Abstract
The utility model discloses a coupling with an anti-loosening function. The coupling with the anti-loosening function comprises a sleeve and a flange, a circular protrusion is arranged on the end portion of the sleeve, a pressing wall is further arranged on the end portion of the sleeve, a groove is formed in the pressing wall, and an elastic piece is installed inside the groove. The coupling with the anti-loosening function can limit the loosening of the connection between a shaft and the coupling, limits the radial displacement of the shaft, and meanwhile reduces the abrasion between the shaft and the coupling.
Description
Technical field
The utility model relates to the coupling technical field.
Background technique
It is multiplex bearing pin Placement that present coupling is connected with axle, and long-term the use then become flexible easily.。
The model utility content
The utility model provides a kind of coupling with anti-loosening function, can restrictive axes with coupling between be connected loosening, the radial displacement of restrictive axes has reduced the wearing and tearing between axle and the coupling simultaneously.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of coupling with anti-loosening function comprises sleeve and flange, is provided with circular protrusions in the end of described sleeve, also is provided with the compression wall in the end of described sleeve, is provided with groove at described compression wall, in described groove elastic component is installed.
Further, described circular protrusions has four, evenly distributes around the end of described sleeve.
Further, described compression wall stretches out the end of described sleeve, along the outer distribution of sleeve ends.
Further, described groove and two are arranged side by side at described compression wall inboard.
Further, described elastic component is spring.
Further, be coated with wearing layer in the end of described sleeve.
The utility model is by the design to coupling end circular protrusions, so that the stepped portions groove fit of circular protrusions and axle, it is spacing to realize that the relative coupling of axle moves radially, design to the compression wall that is provided with elastic component, realization is to the compression of axle, so that axle can in use not produce the mobile wearing and tearing that cause between pin and the groove.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the described a kind of plan view with coupling of anti-loosening function of the utility model embodiment.
Fig. 2 is the described a kind of plan view with coupling of anti-loosening function of the utility model embodiment.
Embodiment
As depicted in figs. 1 and 2, the described a kind of coupling with anti-loosening function of the utility model embodiment, comprise sleeve 1 and flange 2, be provided with circular protrusions 11 in the end of sleeve 1, also be provided with compression wall 12 in the end of sleeve, be provided with groove 121 at compression wall 12, elastic component 122 is installed in groove 121.
Compress the end that wall 12 stretches out sleeve 1, along the outer distribution of sleeve 1 end.
Groove 121 and two are arranged side by side and are compressing wall 12 inboards.
Elastic component 122 is spring.
Be coated with wearing layer 13 in the end of sleeve.
The utility model is by the design to coupling end circular protrusions, so that the stepped portions groove fit of circular protrusions and axle, it is spacing to realize that the relative coupling of axle moves radially, design to the compression wall that is provided with elastic component, realization is to the compression of axle, so that axle can in use not produce the mobile wearing and tearing that cause between pin and the groove.
