Abstract
The invention discloses a coupler which comprises a tightening sleeve, a shaft hole is formed in the axial direction of the tightening sleeve, a tightening groove is formed in the tightening sleeve, the left end and the right end of the tightening sleeve are connected with a left shaft sleeve and a right shaft sleeve respectively, a connecting sleeve is arranged in the middle position of the tightening sleeve and formed by a left-handed nut at the left end and a right-handed nut at the right end, left-handed outer threads matched with the left-handed nut are arranged at the right end of the left shaft sleeve, and right-handed outer threads matched with the right-handed nut are arranged at the left end of the right shaft sleeve. By arranging the connecting sleeve additionally and by arranging the left-handed outer threads matched with the left-handed nut at the right end of the left shaft sleeve and the right-handed outer threads matched with the right-handed nut at the left end of the right shaft sleeve, connecting is firm, stress is even, possible shaft sleeve loosening caused by shaft rotation is avoided, and the coupler is convenient to detach and install, good in concentricity and large in transmitting torque.
Description
Technical field
The present invention relates to a kind of coupling.
Background technique
Coupling is for connecting two axles in different institutions, makes it the mechanical parts of common rotation with transmitting torque.In the power transmission of high-speed overload, it is the effect of dynamic performance that some coupling also has buffering, vibration damping and raising axle.General power engine is mostly connected by means of coupling and working machine, is that engineering goods axle is the most frequently used coupling member of transmission.
At present, common coupling is generally made up of the axle sleeve at tightening sleeve and two ends, has tapped hole on axle sleeve, and bolt, through the tapped hole of two ends axle sleeve, is anchored on axle sleeve at the two ends of tightening sleeve; But this kind of coupling is more loaded down with trivial details in the time of assembling, and after assembling, concentricity is poor.Chinese patent literature publication number CN202732737 discloses a kind of thread type coupling, the axle sleeve at its two ends is threaded connection, assembling is simple, and after assembling, concentricity is better, it efficiently solves the problems referred to above, but this kind of thread type coupling in use, easily becomes flexible because the rotation of axle causes axle sleeve, and the moment of torsion that the coupling of this kind of structure transmits is less, cannot meet part client's user demand.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of coupling is provided, to solve existing coupling easily because the rotation of axle causes the loosening problem of axle sleeve, and the little problem of existing coupling transmitting torque.
The object of the invention is to be achieved through the following technical solutions:
A kind of coupling, comprise tightening sleeve, described tightening sleeve axially have an axis hole, and on tightening sleeve, have and tighten up groove, left end termination, the right-hand member termination of described tightening sleeve are connected with respectively left axle sleeve, right axle sleeve, and the middle of tightening sleeve is provided with connecting sleeve, described connecting sleeve is made up of the left-handed nut of left end, the right-handed nut of right-hand member, described left axle sleeve right-hand member termination is provided with the sinistral external thread matching with left-handed nut, and described right axle sleeve left end termination is provided with the dextrorotation outside thread matching with right-handed nut.
Preferably, described left-handed nut, right-handed nut are structure as a whole, and adopt integrative-structure, and it is more firm, stressed more even to make to connect, and installation, convenient disassembly.
Preferably, on described right axle sleeve or left axle sleeve, have first and tighten up hole, be convenient to installing/dismounting.
Preferably, the external diameter of the left end termination of described tightening sleeve increases progressively from left to right successively, and the external diameter of the right-hand member termination of tightening sleeve increases progressively from right to left successively, on described left axle sleeve, have the left taper hole matching with the left end termination of tightening sleeve, on described right axle sleeve, have the right taper hole matching with the right-hand member termination of tightening sleeve, further strengthened the join strength of left axle sleeve, right axle sleeve and tightening sleeve.
Preferably, on described connecting sleeve, have second and tighten up hole.
Beneficial effect of the present invention is, described coupling is by setting up connecting sleeve, the two ends of connecting sleeve arrange respectively the left-handed nut matching with the sinistral external thread of left axle sleeve right-hand member termination, the right-handed nut who matches with the dextrorotation outside thread of right axle sleeve left end termination, it is more firm to make to connect, stressed more even, solve because axle rotates the loosening problem of axle sleeve that may bring, and coupling easy accessibility of the present invention, good concentricity, transmitting torque is large, is 1.5 times of original thread type coupling.
Accompanying drawing explanation
