Abstract
The utility model discloses a sleeve coupling. The sleeve coupling aims at solving the problem that an existing sleeve coupling is prone to causing rust corrosion between two shafts to result in the consequence that a pump cannot be overhauled, mounted and dismounted or even cannot work normally. The sleeve coupling comprises a sleeve and a connection snap ring which is arranged inside the sleeve and used for connecting a first shaft and a second shaft; sealing structures which are used for preventing liquid from entering the junction surface of the first shaft and the second shaft are arranged both between the first shaft and the sleeve and between the second shaft and the sleeve. The sleeve coupling utilizes the sealing structures between matching surfaces to insulate outside liquid and dirt from entering the inside matching surfaces of the sleeve coupling to achieve rust resistance and anti-corrosion, thereby prolonging the service life of a main shaft rigid connection structure and a main shaft.
Description
Technical field
The utility model relates to field of fluid machinery, is specially a kind of box coupling.
Background technique
The main shaft of existing common vertical pump is connected with the rigid sleeve coupling that is connected to no sealing configuration between the main shaft, as shown in Figure 1, and two main shafts 8,9 axle head stretches in the sleeve 2, and link together by Joining clasp 3, thereby realize connection between two main shafts 8,9.Yet owing to box coupling is immersed in each class I liquid I, and existing structure does not adopt sealing configuration, liquid can infiltrate through the fitting surface of diaxon 8,9, along with the growth of working time, corrosion phenomena can take place in this fitting surface, and when needing maintenance, the secondary mounting or dismounting become very difficult; In addition, because the fine particle in the liquid can be denuded fitting surface in the working environment, reduce quality of fit, thereby cause rotor misalignment, and then the vibration of pump and noise are exceeded standard.
The model utility content
Easily cause the dead and corrosion of rust between the diaxon in order to overcome existing box coupling, thereby cause pump can't overhaul dismounting, even deficiency that can't proper functioning, the utility model aims to provide a kind of box coupling, this box coupling arranges sealing configuration in sleeve, thereby prevent the corrosion of diaxon fitting surface and corrosion, can improve main shaft and be rigidly connected working life of structure and main shaft.
To achieve these goals, the technological scheme that adopts of the utility model is:
A kind of box coupling comprises sleeve, is arranged on the Joining clasp that is used for connecting first and second in the sleeve; Its structural feature is, between described first and the sleeve, be provided with between second and the sleeve and prevent that liquid from entering the sealing configuration of first and second junction plane.
Below be the technological scheme of further improvement of the utility model:
The thrust snap ring that is fixed on described sleeve one end is housed on described second.In order to strengthen sealing effect further, be provided with the shrouding that is sleeved on second between described sleeve and the thrust snap ring; Described sleeve, shrouding and thrust snap ring link together by fastening piece.
The upper end of above-mentioned sleeve is provided with the cover plate that is sleeved on first; Described cover plate and sleeve link together by fastening piece.
Be provided with seal ring between described sleeve and the shrouding, thereby improve sealing effect.
Be provided with the cylndrical surface sealer that is contained on second between described shrouding and the thrust snap ring.
Be provided with seal ring between above-mentioned sleeve and the cover plate.
Be provided with the cylndrical surface sealer that is contained on first between described sleeve and the cover plate.
Compared with prior art, the beneficial effects of the utility model are: the utility model utilizes the liquid in the seal isolation external world between the fitting surface and dirt to enter its inner fitting surface, played the effect of anti-corrosion and corrosion, improved main shaft and be rigidly connected working life of structure and main shaft.The utility model is simple in structure, installation, use, easy to maintenance.
Below in conjunction with drawings and Examples the utility model is further elaborated.
