Description
Technical field
The invention belongs to electromechanics field more particularly to the cooling technology of motor, especially a kind of rotor cooling oil
Line structure.
Background technique
New-energy automobile is widely used.Wherein, hybrid vehicle joined electricity on the basis of conventional fuel oil car
Drive system can work together with engine.Motor is integrated in gearbox by part hybrid vehicle, motor stator
Cooling structure realization it is relatively easy, but rotor is to be integrated with speed change on the basis of conventional motors rotor mounting structure
A part of tooth shaft in case, therefore in the design of rotor cooling oil path, it is also necessary to take into account the lubrication of tooth shaft.But it is existing
In technology, the structure that rotor uses can not efficiently use the lubricating oil in gearbox and be cooled down and realized to rotor pair
The lubrication of tooth shaft.
Summary of the invention
It is an object of the invention to overcome disadvantage of the existing technology, provide it is a kind of using gear box oil to motor turn
Son is cooled down, while can wash away in time tooth shaft abrasion powder in rotor, prevents from being adsorbed on influence motor on rotor
Can be with the oil channel structures of quality, heat dissipation performance is high and structure is simple.
This rotor cooling oil circuit structure of the invention, rotor core, rotor field spider including coaxial arrangement, tooth shaft
With dynamic balancing plate, the rotor field spider both ends are arranged in the dynamic balancing plate, and the tooth shaft is fixed with rotor field spider,
In, the rotor field spider is hollow cylindrical structure, its axial direction is provided with two or more on the outer circumference surface of rotor field spider
First oil groove of number, first oil groove is distributed uniformly and circumferentially in the outer circumference surface of rotor field spider, any one
The bottom of a first oil groove is respectively along at least one intercommunicating pore that has been arranged radially of rotor field spider, the inner cavity of rotor field spider and the
One oil groove is connected to by the intercommunicating pore, and the inner peripheral surface of rotor core and the first oil groove cooperatively form tubulose oil circuit, described
Tubulose oil circuit along the dynamic balancing plate for axially extending to rotor field spider both ends of rotor field spider, any one dynamic balancing plate is at it
With in the mating surface of rotor core respectively be radially provided with the first oil groove the second oil groove equal in number, any one
Second oil groove is respectively connected to first oil groove.
Further, the section of first oil groove is U-shaped or rectangle.
Further, second oil groove is fan groove or V-shaped groove.
Further, the axle center of tooth shaft is axially disposed an oil inlet through-hole, the oil inlet through-hole and rotor field spider it is interior
Chamber connection.
The working principle of the invention is：After electric motor starting under the action of the centrifugal force, between rotor field spider inner cavity and tooth shaft
Cooling oil enters the tubulose oil circuit of rotor core and rotor field spider outer circumference surface oil groove composition by intercommunicating pore, and cooling oil is in pressure
It flows to the dynamic balancing plate at both ends under effect along tubulose oil circuit respectively, and passes through the oil groove on dynamic balancing plate and rotor core mating surface
It radially throws away, completes the cooling to rotor and armature ends winding.
The present invention compares with prior art, and effect is positive and apparent.The present invention passes through in rotor field spider and dynamic
Cooling oil path is set on balance plate, it is cold to rotor progress using gear box oil to realize the motor being integrated in gearbox
But, while in cooling procedure tooth shaft abrasion powder in rotor can be washed away, preventing it to be adsorbed on rotor influences motor
Performance and quality, the oil channel structures heat dissipation performance is high, structure is simple.
Detailed description of the invention
Fig. 1 is cooling oil circuit structure schematic diagram of the invention.
Fig. 2 is the schematic diagram of the section structure of the invention.
Specific embodiment
Embodiment 1:
As depicted in figs. 1 and 2, this rotor cooling oil circuit structure of the invention, rotor core 1 including coaxial arrangement,
Rotor field spider 2, tooth shaft 3 and dynamic balancing plate 4, for the setting of dynamic balancing plate 4 at 2 both ends of rotor field spider, rotor field spider 2 is hollow cylinder
Structure, opens up the first oil groove 5 of more than two numbers on the outer circumference surface of rotor field spider 2 along axial direction, the quantity of the first oil groove 5,
Cross sectional shape and size determine that the first oil groove 5 is circumferentially evenly distributed on 2 outer circumference surface of rotor field spider according to required oil mass,
At least one intercommunicating pore 6 is disposed radially in first oil groove 5, the inner cavity of rotor field spider 2 and the first oil groove 5 pass through intercommunicating pore 6
Connection, the inner peripheral surface of rotor core 1 and the first oil groove 5 cooperatively form tubulose oil circuit 7, tubulose oil circuit 7 axially extend to turn
4 at the dynamic balancing plate at 2 both ends of submounts, in dynamic balancing plate 4 and 1 mating surface of rotor core with 5 corresponding position edge of the first oil groove
It is radially provided with the second oil groove 8, the first oil groove 5 is connected with the second oil groove 8 on two sides dynamic balancing plate 4.
Further, the section of the first oil groove 5 is U-shaped or rectangle.
Further, the second oil groove 8 is fan groove or V-shaped groove.
