The utility model relates to the technical field of centrifugal pumps, in particular to a bearing body structure for a pump. The bearing body structure comprises a pump shaft, a bearing, a bearing body, a bearing pressing cover, a shaft sleeve nut, a bearing spacer sleeve and a seal ring, and is characterized in that a thread section is arranged on an inner side of a bearing installation face of the bearing shaft, upper threads of the thread section are connected with a bearing disassembling sleeve, the bearing pressing cover is sleeved on the bearing disassembling sleeve which contacts with the bearing through the bearing spacer sleeve, one end of an inner hole in the bearing disassembling sleeve is provided with a thread hole, the other end of the inner hole in the bearing disassembling sleeve is provided with a shaft hole, the thread hole is communicated with the shaft hole, and the bearing disassembling sleeve, corresponding to the outer end of the shaft hole, is provided with a disassembling notch. Due to the structure, the bearing body structure has the advantages of being simple in structure, convenient to operate, time-saving, and labor-saving, meeting precision requirements of the bearing, and avoiding damage, and the like.
Description
Technical field
The utility model relates to the centrifugal pump technical field, specifically a kind of convenient disassembly, time saving and energy saving bearing in pump body structure.
Background technique
At present, the bearing body structure at traditional centrifugal pump pump shaft two ends is by bearing, bearing support, bearing gland, sleeve nut, axle sleeve interstage sleeve and seal ring form, the pump shaft two ends are fixed with respectively bearing, bearing is fixedly connected with the pump housing through bearing support, bearing outside diameter is inner inconsistent with bearing gland, bearing bore diameter outer end and the floor clip that is fixed on the pump shaft end, sleeve nut is inconsistent, inner inconsistent with the bearing interstage sleeve that is fixed on the pump shaft, to guarantee the normal operation of pump shaft, bearing gland is fixedly connected with bearing support through seal ring, the bearing gland side is provided with oil hole, be beneficial to lubricating bearings, bearing support is provided with air relief cock, its deficiency is: when changing the inner body of the pump housing, need first with bearing support, bearing disassembles the part that could change in the pump housing one by one, and interference fit is all adopted in the installation of common bearing and pump shaft, in unloading process, need to strike, beat, or use professional tool bearing could be taken out from pump shaft, waste time and energy like this, if careless manipulation is easy to damage bearing.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, time saving and energy saving, guarantee the bearing accuracy requirement, avoid the bearing in pump body structure that damages.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of bearing in pump body structure, comprise pump shaft, bearing, bearing support, bearing gland, sleeve nut, axle sleeve interstage sleeve and seal ring, the bearing attachment face inboard that it is characterized in that pump shaft is provided with thread section, the bearing removal cover has been threaded on the thread section, bearing gland is enclosed within bearing removal and puts, the bearing removal cover is inconsistent through bearing interstage sleeve and bearing, described bearing removal cover endoporus one end is provided with tapped hole, the other end is provided with axis hole, tapped hole and axis hole are connected, bearing removal cover corresponding shaft outer end of hole is provided with the dismounting breach, is beneficial to hook the fixing rotation of dismounting breach with Hook wrench, by swivel bearing dismounting cover, bearing housing ejects bearing vertically, guarantee the required precision of bearing, avoided the damage of bearing, made things convenient for dismounting.
The utility model is owing to adopt said structure, has required precision simple in structure, easy to operate, time saving and energy saving, as to guarantee bearing, avoids the advantage such as damage.
Description of drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Reference character: bearing support 1, pump shaft 2, sleeve nut 3, floor clip 4, air relief cock 5, oil hole 6, bearing 7, bearing removal cover 8, bearing interstage sleeve 9, bearing gland 10, seal ring 11, bearing attachment face 12, thread section 13.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in drawings, a kind of bearing in pump body structure, comprise pump shaft 2, bearing 7, bearing support 1, bearing gland 10, sleeve nut 3, axle sleeve interstage sleeve 9 and seal ring 11, pump shaft 2 two ends are fixed with respectively bearing 7, bearing 7 is fixedly connected with the pump housing through bearing support 1, bearing 7 external diameters are inner inconsistent with bearing gland 10, bearing 7 internal diameter outer ends and the floor clip 4 that is fixed on pump shaft 2 ends, sleeve nut 3 is inconsistent, inner inconsistent with the bearing interstage sleeve 9 that is fixed on the pump shaft 2, to guarantee the normal operation of pump shaft 2, bearing gland 10 is fixedly connected with bearing support 1 through seal ring 11, bearing gland 10 sides are provided with oil hole 6, be beneficial to lubricating bearings, bearing support 1 is provided with air relief cock 5, bearing attachment face 12 inboards that it is characterized in that pump shaft 2 are provided with thread section 13, the bearing removal that has been threaded on the thread section 13 cover 8, bearing gland 10 is enclosed within on the bearing removal cover 8, bearing removal cover 8 is inconsistent through bearing interstage sleeve 9 and bearing 7, described bearing removal overlaps 8 endoporus, one end and is provided with tapped hole, the other end is provided with axis hole, tapped hole and axis hole are connected, bearing removal overlaps 8 corresponding shaft outer end of hole and is provided with the dismounting breach, be beneficial to hook the fixing rotation of dismounting breach with Hook wrench, by swivel bearing dismounting cover 8, bearing removal cover 8 ejects bearing 7 vertically, has guaranteed the required precision of bearing 7, avoid the damage of bearing 7, made things convenient for dismounting.
When the utility model is dismantled bearing 7 at needs replacing pump inner body, because bearing removal cover 8 is connected with pump shaft 2 by screw thread, hooking the dismounting breach that bearing removal overlaps 8 one ends with Hook wrench rotates centered by the pump shaft axis, bearing removal cover 8 is ejected bearing 7, reached purpose for convenience detach, also avoided the damage bearing, simultaneously, also saved the operating time.
The utility model is owing to adopt said structure, has required precision simple in structure, easy to operate, time saving and energy saving, as to guarantee bearing, avoids the advantage such as damage.
