Abstract
The utility model relates to the technical field of mechanical engineering, in particular to a pump shaft connection device. The pump shaft connection device comprises a pump shaft, a bearing body, a bearing, a bearing lining and a bearing press cover. The outer circle of the bearing is fixedly connected with the bearing body, one end of the outer circle of the bearing abuts against the bearing press cover, and the bearing press cover is fixedly connected with the bearing body. The pump shaft connection device is characterized by being provided with a bearing sleeve, a baffle table is arranged at one end of the bearing sleeve, a bearing installation section is a screw section, the screw section of the pump shaft is in screw connection with the bearing sleeve, an inner circle of the bearing is fixedly connected with the bearing sleeve, one end of the inner circle of the bearing abuts against the bearing lining, and the other end of the inner circle of the bearing abuts against the baffle table. When parts in the pump body are replaced, the bearing is brought out by the bearing sleeve by rotating the bearing sleeve, and disassembly is facilitated. By means of the structure, the pump shaft connection device has the advantages of being reasonable in structure, simple to operate, convenient to disassemble, time-saving, labor-saving, long in service life and the like.
Description
Technical field
The utility model relates to mechanical engineering pump technical field, specifically a kind of pump shaft connection set of conveniently detachable centrifugal pump.
Background technique
As everyone knows, the pump shaft connection set of centrifugal pump comprises bearing, bearing support and bearing gland, the pump shaft two ends are respectively through rolling bearing, bearing support is fixedly connected with the pump housing, bearing and pump shaft interference fit, bearing top circle one end and bearing gland are inconsistent, bearing gland is fixedly connected with bearing support, the bearing sleeve that bearing inner circle one end and pump shaft are provided with is inconsistent, the other end and bearing support are inconsistent, to guarantee the smooth running of pump shaft, its deficiency is: unreasonable structure, dismounting is inconvenient, because bearing and pump shaft interference fit, during part in the replacing pump housing, need first with bearing support, bearing, bearing gland disassembles, and dismounting need to be struck with instrument during bearing, beat or use professional tool it could be disassembled from pump shaft, waste time and energy, misoperation is also damaged bearing easily, causes unnecessary loss.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and the pump shaft connection set of a kind of rational in infrastructure, simple to operate, convenient disassembly, time saving and energy saving, long service life is provided.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of pump shaft connection set, comprise pump shaft, bearing support, bearing, bearing sleeve and bearing gland, bearing top circle is fixedly connected with bearing support, bearing top circle one end and bearing gland are inconsistent, bearing gland is fixedly connected with bearing support, it is characterized in that being provided with bearing housing, bearing housing one end is provided with the gear platform, and the bearing construction section is thread section, the thread section of the pump shaft bearing housing that has been threaded, the bearing inner circle is fixedly connected with bearing housing, and bearing inner circle one end and bearing sleeve are inconsistent, and the other end is inconsistent with the gear platform, when the part in the needs replacing pump housing, by the running shaft bearing sleeve, bearing housing is taken out of bearing, made things convenient for dismounting.
The hand of spiral of the thread section of the pump shaft in the utility model is identical with the sense of rotation of pump shaft, has auto-lock function during with the rotation of assurance pump shaft, has reached the axial position of rigid bearing.
The gear platform outside of bearing housing described in the utility model is provided with the dismounting groove, is beneficial to reach effect simple to operate, time saving and energy saving, convenient disassembly with the fixing rotation of Hook wrench.
The present invention is owing to adopt said structure, has the advantages such as rational in infrastructure, simple to operate, convenient disassembly, time saving and energy saving, long service life.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Reference character: pump shaft 1, bearing support 2, bearing 3, bearing sleeve 4, bearing gland 5, bearing housing 6, gear platform 7, thread section 8, dismounting groove 9.
Embodiment:
The present invention is further described below in conjunction with accompanying drawing:
As shown in drawings, a kind of pump shaft connection set, comprise pump shaft 1, bearing support 2, bearing 3, bearing sleeve 4 and bearing gland 5, bearing 3 cylindricals are fixedly connected with bearing support 2, bearing 3 cylindricals, one end and bearing gland 5 are inconsistent, bearing gland 5 is fixedly connected with bearing support 2, it is characterized in that being provided with bearing housing 6, bearing housing 6 one ends are provided with gear platform 7, bearing 3 construction sections are thread section 8, the thread section 8 of pump shaft 1 bearing housing 6 that has been threaded, and bearing 3 inner circles are fixedly connected with bearing housing 6, bearing 3 inner circles, one end and bearing sleeve 4 are inconsistent, the other end is inconsistent with gear platform 7, when the part in the needs replacing pump housing, by running shaft bearing sleeve 6, bearing housing 6 is taken out of bearing, made things convenient for dismounting.
The hand of spiral of the thread section 8 of the pump shaft 1 in the utility model is identical with the sense of rotation of pump shaft 1, has auto-lock function during with 1 rotation of assurance pump shaft, has reached the axial position of rigid bearing 3.
The utility model hooks dismounting groove 9 with Hook wrench when dismounting, opposite spin bearing housing 6, bearing housing 6 are namely taken bearing 3 out of from pump shaft 1.
The present invention is owing to adopt said structure, has the advantages such as rational in infrastructure, simple to operate, convenient disassembly, time saving and energy saving, long service life.
