Abstract
The utility model relates to a coupling for a winding drum. The coupling comprises a coupling body, wherein the coupling body comprises a connecting body and a stationary shaft body; the outer ring face of the stationary shaft body is provided with a fixed ring plate which is connected with an end face of the winding drum; the connecting body and the stationary shaft body are provided with communicated inner holes; and the inner ring face of the stationary shaft body is provided with a pair of key ways. By arranging a pair of key ways in the inner ring face of the stationary shaft body of a part connected with a rotating shaft in the coupling, the rotating shaft is stressed in a balanced manner during connection, the stability of the coupling is improved, and the service life of the coupling is prolonged.
Description
Technical field
The utility model relates to a kind of reel coupling.
Background technique
Reel is used for rotating shaft with coupling and reel links together, thereby realize rotating shaft band movable reel is rotated together, traditional reel only has one with the keyway that dead axle in the coupling partly is used for being connected with rotating shaft, what be connected between rotating shaft and the coupling like this is just not steady, utility time the phenomenon that rotating shaft and coupling become flexible can occur once long, slowly just stayed potential safety hazard.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of reel coupling is provided, solve traditional a kind of reel and be connected unsettled defective with between coupling shaft and the coupling.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of reel coupling, comprise the coupling body, described coupling body comprises connection body and dead axle body, be provided with the fixedly girth sheets that is connected for the reel end face on the outer ring face of described dead axle body, described connection body and dead axle body have the endoporus that communicates, and are provided with a pair of keyway on the inner ring face of described dead axle body.
Further, described connection body, dead axle body and fixedly girth sheets be structure as a whole.
Further, be provided with bolt hole on the described fixedly girth sheets.
The beneficial effects of the utility model are: by with the inner ring face of the dead axle body of rotating shaft attachment portion a pair of keyway is set in coupling, make rotating shaft force balance when connecting, improve its stability, prolong its working life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is right elevation of the present utility model.
Wherein: 1, connect body, 2, the dead axle body, 3, fixing girth sheets, 21, keyway, 31, bolt hole.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of reel coupling shown in Figure 2 such as Fig. 1, comprise the coupling body, the coupling body comprises connection body 1 and dead axle body 2, be provided with the fixedly girth sheets 3 that is connected for the reel end face on the outer ring face of dead axle body 2, connect body 1 and dead axle body 2 and have the endoporus that communicates, be provided with a pair of keyway 21 on the inner ring face of dead axle body 2, connect body 1, dead axle body 2 and fixedly girth sheets 3 be structure as a whole, fixedly be provided with bolt hole 31 on the girth sheets 3.
By in coupling, with the inner ring face of the dead axle body 2 of rotating shaft attachment portion a pair of keyway 21 being set, make rotating shaft force balance when connecting, improve its stability, prolong its working life.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
