Description
Technical Field
The utility model relates to a part that water pump was used, a large-scale water pump guide bearing device specifically says so.
Background
When an axial flow pump, a mixed flow pump and a tubular pump of a large-sized pump station are designed and operated, a guide bearing part mainly plays a role in bearing radial force, and for a vertical installation structure, the force acting on the guide bearing is more complicated due to the deviation caused by manufacturing, installation, operation and the like. The existing guide bearing has the defects of complex structure, short service life and inconvenient installation and disassembly. Therefore, the large water pump guide bearing device is very beneficial.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: aiming at the defects of the existing large-scale water pump guide bearing, the large-scale water pump guide bearing device is provided to overcome the defects of the large-scale water pump guide bearing.
The technical scheme of the utility model is realized like this: it includes guide bearing support (4), characterized by: a guide bearing (3) is fixed in a bearing support (4), the guide bearing (3) and the guide bearing support (4) are fixed in the circumferential direction at the upper end through connecting bolts (5) and (6), the axial movement of a bearing bush can be prevented, the lower end is supported through a spigot of the guide bearing support (4), a shaft sleeve (2) is sleeved in the guide bearing (3), and the shaft sleeve 2 is fixed on a main shaft (1) through interference fit. The guide bearing support (4) is fixedly connected with the related parts of the water pump.
The utility model discloses to the macro-pump of built-in guide bearing, this kind of structure is convenient for install and change. When the device is installed, the connecting bolts (5) and (6) are screwed after the device is integrally inserted and combined from the upper part. The utility model discloses simple structure, long service life, installation and dismantlement convenience.
Drawings
FIG. 1 is a schematic view of the structure of the present invention
Detailed Description
The invention will be further described with reference to the accompanying drawings:
as shown in fig. 1, the utility model discloses a guide bearing support (4), bearing support (4) internal fixation has guide bearing (3), guide bearing (3) and guide bearing support (4) are fixed at the circumferencial direction through coupling bolt (5) and (6) in the upper end, can prevent axle bush axial displacement simultaneously, the tang that the lower extreme passes through guide bearing support (4) supports, guide bearing (3) endotheca has axle sleeve (2), axle sleeve 2 fixes on main shaft (1) through interference fit. The guide bearing support (4) is fixedly connected with the related parts of the water pump.
When in maintenance and replacement, only the connecting bolts (5) and (6) need to be loosened, the bush lining and the bearing bush are integrally pulled out from the upper part, the new bearing bush is replaced, the bush lining and the bearing bush are connected through the connecting bolt (5), the combined back bush lining and the bearing bush are integrally inserted from the upper part, and the connecting bolt (6) is screwed down again. The whole structure is simple and reliable, and meanwhile, the installation, maintenance and replacement operation space and procedures of the guide bearing are greatly simplified.
Claims (1)
1.
