Abstract
The utility model relates to a kind of coupling device, the axle sleeve comprising forked axle and match with forked axle, and described forked axle is threaded with axle sleeve; There is tapped hole the end that described axle sleeve matches with forked axle, and the end of described forked axle is stretched in the mode of Spielpassung and remains in tapped hole; Solve coupling shaft normally single piece, the problem of corrupted detachable maintaining inconvenience; Detachable maintaining is convenient, torsional property is good.
Description
Technical field
The utility model belongs to metering pump field, is specifically related to a kind of coupling device.
Background technique
The coupling shaft of current connection spinning pump and motors of metering pumps adopts 42CrMo material, and this material Property comparison is crisp, application be not very extensively, price is slightly high, adding that material toughness is not fine, often can't stand that corresponding moment of torsion usually ruptures because holding in joint; Coupling shaft is single piece normally, the inconvenience of corrupted detachable maintaining.
Model utility content
The purpose of this utility model is to provide the coupling device that a kind of detachable maintaining is convenient, torsional property is good.
The technological scheme realizing the utility model object is: a kind of coupling device, the axle sleeve comprising forked axle and match with forked axle, and described forked axle is threaded with axle sleeve; There is tapped hole the end that described axle sleeve matches with forked axle, and the end of described forked axle is stretched in the mode of Spielpassung and remains in tapped hole.
The universal-joint place of preferred described forked axle is provided with stiffening rib.
Preferred described forked axle and axle sleeve are all No. 45 steel through surface blackening process.
Shi great footpath, the end 48mm of preferred described forked axle, the common v thread of pitch 2mm, the outside diameter of described axle sleeve is 75mm, and diameter of bore is 45mm.
The utility model has positive effect: the single piece of coupling shaft be divided into by after the forked axle be threaded and axle sleeve two parts, even if appear corrupted, workman's disassembly and assembly are also very convenient again, can save maintenance cost.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is the left sectional view of forked axle;
Fig. 2 is the main sectional view of axle sleeve;
1 is forked axle, and 2 is axle sleeves, and 3 is tapped holes, and 4 is stiffening ribs
Embodiment
See Fig. 1 and Fig. 2, the utility model has a kind of coupling device, the axle sleeve 2 comprising forked axle 1 and match with forked axle 1, and described forked axle 1 is threaded with axle sleeve 2; There is tapped hole 3 end that described axle sleeve 2 matches with forked axle 1, and the end of described forked axle 1 is stretched in the mode of Spielpassung and remains in tapped hole 3.
The single piece of coupling shaft be divided into by after the forked axle 1 be threaded and axle sleeve 2 two-part, even if appear corrupted, workman's disassembly and assembly are also very convenient again, can save maintenance cost.
The universal-joint place of further described forked axle 1 is provided with stiffening rib 4, and intensity obtains better lifting.
Further described forked axle 1 and axle sleeve 2 are all No. 45 steel through surface blackening process, and the Toughness Ratio of No. 45 steel is better, and the moment of torsion that should bear mutually is comparatively large, not easy-rupturing.
Shi great footpath, the end 48mm of further described forked axle 1, the common v thread of pitch 2mm, the outside diameter of described axle sleeve 2 is 75mm, and diameter of bore is 45mm.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
