Abstract
The utility model discloses an improved sleeve coupling which comprises a connecting shaft I and a connecting shaft II. The improved sleeve coupling is characterized in that: the sleeve coupling comprises a semi-circular cover I, a semi-circular cover II and a sleeve; the semi-circular cover I and the semi-circular cover II are buckled at both ends of the sleeve to form a complete circular sleeve; a segment of sleeve is separated between the semi-circular cover I and the semi-circular cover II; pin shafts respectively penetrate among the semi-circular cover I, the shaft I and the sleeve and among the semi-circular cover II, the shaft II and the sleeve; and the pin shafts are fastened by gaskets, spring gaskets and nuts. In the improved sleeve coupling, the semi-circular cover I and the semi-circular cover II are separated from the sleeve, the shaft I and the shaft II are connected by the two pin shafts, and when the two connecting shafts cannot move in the axial direction, the coupling can be disassembled as the pin shafts are pulled out, so that the disassembly is simple and convenient.
Description
Technical field
The utility model relates to a kind of box coupling, is specifically related to a kind of improved box coupling, belongs to the coupling technical field.
Background technique
The box coupling of present common employing is to utilize sleeve and bearing pin that diaxon is coupled together, and this coupling radial dimension is little, make easily, but shortcoming makes maintenance not too convenient because of being moved axially by coupling shaft when being mounting or dismounting, has also limited its application.
Summary of the invention
The utility model purpose is to overcome above-mentioned deficiency, and a kind of improved box coupling is provided, and is convenient to can not do at coupling shaft shift to mobile occasion and use.
The utility model adopts following technological scheme for realizing above-mentioned purpose:
A kind of improved box coupling; Coupling shaft I and axle II; It is characterized in that: said box coupling comprises semicircle lid I, semicircle lid II and sleeve; Said semicircle lid I, semicircle cover II and are fastened on said sleeve two ends, form a complete circle cover with sleeve, and said semicircle lid I and semicircle are separated with a segment distance between covering between the II; Be installed with a bearing pin respectively between said semicircle lid I, axle I and sleeve and between said semicircle lid II, axle II sleeve, said bearing pin is fastening with packing ring, spring washer and nut.
It is further characterized in that: span changes between 20～40mm between said semicircle lid I and the semicircle lid II.
Further said bearing pin is taper pin or straight pin.
The beneficial effect of the utility model is because sleeve is isolated semicircle lid I and semicircle lid II, with two bearing pins axle I and axle II to be coupled together again; When two coupling shafts can not move axially; Extract bearing pin out, just can coupling be unloaded, make easy removal.

Embodiment
A kind of improved box coupling as shown in Figure 1; Coupling shaft I 5 and axle II 4; Said box coupling comprises semicircle lid I 1, semicircle lid II 2 and sleeve 3, and said semicircle lid I 1, semicircle lid II 2 are fastened on said sleeve 3 two ends, forms a complete circle cover with sleeve 3.Be separated with a segment distance between between said semicircle lid I 1 and the semicircle lid II 2, according to connecting diameter of axle size, its span changes at 20～40mm.When coupling shaft I 5 and axle II 4; Semicircle is covered I 1 to fasten with semicircle lid II 2; After then two bearing pins 6 being passed packing ring 10, semicircle lid I 1 and semicircle lid II 2, axle I 1 and axle II 2 and sleeve 3 respectively; Use packing ring 8, spring washer 9 and nut 7 fastening again, said bearing pin 6 can be a taper pin, also can be straight pin.
During installation, axle I 5 and axle II 4 spans can not cover distance between I 1 and the semicircle lid II 2 less than semicircle.When needs unload box coupling, only need turn on nut 7, extract bearing pin 6 out, semicircle lid I 1 will be taken off with semicircle lid II 2, and sleeve 3 breaks away from axle I 5 and axle II 4 then, and is easy to operate.
