Abstract
The utility model relates to an electric motor rotor apron, including ring female cap board, there is an axial annular in ring female cap board upper surface system, there is the fix with screw hole at the annular equipartition, be the ascending enhancement bulge loop of axial within the annular of ring female cap board, enhancement bulge loop inner edge inwards extends the system has fixed limit, and fixed edge system has a radial square bayonet socket for inlay with the fixture block of base and set the position, be the ascending gas pocket bulge loop of axial beyond the annular of ring female cap board, equipartition gas pocket on the gas pocket bulge loop, the marginal downwardly extending system of gas pocket bulge loop has the blank pressing. The utility model provides an electric motor rotor apron can install at the sheath tip fast, utilizes buckle wherein to fix a position fast, then through its position of bolt fastening, the installation is very convenient, and structural strength is high, and life -span of making the permanent magnet use is longer and the performance is better and the great rotational speed that improves the motor safety work, has promoted the performance of motor.
Description
Technical field
This utility model belongs to motor accessory field, especially a kind of rotor cover plate.
Background technology
Traditional disc-type permanent magnet motor rotor adopts surface-mount type structure mostly, and the permanent magnet of this structure is pasted onto rotor volume
Portion, whole permanent magnet is exposed, and easily causes permanent magnet and damages；And the presence due to centrifugal force, surface-mount type structure cannot
So that motor excessively high speed is run, limit the maximum speed of motor, reduce the performance of motor it is therefore desirable to a kind of rotor
Cover plate.
According to retrieval, find patent documentation related to the application as follows, specific disclosure is as follows:
Patent documentation cn203289217u discloses a kind of disk type electric motor rotor, including rotor cover plate, rotor core and permanent magnetism
Body, rotor cover plate is used for covering rotor core and being fixedly connected with rotor core, and the side wall of rotor core has several and is used for
The magnet steel groove of embedded permanent magnet, magnet steel groove is evenly distributed on the side wall of rotor core, and permanent magnet embeds magnet steel groove and and rotor
Iron core is fixedly connected, and a kind of rotor cover plate disclosed in this patent, is a disk, and interval is formed with radial slot.
Patent documentation cn102644659a discloses a kind of universal high-speed rotation bearing, wherein comprises a construction, by rotor,
Rotor cover plate, rotor retainer forms, and puts into rotor, both sides face covers rotor cover plate in rotor retainer.
Above-mentioned patent is larger with the application difference, does not affect creativeness and the novelty of the application.
Utility model content
In place of the purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of structure simple, quick for installation
Rotor cover plate.
This utility model solves technical problem and be the technical scheme is that
A kind of rotor cover plate, including annular cover, is formed with an axial annular groove in annular cover upper surface, in ring
Groove is evenly equipped with screw fixed hole, is reinforcement bulge loop axially upwards, strengthens convex ring edge inside within the annular groove of annular cover
Extend and be formed with fixed edge, fixed edge is formed with the square bayonet socket of radial direction, for the fixture block setting-in positioning with base, annular lid
It is pore bulge loop axially upwards beyond the annular groove of plate, equal qi-emitting hole on pore bulge loop, pore bulge loop edge extends downwardly and is formed with
Flanging.
Of the present utility model with good effect it is a little:
1st, the rotor cover plate that this utility model provides can be quick installed at sheath ends, can using buckle therein
Quick positioning, is then being bolted its position, is installing very convenient, structural strength is high, making the life-span that permanent magnet uses
Longer and better performances and substantially increase the rotating speed of motor safety work, improve the performance of motor.Three in prior art
The positioning action of bolt hole is complex, and after having square location hole, installation alignment work moment completes.
2nd, the structure of the rotor cover plate that this utility model provides is simple, cheap, and technique is easily achieved.
Brief description
Fig. 1 is the structural representation of the application rotor cover plate；
Fig. 2 is axonometric chart of the present utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following examples are simply retouched
The property stated, be not determinate it is impossible to limit protection domain of the present utility model with this.
A kind of rotor cover plate, including annular cover, is formed with an axial annular groove 2 in annular cover upper surface,
Annular groove is evenly equipped with screw fixed hole 6, for fixing cover plate with rotor core, is axially upwards within the annular groove of annular cover
Reinforcement bulge loop 7, strengthen convex ring edge and extend internally and be formed with fixed edge 3, fixed edge is formed with the square bayonet socket 5 of radial direction, uses
In the fixture block setting-in positioning with base, it is pore bulge loop 1 axially upwards beyond the annular groove of annular cover, on pore bulge loop all
Qi-emitting hole 4, pore bulge loop edge extends downwardly and is formed with flanging 8, for the lid dress with motor sheath.
Using method of the present utility model is as follows:
Assemble sequence is: first permanent magnet is sequentially placed in magnet steel groove, then rotor cover plate and rotor core are passed through spiral shell
Nail is fixed, and last sheath is connected with rotor cover plate and rotor core by interference connection.Rotor cover plate is closer to stator, and
Air gap is left between rotor cover plate and stator.During rotor operating, straight, quadrature axis magnetic circuit is uneven, produces reluctance torque, makes motor
Power density increases, and magnet steel groove is fixed on inside rotor core without the problem worrying centrifugal force simultaneously, so that rotor can be reached
To higher rotating speed.
Above an embodiment of the application is described in detail, but described content has been only the preferable reality of the present embodiment
Apply example it is impossible to be considered the practical range for limiting the application, all impartial changes done according to the application scope and improvement
Deng all should still belong within the patent covering scope of the application.
