Abstract
The utility model relates to a novel fastening structure for a vertical packingless pump shaft, which includes a motor shaft and a pump shaft, wherein the motor shaft is connected with the pump shaft through a key. The novel fastening structure is characterized by further including a tension ring; the inner ring of the tension ring is clung to the pump shaft; mounting holes are uniformly distributed on the end surface of the outer ring of the tension ring; and the tension ring is pressed and fixed through compression screws penetrating the mounting holes. The novel fastening structure for the vertical packingless pump shaft has the advantages of simple structure, capability of radically solving the problem of pump shaft stress, and greatly improved product stability.
Description
Technical field
The utility model relates to vertical unprssurized pump field, particularly a kind of novel fastening structure of vertical unprssurized pump axle that is applied to.
Background technique
What unprssurized pump adopted usually is vertical structure, as illustrated in fig. 1 and 2, and it all is on the motor shaft of standard, to add direct connection axle of cover as pump shaft under normal conditions; With Cock screw pump shaft is fixed on the motor shaft then, should the bearing pump rotor downward axial force and the waterpower axial force of pump of Cock screw this moment also will be born rotation torque partly; Key also bears the part moment of torsion simultaneously; Add mechanical shock in operation process, screw is loosening easily, and stressed effect is bad always.Even if screw is not exclusively loosening, but in bearing the process of moment of torsion also gradually stripped thread cause damaging.So, a kind of novel pump shaft fastening structure is proposed, to improve the stressed not good problem of pump shaft.
Summary of the invention
The utility model is the deficiency to existing technology, has proposed a kind of novel fastening structure of vertical unprssurized pump axle that is applied to.
The utility model is achieved in that the novel fastening structure of vertical unprssurized pump axle; Comprise: motor shaft, pump shaft wherein, are connected through key between motor shaft and the pump shaft; It is characterized in that: also comprise a tensioner circle; The inner ring of this tensioner circle is close to and is located on the pump shaft, is evenly distributed with mounting hole on the cycle surface of tensioner circle, is arranged in by housing screw and realizes in the mounting hole being fixed.
The advantage of the utility model: simple in structure, thoroughly solved the stressed problem of pump shaft.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is that the K-K of Fig. 1 is to sectional view.
Fig. 3 is the structural representation of the utility model.
Fig. 4 is that the K-K of Fig. 2 is to sectional view.
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Embodiment
Among the figure, the novel fastening structure of vertical unprssurized pump axle comprises: motor shaft 1, pump shaft 2; Wherein, Be connected through key between motor shaft and the pump shaft, it is characterized in that: also comprise a tensioner circle, the inner ring 3 of this tensioner circle is close to and is located on the pump shaft; Be evenly distributed with mounting hole 6 on outer ring 4 end faces of tensioner circle, be arranged in by housing screw 5 and realize in the mounting hole being fixed.
Below only expressed the mode of execution of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
The advantage of the utility model: simple in structure, thoroughly solved the stressed problem of pump shaft, improve the stability of product greatly.
