Abstract
The utility model discloses a flexible hollow shaft of a flat wire, comprising at least two layers of spiral rings sheathed coaxially, each layer of the spiral ring is formed by spirally winding 4-12 flat wires around the same axial lead side by side, the winding directions of the flat wires of the two adjacent layers of the spiral ring are opposite. In the utility model, the flat wires are adopted to replace the traditional round wires to wind the flexible hollow shaft, the torsional strength of the flexible hollow shaft is enhanced, and the hollow space is sufficient to contain more mediums, so that the flexible hollow shaft can be widely popularized to multiple fields.
Description
Technical field
The utility model belongs to mechanical transmission fields, relates in particular to the hollow flexible axle of a kind of flat wire.
Background technique
At present; Existing hollow flexible axle is by the Round Steel Wire coiled, like the Hollow soft roller wire core of Chinese patent CN 2302280Y record, by steel wire coiled more than 2 layers; The steel wire coiling of adjacent layer is in the opposite direction, and it has solved the for example problem in working life of odometer price-marking weigher to a certain extent.In recent years, all use hollow flexible axle in medical treatment, probing, high energy field, basic principle is exactly to rely on the hollow space of hollow flexible axle to carry the perhaps operation of bearing medium realization complex environment.But, with the hollow flexible axle of Round Steel Wire coiled in actual use, because there are the short or limited problem of working space in working life in moment of torsion deficiency own and structural limitations.Flat wire is a kind of in the section wire, can bear stronger torsion compared to Round Steel Wire, has less section thickness, and the section of steel wire hardness variation is little when stressed, and deformation uniformity is good, and plasticity and toughness are high, fatigue life characteristics such as height.
The model utility content
In view of the defective that above-mentioned existing technology exists, the purpose of the utility model is to propose a kind of twisting strength and hollow flexible axle of flat wire that increases working space of improving.
The purpose of the utility model will be achieved through following technological scheme:
The hollow flexible axle of a kind of flat wire, the hollow flexible axle of said flat wire comprises the coil of at least 2 layers of coaxial package, and said every layer of coil is entwined around same shaft axis spiral by flat wire, and the winding direction of the flat wire of adjacent two layers coil is reverse relatively.
Preferably, the hollow flexible axle of above-mentioned flat wire, wherein: said every layer of coil by 4～12 flat wires around same shaft axis side by side spiral be entwined.
The utility model utilizes flat wire to substitute traditional hollow flexible axle of Round Steel Wire coiling; Strengthened the twisting strength of hollow flexible axle according to the structural feature of flat wire; And can structure be accomplished more exquisite; Hollow flexible axle than the coiling of same specification Round Steel Wire improves on moment of torsion a lot, and hollow space is more abundant, can hold more medium.The hollow flexible axle of the flat wire of the utility model has solved the problem of existing hollow flexible axle weak point in working life and working space restriction; Remedied existing structure in new field; The deficiency that exists during like orthopedic driling machine, medical field utilization makes it can be generalized to more field and uses.
Following constipation closes embodiment's accompanying drawing, the embodiment of the utility model is done further to detail, so that the utility model technological scheme is easier to understand, grasp.

Fig. 1 is the utility model embodiment 1 a structural representation;
Fig. 2 is the utility model embodiment 2 a structural representation.
Embodiment
Embodiment 1:
The hollow flexible axle of a kind of flat wire of present embodiment, as shown in Figure 1, comprise the coil 1 of 6 layers of coaxial package; From the inside to the outside, every layer of coil 1 is by 4,9; 7; 11,12 and 12 flat wires 2 around same shaft axis side by side spiral be entwined, flat wire 2 side by side is that the I-beam wheel of leaning on a cover to be arranged side by side is twined around a shaft axis and accomplished rule compositor.The winding direction of coil 1 flat wire 2 of adjacent two layers is reverse relatively.
Present embodiment utilizes flat wire 2 to substitute traditional hollow flexible axle of Round Steel Wire coiling; Strengthened the twisting strength of hollow flexible axle according to the structural feature of flat wire 2; And can structure be accomplished more exquisite; Hollow flexible axle than the coiling of same specification Round Steel Wire improves on moment of torsion a lot, and hollow space is more abundant, can hold more medium.
Embodiment 2:
The hollow flexible axle of a kind of flat wire of present embodiment; With embodiment's 1 structural similarity; As shown in Figure 2; The coil 3 and 4 that comprises 2 layers of coaxial package, coil 3 and 4 by 4～12 flat wires 5 around same shaft axis side by side spiral be entwined, flat wire 5 side by side is that the I-beam wheel of leaning on a cover to be arranged side by side is twined around a shaft axis and accomplished rule compositor.The winding direction of coil 3 and 4 flat wire 5 is reverse relatively.
It is quiet that the hollow flexible axle of flat wire 5 coilings of present embodiment has running; Sheathed is strong, and twisting resistance is big, the characteristics that spatial structure is exquisite; The hollow flexible axle of same size flat wire coiling increases about 5 times than the moment of torsion of the hollow flexible axle of Round Steel Wire coiling, and the inner space increases about 1/3.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technological schemes of forming all drop within the protection domain of the utility model.
Claims (2)
1. hollow flexible axle of flat wire; It is characterized in that: the hollow flexible axle of said flat wire comprises the coil of at least 2 layers of coaxial package; Said every layer of coil is entwined around same shaft axis spiral by flat wire, and the winding direction of the flat wire of adjacent two layers coil is reverse relatively.
2. the hollow flexible axle of flat wire according to claim 1 is characterized in that: said every layer of coil by 4～12 flat wires around same shaft axis side by side spiral be entwined.
