Abstract
The invention discloses a threaded coupling which comprises a connecting shaft. The connecting shaft is provided with a shaft hole, a key groove is arranged on the inner wall of the shaft hole, and a shaft sleeve a and a shaft sleeve b are sleeved at two ends of the connecting shaft respectively and are connected in a threaded manner. The threaded coupling is simple in structure and easy to implement, and is directly fixedly screwed when in assembly as the shaft sleeves at the two ends of the connecting shaft are connected in the threaded manner. Besides, the threaded coupling is simple to operate and convenient to mount, and is high in concentricity and fine in quality after assembly.
Description
Technical field
The present invention relates to a kind of coupling, relate in particular to a kind of thread type coupling.
Background technique
Coupling is two axles that are used for connecting in the 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 mostly links by means of coupling and working machine, is that the engineering goods axle is the most frequently used coupling member of transmission.
At present, common coupling generally is made up of the axle sleeve at coupling shaft and two ends, has tapped hole on the axle sleeve, and bolt passes the tapped hole of two ends axle sleeve, axle sleeve is anchored on the two ends of coupling shaft; Yet this kind coupling is more loaded down with trivial details when assembling, and after the assembling, concentricity is relatively poor.
Summary of the invention
The objective of the invention is to provides a kind of thread type coupling to the problems referred to above, assembles more loaded down with trivial details problem to solve common coupling, and the relatively poor problem of assembling back concentricity.
The objective of the invention is to realize through following technological scheme:
A kind of thread type coupling comprises coupling shaft, and said coupling shaft has axis hole, has keyway on the inwall of said axis hole, and the coupling shaft two ends are arranged with axle sleeve a and axle sleeve b respectively, and said axle sleeve a is threaded with axle sleeve b.
Further, have circular groove on the said axle sleeve a, be provided with internal thread in the said circular groove, said axle sleeve b is provided with annular lug, and the outer surface of said annular lug is provided with the outside thread that the internal thread with circular groove is complementary.
Further, the external diameter at said coupling shaft two ends is increased by end to centre successively.
Further, all have fixed hole on said axle sleeve a, the axle sleeve b.
Further, the fixed hole on said axle sleeve a, the axle sleeve b is 2, is symmetrically distributed.
Beneficial effect of the present invention does, said thread type coupler structure is simple, is easy to realize, the axle sleeve at coupling shaft two ends is through being threaded, and during assembling, directly screws fixingly, simple to operate, easy for installation, and after the assembling, the concentricity of coupling is high, and quality is good.

Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of thread type coupling of the present invention; In present embodiment, a kind of thread type coupling comprises coupling shaft 6; Said coupling shaft 6 has axis hole, has keyway on the inwall of said axis hole, and the external diameter at coupling shaft 6 two ends is increased by end to centre successively; And its two ends are arranged with axle sleeve a3 and axle sleeve b1 respectively, have circular groove 4 on the said axle sleeve a3, are provided with internal thread in the said circular groove 4; Said axle sleeve b1 is provided with annular lug 5, and the outer surface of said annular lug 5 is provided with the outside thread that the internal thread with circular groove 4 is complementary, and all has fixed hole 2 on said axle sleeve a3, the axle sleeve b1; And the fixed hole 2 on axle sleeve a3, the axle sleeve b1 is 2, is symmetrically distributed.
During assembling, the two ends with axle sleeve a3, axle sleeve b1 are sheathed on coupling shaft 6 respectively screw fixing; The circular groove 4 of axle sleeve a3 is threaded with the annular lug 5 of axle sleeve b1, thereby axle sleeve a3, axle sleeve b1 are anchored on the two ends of coupling shaft 6, and is simple to operate; Easy for installation; And after the assembling, the concentricity of coupling is high, and quality is good.
Above embodiment has just set forth basic principle of the present invention and characteristic; The present invention is not limited by the foregoing description; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various variations and change, and these variations and change all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
