Description

A kind of vertical sewage pump filler axis and axle sleeve structure

Technical field

The utility model is related to dredge pump field more particularly to a kind of vertical sewage pump filler axis and axle sleeve structures.

Background technology

O-ring slot has been cut in packing sleeve upper end, and lower end is machined with keyway with slotting machine.Such structure is lacked there are following Point：When installing packing sleeve, O-ring is up filled from shaft end with axle sleeve, and in assembling process, O-ring crimp hinders axle sleeve Assembly, and O describes easy incised wound；When slotting machine keyseat, packing sleeve upper end is clamped, often upper end wall thickness is relatively thin, when clamping It is easily deformed, can not ensure the precision of its axis hole, be unfavorable for assembling.

Utility model content

The purpose of this utility model is to provide a kind of vertical sewage pump filler axis and axle sleeve structure.

To achieve the goals above, the technical solution of the utility model is：

A kind of vertical sewage pump filler axis and axle sleeve structure, it includes main shaft and the filler axis being socketed on outside main shaft Set, which is characterized in that the side reduced radius of the main shaft forms the shaft shoulder, and the other side of the main shaft is equipped with impeller, the master Baffle ring, one end fitting shaft shoulder setting of the baffle ring are socketed on axis, the other end of the baffle ring and one end of packing sleeve connect, The inner edge at the packing sleeve end is tilted towards center and extends to form angle groove, and the angle groove is arranged close to baffle ring, the gear Gap between circle and angle groove is equipped with O-ring, and the other end of the packing sleeve forms dowel hole, institute along major axes orientation hollow out It states main shaft to be protruded outward equipped with convex key, the convex key is arranged along major axes orientation, the position of the convex key and the position of dowel hole Cooperation.

Technical solution described in the utility model facilitates O-ring to assemble, ensures in axle sleeve by improving packing sleeve structure Hole precision；O-ring is more easily installed at angle, angle in groove processing.Baffle ring is installed on the shaft shoulder when installation, assembles O-ring afterwards, then Packing sleeve is installed, this way effectively prevents O-ring incised wound.

Specific implementation mode

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally The every other embodiment that field those of ordinary skill is obtained without making creative work, belongs to this practicality Novel protected range.

The utility model provides a kind of vertical sewage pump filler axis and axle sleeve structure, it includes main shaft 1 and socket Packing sleeve 4 outside main shaft 1, which is characterized in that as shown in Figure 1, the side reduced radius of the main shaft 1 forms the shaft shoulder 2, The other side of the main shaft 1 is equipped with impeller 3, and baffle ring 5 is socketed on the main shaft 1, and one end fitting shaft shoulder 2 of the baffle ring 5 is arranged, The other end of the baffle ring 5 is connect with one end of packing sleeve 4.

As depicted in figs. 1 and 2, the inner edge at 4 end of the packing sleeve is tilted towards center and extends to form angle groove 6, described Angle groove 6 is arranged close to baffle ring 5, and the gap tank car between the baffle ring 5 and angle groove 6 assembles, institute at angle convenient for O-ring 7 The other end for stating packing sleeve 4 forms dowel hole 8 along 1 direction hollow out of main shaft, and the main shaft 1 protrudes outward is equipped with convex key 9, institute Convex key 9 is stated along 1 direction of main shaft to be arranged, the stem of the convex key 9 coordinates with dowel hole 8, the tail portion setting of convex key 9 impeller 3 it Between.

As shown in figure 3, the dowel hole 8 uses wire cutting, and it is designed as keyway through-hole, throwing of the dowel hole 8 in horizontal plane Shadow is rectangle, and the section in an axial direction of dowel hole 8 is similarly rectangle, and processing cutting is convenient, and when processing is not required to clamping sleeve outer circle, Inner hole of shaft sleeve is avoided to be caused to deform by stress, to the position of positive keyway when the structure of through-hole is convenient for assembling.

Finally it should be noted that：The above various embodiments is only to illustrate the technical solution of the utility model, rather than limits it System；Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should Understand：It still can be with technical scheme described in the above embodiments is modified, either to which part or whole Technical characteristic carries out equivalent replacement；And these modifications or replacements, this practicality that it does not separate the essence of the corresponding technical solution are new The range of each embodiment technical solution of type.
