Description
Technical field
The utility model is related to a kind of threephase asynchronous, specifically a kind of interpolation type oil pump direct connection motor.
Background technology
At present, the supporting motor of most of oil pumps is that country lists the Y2 Series Motors of superseded catalogue in, it is necessary to update
The minimum threshold of the replacement is YE2 series of high efficiency rate motor, but to improve the efficiency of oil pump systems, to make the performance of oil pump systems
It is improved, is required strongly as the motor special planeization of dragging oil pump.In the prior art, motor must be by shaft coupling
The main shaft connection of device and oil pump, the length of transmission is more long, and the loss late of energy is higher, and noise is larger.Motor and casing, oil
Connection between pump is also relatively cumbersome, and the overall space for taking is larger, and the cost of material is also higher.
Therefore, applicant combines existing technology and requirement, and it is made that in existing technical foundation and is correspondingly improved,
Ultimately provide a kind of interpolation type oil pump direct connection motor.
The content of the invention
The purpose of this utility model is to provide a kind of easy for installation, efficiency high, vibrate low supporting with oil pump of small, noise
Special three-phase asynchronous motor.The motor special is directly realized by direct connection with oil pump, it is ensured that axiality requirement, improves assembling essence
Degree, moreover, the design of electric motor end cap is considered and is directly connected to oil pump case simultaneously, so that motor, oil pump and oil pump
The organic assembling of case, greatly improves the precision of overall design.
To achieve the above object, the technical solution of the utility model, including housing, be connected to the shield of housing right-hand member, set
Terminal box in housing upper end, the end cap being connected with housing left end by bolt, the inside of the end cap are defeated through motor is provided with
Go out main shaft, the end cap is provided with multiple fixing holes, the end cap is fixed with electric machine casing, oil pump and casing respectively by fixing hole
Connection, the motor bearings that main shaft is engaged is provided with and exports in the inside of end cap.
The left end of the output main shaft is provided with coaxial connection cavity, and the connection cavity matches with the end of oil pump rotating shaft
Close.
Due to using above-mentioned technical proposal, the beneficial effects of the utility model to be：The output main shaft of motor is and oil pump phase
The interpolation type structure of cooperation, can save traditional shaft coupling and be directly connected to, and shorten the distance of transmission, reduce bearing assembly,
The motor and oil pump it is supporting into complete machine structure, not only system effectiveness is high, and vibration and noise also diminish, and whole oil pump system
The structure of system is compacter；The end cap of traditional bearing cap and singular association is changed to connect with motor, oil pump and casing simultaneously
The composite end cover for connecing, to coordinate the export structure of relatively short distance, furthermore achieved that the miniaturization of body.
Brief description of the drawings
The utility model is described further in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure：1st, housing, 2, shield, 3, terminal box, 4, end cap, 5, output main shaft, 6, fixing hole, 7, motor bearings, 8,
Connection cavity, 9, bolt.
Specific embodiment
As shown in figure 1, the utility model includes housing 1, is connected to the shield 2 of the right-hand member of housing 1, is located at the upper end of housing 1
Terminal box 3, the end cap 4 being connected with the left end of housing 1 by bolt 9, the inside of the end cap 4 export main shaft 5 through motor is provided with,
The end cap 4 is provided with multiple fixing holes 6, and the end cap 4 is fixed with electric machine casing 1, oil pump and casing and connected respectively by fixing hole 6
Connect, the motor bearings 7 that main shaft 5 is engaged is provided with and exports in the inside of end cap 4.
The left end of the output main shaft 5 is provided with coaxial connection cavity 8, the end phase of the connection cavity 8 and oil pump rotating shaft
Coordinate.
By above-mentioned structure, the output main shaft 5 of motor is coaxially connected with oil pump Direct interpolation formula, shorten transmission away from
From reducing bearing assembly；End cap 4 can be directly connected to motor, oil pump and casing simultaneously by multiple fixing holes 6, to coordinate
The export structure of relatively short distance, furthermore achieved that the miniaturization of body.
