Abstract
The utility model discloses a kind of coupling, comprise coupling housing, the two ends of described coupling shell inner hole are respectively provided with a step hole, two steel axle sleeves respectively with the step hole drive fit at described coupling shell inner hole two ends, it is relative with the radial screw via hole on coupling housing that the hole wall of described axle sleeve is provided with radial screw bore, the hole of described two axle sleeves matches with main shaft and motor shaft respectively, and the material of described coupling housing is polyurethane.The utility model has the advantage of long service life.
Description
Technical field:
The utility model relates to a kind of drive technology, particularly a kind of coupling.
Background technique:
Coupling between the main shaft of drawbench and admission machine and motor shaft, this coupling adopts spring flexible connection structure, is generally namely to rupture the 2-3 month working life of this spring flexible connection structure and scraps, and impact is produced.
Summary of the invention:
The utility model object is to provide a kind of coupling of not easy-rupturing long service life.
Realizing the technical solution of the utility model is, a kind of coupling, comprise coupling housing, it is characterized in that: the two ends of described coupling shell inner hole are respectively provided with a step hole, two steel axle sleeves respectively with the step hole drive fit at described coupling shell inner hole two ends, it is relative with the radial screw via hole on coupling housing that the hole wall of described axle sleeve is provided with radial screw bore, and the hole of described two axle sleeves matches with main shaft and motor shaft respectively, and the material of described coupling housing is polyurethane.
The utility model has the advantage of long service life compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
The utility model has following examples, employing has some strength and good toughness, the polyurethane of good deformation behavior is had to make coupling shell body 1, in the step hole at two steel axle sleeve 2 difference force fit coupling shell inner hole two ends, it is excessively relative with the screw on coupling shell body opening wall that the side face of this axle sleeve is provided with tapped hole, and the tapped hole on the side face of above-mentioned axle sleeve can be established and two or morely to determine as required.
Installation method, first by the step hole of two axle sleeve press-in coupling housings, after making the tapped hole on axle sleeve relative with the hole on coupling housing respectively, then main shaft 4 and motor shaft 3 are injected in axle sleeve hole, with screw, main shaft and motor shaft and coupling housing and axle sleeve are tightened up and can use.This structure is due to the making of coupling housing employing polyurethane, this housing has the function of inhaling moment of torsion, when main shaft and motor decentraction, housing produces the amount that distortion can eliminate decentraction, be difficult to when decentraction amount is excessive eliminate, the utility model is used for the less occasion of decentraction amount, has the advantage of long service life.
