Abstract
A kind of composite ground roll shaft core, belongs to shaft core.Ground roll shaft core has some supports between inner cylinder and outer barrel, is supported on twist uniform between inner cylinder and outer barrel.The inner cylinder and outer barrel are cylindrical shape.The support is tabular spiral rotating muscle, and the spiral extension between inner cylinder and outer barrel, two ends are connected with inner cylinder and outer barrel simultaneously, and composition is integral.There are some support helix extension connections between inner cylinder and outer barrel, it is an entirety by spiral shape support, on the outer tube inner wall of the shaft core line parallel with axle, there are multiple spiral shape strong points, between inner cylinder and outer barrel to outer tube wall produce supporting role, greatly strengthen the intensity of beam barrel shape shaft core, light weight, rotatory inertia are small, outside cylinder precision is high, it is indeformable without alignment, shaping ground roll without mechanical wave, it is antistatic, corrosion-resistant, high temperature resistant；One-shot forming, reduction production process, energy-saving, manufacture maintenance cost are low, down time is short.Using 3D printing global formation, shaft core of the present utility model is produced.
Description
Technical field
The utility model is related to a kind of shaft core, more particularly to a kind of composite ground roll shaft core.
Background technology
Ground roll have many uses it is general, the fields such as printing machinery, textile machine, mining industry, chemical industry, space flight all be unable to do without ground roll.
It is the roll driving parts above installation and driving shaft in textile machine ground roll, its effect is will by rolling friction
Fiber carries out drawing-off, with profit weaving.But at work because ground roll and fiber contacts friction produce electrostatic, thus in ground roll
Circumference long face meeting absorbed portion fiber, reduces the Draft Effect of fiber, is so accomplished by artificial constantly removing, Comparision fiber crops
It is tired, and then difficulty is caused to the producer.Ground roll does not reach ideal effect much yet in other industries, general ground roll be by
The pig iron, steel part are fabricated by, and ground roll quality is especially weighed.Apply in textile industry, the damage of described ground roll to fiber is larger, directly
The uniformity of influence output sliver.
Current ground roll is real cored structure, and the shortcoming existed is：Weight is heavy, rotatory inertia is big, manufacturing process is complicated, precision
Low, high energy consumption, mechanical wave are big, service life is short, maintenance cost is big, down time is long, so as to influence product quality and output.
Utility model content
The purpose of this utility model is with being to provide for a kind of ultra lightweight, performance stabilization, the composite of service life length
Roll shaft core.
What the technical solution of the utility model was realized in：Ground roll shaft core includes：Outer barrel, inner cylinder and support；Inner cylinder with
Outer barrel with one heart, has some supports between inner cylinder and outer barrel, is supported on twist uniform between inner cylinder and outer barrel.
Described inner cylinder and outer barrel is cylindrical shape.
Described support be multiple tabular spiral rotating gussets, the spiral extension between inner cylinder and outer barrel, two ends are simultaneously
It is connected with inner cylinder and outer barrel, composition is integral.
Beneficial effect and advantage：There are some support helix extension connections between inner cylinder and outer barrel, be one by spiral shape support
Individual entirety, on the outer tube wall of the shaft core line parallel with axle, has multiple spiral shape strong points, to outer barrel between inner cylinder and outer barrel
Wall produces supporting role, greatly strengthen the intensity of beam barrel shape shaft core, and light weight, intensity are high, rotatory inertia is small, outside cylinder precision
It is high, indeformable without alignment, shaping ground roll without mechanical wave, antistatic, corrosion-resistant, high temperature resistant；One-shot forming, reduces and makes work
Sequence, energy-saving, manufacture maintenance cost are low, down time is short.It is overall using 3D printing so as to improve product quality and output
Shaping, produces shaft core of the present utility model, and the technique such as casting at present, injection, drawing can not be realized；Fill up domestic and international
One, ground roll field blank.
Brief description of the drawings
Fig. 1 is the utility model partial cutaway schematic perspective view.
Fig. 2 is the utility model Fig. 1 left view schematic diagram.
Fig. 3 is the utility model floor map.
In figure, 1, inner cylinder；2nd, support；3rd, outer barrel.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings：
Embodiment 1：Ground roll shaft core includes：Outer barrel 3, inner cylinder 1 and support 2；Inner cylinder 1 and outer barrel 3 are concentric, in inner cylinder 1 and outside
There are some supports 2 between cylinder 3, support 2 is twist uniform between inner cylinder 1 and outer barrel 3.
Described inner cylinder 1 and outer barrel 3 is cylindrical shape.
Described support 2 is multiple tabular spiral rotating gussets, and the spiral extension between inner cylinder 1 and outer barrel 3, two ends are same
When be connected with inner cylinder 1 and outer barrel 3, composition is integral.
Claims (3)
1. a kind of composite ground roll shaft core, it is characterized in that：Ground roll shaft core includes：Outer barrel, inner cylinder and support；Inner cylinder is same with outer barrel
The heart, there is some supports between inner cylinder and outer barrel, is supported on twist uniform between inner cylinder and outer barrel.
2. a kind of composite ground roll shaft core according to claim 1, it is characterized in that：Described inner cylinder and outer barrel is circle
Tubular.
3. a kind of composite ground roll shaft core according to claim 1, it is characterized in that：Described support is multiple tabular spiral shells
Rotation rotation gusset, the spiral extension between inner cylinder and outer barrel, two ends are connected with inner cylinder and outer barrel simultaneously, and composition is integral.
