Abstract
The utility model provides a kind of bearing arrangement of electric motor for pump, the upper bearing portion dress and bearing portions dress at both ends are filled including being separately positioned on rotor portion, the upper bearing portion dress uses pairs of ball bearing, the bearing portions dress uses single ball bearing, the bearing cap that the upper bearing portion dress and bearing portions fill to be embedded with outside framework oil seal with bearing housing.The utility model has the beneficial effects that bearing arrangement is designed according to its stressing conditions, and it is scientific and reasonable, it is easy to utilize.
Description
Technical field
The utility model belongs to electric motor for pump equipment technical field, more particularly, to a kind of bearing arrangement of electric motor for pump.
Background technology
Bearing arrangement is the key member in electric motor for pump, not only plays gearing, but also have sealing performance, this
Case provides a kind of bearing arrangement of scientific and reasonable electric motor for pump according to the stressing conditions of different location bearing.
Utility model content
The purpose of this utility model is to provide a kind of simple structure and reasonable design, electric motor for pump easy to utilize
Bearing arrangement.
The technical solution of the utility model is：A kind of bearing arrangement of the electric motor for pump of the utility model, including set respectively
It sets and fills the upper bearing portion dress and bearing portions dress at both ends in rotor portion, the upper bearing portion dress uses pairs of ball bearing, institute
It states bearing portions dress and uses single ball bearing, the bearing cap and bearing housing that the upper bearing portion dress and bearing portions fill are embedding
There is outside framework oil seal.
Further, O-ring seal is equipped between the bearing cap and bearing housing.
Further, the electric motor for pump is made of first motor and the second motor.
The utility model has the advantages and positive effects of：
Due to the adoption of the above technical scheme, the stress of bearing arrangement more science；With simple in structure, good seal performance,
It is easy to utilize, the advantages that high financial profit.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：
1- upper bearing portions fill, 2- bearing portions dress, 3- ball bearings, 4- outside framework oil seals, 5-O type sealing rings.
Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the utility model.
As shown in Figure 1, a kind of bearing arrangement of electric motor for pump of the utility model, including it is separately positioned on rotor portion dress
The upper bearing portion at both ends fill 1 and bearing portions fill 2, the determination of bearing arrangement, dependent on the analysis to stressing conditions, and to institute
The distribution that stressing conditions carry out, upper bearing portion fill 1 and pairs of ball bearing 3, bearing portions are used to fill 2 and use single ball bearing 3,
Ball bearing can bear all axially and radially loads, and the medium completely with pump conveying separates.Upper bearing portion dress and under
The bearing cap of bearing portion dress is embedded with outside framework oil seal 4 with bearing housing, and oil sealing will need the component lubricated and go out in transmission parts
Power component is isolated, and is unlikely to allow oil seepage, and in addition skeleton plays the role of reinforcement, and enable oil sealing keep shape and
Power.
O-ring seal 5 is equipped between the bearing cap and bearing housing.
The electric motor for pump is made of first motor and the second motor.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should all still belong within the patent covering scope of the utility model.
