Description
Technical field
The utility model relates to a kind of rotor, particularly relates to the preposition rotor of a kind of electric motor car.
Background technology
Mostly the rotor of existing motor is multiple rotor sheet to adopt the mode of punching press or gluing to make, the connected mode of punching press and gluing also exists the problem that between rotor sheet and rotor sheet, degree of being connected firmly is not high, the rotor that gluing processes can because of the fever expansion that works long hours, reduce the bonding strength between rotor sheet and rotor sheet, thus cause rotor that leakage field phenomenon operationally occurs, reduce the job stability of rotor, shorten the useful life of rotor.
Utility model content
The utility model object to reduce the problem of working rotor stability, provides that a kind of capability and performance is good, degree of being connected firmly is high, the preposition rotor of the electric motor car of long service life.
In order to solve the problem, the utility model by the following technical solutions:
The preposition rotor of a kind of electric motor car, comprises rotor sheet, installing ring, connecting plate, installing hole, groove post, trough rim, slotted eye, riveting button, draw-in groove and binding groove, is characterized in that: described installing ring is arranged on the center of rotor sheet, and is connected with rotor sheet by connecting plate, rotor sheet, installing ring, connecting plate adopts overall punch forming, improve bonding strength, described installing hole is arranged on installing ring, be convenient to the installation of rotor, described groove post is arranged on rotor sheet, and trough rim is provided with on groove post, described slotted eye is set to " U " shape, and between groove post and groove post, described riveting button is separately positioned on rotor sheet and connecting plate, and the riveting button be evenly distributed can improve the bonding strength between rotor sheet and rotor sheet, and then improves the capability and performance of rotor, the useful life of Extending Rotor, described draw-in groove, binding groove is all arranged on rotor sheet, and binding groove and draw-in groove one_to_one corresponding are arranged on the side of draw-in groove, in draw-in groove and binding groove, be provided with magnetic shoe, can keep stability during working rotor.
As preferably, described connecting plate, its quantity is 3-6;
Further, described riveting button, its quantity is 8-16;
Further, described draw-in groove, its quantity is 4-6.
Beneficial effect: the utility model is provided with connecting plate between rotor sheet and installing ring, and riveting button is provided with on rotor sheet and connecting plate, greatly can strengthen the bonding strength between rotor sheet and rotor sheet, and then improve the capability and performance of rotor, in draw-in groove and binding groove, be provided with magnetic shoe, the magnetic force of rotor can be strengthened, again can preventing rotor leakage field, the stability of working rotor can be kept, improve the operating efficiency of rotor.
