Abstract

The utility model discloses a stainless steel wire rope in aviation, which is characterized by comprising a central strand, and further comprises an inner layer coated on the external part of the central portion. According to the rope, screw thread grooves are formed in the external part of the central strand; the outermost of the inner layer is coated with a protective layer; and the inner layer is formed by 5-13 inner layer strands of an edge. The rope has simple and exquisite structure, and high strength, greatly improves the load-bearing capacity, improves the fatigue resistance accordingly, and meanwhile, prolongs the service life, and improves the using property.

Description

Stainless steel wire rope in the aviation

Technical field

The utility model relates to the stainless steel wire rope in a kind of aviation.

Background technology

At present, be used for the stainless steel wire rope in the space flight, the steel wire twisting identical by diameter forms, for this reason, be the point-like contact between the adjacent wires, when steel wire rope winding reel or pulley bending, steel wire has been subjected to the pressure of crooked generation in strand, produce second order buckling, such steel wire rope just is easy to generate fatigue, causes the generation of fracture of wire phenomenon.Simultaneously, the power that such steel wire rope can bear is little, and anti-wear performance is also poor, and reduce service life greatly, has potential safety hazard.

Addressing these problems is extremely urgent as from the foregoing!

In view of this, the inventor has done deep research, and by feat of the experience of being engaged in relevant industries for many years and practice, design the stainless steel wire rope in a kind of aviation, exquisiteness simple in structure, intensity height, bearing capacity improves greatly, fatigue resistance also improves thereupon, increases the service life simultaneously and improves serviceability, and this case produces thus.

The utility model content

The purpose of this utility model is to provide the stainless steel wire rope in a kind of aviation, exquisiteness simple in structure, and the intensity height, bearing capacity improves greatly, and fatigue resistance also improves thereupon, increases the service life simultaneously and improves serviceability.

To achieve these goals, the technical solution of the utility model is as follows:

Stainless steel wire rope in the aviation; it is characterized in that: comprise a central strand, form thread groove in the outside of central strand, also comprise the internal layer that is coated on the central strand outside; ragged edge at internal layer coats protective layer, and described internal layer comprises that the internal layer thigh at 5-13 edge constitutes.

Further, described central strand is formed by 3 steel wire twistings.

Further, the structure of described internal layer thigh is that 3 or 5 steel wire twistings form.

Further, form tread plate in the outside of protective layer.

The beneficial effects of the utility model: the utility model comprises a central strand; outside in central strand forms thread groove; also comprise the internal layer that is coated on the central strand outside; ragged edge at internal layer coats protective layer, and described internal layer comprises that the internal layer thigh at 5-13 edge constitutes such setting; steel cord structure is tight; thread groove can play the embedding snap effect, also will increase inwall contact-making surface each other simultaneously, and then improves the steel wire rope bearing capacity.

Simultaneously, the bent fatigue performance of rope anti-bend is also getting raising, and softness and ABRASION RESISTANCE also improve, and are beneficial to long-run development, meet national space flight and use.

This shows, the utility model exquisiteness simple in structure, the intensity height, bearing capacity improves greatly, and fatigue resistance also improves thereupon, increases the service life simultaneously and improves serviceability.

In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 1; the utility model relates to the stainless steel wire rope in a kind of aviation; it is characterized in that: comprise a central strand 1; outside in central strand 1 forms thread groove; also comprise the internal layer that is coated on central strand 1 outside; ragged edge at internal layer coats protective layer 2, and described internal layer comprises that the internal layer thigh 3 at 5-13 edge constitutes.

Further arrange, described central strand 1 is formed by 3 steel wire twistings.

Further arrange, the structure of described internal layer thigh 3 is that 3 or 5 steel wire twistings form.

Further arrange, form tread plate in the outside of protective layer 2.

More than be that the technical scheme that the utility model embodiment provides is described in detail, having used specific case herein sets forth principle and the embodiment of the utility model embodiment, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all can change to some extent on the specific embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
