Stirring a type mechanical seal main feature is: characteristics such as rotating speed is low, and the diameter of axle is big, and the driving torque that sealing needs is bigger; Locking device is to stir the device that type mechanical seal must be used, and locking device is used for the moment of torsion of passing shaft to axle sleeve, drives sealed rotational; The locking device that stirs sealing usefulness is varied, and is different according to actual conditions, selects locking mode also different; More used locking device dismounting inconvenience, reliability is low.
The model utility content
The purpose of the utility model is to overcome above-mentioned not enough problem, and a kind of locking mechanism that stirs sealing usefulness is provided.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of locking mechanism that stirs sealing usefulness; Comprise lock sleeve, snap ring, driving ring, distinguish ring, bolt one, bolt two, nut one, nut two, nut three; Said lock sleeve one end is installed between axle sleeve and the axle; The exterior edge face of the said lock sleeve the other end is provided with tapped hole and tapped through hole, and said bolt one is installed on the tapped through hole and withstands on the axle sleeve annex, and said driving ring is installed on the axle through the snap ring of hatch frame; Said driving ring exterior edge face is equipped with the distinguish ring; The tapped hole of the corresponding lock sleeve of said driving ring, distinguish ring is offered unthreaded hole one, unthreaded hole two respectively, and said bolt two passes unthreaded hole two, unthreaded hole one is installed in the tapped hole of lock sleeve, and said nut one, nut two, nut three are installed on the bolt two; Wherein nut one is positioned at the exterior edge face of lock sleeve, and nut two is positioned at the interior edge face of driving ring, the exterior edge face that nut three is positioned at the distinguish ring.
Said lock sleeve is installed in the end distinguish opening in the axle sleeve and is wedge shape.
Said lock sleeve adopts the Martensitic Stain Less Steel metallic material.
The characteristics of the utility model are: simple in structure, and easy accessibility, time saving and energy saving, and operational safety is high.
