The utility model has the advantages of: 1, the concentricity of whole rotor parts can have been guaranteed well in the requirement that reduces the machining precision, 2, the degree of difficulty of assembly, dismantlement has been reduced, 3, reduced cost of maintenance, work load has significantly reduced.
Description
Technical field
The utility model relates to pump, particularly relates to a kind of easily mounting or dismounting jacket cylinder coupling structure.
Background technique
Refer to Fig. 1, shown is a kind of sleeve coupling structure, is made up of a box coupling, a shaft coupling and a snap ring.With 6 ~ 8 screw Joining clasps and box coupling during installation, in running, bear rotor weight and axial force by shaft coupling, snap ring and screw.Refer to Fig. 2, shown is another kind of sleeve coupling structure structure, is made up of a box coupling, two pressing plates and two snap rings.Connect pressing plate and box coupling with 6 ~ 8 screws during installation, in running, bear rotor weight and axial force by snap ring and screw.In order to transmitting torque and the coaxality ensureing diaxon, it is long that box coupling does, and adds long term submersion in water work, produces the reasons such as corrosion, causes the dismounting of box coupling, assembles quite difficulty again.Many times have to adopt destroy method in maintenance process, namely adopt the method such as gas cutting, hammering to destroy box coupling, remove part like this and generally all can not continue to use.Even sometimes, there is the situation of " killing " in box coupling and axle, axle can only be cut off like this and just can take maintenance apart.Therefore maintenance cost strengthens, and workload is also large, and the cycle is long, labor intensity is high, and has potential danger.In addition, in order to ensure concentricity and the rigidity of whole rotor, box coupling and axle adopt the cooperation of H8/h7, and roughness is at below Ra1.6.More difficult during such assembling, box coupling tolerance changed greatly afterwards, and rotor concentricity can not ensure well, and vibration aggravation during operation, rubber bush bearing damages very fast, and service cycle is shorter, and seriously jeopardizes the safe and stable operation of pump.
Model utility content
The purpose of this utility model is to overcome the problem not easily installed and removed in prior art, provides a kind of novel sleeve coupling structure.
In order to realize this purpose, the technical solution of the utility model is as follows: a kind of easily mounting or dismounting jacket cylinder coupling structure, include, first axle, the second axle, box coupling, the first pressing plate and the second pressing plate, wherein, described first axle extends in the first end of described box coupling, and described second axle extends in the second end of described box coupling; Described first pressing plate is fixed on described first axle and adjacent to described box coupling, described first pressing plate is combined with described box coupling by screw; Described second pressing plate is fixed on described second axle and adjacent to the second end of described box coupling, described second pressing plate is combined with described box coupling by screw; Again, the fitting surface of described first axle and described box coupling is the first conical surface, and the fitting surface of described second axle and described box coupling is the second conical surface, the cone angle of described first conical surface and equal and opposite in direction relative with the cone angle of described second conical surface.
As a kind of preferred version of easy mounting or dismounting jacket cylinder coupling structure, the cone angle of described first conical surface controls at 4-6 °.
As a kind of preferred version of easy mounting or dismounting jacket cylinder coupling structure, described first axle is formed with the first groove, and described first groove is in order to hold described first pressing plate; Described second axle is formed with the second groove, and described second groove is in order to hold described second pressing plate; Again, between the first end of described first pressing plate and described box coupling, there is the first gap, between the second end of described second pressing plate and described box coupling, have the second gap.
As a kind of preferred version of easy mounting or dismounting jacket cylinder coupling structure, described first axle is connected by the first key with between described box coupling, and described second axle is connected by the second key with described box coupling.
Compared with prior art, the utility model has the advantage of: (1) can ensure that the concentricity of whole rotor part well while the requirement reducing machining accuracy; (2) difficulty of assembling, dismounting is decreased; (3) reduce maintenance cost, greatly reduce workload.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of the utility model one embodiment.
Fig. 3 is the structural representation of another embodiment of the utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail below by concrete mode of execution.
Refer to Fig. 3, shown in figure is a kind of easily mounting or dismounting jacket cylinder coupling structure, forms primarily of the first axle 1, second axle 2, box coupling 3, first pressing plate 4 and the second pressing plate 5.
Wherein, described first axle 1 extends in the first end of described box coupling 3, and described second axle 2 extends in the second end of described box coupling 3.Described first pressing plate 4 to be fixed on described first axle 1 and adjacent to described box coupling 3.Described first pressing plate 4 is combined with described box coupling 3 by screw.Described second pressing plate 5 is fixed on described second axle 2 and adjacent to the second end of described box coupling 3, described second pressing plate 5 is combined with described box coupling 3 by screw.Again, described first axle 1 is the first conical surface with the fitting surface of described box coupling 3, and described second axle 2 is the second conical surface with the fitting surface of described box coupling 3, the cone angle of described first conical surface and equal and opposite in direction relative with the cone angle of described second conical surface.In the present embodiment, the cone angle of described first conical surface 5 °.Described first axle 1 is formed with the first groove, and described first groove is in order to hold described first pressing plate 4.Described second axle 2 is formed with the second groove, and described second groove is in order to hold described second pressing plate 5.
Again, between the first end of described first pressing plate 4 and described box coupling 3, there is the first gap, between the second end of described second pressing plate 5 and described box coupling 3, have the second gap.Described first axle 1 is connected by the first key with between described box coupling 3, and described second axle 2 is connected by the second key with described box coupling 3.
During operation, process according to said structure.Use cone gauge inspection after processing, as long as taper-face contact area is greater than 70%, the concentricity of whole rotor part can be ensured well.In addition, bevel precision need not be too high, and surface roughness reaches Ra6.3.Through calculating thickness of compressive plate reasonable in design, select suitable screw specification or quantity just can meet requirement of strength and operational reliability.Only upper and lower two axles need be inserted box coupling 3 during installation, with screw, pressing plate and box coupling 3 be compressed.Only loose box coupling 3 need be struck gently during dismounting.
Below only have expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
