Abstract
The invention relates to the technical field of mechanical engineering pumps, in particular to a pump shaft connecting device. The pump shaft connecting device comprises a pump shaft, a bearing body, a bearing, a bearing sleeve and a bearing gland. 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 gland, and the bearing gland is fixedly connected with the bearing body. The pump shaft connecting device is characterized in that a bearing bush is arranged, a blocking platform is arranged at one end of the bearing bush, a bearing installation section is a threaded section, a threaded section of the pump shaft is in threaded connection with the bearing bush, and the inner circle of the bearing is fixedly connected with the bearing bush. One end of the inner circle of the bearing abuts against the bearing sleeve, and the other end of the inner circle of the bearing abuts against the blocking platform. When parts in a pump body need to be replaced, the bearing can be taken out through the bearing bush by rotating the bearing sleeve, so dismantling is facilitated. By the adoption of the structure, the pump shaft connecting device has the advantages of being reasonable in structure, easy to operate, convenient to dismantle, capable of saving time and labor, long in service life, and the like.
Description
Technical field
The present invention 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, 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, due to bearing and pump shaft interference fit, in the time of the part of changing in the pump housing, need first by bearing support, bearing, bearing gland disassembles, and dismounting need to be struck with instrument when bearing, beat or use professional tool it could be disassembled from pump shaft, waste time and energy, misoperation is also easily damaged bearing, cause unnecessary loss.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, 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 technical solution adopted for the present invention to solve the technical problems 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 gear platform, bearing construction section is thread section, the thread section of the pump shaft bearing housing that has been threaded, bearing inner circle is fixedly connected with bearing housing, bearing inner circle one end and bearing sleeve are inconsistent, the other end is inconsistent with gear platform, when need to change in the pump housing part time, by running shaft bearing sleeve, bearing housing is taken out of bearing, facilitate dismounting.
The hand of spiral of the thread section of the pump shaft in the present invention is identical with the sense of rotation of pump shaft, to guarantee that pump shaft rotation time has auto-lock function, has reached the axial position of rigid bearing.
The gear platform outside of bearing housing described in the present invention is provided with dismounting groove, is beneficial to, with the fixing rotation of Hook wrench, reach effect simple to operate, time saving and energy saving, convenient disassembly.
The present invention is owing to adopting said structure, has the advantages such as rational in infrastructure, simple to operate, convenient disassembly, time saving and energy saving, long service life.
accompanying drawing explanation
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:
Below in conjunction with accompanying drawing, the present invention is further described:
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 cylindrical 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 end 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, bearing 3 inner circles are fixedly connected with bearing housing 6, bearing 3 inner circle one end and bearing sleeve 4 are inconsistent, the other end is inconsistent with gear platform 7, when need to change in the pump housing part time, by running shaft bearing sleeve 6, bearing housing 6 is taken out of bearing, facilitate dismounting.
The hand of spiral of the thread section 8 of the pump shaft 1 in the present invention is identical with the sense of rotation of pump shaft 1, to guarantee that pump shaft 1 has auto-lock function while rotation, has reached the axial position of rigid bearing 3.
The present invention, in the time of dismounting, is hooked and is dismantled groove 9 with Hook wrench, opposite spin bearing housing 6, and bearing housing 6 is taken bearing 3 out of from pump shaft 1.
The present invention is owing to adopting said structure, has the advantages such as rational in infrastructure, simple to operate, convenient disassembly, time saving and energy saving, long service life.
