Description
Technical field
The present invention relates to motor production technical field, more particularly to a kind of mounting means of magnet steel.
Background technology
Motor is typically to be made up of stator and rotor, and rotating shaft, rotor core and rotor windings are included on rotor, are pacified on stator
Equipped with coil.In order to rotate motor, it is necessary on rotor mounting magnetic steel, and give coil electricity.Magnetic field caused by magnet steel
With coil electricity caused by magnetic field produce interaction force so that rotor rotate.
The mounting means of existing magnet steel needs to cover frock in rotating shaft or rotor core, so as to which magnet steel be inducted into
In the magnet steel mounting groove of rotor core, after installation, then frock removed, put end plate fixation.This mounting means
The mounting tool in rotating shaft or rotor core in advance is needed, after magnet steel installs, it is also necessary to remove frock, installation steps ratio
It is cumbersome, operation inconvenience.
The content of the invention
It is an object of the invention to provide a kind of mounting means of magnet steel, to simplify the installation step of the magnet steel in rotor core
Suddenly.
To reach above-mentioned purpose, basic technology scheme of the invention is：A kind of mounting means of magnet steel, including lamination, peace
Dress magnet steel and end plate are fixed, and in lamination step, take rotating shaft and some punchings, punching is provided with some magnet steel mounting holes, will be some
Punching is enclosed in rotating shaft, and builds up rotor core, the magnet steel mounting hole face of punching is formed magnet steel mounting groove, the outer wall of rotating shaft
Protuberance is provided with, protuberance is elongated, and protuberance is axially distributed along rotating shaft, has before lamination step and makes end plate step
Suddenly, there is installation end plate step between lamination step and mounting magnetic steel step；The step of making end plate is chooses the metal of exhausted magnetic
Plate, shaft hole is stamped out in the middle part of metallic plate, and guiding groove is opened up on shaft hole, if being provided with the surface of metallic plate solid
The push-in hole determined hole and matched with magnet steel mounting groove；It is that the guiding groove of end plate is enclosed on to the protuberance of rotating shaft to install end plate step
On, and end plate is slided along protuberance to rotor core, and make push-in hole and magnet steel mounting groove face, finally end plate is fixed and connected
It is connected in rotating shaft；Mounting magnetic steel step is that magnet steel is passed through into push-in hole and is pushed into magnet steel mounting groove；End plate fixing step is
It is screwed into the outboard cover closing lid plate of end plate, and using fixture through cover plate in fixing hole.
The principle of this programme is：1st, when being slided in rotating shaft, the protuberance of guiding groove and rotating shaft coordinates end plate, so that end
Plate along protuberance to rotor core slide, end plate is positioned, prevent end plate in sliding process and slip after and rotating shaft
It was found that relatively rotating, misplaced so as to prevent from being pushed into hole with magnet steel mounting groove, improve installation accuracy.2nd, hole and magnet steel mounting groove are pushed into
After face, magnet steel is pushed into magnet steel mounting groove by being pushed into hole, in magnet steel installation process, the metal end plate of exhausted magnetic can be by magnetic
Steel and rotor core are kept apart, and prevent from producing huge magnetic force between magnet steel and rotor core, magnet steel is pushed into magnet steel mounting groove
In need not overcome magnetic force, can easily be pushed into magnet steel mounting groove, be easy to the Fast Installation of magnet steel.3rd, fixture may pass through cover plate
It is screwed into fixing hole, so as to which push-in hole be blocked, when preventing that rotor core from rotating at a high speed, magnet steel flies out from push-in hole.
This programme has the beneficial effect that：1st, guiding groove is engaged with protuberance, prevents end plate from relative slip occurring in rotating shaft,
So as to prevent the magnet steel mounting groove in the push-in hole of end plate and rotor core from misplacing, because of push-in hole and magnet steel mounting groove face, therefore magnetic
Steel is pushed into magnet steel mounting groove by being pushed into hole can, and guiding groove serves the positioning function of frock, in mounting magnetic steel mistake
Cheng Zhong, without installing and removing frock again, the function of end plate and frock is combined into one, the step of simplifying installation, saves peace
ETL estimated time of loading, improve operating efficiency.The 2nd, end plate is first installed, and end plate is the metallic plate of exhausted magnetic, and end plate can be by magnet steel and rotor
Iron core separates, and magnet steel is pushed into push-in Kong Houke and is smoothly pushed into magnet steel mounting groove, without overcoming magnet steel and rotor core
Between magnetic force, magnet steel is pushed into it is more laborsaving in magnet steel mounting groove, so as to improve operating efficiency.
Further, in mounting magnetic steel step, glue is scribbled in the inwall of magnet steel mounting groove and the outside of magnet steel.Glue can
Make bonding magnetic steel in magnet steel mounting groove, be fixed on magnet steel more firm in magnet steel mounting groove.Cover plate is blocked hole is pushed into, no
It can only prevent magnet steel from being flown out from push-in hole, also prevent glue and flowed out from push-in hole, improve security performance.
Further, in lamination step, insulating barrier is provided between adjacent punching.Insulating barrier can prevent from leading between adjacent punching
Electricity, reduce the galvano-cautery of punching.
Further, Kong Weiyi push-in group of adjacent two push-in, fixed hole position is between adjacent push-in group.Fixed hole position
Between adjacent push-in group, fixture can uniform fixed charge method end plate, make end plate uniform force, prevent rotor in rotation process, hold
Plate discontinuity and damage.
Further, fixture is screw.Screw is common fixture, is easily configured and buys, cost is relatively low.
Further, the cross sectional shape of guiding groove is square that, compared to the guiding groove that section is circular arc, can prevent protuberance from existing
Skidded in guiding groove, so that positioning is more stable accurate.
Further, it is fixedly connected between end plate and rotating shaft by ring key, ring key is enclosed in rotating shaft, and is offseted with end plate, ring
Key welds with rotating shaft, end plate respectively.Ring key is enclosed in rotating shaft to be welded with rotating shaft, end plate respectively, so as to which end plate is fixed on into rotating shaft
On end plate, rotor is prevented in high-speed rotation, and end plate moves to both sides.Also, with end plate directly is welded on into rotating shaft
On compare, end face and the end plate of ring key offset, and increase the lifting surface area of end plate, in dispersible rotor rotation process, end plate institute
The power being subject to, it is fixed on end plate more firm in rotating shaft.
