Abstract
The utility model discloses a kind of high inlet pressure cantilever pump series shaft bearing apparatus, this device is primarily of bearing support, roller bearing, angular contact ball bearing arranged side by side in the same way, reflex angle contact ball bearing composition; Structure characteristic be impeller end pump shaft on the roller bearing bearing radial load is housed; The pump shaft of coupling end is in series with two, and side by side corner connection ball bearings and a reflex angle are received bearing in the same way.Roller bearing bears large radial load, and floating effect is good, does not bear moment of flexure or flexure; Two corner connection ball bearing shared axial high thrusts backward arranged side by side in the same way, reflex angle contact ball bearing bears radial force, bears the forward thrust in possibility situation simultaneously.This device overcomes other class bearing and is arranged in high inlet pressure cantilever pump, impeller end bearing floating is large, bears moment of flexure and flexure, and the problem of large load lower bearing heating, balance end thrust larger in high inlet pressure cantilever pump, improve bearing working life.
Description
One, technical field
The utility model relates to mechanical engineering pump class technical field, specifically a kind of high inlet pressure cantilever pump series shaft bearing apparatus.
Two, background technique
The bearing arrangement scheme of current China high inlet pressure cantilever centrifugal pump is varied, due to special applying working condition, the bearing of this pump will bear very large to back pressure, the unreasonable bearing life that causes of bearing arrangement reduces greatly, cause high inlet pressure cantilever pump Frequent Troubles, frequency of maintenance is higher, has had a strong impact on the progress of producing.
Three, summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high inlet pressure cantilever pump series shaft bearing apparatus extending bearing working life.
The technological scheme realizing the purpose of this utility model employing is: the series shaft bearing apparatus of this pump is primarily of bearing support, roller bearing, angular contact ball bearing arranged side by side in the same way, reflex angle contact ball bearing composition; The roller bearing bearing radial load the pump shaft of impeller end is equipped with; The pump shaft of coupling end is in series with two, and side by side corner connection ball bearings and a reflex angle are received bearing in the same way.
The utility model compared with prior art its advantage is: one is that impeller end adopts a roller bearing, and can bear large radial load, floating effect is good, does not bear moment of flexure or flexure; Two is two corner connection ball bearing shared axial high thrusts backward arranged side by side in the same way, and reflex angle contact ball bearing bears radial force, bears the forward thrust in possibility situation simultaneously, can not assist completely bear radial force as thrust-bearing thrust; Before this device realizes, step bearing bears radial force, and rear end bearing arranged side by side bears the separation mode bearing high thrust backward.Device overcomes other class bearing and is arranged in high inlet pressure cantilever pump, and impeller end bearing floating is large, bears moment of flexure and flexure, and the problem of large load lower bearing heating; Balance end thrust larger in high inlet pressure cantilever pump, improve bearing working life.
Four, accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the sectional structure chart of the utility model high inlet pressure cantilever pump series shaft bearing apparatus.
In figure: 1. bearing support, 2. roller bearing, 3. arranged side by side angular contact ball bearing in the same way, 4. reflex angle is received bearing.
Five, embodiment
In the accompanying drawings, the utility model high inlet pressure cantilever pump series shaft bearing apparatus forms primarily of bearing support 1, roller bearing 2, angular contact ball bearing 3 arranged side by side in the same way, reflex angle contact ball bearing 4; The roller bearing 2 bearing radial load the pump shaft of impeller end is equipped with; The pump shaft of coupling end is in series with two, and side by side corner connection ball bearings 3 and a reflex angle are received bearing 4 in the same way.The structure adopting a roller bearing to combine with two angular contact ball bearings arranged side by side in the same way and a reflex angle contact ball bearing tandem arrangement, well improves the stressing conditions in high inlet pressure cantilever pump, improves the ride quality of pump.
