.
for achieving the above object, the technical solution adopted in the utility model is: a kind of novel transition doffer, described cylinder comprises the cylindrical shell with hollow cavity, wear the mandrel of the band shaft shoulder by described cylinder lumen vertically, be set in the antifriction-bearing box on described mandrel, described antifriction-bearing box has inner ring and outer ring, the shaft shoulder setting of described mandrel is close in the axis inner side of the described inner ring of described antifriction-bearing box, described cylinder also comprises the end cap arranged that matches with described antifriction-bearing box be installed in described cylinder lumen, the axially inner side setting of described end cap is close in the axis outside of the described outer ring of described antifriction-bearing box.
preferably, the radial outer side of described end cap and the madial wall phase interference fit of described cylindrical shell.
further preferably, described end cap is set on described mandrel, and there is gap between all lateral walls of the radially inner side of described end cap and described mandrel.
preferably, described antifriction-bearing box, described end cap, described mandrel and described cylindrical shell coaxial inner conductor are arranged.
due to the utilization of technique scheme, the utility model compared with prior art has following advantages: transition doffer of the present utility model, by being arranged on the end cap in cylinder lumen and antifriction-bearing box is fixed by the shaft shoulder on mandrel, by this setting, guaranteeing that cylinder rotates flexibly simultaneously, improve rigidity and the stability of cylinder, effectively prevent in prior art when adopting back-up ring to be fixed bearing, occur that back-up ring loosens, the phenomenon of card incessantly bearing occurs.
Accompanying drawing explanation
accompanying drawing 1 is the structural representation adopting back-up ring to be fixed bearing in prior art;
accompanying drawing 2 is the structural representation of novel transition doffer described in the utility model;
wherein: 1, cylindrical shell; 2, mandrel; 3, antifriction-bearing box; 4, back-up ring; 5, end cap.
Detailed description of the invention
below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is further elaborated.
shown in Figure 2, a kind of novel transition doffer, this cylinder comprises the cylindrical shell 1 with hollow cavity, the mandrel 2 wearing the band shaft shoulder by this cylindrical shell 1 inner chamber vertically, is set in the antifriction-bearing box 3 on mandrel 2 and is fixedly installed on the end cap 5 arranged that matches with antifriction-bearing box 3 in cylindrical shell 1 inner chamber.
shown in Figure 2, antifriction-bearing box 3 has inner ring and outer ring, the shaft shoulder setting of mandrel 2 is close in the axis inner side of this antifriction-bearing box 3 inner ring, the axially inner side setting of end cap 5 is close in the axis outside of this antifriction-bearing box 3 outer ring, by end cap 5 and the shaft shoulder on mandrel 2, antifriction-bearing box 3 is fixed, prevent cylinder in the course of the work, antifriction-bearing box 3 occurs to loosen.Here, end cap 5 is set on mandrel 2, and there is certain interval between all lateral walls of the radially inner side of end cap 5 and mandrel 2, make this cylinder flexibly rotatable in the course of the work, the radial outer side of end cap 5 then with the madial wall phase interference fit of cylindrical shell 1, in case occur to loosen in rotation process, thus the phenomenon causing card not live bearing occurs.
as the preferred mode of one, in the present embodiment, this antifriction-bearing box 3, end cap 5, mandrel 2 are arranged with cylindrical shell 1 coaxial inner conductor.
novel transition doffer of the present utility model, by being fixedly installed on the end cap in cylinder lumen, antifriction-bearing box is effectively fixed by the shaft shoulder on mandrel, in case in drum functions process, there is the phenomenon that antifriction-bearing box loosens, and then affect the work efficiency of cylinder, also ensure the rigidity of cylinder simultaneously, and between end cap and cylindrical shell madial wall, take interference fit, ensure that stable while decrease the use of parts.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
