In order to solve the fixing and locking problem of pump shaft and axle sleeve, in existing vertical water pump, shrink-on mode between pump shaft and axle sleeve, is usually adopted to be connected and fixed, namely by adopting interference fit to make axially to be set with between pump shaft and axle sleeve again to Zhou Tao Jia Re ﹑.But water pump, through long-time running, will inevitably cause the wearing and tearing of axle sleeve.When axle sleeve because of wear and tear excessive cannot continue use and need change time, axle sleeve cannot disassemble from pump shaft by user easily, at present when head it off, need to transport the pump shaft be under disjunctor shape body and axle sleeve back factory, and utilize the mode of turning by the removing of the axle sleeve of wearing and tearing, adopt shrink-on mode to reinstall new axle sleeve again, this axle sleeve substitute mode wastes time and energy, and has also stopped over the normal use of water pump.
Model utility content
In order to solve the fixing and locking problem of above-mentioned pump shaft and axle sleeve, it is simple that the purpose of this utility model is to provide a kind of structure, mounts and dismounts axle sleeve fixation assembly easily.
In order to achieve the above object, the utility model have employed following technological scheme:
A kind of axle sleeve fixation assembly, has such feature, comprising: rotating shaft; Axially be sleeved on the axle sleeve in rotating shaft; The gib head key of radial connection rotating shaft and axle sleeve; And ring is located at the back-up ring for axially locating axle sleeve in rotating shaft.
Further, in the axle sleeve fixation assembly that the utility model provides, such feature can also be had: rotating shaft is multidiameter shaft.
Further, in the axle sleeve fixation assembly that the utility model provides, such feature can also be had: rotating shaft is provided with the circlip groove of engaging back-up ring in the shaft part part of sheathed axle sleeve; One end of axle sleeve and the step surface of multidiameter shaft abut against, and the other end and the back-up ring of axle sleeve abut against.
Further, in the axle sleeve fixation assembly that the utility model provides, such feature can also be had: rotating shaft is provided with the keyway of chimeric gib head key at the position near circlip groove.
Further, in the axle sleeve fixation assembly that the utility model provides, such feature can also be had: axle sleeve is being provided with the breach of chimeric gib head key with one end that back-up ring contacts.
The good effect that the utility model has on the basis of the above is:
The axle sleeve fixation assembly that the utility model provides, by arranging gib head key between rotating shaft and axle sleeve, reaches rotating shaft to the effect of axle sleeve transmitting torque; And by back-up ring, axially locating is carried out to axle sleeve and gib head key, thus realize the fixing and locking problem between rotating shaft and axle sleeve.When changing axle sleeve, only need take off back-up ring, axially extracting axle sleeve and can realize being separated of rotating shaft and axle sleeve, there is structure simple, dismounting and advantage easy for installation.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of embodiment's Intermediate shaft sleeve fixation assembly of the present utility model.
Fig. 2 is the structural representation of rotating shaft.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
As shown in Figure 1, the axle sleeve fixation assembly that provides of the present embodiment.Comprise: rotating shaft 1, axle sleeve 2, the gib head key 3 of L-type, and annular retaining ring 4.
Axle sleeve 2 is axially sleeved in rotating shaft 1, and the installation and removal conveniently between axle sleeve 2 and rotating shaft, adopt Spielpassung between axle sleeve 2 and rotating shaft 1.The radial connection rotating shaft 1 of gib head key 3 and axle sleeve 2, annular retaining ring 4 ring is located in rotating shaft 1 for axially locating axle sleeve 2.
Concrete, as depicted in figs. 1 and 2, rotating shaft 1 is the integral type multidiameter shaft be made up of the first shaft part 11 ﹑ second shaft part 12 ﹑ the 3rd shaft part 13 ﹑ and the 4th shaft part 14.The diameter of the second shaft part 12 is greater than the diameter of the first shaft part 11 and is less than the diameter of the 3rd shaft part 13.Between second shaft part 12 and the 3rd shaft part 13, there is step surface 131.
In the present embodiment, axle sleeve 2 is sleeved on the second shaft part 12 part, and rotating shaft 1 is provided with the circlip groove 121 of engaging annular retaining ring 4 in the second shaft part 12 part.Concrete, circlip groove 121 is arranged on the circumferential surface of left end in the nearly Fig. 2 of the second shaft part 12.Further, one end (right-hand member namely in Fig. 1) of axle sleeve 2 and the step surface 131 of multidiameter shaft abut against, and the other end (left end namely in Fig. 1) and the annular retaining ring 4 of axle sleeve 2 abut against.
Rotating shaft 1 is provided with the keyway 122 of chimeric gib head key 3 at the position near circlip groove 121, correspondingly, axle sleeve 2 is being provided with the rectangular indentation 21 of chimeric gib head key 3 with one end that annular retaining ring 4 contacts (left end namely in Fig. 2), concrete, keyway 122 is fitted together to the flat key part of gib head key 3, and rectangular indentation 21 is fitted together to the eave tile part of gib head key 3.After taking off annular retaining ring 4, when axially extracting axle sleeve, the gib head key 3 be entrenched in rectangular indentation 21 is extracted out automatically in keyway 122, thus facilitates being separated of rotating shaft 1 and axle sleeve 2.
