Abstract
The invention discloses a high-reliability lifting equipment coupling, which comprises bolts, a first shaft sleeve, a high-reliability layer, nuts, a second shaft sleeve and a centering key. Each bolt is matched with a nut with a corresponding size. The bolts penetrate through and are connected through connecting holes in the first shaft sleeve and the second shaft sleeve. The high-reliability layer is a rubber layer and is arranged on the inner sides of the two shaft sleeves. The centering key is arranged in the middle of the first shaft sleeve and the second shaft sleeve. By adopting the arrangement, not only can the overall material for making the coupling be saved and can the cost be decreased, but also the reliability of the coupling can be greatly improved.
Description
Technical field
The present invention relates to a kind of crane gear coupling, particularly relate to a kind of high reliability crane gear coupling.
Background technique
Present stage, crane gear has generally applied to each construction site, crane gear slowly will rely on the mode of electric power to replace using manpower to carry out operation simultaneously, once apply to electric power, transmission performance in crane gear between each axle is poor, and the article of adding the crane gear lifting are generally heavier, and general coupling causes the interaction force between axle and axle larger, it is unreliable, fragile to operate.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high reliability crane gear coupling, not only can save the material of coupling integral body, reduces costs, and can also improve significantly the reliability of coupling.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of high reliability crane gear coupling is provided, comprise: bolt, the first axle sleeve, high reliability layer, nut, the second axle sleeve, centering key, the nut of a corresponding size of described bolt coupling, and run through the attachment hole be connected on the first axle sleeve and the second axle sleeve, described high reliability layer is a rubber layer, is positioned at two axle sleeve inboards, and described centering key is positioned in the middle of the first axle sleeve and the second axle sleeve.
In a preferred embodiment of the present invention, the big or small position of the attachment hole on described the first axle sleeve and the second axle sleeve is all identical.
In a preferred embodiment of the present invention, the length of described bolt is greater than the length sum that diaxon puts attachment hole.
Beneficial effect of the present invention: the present invention adopts the high reliability layer of a rubber material is set in the axle sleeve inboard, saved the cost of material of coupling, added that the external world has bolt to fix simultaneously, made coupling when running, the suffered power of axle declines to a great extent, thereby improves the reliability of coupling.
The accompanying drawing explanation
Fig. 1 is the structural representation of the present invention in a preferred embodiment.
In figure, each assembly and reference character are respectively: 1, bolt, the 2, first axle sleeve, 3, the high reliability layer, 4, nut, the 5, second axle sleeve, 6, centering key, 7, attachment hole.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Please refer to Fig. 1 in an embodiment of the present invention, a kind of high reliability crane gear coupling, comprise: bolt (1), the first axle sleeve (2), high reliability layer (3), nut (4), the second axle sleeve (5), centering key (6), attachment hole (7), described bolt (1) mates the nut (4) of a corresponding size, and run through the attachment hole (7) be connected on the first axle sleeve (2) and the second axle sleeve (5), described high reliability layer (3) is a rubber layer, be positioned at two axle sleeve inboards, described centering key (6) is positioned in the middle of the first axle sleeve (2) and the second axle sleeve (5).
Further illustrate, at first by centering key (6), the attachment hole (7) of the first axle sleeve (2) and the second axle sleeve (5) is aimed at, then use bolt (1) through attachment hole (7), use again nut (4) by its locking, after coupling connects diaxon, while starting to rotate, because the high reliability layer (3) of rubber material is equipped with in the axle sleeve inboard, make axle more safe and reliable when rotating.
In another preferred embodiment of the present invention, the big or small position of the attachment hole (7) on described the first axle sleeve (2) and the second axle sleeve (5) is all identical.
Further illustrate, because the first axle sleeve (2) runs through and is connected with nut (4) by bolt (1) with the second axle sleeve (5), if the size of attachment hole (7) is not identical with position, bolt (1) just can't pass attachment hole (7) so, thereby two axle sleeves can't be fixed together.
In another preferred embodiment of the present invention, the length of described bolt (1) is greater than the length sum that diaxon puts attachment hole (7).
Further illustrate, only have the length of bolt (1) to be greater than the length sum that diaxon puts attachment hole (7), could use bolt (1) by the tightly locking of diaxon cover, improve the coupling reliability.
The present invention not only can save the material of coupling integral body, reduces costs, and can also improve significantly the reliability of coupling.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
Claims (3)
1. a high reliability crane gear coupling, it is characterized in that: comprising: bolt (1), the first axle sleeve (2), high reliability layer (3), nut (4), the second axle sleeve (5), centering key (6), attachment hole (7), described bolt (1) mates the nut (4) of a corresponding size, and run through the attachment hole (7) be connected on the first axle sleeve (2) and the second axle sleeve (5), described high reliability layer (3) is a rubber layer, be positioned at two axle sleeve inboards, described centering key (6) is positioned in the middle of the first axle sleeve and the second axle sleeve (5).
2. a kind of high reliability crane gear coupling according to claim 1, it is characterized in that: the big or small position of the attachment hole (7) on described the first axle sleeve (2) and the second axle sleeve (5) is all identical.
3. a kind of high reliability crane gear coupling according to claim 1, it is characterized in that: the length of described bolt (1) is greater than the length sum that diaxon puts attachment hole (7).
