Abstract
The utility model relates to a multistage centrifugal pump bearing arrangement, comprising a shaft, which is characterized in that: a cylindrical roller bearing is arranged on a shaft on one side of a coupling. An outer ring of the cylindrical roller bearing is arranged inside a bearing body; two sides of the cylindrical roller bearing are provided with a bearing cover C and a bearing cover D; and the bearing cover C, the bearing body, and the bearing cover D are coupled by a bolt. A cylindrical roller bearing is arranged on the other side of the shaft; an outer ring of the cylindrical roller bearing is arranged inside the bearing body; two sides of the cylindrical roller bearing are provided with a bearing cover A and a bearing cover B; and the bearing cover A, the bearing body, and the bearing cover B are coupled by the bolt. An inner ring and an outer ring of the cylindrical roller bearing are relatively independent; and the inner and outer rings can relatively move axially. An angular contact ball bearing is arranged in the bearing cover A; the dimension of the inner diameter of the angular contact ball bearing is less than the diameter of the axial end, and the axial end plane is vertical to the shaft. The utility model has the advantages that: the installation of a thrust disc can be saved, and axial over-range motion is limited on the basis of slightly changing the original structure.
Description
Technical field
The utility model relates to a kind of multistage centrifugal pump bearing configuration.
Background technique
The multistage centrifugal pump of early stage design, more with gland sealed, multistage pump needs balancing axial thrust when operation, and axle can move around vertically.Move axially the packing seal did not influence, and now along with development of technology, mechanical seal is popularized and is used, and mechanical seal has been to having moved axially strict demand, and large-scale multistage pump generally comes the super scope of restrictive axial to move with thrust disc.The thrust disc part is many, the accuracy of manufacturing height, and the cost height should not be produced in batches at the compact multi-level pump.
Summary of the invention:
The purpose of this utility model is that multistage centrifugal pump needs thrust disc to come the super scope of restrictive axial to move existing the problems referred to above in the solution prior art, and a kind of multistage centrifugal pump bearing configuration is provided.The utility model designs a kind of multistage centrifugal pump bearing configuration, comprise axle, it is characterized in that: connect coupling one side the axle on roller bearing is housed, the outer ring of roller bearing is in bearing support, there are bearing gland and bearing gland in the both sides of roller bearing, one Bolt Connection bearing gland is arranged, bearing support and bearing gland, on the opposite side of axle roller bearing is housed, the roller bearing outer ring is in bearing support, there are bearing gland and bearing gland in the roller bearing both sides, the Bolt Connection bearing gland, bearing support and bearing gland, the roller bearing Internal and external cycle is relatively independent, Internal and external cycle can relatively move vertically, and angular contact ball bearing is housed in bearing gland, and the angular contact ball bearing internal diameter size is less than the axle head diameter, the axle head plane is square with the axis, the utility model has the advantages that the installation that can save thrust disc, on the basis of slightly changing original structure, the super scope of restrictive axial moves.
Description of drawings:
Figure is a structural representation of the present utility model,
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment:
Comprise axle 1 among the figure, it is characterized in that: roller bearing 3 is housed on 1 at the axle that connects coupling 2 one sides, the outer ring of roller bearing 3 is in bearing support 4, there are bearing gland 5 and bearing gland 6 in the both sides of roller bearing 3, one bolt, 7 coupling bearing glands 5 are arranged, bearing support 4 and bearing gland 6, on the opposite side of axle 1 roller bearing 8 is housed, roller bearing 8 outer rings are in bearing support 9, there are bearing gland 10 and bearing gland 11 in roller bearing 8 both sides, bolt 12 coupling bearing glands 10, bearing support 9 and bearing gland 11, roller bearing 8 Internal and external cycles are relatively independent, Internal and external cycle along axle 1 to relatively moving, angular contact ball bearing 13 is housed in bearing gland 10, angular contact ball bearing 13 internal diameter sizes are less than the axle head diameter, the axle head plane is square with the axis, it is characterized in that: angular contact ball bearing 13 is controlled at 1～1.5mm with the end play.
When pump in when operation, axial tail end shifting balance axial force, as mobile 1～1.5mm, axle head pushes up angular contact ball bearing, the excess of angular contact ball bearing restrictive axes moves, and bears axial force.
Claims (2)
1. multistage centrifugal pump bearing configuration, comprise axle, it is characterized in that: connect coupling one side the axle on roller bearing is housed, the outer ring of roller bearing is in bearing support, there are bearing gland C and bearing gland D in the both sides of roller bearing, one Bolt Connection bearing gland C is arranged, bearing support and bearing gland D, on the opposite side of axle roller bearing is housed, the roller bearing outer ring is in bearing support, there are bearing gland A and bearing gland B in the roller bearing both sides, Bolt Connection bearing gland A, bearing support and bearing gland B, the roller bearing Internal and external cycle is relatively independent, and Internal and external cycle can relatively move vertically, in bearing gland A, angular contact ball bearing is housed, the angular contact ball bearing internal diameter size is less than the axle head diameter, and the axle head plane is square with the axis
2. by the described a kind of multistage centrifugal pump bearing configuration of claim 1, it is characterized in that: angular contact ball bearing and end play are controlled at 1～1.5mm.
