Abstract
The utility model discloses a coupling, which comprises a coupling body; the coupling body comprises a cylindrical connecting cylinder; a through hole penetrates through two end surfaces of the coupling body; the inner wall face of the coupling body is provided with a key slot; the bottom end of the coupling body is provided with a first flange plate and a second flange plate; both the first flange plate and the second flange plate are provided with a plurality of connection holes; an arc-shaped concave surface is arranged between the connecting cylinder and the first flange plate; at least one positioning hole is formed in a position, close to the arc-shaped concave surface, of the first flange plate, and penetrates to the bottom of the second flange plate. The coupling has the advantages that the structure is simple, and the assembly is simple and convenient.
Description
Technical field
The utility model relates to field of mechanical technique, is specifically a kind of coupling.
Background technique
Coupling is that two axles (driving shaft and driven shaft) for connecting in different institutions make 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.The coupling of prior art is generally made up of two halves, connects respectively with driving shaft and driven shaft, and often more complicated of the structure of this connector, assembles up cumbersomely, and working life is short.
Summary of the invention
In view of above-mentioned defect, the purpose of this utility model is: a kind of coupling simple in structure and easy to assembly is provided.
Technical solution of the present utility model is: a kind of coupling, comprise coupling main body, described coupling main body comprises a cylindrical connecting cylinder, described coupling main body both ends of the surface are penetrated with a through hole, described coupling main body inner wall face is provided with a keyway, described coupling main body bottom is provided with the first flange plate and the second flange plate, on described the first flange plate and the second flange plate, be equipped with multiple attachment holes, between described connecting cylinder and the first flange plate, be provided with an arc-shaped concave, on described the first flange plate, be provided with at least one positioning hole near arc-shaped concave place, and connect to the second flange plate bottom.
Further, the attachment hole quantity on described the first flange plate is four, and accordingly, the attachment hole quantity on described the second flange plate is also four.
Further, the quantity of described positioning hole is two.
Further, described connecting cylinder is provided with an oilhole.
Application the utility model designed a kind of coupling, its beneficial effect is: simple in structure, coupling main body is structure as a whole, and assembles simple and conveniently, can increase staff's working efficiency, and can also increase the working life of coupling.
