Abstract
The utility model relates to a kind of box coupling structure, comprises sleeve, and sleeve two ends have the endoporus for connecting live axle and coupking shaft respectively, and on the outer wall of described sleeve two ends, cover has retainer ring or is coated with retainer ring/steel wire respectively.Compared with prior art, its technique effect is: described retainer ring plays the effect of fixed muffle when sleeve is heated deliquescing, distortion, make box coupling in heavy load, can not be out of shape and expand when high torsion and hot operation, even work long hours, sleeve strength also can improve more than 50% on original basis.With low cost, assembling mode is simple, and structural safety is reliable.
Description
Technical field
The utility model relates to the coupling of axle for two coaxial lines that are rigidly connected or other active machine elements.In particular to a kind of box coupling structure.
Background technique
The sleeve two ends of existing box coupling are the endoporus for connecting the first axle and the second axle respectively, and when machine is in high capacity work for a long time, the temperature rise at two ends can be delivered to sleeve simultaneously.Under the operating mode using flexible glue material at sleeve, when running into heavy load, high torsion, high temperature and work long hours flexible glue material sleeve can deliquescing, distortion expanding, now sleeve is just very weak, easy appearance is skidded, wearing and tearing or Decrepitation Phenomena, cause whole product to use, repair rate is high, brings inconvenience to user.
Summary of the invention
The technical problem to be solved in the present invention is to avoid the deficiencys such as the flexible glue material sleeve of coupling in prior art in use easy deliquescing, distortion or expansion, the utility model provides a kind of box coupling structure, in heavy load, can not be out of shape and expand when high torsion and hot operation.
The utility model solves the technological scheme that its technical problem adopts: provide a kind of box coupling structure, comprise sleeve, sleeve two ends have the endoporus for connecting the first axle and the second axle respectively, and on the outer wall of described sleeve two ends, cover has retainer ring respectively.
There is provided a kind of box coupling structure, comprise sleeve, sleeve two ends have the endoporus for connecting the first axle and the second axle respectively, and described sleeve two ends are coated with retainer ring respectively.
There is provided a kind of box coupling structure, comprise sleeve, sleeve two ends have the endoporus for connecting the first axle and the second axle respectively, and described sleeve two ends are coated with steel wire respectively.
Further, described first axle is motor power output shaft, and described second axle is worm screw.
Compared with prior art, the beneficial effects of the utility model are: make box coupling in heavy load, can not be out of shape and expand when high torsion and hot operation, even work long hours, sleeve strength also can improve more than 50% on original basis.And with low cost, assembling mode is simple, and structural safety is reliable.
Accompanying drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model embodiment;
Fig. 2 is the structural representation after the utility model embodiment assembling.
In figure: 1 be motor, 2 be retainer ring, 3 be magnetosphere, 4 be sleeve, 5 for worm screw.
embodimentbelow in conjunction with accompanying drawing, the utility model will be further described.
A kind of box coupling structure, comprise sleeve, sleeve two ends have the endoporus for connecting the first axle and the second axle respectively, and on the outer wall of described sleeve two ends, cover has retainer ring respectively.
See Fig. 1 and Fig. 2, specific embodiment of the utility model is used for the connection of motor 1 and worm screw 5.Sleeve 4 two ends are the endoporus for connecting motor reel and worm shaft respectively, and on the outer wall of described sleeve 4 two ends, cover has retainer ring 2 respectively.
Described retainer ring 2 plays the effect of fixed muffle 4 when sleeve 4 is heated deliquescing, distortion.Make sleeve 4 in heavy load, can not be out of shape and expand when high torsion and hot operation.
In other embodiments, the retainer ring of described sleeve two ends outer wall can substitute with the retainer ring be coated within sleeve two ends or the steel wire be coated within sleeve two ends.
Should be understood that, above embodiment only in order to technological scheme of the present invention to be described, is not intended to limit, for a person skilled in the art, technological scheme described in above-described embodiment can be modified, or equivalent replacement is carried out to wherein portion of techniques feature; And these amendments and replacement, all should belong to the protection domain of claims of the present invention.
