Description
Technical field
The utility model relates to a kind of groove type magnetic-suspension linear motor primary iron cores.
Background technique
Currently, magnetic-suspension linear motor is widely applied in track transportation industry, the requirement of medium-and low-speed maglev rail locomotive
Electric machine structure is compact, light-weight, and antivibration kinetic force is strong, the particular/special requirement of application, and linear motor must be into one in structure
Step optimization, it is simple and reliable for structure, become the new approaches of medium-and low-speed maglev locomotive linear motor design.
Generally using traditional gusset as tooth support, tooth pressure pressing plate is distributed in core stamping two sides, passes through existing iron core
After the screw bolt and nut fastening of the core stamping and tooth support that penetrate, the gusset tooth support of two sides is welded admittedly finally by pulling plate
It is fixed.The gusset of this mode needs brake forming, and manufacturing process load, manufacture difficulty is larger, and pulling plate location dimension is difficult to ensure,
Core stamping is difficult to ensure that production precision is subject to certain restrictions with tooth support and pulling plate globality.
Alternatively, the iron core back side uses concave structure simultaneously using a kind of tooth support of plane and using a kind of concave structure,
Pulling plate uses convex shape, and pulling plate, which passes through iron core back side groove and forms one, argues entirety, and two sides of arguing are then passed through tooth support, weld
Molding forms an overall structure, this evolutionary approach reduces certain welding position quantity, and formation overall structure precision is higher, adds
Work difficulty increases.
Summary of the invention
The purpose of the utility model is to provide a kind of groove type magnetic-suspension linear motor primary iron cores, can either meet knot
Structure intensity requirement, while can be reduced processing and manufacturing difficulty again, improve production efficiency.
The technical scheme adopted by the utility model to solve the technical problem is as follows: it includes core stamping, tooth support, spiral shell
Bar, mounting plate and nut, mounting plate are set to the back of core stamping, and tooth support is set to the two sides of core stamping, iron core punching
Piece and tooth support are fastened by screw rod and nut, and fluted and mounting plate two sides boss is arranged on tooth support and is cooperatively connected, iron core
There are faying faces for punching back and mounting plate two sides.
The structure of the tooth support two sides and mounting plate cooperation is groove, and mounting plate two sides are cooperated using boss, iron core punching
The back of piece is plane, so that mounting plate boss plane and iron core plane are overlapped, so as to two sides welding.
The groove or boss can be dovetail form or T shape or triangle.
Mating surface is arranged in mounting plate and core stamping, and mating surface cooperates core stamping and mounting plate by welding manner
It is formed whole.
The boss of groove and installation board ends on the tooth support uses welding fabrication, so that tooth support and mounting plate shape
At an entirety.
By welding, it is whole that core stamping, tooth support and mounting plate form iron core.
The mounting plate is provided with weight structure, and for duplicate removal structure setting at two sides or middle part, middle part duplicate removal is kidney slot, and two
Side duplicate removal is square hole.
The beneficial effects of the utility model are: structure is more simple, manufacture easy to process, improve manufacture efficiency, reduce at
This.
