Abstract
The invention discloses an upright column guide type shaft coupling. The upright column guide type shaft coupling comprises a connecting shaft, wherein a shaft hole is formed on the connecting shaft; a key groove is formed on the inner wall of the shaft hole; the axial cross sections of two ends of the connecting shaft are of trapezoidal structures, and a shaft sleeve a and a shaft sleeve b are respectively arranged on the axial cross sections; a threaded hole a is formed on the shaft sleeve a, and a threaded hole b is formed on the shaft sleeve b corresponding to the threaded hole a; bolts pass through the threaded hole a and the threaded hole b to respectively fasten the shaft sleeve a and the shaft sleeve b at the two ends of the connecting shaft; and guide columns are arranged between the shaft sleeve a and the shaft sleeve b. The upright column guide type shaft coupling is simple in structure and easy to implement, and the guide columns are additionally arranged between the shaft sleeve a and the shaft sleeve b, so that the upright column guide type shaft coupling is convenient to assembly, the stability of the entire shaft coupling is enhanced due to the triangular arrangement of the guide columns, and economical and practical effects are achieved.
Description
Technical field
The present invention relates to a kind of coupling, relate in particular to a kind of guide pillar formula 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 when assembling, and the tapped hole correspondence at axle sleeve two ends is cumbersome, causes assembling inconvenience, and after the coupling assembling, less stable.
Summary of the invention
The objective of the invention is to provides a kind of guide pillar formula coupling to the problems referred to above, and it has simple in structure, is easy to realize, the characteristics of easy to assembly and good stability.
The objective of the invention is to realize through following technological scheme:
A kind of guide pillar formula coupling comprises coupling shaft, and said coupling shaft has axis hole; Have keyway on the inwall of said axis hole, the axial cross section of end, coupling shaft both sides is a trapezium structure, and is respectively arranged with axle sleeve a and axle sleeve b; Have tapped hole a on the said axle sleeve a; The position that said axle sleeve b goes up corresponding tapped hole a has tapped hole b, and bolt passes said tapped hole a, tapped hole b axle sleeve a, axle sleeve b are anchored on the two ends of coupling shaft respectively, and is provided with guide pillar between the axle sleeve a, axle sleeve b.
Further, said tapped hole a, tapped hole b are 6, are distributed in respectively on axle sleeve a, the axle sleeve b.
Further, said bolt is a hex head bolt.
Further, said guide pillar is arranged in the blind hole of offering on axle sleeve a, the axle sleeve b.
Further, said guide pillar is 3, is equilateral triangle and arranges.
Beneficial effect of the present invention does, said guide pillar formula coupler structure is simple, be easy to realize that it is through between axle sleeve a, axle sleeve b, setting up guide pillar, and is not only easy to assembly, and guide pillar is triangular in shape arranges, and increased the stability of whole coupling, and is economical and practical.

Among the figure:
1, axle sleeve a; 2, guide pillar; 3, axle sleeve b; 4, hex head bolt; 5, coupling shaft.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Please with reference to Fig. 1 and shown in Figure 2, Fig. 1 is the sectional view of guide pillar formula coupling of the present invention; Fig. 2 is the plan view of guide pillar formula coupling of the present invention.In present embodiment, a kind of guide pillar formula coupling comprises coupling shaft; Said coupling shaft has axis hole, has keyway on the inwall of said axis hole, and the axial cross section of end, coupling shaft both sides is a trapezium structure; And be respectively arranged with axle sleeve a and axle sleeve b, and being evenly equipped with 6 tapped hole a on the said axle sleeve a, the position that said axle sleeve b goes up corresponding tapped hole a is evenly equipped with 6 tapped hole b; Hex head bolt passes said tapped hole a, tapped hole b axle sleeve a, axle sleeve b is anchored on the two ends of coupling shaft respectively, is provided with guide pillar between axle sleeve a, the axle sleeve b, and said guide pillar is 3; Be positive dihedral and arrange, be arranged in the blind hole of offering on axle sleeve a, the axle sleeve b.
During assembling, axle sleeve a is sheathed on the end of coupling shaft after, be flat on the table top, the end of axle sleeve a is by mesa supports; The other end can block axle sleeve a and move axially, at this moment because the axial cross section of coupling shaft end is a trapezium structure; Guide pillar is installed in the blind hole on the axle sleeve a,, is installed on the other end of coupling shaft again with the corresponding guide pillar of axle sleeve b position; And axle sleeve a, axle sleeve b are anchored on the two ends of coupling shaft with hex head bolt, and promptly accomplished the assembling of coupling, convenient and reliable.
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.
