Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of axle sleeve for centrifugal pump, by the axle sleeve structure utilizing lining and sealing ring etc. to form, be highly suitable for the rotating shaft of step structure, there is installation effectiveness height, the advantage that sealing is strong。
Technical scheme is as follows:
A kind of axle sleeve for centrifugal pump, including rotating shaft, the head of described rotating shaft is hierarchic structure, in described rotating shaft sheathed and position have lining, described lining has certain distance apart from the head of described rotating shaft, being provided with implant between the head and described lining of described rotating shaft, the height of described implant is lower than the height of described lining, and described implant is connected with described rotating shaft by securing member；Head in described rotating shaft is peripherally equipped with sealing ring, and described sealing ring and described lining are interlocked。
As preferably, being provided with groove on described lining, described sealing ring is provided with boss, and described boss can with described fit depressions。
As preferably, the height of described implant is the 1/2 of described liner height, and described groove is positioned at the first half of described lining。
Further, described rotating shaft is provided with the key positioning described lining。
Beneficial effect: the present invention is by adopting the rotating shaft of hierarchic structure, can closely cooperate with described sealing ring, by utilizing described sealing ring to be engaged mutually with described lining, and described lining is fixed in described rotating shaft, rotation by described rotating shaft, described lining can be driven to rotate together with described sealing ring, it is possible to reduce gap, it is prevented that dust falls into the outer surface of rotating shaft。
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments。Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention。
Embodiment
A kind of axle sleeve for centrifugal pump, including rotating shaft 1, as shown in Figure 1, the head of described rotating shaft 1 is hierarchic structure, being arranged with lining 2 in described rotating shaft 1, be provided with the key 7 positioning described lining 2 in described rotating shaft 1, described lining 2 has certain distance apart from the head of described rotating shaft 1, its object is to facilitate described lining 2 to be socketed in described rotating shaft 1, improve efficiency of assembling。
Being provided with implant 4 between the head and described lining 2 of described rotating shaft 1, the height of described implant 4 is the 1/2 of described lining 2 height, and described implant 4 is connected with described rotating shaft 1 by securing member；Head in described rotating shaft 1 is peripherally equipped with sealing ring 3, and described sealing ring 3 is interlocked with described lining 2。
With reference to Fig. 1, the length of described sealing ring 3 is exceeded the head of described rotating shaft 1 by the present embodiment, and extend near described lining 2, owing to the diameter at middle part of described rotating shaft 1 is less than the diameter of head, described sealing ring 3 forms a space with head junction in the middle part of described rotating shaft 1, implant 4 it is filled with, by utilizing securing member described implant 4 to be connected with described rotating shaft 1 in this space。
Being provided with groove 5 on described lining 2, described groove 5 is positioned at the first half of described lining 2, and the lower half of described lining 2 contacts with described implant 4, is provided with boss 6 on described sealing ring 3, and described boss 6 can match with described groove 5。
In order to be able to the mentality of designing of the understanding present invention making those skilled in the art apparent, it is described further below in conjunction with assembling process, first implant 4 is fixed in described rotating shaft 1, described sealing ring 3 is inserted in from the afterbody of described rotating shaft 1 to cephalad direction, by utilizing the location of the head hierarchic structure of described implant 4 and described rotating shaft 1, ensure that described sealing ring 3 Fast Installation puts in place, namely can promote efficiency of assembling；Then described lining 2 is penetrated along described rotating shaft 1, by utilizing coordinating of groove 5 and boss 6, it is possible to making described sealing ring 3 be connected as a single entity with described lining 2, it can be positioned by described key 7 simultaneously, it is prevented that obscission occurs。
By above technical scheme, the present embodiment efficiently solves the problem that prior art shaft 1 is easily damaged, rotating shaft 1 by adopting head to be step structure simultaneously, with coordinating of sealing ring 3 and lining 2, while reducing assembly difficulty, improve leakage efficiency, it is even more important that the axle sleeve mentioned by the present embodiment has the extraordinary advantage of sealing effectiveness。
Above-described is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention。
