Description
Technical field
The utility model belongs to the technical field of vertical electric pump, is related to a kind of bearing arrangement of vertical electric pump.
Background technique
For the vertical electric pump of high-power minor diameter, bottom end bearing will bear axial force and radial force simultaneously, and load is very
Weight.But due to being limited by motor cavity diameter, used bearing again cannot be excessive, and often small bearing drives big negative in practice
It carries, damage is very easy in the continuing working of electric pump, causes electric pump failure.The bottom end bearing of the high-power vertical electric pump of minor diameter
As the bottleneck in electric pump service life, therefore, the structure of such electric pump bottom end bearing is improved, extend bottom end bearing life, just become
The technical issues of one urgent need to resolve of technical field.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of bearing arrangements of vertical electric pump, greatly improve
The service life of the bottom end bearing of the high-power vertical electric pump of minor diameter.
In order to solve the above technical problems, the purpose of this utility model is achieved by following technical proposals:
A kind of bearing arrangement of vertical electric pump, including motor housing and motor shaft, the bottom end of motor housing are equipped with end cap,
Integrally formed with bearing block above the end cap, it is sequentially installed with from bottom to top in bearing block and bears the bearing one of axial force, holds
By the bearing two of radial force, bearing washer, bearing washer and bearing one and bearing two are provided between bearing one and bearing two
Inner ring connects, the outer ring and bearing block tight fit of bearing one and bearing two, inner ring and motor shaft tight fit.
Preferably, above-mentioned bearing one is angular contact bearing, and above-mentioned bearing two is deep groove ball bearing.
The shaft shoulder, the upper surface contact connectio of the shaft shoulder and two inner ring of bearing are provided on above-mentioned motor shaft.
The outer wall last week of above-mentioned motor housing lower end is equipped with mounting base, and the end cap is bolted connection in mounting base
On.
The top of above-mentioned end cap is assemblied in the inner cavity of motor housing by annular stopper integrally formed with annular stopper, end cap
In.
O-ring seal is arranged on above-mentioned annular stopper, O-ring seal is mounted on the annular groove of motor housing lower end
In.
Compared to the prior art the utility model, has the following beneficial effects:
The bottom head covers of the utility model use the structure of duplex bearing, and the bearing one for bearing axial force is selected in bottom end, in
Between install bearing washer additional, on washer select bear radial force bearing two reduce electricity to greatly improve bearing life
Failure of pump.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model；
Appended drawing reference: 1, motor housing；2, motor shaft；3, end cap；4, bearing block；5, bearing one；6, bearing two；7, bearing
Washer；8, the shaft shoulder；9, mounting base；10, bolt；11, annular stopper；12, O-ring seal.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1:
A kind of bearing arrangement of vertical electric pump, including motor housing 1 and motor shaft 2, the bottom end of motor housing 1 are equipped with end
Lid 3,3 top of the end cap are sequentially installed with the axis for bearing axial force in bearing block 4 integrally formed with bearing block 4 from bottom to top
The bearing 26 for holding one 5, receiving radial force, is provided with bearing washer 7, bearing washer 7 and bearing between bearing 1 and bearing 26
1 and the inner ring of bearing 26 connect, the outer ring of bearing 1 and bearing 26 and 4 tight fit of bearing block, inner ring and motor shaft
2 tight fits.
When vertical electric pump works, motor shaft 2 is rotated, and bearing 1 bears axial force, and bearing 26 bears radial force, thus greatly
Width improves bearing life.
Preferably, above-mentioned bearing 1 is angular contact bearing, and above-mentioned bearing 26 is deep groove ball bearing.
Motor shaft 3 and the installation position limiting structure of bearing are: the shaft shoulder 8, the shaft shoulder 8 and axis are provided on above-mentioned motor shaft 3
The upper surface for holding 26 inner rings connects.
Installation sealing structure between end cap 3 and motor housing 1 is:
It was equipped with mounting base 9 the outer wall last week of above-mentioned 1 lower end of motor housing, the end cap 3 is fastenedly connected by bolt 10
In mounting base 9.
The top of above-mentioned end cap 3 is assemblied in motor housing by annular stopper 10 integrally formed with annular stopper 10, end cap 3
In 1 inner cavity.
O-ring seal 12 is arranged on above-mentioned annular stopper 10, O-ring seal 12 is mounted on the ring of 1 lower end of motor housing
In connected in star.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
Within the scope of.
