Abstract
The utility model discloses a kind of coupling, comprise axle sleeve, in described axle sleeve, be provided with keyway, one end of described axle sleeve is provided with land, the other end of described axle sleeve is connected with axle, described land is provided with at least three locating columns and at least three positioning holes, and described locating column surface is provided with multiple fins, is provided with and many described fins many grooves one to one in described positioning hole.The utility model can link together two axles by two this same coupling, by axle sleeve, axle is carried out to hoop location, on axle sleeve, be provided with land, on land, be provided with locating column with fin and the positioning hole with groove, structure stability after connection is better, easy for installation, less demanding to installation precision, reduce the cost of operation and maintenance.
Description
Technical field
The utility model relates to a kind of mechanical connecting device, relates in particular to a kind of constitutionally stable 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, coupling is made up of two halves, connect with driving shaft and driven shaft respectively, traditional coupling is often too high to required precision, install inconvenient, structural stability performance is general, has increased operation and maintenance cost.
Model utility content
The purpose of this utility model is just to provide in order to address the above problem a kind of constitutionally stable coupling.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of coupling, comprise axle sleeve, in described axle sleeve, be provided with keyway, one end of described axle sleeve is provided with land, the other end of described axle sleeve is connected with axle, described land is provided with at least three locating columns and at least three positioning holes, and described locating column surface is provided with multiple fins, is provided with and many described fins many grooves one to one in described positioning hole.
Further, between described axle and axle sleeve for key is connected.
As preferably, described keyway is groove.
As preferably, the connecting end of described locating column and the connecting end of described positioning hole are provided with chamfering.
The beneficial effects of the utility model are:
The utility model can link together two axles by two this same coupling, by axle sleeve, axle is carried out to hoop location, on axle sleeve, be provided with land, on land, be provided with locating column with fin and the positioning hole with groove, structure stability after connection is better, easy for installation, less demanding to installation precision, reduce the cost of operation and maintenance.
Brief description of the drawings
Fig. 1 is the structural representation of coupling described in the utility model;
Fig. 2 be in Fig. 1 A to sectional structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model comprises axle sleeve 3, in axle sleeve 3, be provided with keyway 2, one end of axle sleeve 3 is provided with land 4, the other end of axle sleeve 3 is connected with axle, between axle and axle sleeve 3 for key is connected, keyway 2 is groove, conveniently knock in positioning key, land 4 is provided with at least three locating columns 5 and at least three positioning holes 1, locating column 5 surfaces are provided with multiple fins 6, are provided with and many fins 6 many grooves 7 one to one in positioning hole 1, and the connecting end of the connecting end of locating column 5 and positioning hole 1 is provided with chamfering.
Coupling described in the utility model, two axles can be linked together by two this same coupling, by axle sleeve 3, axle is carried out to hoop location, on axle sleeve 3, be provided with land 4, on land 4, be provided with locating column with fin 65 and the positioning hole 1 with groove 7, in the time connecting, locating column 5 inserts positioning hole 1, owing to being provided with chamfering, it is easier that locating column 5 coordinates with positioning hole 1, and fin 6 embeds groove 7, structure stability after connection is better, and easy for installation, less demanding to installation precision, reduce the cost of operation and maintenance.
In the time of processing the utility model, land 4 can be welded on axle sleeve 3, also can be taking cylinder as prototype, on cylinder, first process land 4, being close to the place reprocessing axle sleeve 3 of land 4, then offer through hole, in through hole, offer keyway 2, by contrast, the latter's structure is more reliable and stable, but manufacture cost is higher.
