Abstract
The utility model discloses an impeller axial positioning cover, the epaxial no shaft shoulder, impeller left -right control wantonly when the installation, after having confirmed suitable position, the position sleeve is loaded onto to the left and right both sides of follow symmetry respectively, and the screw on every side position sleeve is equipped with 4 or 6, evenly locates on the position sleeve to screw up with the screw, make and produce the extrusion between position sleeve and wheel hub. The utility model discloses a structural improvement under the prerequisite that need not processing, can be accomplished the impeller shaft and to the adjustment, improve the convenience in the adjustment procedure greatly.
Description
Technical field
The utility model relates to centrifugal pump field, is specifically related to impeller axial positioning sleeve.
Background technique
The main method that general impeller is located on axle is by the shaft shoulder and screw thread location.The side of impeller hub is near the shaft shoulder, and opposite side then completes axially locating by threaded together, and this kind of orientation type is simple, reliable.But need the relative position of adjustment impeller on axle in some cases, impeller can be moved left and right on the basis of original design.If still adopt above-mentioned orientation type, then must process axle, impeller, just can reach the object of adjustment, this brings great inconvenience to axially adjustment.
As shown in Figure 1, the shaft shoulder is close to by suction eye, and right-hand member is by nut location.If want impeller side of turning left to move, then need the turning of shaft shoulder place to fall a part; If want toward moving right, then need at the shaft shoulder and the middle shimming of impeller.Each adjustment all needs to process in a word.
Model utility content
The utility model, by structural improvement, under the prerequisite without the need to processing, can complete impeller shaft to adjustment, substantially increase the convenience in adjustment process.
In order to achieve the above object, the utility model has following technological scheme:
The utility model impeller axial positioning sleeve, described setting sleeve comprises two, and the left side being located at impeller symmetrical respectively and right side, described setting sleeve is fixed on impeller by screw.
Further, described setting sleeve is cirque body, and described toric madial wall extends to form annular projective structure.
Further, the screw on the setting sleeve of every side is provided with 4 or 6, is evenly located on setting sleeve.
Owing to taking above technological scheme, the utility model has the advantage of: location of the present utility model no longer relies on the shaft shoulder and nut, but rely on pressure and frictional force, so do not need to carry out additional processing in the process of adjustment.Axle is laid impeller place and no longer include the shaft shoulder and screw thread, the substitute is two setting sleeves, reach positioning action by the pressure between setting sleeve and axle.

Embodiment
Below implement for illustration of the utility model, but be not used for limiting scope of the present utility model.
As Fig. 2-4, without the shaft shoulder on axle of the present utility model, impeller can adjust left and right arbitrarily when mounted, after determining suitable position, from arranged on left and right sides respectively symmetry load onto setting sleeve, the screw on the setting sleeve of every side is provided with 4 or 6, is evenly located on setting sleeve, and with screw-driving, make to produce extruding between setting sleeve and wheel hub.More preferably, the setting sleeve of the present embodiment is cirque body, and toric madial wall extends to form annular projective structure.After the inclined-plane of setting sleeve is squeezed, axial thrust load and radial component can be produced.Axial thrust load can make impeller have the trend moved axially, but because setting sleeve is the right paired mounting of a first from left, left positioner cover and the axial force that right positioner cover acts on impeller are just in time zero (should be noted that left and right setting sleeve bolt tightening moment should be the same herein, just can make axially is just in time zero with joint efforts) with joint efforts.Radial component then makes setting sleeve produce pressure on axle; In the running of pump, impeller can be subject to responsive to axial force, has the trend of relative movement, as long as but this axial force is not more than the maximum static friction force (maximum static friction force is directly proportional to radial component) of setting sleeve and between centers, impeller just can not slide, thus achieves axially locating.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all mode of executions.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
