Abstract
The invention discloses a hollow flexible shaft of flat steel wires, comprising at least two layers of spiral rings sheathed coaxially, each layer of the spiral ring is formed by spirally winding 4-12 flat steel wires around the same shaft axis side by side, and the winding directions of the flat steel wires of the two adjacent layers of the spiral ring are opposite. By winding the hollow flexible shaft with the flat steel wires instead of conventional round steel wires, the torsional strength of the flexible hollow shaft is enhanced, and the hollow space is sufficient to accommodate more mediums, and the hollow flexible shaft can be popularized to multiple fields.
Description
Technical field
The invention belongs to mechanical transmission fields, relate in particular to a kind of flexible hollow shaft of flat wire.
Background technique
At present, existing flexible hollow shaft is by the Round Steel Wire coiled, such as the Hollow soft roller wire core of Chinese patent CN 2302280Y record, by steel wire coiled more than 2 layers, the steel wire wound opposite direction of adjacent layer, it has solved for example problem in working life of odometer price-marking weigher to a certain extent.In recent years, all use flexible hollow shaft in medical treatment, probing, high energy field, basic principle is exactly to rely on the hollow space of flexible hollow shaft to carry or bearing medium is realized the operation of complex environment.But, use the flexible hollow shaft of Round Steel Wire coiled in actual use, because there are the problem that working life is short or working space is limited 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 firmness change is little when stressed, and deformation uniformity is good, and plasticity and toughness are high, fatigue life high.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the objective of the invention is to propose a kind of flexible hollow shaft of flat wire that improves twisting strength and increase working space.
Purpose of the present invention will be achieved by the following technical programs:
A kind of flexible hollow shaft of flat wire, described flexible hollow shaft of flat wire comprises the coil of at least 2 layers of coaxial package, and described every layer of coil formed around same shaft axis spiral winding by flat wire, and the winding direction of the flat wire of adjacent two layers coil is relatively reverse.
Preferably, above-mentioned flexible hollow shaft of flat wire, wherein: described every layer of coil by 4～12 flat wires around same shaft axis side by side spiral winding form.
The present invention utilizes flat wire to substitute traditional Round Steel Wire coiling flexible hollow shaft, strengthened the twisting strength of flexible hollow shaft according to the structural feature of flat wire, and structure can be accomplished more exquisite, flexible hollow shaft than the coiling of same specification Round Steel Wire improves a lot at moment of torsion, and hollow space is more abundant, can hold more medium.Flexible hollow shaft of flat wire of the present invention has solved the problem of short and working space restriction in existing flexible hollow shaft working life, remedied existing structure in new field, such as the deficiency of orthopedic driling machine, existence when medical field uses, can be generalized to more field and use.
Following constipation closes embodiment's accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1;
Fig. 2 is the structural representation of the embodiment of the invention 2.
Embodiment
Embodiment 1:
A kind of flexible hollow shaft of flat wire of the present embodiment, as shown in Figure 1, the coil 1 that comprises 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 winding form, flat wire 2 side by side is to twine around a shaft axis by the I-beam wheel that a cover can be placed side by side to finish rule compositor.The winding direction of coil 1 flat wire 2 of adjacent two layers is relatively reverse.
The present embodiment utilizes flat wire 2 to substitute traditional Round Steel Wire coiling flexible hollow shaft, strengthened the twisting strength of flexible hollow shaft according to the structural feature of flat wire 2, and structure can be accomplished more exquisite, flexible hollow shaft than the coiling of same specification Round Steel Wire improves a lot at moment of torsion, and hollow space is more abundant, can hold more medium.
Embodiment 2:
A kind of flexible hollow shaft of flat wire of the 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 winding form, flat wire 5 side by side is to twine around a shaft axis by the I-beam wheel that a cover can be placed side by side to finish rule compositor.The winding direction of coil 3 and 4 flat wire 5 is relative reverse.
It is quiet that the flexible hollow shaft of flat wire 5 coilings of the present embodiment has running, sheathed is strong, and twisting resistance is large, the characteristics of spatial structure exquisiteness, the flexible hollow shaft of same size flat wire coiling increases about 5 times than the moment of torsion of the flexible hollow shaft of Round Steel Wire coiling, and the inner space increases approximately 1/3.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technological schemes of forming all drop within protection scope of the present invention.
