Abstract
The utility model relates to the technical field of mechanical engineering pumps, in particular to a center-adjustable bearing body structure. The center-adjustable bearing body structure is provided with a bearing body and is characterized by being provided with a positioning support, a center-adjusting bolt and a positioning nut; the positioning support is arranged at the outer part of the bearing body; a center-adjusting hole is formed in the lower end of the positioning support; the central line of the center-adjusting hole is vertical to the axis of a rotor; the positioning nut is in threaded connection with the center-adjusting bolt penetrating through the center-adjusting hole to be abutted against the bearing body; the center-adjusting bolt and the positioning support are fixed by the positioning nut. The concentricity of the bearing body is adjusted by screwing up or down the center-adjusting bolt. The Center-adjustable bearing body structure adopting the structure has the advantages of simple structure, convenience in adjusting, protection on the center adjusting of the concentricity of the rotor and the like.
Description
Technical field
The utility model relates to mechanical engineering pump technical field, specifically a kind of bearing body structure of adjusting center of horizontal centrifugal pump.
Background technique
At present, existing large-size horizontal centrifugal pump often finds that in assembly process rotor beats overproofly, analyzes reason and is much because bearing support concentricity guarantees due to bad or each part accumulative total.Its structure diagram is shown in Fig. 1.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of bearing body structure of adjusting center of simple in structure, easy to adjust, protection rotor concentricity is provided.
The utility model solves the technological scheme that its technical problem adopts:
A kind of bearing body structure of adjusting center, be provided with bearing support, it is characterized in that being provided with locating support, aligning bolt and setscrew nut, bearing support outside is provided with locating support, and locating support lower end is provided with aligning hole, aligning centerline hole and rotor axis are perpendicular, the setscrew nut that has been threaded on aligning bolt, aligning bolt is inconsistent through aligning hole and bearing support, and fixes through setscrew nut and locating support, by precession or screw out aligning bolt, adjust bearing support concentricity.
The present invention, owing to adopting said structure, has the advantages such as adjusting center simple in structure, easy to adjust, protection rotor concentricity.
accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present invention.
Reference character: bearing support 1, locating support 2, aligning bolt 3, setscrew nut 4.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of bearing body structure of adjusting center, be provided with bearing support 1, it is characterized in that being provided with locating support 2, aligning bolt 3 and setscrew nut 4, bearing support 1 outside is provided with locating support 2, locating support 2 lower ends are provided with aligning hole, aligning centerline hole and rotor axis are perpendicular, setscrew nut 4 has been threaded on aligning bolt 3, aligning bolt 3 is inconsistent through aligning hole and bearing support 1, and through setscrew nut 4 and locating support 2, fix, by precession or screw out aligning bolt 3, adjust bearing support 1 concentricity.
As shown in Figure 2, the utility model is for large-size horizontal centrifugal pump, during assembling, to the pump shaft inspection of beating, when exceeding pattern requirement, can be by regulating aligning bolt 4 to regulate, regulating method is to unclamp setscrew nut 4, turns aligning bolt 3, until after checking that beating of axle is qualified, setscrew nut 4 is screwed to position, aligning bolt 3 is fixed on locating support 2.
The present invention, owing to adopting said structure, has the advantages such as adjusting center simple in structure, easy to adjust, protection rotor concentricity.
