Abstract
The invention discloses a stable bracket bearing positioning structure. The stable bracket bearing positioning structure comprises a long shaft, a bracket bearing, a first bushing, a second bushing and a bracket, wherein the bracket bearing is arranged on the long shaft in a sleeving manner; the gap between the inner surface of the bracket bearing and the long shaft is filled with sealing material; the first bushing is arranged on the long shaft in a sleeving manner and is positioned on one side of the bracket bearing; the second bushing is arranged on the long shaft in a sleeving manner and is positioned on the other side of the bracket bearing; the bracket is butted against the bracket bearing; a matching surface of the bracket bearing and the bracket is an oblique surface. By means of the design of the oblique surface, the requirement on machining accuracy can be reduced and the assembly difficulty can be reduced, and the pump is more stable during operation, so that the vibration and the noise are reduced and the loss caused by radial unbalanced force is greatly reduced.
Description
Technical field
The present invention relates to fluid device, specifically, a kind of steady type bracket bearing position structure.
Background technique
A kind of for preventing the architecture advances of the rotation of sleeve of long-axis vertical type water discharging pump disclosed in Chinese utility model patent CN201902358U, it comprises lifting pipe, support, sleeve pipe, rubber bush bearing, support is offered a tapped hole, and the corresponding section on sleeve pipe offers a matching hole closed with corresponding threaded holes, in tapped hole, connect matching hole by Cock screw.Before pump startup, the impacting force supposing screw is F1, the radial force F2=0 between bracket bearing and support, like this, fitting surface between support and bracket bearing must have higher machining accuracy, otherwise pump can make pump produce larger vibration & noise, time serious at the radial imbalance force that running rotor parts produce, bracket bearing and axle can be caused, the damage of even whole rotor part, brings negative effect to production, and then causes unnecessary economic loss.
Summary of the invention
The present invention seeks to overcome in prior art the problem that there is steadiness difference, propose a kind of steady type bracket bearing position structure.
To achieve these goals, technological scheme of the present invention is achieved in that a kind of steady type bracket bearing position structure, it is characterized in that, comprises,
One major axis;
One bracket bearing, is sheathed on this major axis, is filled with sealing material between the inner face of this bracket bearing and this major axis;
One first sleeve pipe, is sheathed on this major axis, is positioned at the side of this bracket bearing;
One second sleeve pipe, is sheathed on this major axis, is positioned at the opposite side of this bracket bearing; And,
One support, leans with this bracket bearing;
Wherein, the fitting surface of this bracket bearing and this support is inclined-plane.
Compared with prior art, advantage of the present invention: (1) reduces the requirement of machining accuracy; (2) difficulty of assembling is decreased; (3) make pump more firm in the process run, reduce vibration & noise, greatly reduce the loss that radial imbalance force brings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
embodiment
Below in conjunction with drawings and Examples, the present invention is elaborated.
Refer to Fig. 1 and 2, shown in figure is a kind of steady type bracket bearing position structure, forms primarily of major axis 1, bracket bearing 2, sealing material 3,1 first sleeve pipe 4,1 second sleeve pipe 5, support 6, airborne dust pipe 7, hexagon socket cap head screw 8.
Wherein, this bracket bearing 2 is sheathed on this major axis 1, is filled with sealing material 3 between the inner face of this bracket bearing 2 and this major axis 1.
This first sleeve pipe 4 is sheathed on this major axis 1, is positioned at the side of this bracket bearing 2.
This second sleeve pipe 5 is sheathed on this major axis 1, is positioned at the opposite side of this bracket bearing 2.
This support 6 leans with this bracket bearing 2 and this support 6 is inclined-plane with the fitting surface 9 of this bracket bearing 2.
Suppose that the angle of inclined-plane and plane is θ/2, the impacting force of hexagon socket cap head screw is F1, then the active force between bracket bearing and support is
, this force rate F1 itself is much larger, so it is enough to ensure that pump is starting, shutting down and firm between operation process medium-height trestle bearing and support, thus reaches object of the present invention.
Below only have expressed embodiments of the present invention, it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
