Description
Technical Field
The utility model relates to a water pump unit, a lubricated formula non-drive end bearing structure of thin oil specifically says so.
Background
In the mechanical field, water pumps are very common devices that pump various liquids. When the centrifugal pump impeller works, the centrifugal pump impeller receives the reaction force of water, and the reaction force is finally borne by the bearing part, namely the bearing part bears the radial force and the residual axial force when the water pump works. The existing bearing part, particularly a non-driving-end bearing structure, has the defects that the sealing of a bearing cavity is not tight, so that oil in the bearing cavity is easy to leak, water and impurities easily enter a bearing body, and the service life of the bearing is shortened. Therefore, the thin oil lubrication type non-driving end bearing structure is very beneficial.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: aiming at the defects of the product, the thin oil lubrication type non-drive end bearing structure is provided to prolong the service life of the bearing.
The technical scheme of the utility model is realized like this: it includes first (1) of non-drive end bearing body, and first (1) of non-drive end bearing body passes through the bolt fastening in horizontal centrifugal pump body (15) non-drive end one side, characterized by: the inner ring of an angular contact ball bearing (8) is sleeved on the spindle of the horizontal centrifugal pump, the left side of the angular contact ball bearing is fixed through a bearing retaining sleeve (5), a stop washer (4) and a nut (3), and the right side of the angular contact ball bearing is fixed through a bearing retaining sleeve (10); the left side of the outer ring of the angular contact ball bearing (8) is clamped on a boss (17) of the bearing body A (1), the right side of the outer ring is fixed through a bearing gland (14), and the bearing gland (14) and the bearing body A (1) are fixedly connected through a bolt (11) and a flat washer (12).
The utility model discloses better technical scheme is: an oil slinger (6) is arranged between the bearing body A (1) and the angular contact ball bearing (8). The lubricating oil is used for stirring the lubricating oil, so that the lubricating oil is sprayed into the angular contact ball bearing (8) to play a lubricating role. And a lifting ring screw (9) and an air release plug (7) are fixed on the upper part of the non-drive end bearing body A (1) and are used for lifting and oiling. An outer square pipe plug (16) and an oil pointer (2) are arranged at the lower part of the non-driving end bearing body A (1). For maintenance oil drain and level indication. An oil seal (13) is arranged on the inner side of the bearing gland (14). Used for dust and water prevention.
The utility model discloses the bearing chamber is sealed tight, and the oil in the bearing chamber is difficult to reveal, and water and debris are difficult to get into the bearing body moreover, have improved bearing life.

Detailed Description
The invention will be further described with reference to the accompanying drawings:
as shown in fig. 1 and fig. 2, the utility model discloses a including non-drive end bearing body first (1), non-drive end bearing body first (1) passes through the bolt fastening in the non-drive end one side of the horizontal centrifugal pump body (15), characterized by: the inner ring of an angular contact ball bearing (8) is sleeved on the spindle of the horizontal centrifugal pump, the left side of the angular contact ball bearing is fixed through a bearing retaining sleeve (5), a stop washer (4) and a nut (3), and the right side of the angular contact ball bearing is fixed through a bearing retaining sleeve (10); the left side of the outer ring of the angular contact ball bearing (8) is clamped on a boss (17) of the bearing body A (1), the right side of the outer ring is fixed through a bearing gland (14), and the bearing gland (14) and the bearing body A (1) are fixedly connected through a bolt (11) and a flat washer (12). An oil slinger (6) is arranged between the bearing body A (1) and the angular contact ball bearing (8). The lubricating oil is used for stirring the lubricating oil, so that the lubricating oil is sprayed into the angular contact ball bearing (8) to play a lubricating role. And a lifting ring screw (9) and an air release plug (7) are fixed on the upper part of the non-drive end bearing body A (1) and are used for lifting and oiling. An outer square pipe plug (16) and an oil pointer (2) are arranged at the lower part of the non-driving end bearing body A (1). For maintenance oil drain and level indication. An oil seal (13) is arranged on the inner side of the bearing gland (14). Used for dust and water prevention.
