Abstract
The utility model discloses a connecting shaft structure of a submerged pump. The connecting shaft structure comprises a shaft A, bolts and a shaft B. A shaft sleeve is arranged on an outer ring of a joint of the shaft A and the shaft B, the bolts are arranged on the shaft sleeve, a key A is arranged between the shaft A and the shaft sleeve, a key B is arranged between the shaft B and the shaft sleeve, threaded holes are formed in the connected centers of the shaft A and the shaft B, and the shaft A is connected with the shaft B by a double-end bolt; the bolts are arranged on planes, 180-degree included angles are formed among the key A, the key B and the planes, and the bolts penetrate nuts and the shaft sleeve to compress the shaft A and the shaft B. The connecting shaft structure has the advantages that the connecting shaft structure is convenient to mount; the shaft A is connected with the shaft B by the central threaded holes, accordingly, the connecting shaft structure is good in alignment property, the coaxiality between the two shafts can be effectively guaranteed, and loud noise can be prevented; the connecting shaft structure can run safely and reliably, the service lives of the pump shafts can be prolonged, the production cost can be reduced, and the connecting shaft structure has excellent economic and social benefits when popularized and applied.
Description
Technical field
The utility model belongs to centrifugal pump technical field, particularly a kind of Under Water Pumps spindle structure.
Background technique
At present, for insertion depth under liquid, surpass the long shaft submerged pump of 2 meters, the design of single axle is subject to the restriction of part process and mechanical properties, cannot meet usage requirement, much shorter axles must be coupled together by spindle, meet the needs of longer insertion depth.
Application number is the coupling shaft apparatus device that the Chinese patent of CN201020230962.3 discloses a kind of long shaft submerged pump, adapter, connecting sleeve, upper axle, is consisted of.In adapter, be provided with connecting sleeve; In the middle of in the inner chamber of described connecting sleeve, be provided with a minute semi-ring, the epimere of minute semi-ring is inserted with axle, and the hypomere of minute semi-ring is inserted with lower shaft, and is connected and fixed with upper axle, lower shaft respectively through connecting sleeve by bolt.If adopt this patent, as shown in Figure 1, owing to being subject to the impact of the relative position of spindle nose machining accuracy and keyway, when axle A1, axle B7 diaxon key groove centering, often cause the centering of two between centers bad, concentricity is not high, connect unstable, shortened the working life of pump shaft, also can produce a large amount of noises, cannot meet the requirement of Under Water Pumps safe and reliable operation simultaneously.
Summary of the invention
The purpose of this utility model will solve the problems of the technologies described above.
The purpose of this utility model is achieved in that Under Water Pumps spindle structure, comprise axle A, bolt, axle B, the outer ring of axle A and axle B joint is provided with axle sleeve, bolt is arranged on axle sleeve, between axle A and axle sleeve, be provided with key A, between axle B and axle sleeve, be provided with key B, it is characterized in that: described axle A is provided with tapped hole with the center that axle B is connected, and by stud bolt, connects.
Described bolt is arranged in the plane that becomes 180 degree with key A, key B, and bolt is through nut, axle sleeve compression axis A, axle B.
The utility model is easy for installation, tapped hole by center connects, centering is good, can well guarantee the coaxality of two between centers, can not produce a large amount of noises, safe and reliable to operation, extended working life of pump shaft, reduced cost of production, applied and there is good economic and social benefit.
Accompanying drawing explanation
Fig. 1 is the Under Water Pumps spindle structure structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
In figure: 1. axle A; 2. axle sleeve; 3, key A; 4. minute semi-ring; 5. bolt; 6. key B; 7. axle B; 8. stud bolt.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model:
Under Water Pumps spindle structure, comprise axle A1, bolt 5, axle B7, the outer ring of axle A1 and axle B7 joint is provided with axle sleeve 2, bolt 5 is arranged on axle sleeve 2, between axle A1 and axle sleeve 2, be provided with key A3, between axle B7 and axle sleeve 2, be provided with key B6, described axle A1 is provided with tapped hole with the center that axle B7 is connected, and by stud bolt 8, connects; Described bolt 5 is arranged in the plane that becomes 180 degree with key A3, key B6, and bolt 5 is through nut, axle sleeve 2 compression axis A1, axle B7.
