Description
Technical Field
The utility model relates to a magnetic drive pump shaft coupling especially relates to a magnetic drive pump shaft coupling connection structure.
Background
The traditional magnetic pump is generally connected with an external magnetic steel through interference fit or key slot fit to transmit torque, the interference fit connection mode is easy to lose efficacy when the temperature fluctuation is large, and meanwhile, a cold source or a heat source is needed in the dismounting process, so that the operation and maintenance are inconvenient; the key and keyway fit mode, through key transmission moment of torsion, the radial rotation of restriction simultaneously, through radial screw restriction axial displacement, because axle footpath and axle intensity restriction, the moment of torsion of key transmission are limited, if need increase the moment of torsion, need lengthen axle and key length, the magnetic drive pump is when changing the operating mode operation, the fluctuation of moment of torsion is big, the key is crowded brokenly or cut short easily, cause the hookup to lose efficacy, limit screw can loosen easily at the high-speed rotatory in-process for a long time simultaneously, can't play the effect effectively, lead to equipment performance to descend or damage equipment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a magnetic drive pump shaft coupling connection structure replaces original axial keyway, this connection structure, and structural strength is high, and the transmission moment of torsion is big, easy dismounting, applicable variable operating mode operation and the big moment of torsion transmission in magnetic drive pump.
The utility model discloses a magnetic drive pump shaft coupling connection structure, which comprises a rotating shaft and a shaft coupling hub, wherein the rotating shaft connection end is provided with a convex part; the connecting end of the coupling hub and the rotating shaft is provided with a groove part which is matched with the shape and the size of the convex part; the protruding portion and the groove portion are fixedly connected through a connecting piece.
A boss is processed at the center of the connecting end of the rotating shaft, a groove is processed at the center of the hub of the coupling, the boss is a cuboid boss, and the groove is a cuboid groove.
Preferably, the connecting piece is a screw, one end of the screw penetrates through the groove part, and the other end of the screw is in threaded connection with the protruding part.
