Description
Technical field
The utility model is related to the steady head technical field of increasing, more particularly to a kind of brand-new horizontal stage electric machine structure.
Background technology
The structure continued at present more than horizontal stage electric machine on the market using power motor is made, the specific table of its shortcoming
Now：Rotor accessory and stator combination collocation are unsightly, weight is big, assembly difficulty is high, and motor operation rotation produce it is dynamic
Rotor concentricity, the parallelism precision of power are low.
Motor outward appearance：Traditional heads rotor part adds armature spindle combination knot using support magnetic conduction steel ring inner ring outside aluminium end cap
Be configured to rotor, outward appearance steel ring, end cap, rotating shaft material are different, cause surface treatment after color can exist it is larger
Difference, influences the overall appearance of motor；
Motor performance：Be divided into electric property and mechanical performance, a motor it is good with it is bad, all unify situation in electric property
Under, its topmost determinant is exactly that the mechanical performance of motor will be met, and a motor could be allowed more stable durable；This structure
Master is to illustrate that mechanical performance, what mechanical performance embodied is exactly the rotor of the operation rotation of motor, and conventional rotors are most common to be led
Cause problem has two factors：1st, it is the accurate fit tolerance of needs that aluminium end cap, magnetic conduction steel ring, three parts of armature spindle, which coordinate,
It is undesirable that the tolerance of any one part is done, and can ring radially wobbling and swinging laterally, 2, workman and machine for whole rotor
The rigging error of device, reference plane is not parallel or part is not put into position and can cause radially wobbling and horizontal pendulum for whole rotor
It is dynamic；2 points of the above is during volume production, because uncontrollable factor is too many, therefore generation technology defect.
Utility model content
The purpose of this utility model is and a kind of brand-new head proposed in order to solve shortcoming present in prior art
Electric machine structure.
To achieve these goals, the utility model employs following technical scheme：
A kind of brand-new horizontal stage electric machine structure, the rotor is provided with rotating shaft, and rotor uses with rotating shaft and is integrally formed knot
Structure, the rotor is provided with end cap housing, and the inside of the end cap housing is provided with toroidal cavity, the toroidal cavity provided with fixed
Magnetic conduction steel ring is additionally provided with sub- assembly, the toroidal cavity, and magnetic conduction steel ring is connected with end cap housing, is set on the magnetic conduction steel ring
There is magnet ring, and magnet ring is additionally provided with jump-ring slot, the jump-ring slot on the inside of toroidal cavity, the rotating shaft and is provided with jump ring,
And one end of jump ring offsets with rotating shaft.
Preferably, the rotor, end cap housing and magnetic conduction steel ring use integrated formed structure.
Preferably, the magnetic conduction steel ring is located at the inside of end cap housing.
Preferably, the end cap housing is made of aluminium alloy.
In the utility model, mainly include：Rotor, magnetic conduction steel ring, magnet ring and field frame assembly, rotor is by Digit Control Machine Tool
One-time turning machine-shaping, rotating shaft between rotor without fastener, it is to avoid the circle bounce caused by Split type structure, it is different
The assembly problems such as axle.The toroidal cavity of a placement magnetic conduction steel ring is left in rotor, toroidal cavity is in ladder inner circle shape, magnetic conduction
Steel ring is bonded together by glue with rotor, and magnet ring is placed on magnetic conduction steel ring endoporus, formation rotor to magnetic conduction steel ring to magnet ring
Concentric structure, effectively forms magnetic circuit.The latch-up structure of rotating shaft and field frame assembly is that jump ring and jump-ring slot coordinate locking
Structure, rotating shaft lower end is extend out to outside field frame assembly, and rotating shaft lower end is provided with annular groove, i.e. jump-ring slot, and jump ring external diameter is more than outside rotating shaft
Footpath, jump ring is caught in annular groove, and jump ring acts against bearing inner race and deviate from limiting rotating shaft from field frame assembly, and now rotating shaft is suitable
In the entirety that can only be rotated on field frame assembly, and jump ring just serves the locking action of rotating shaft and field frame assembly.
The beneficial effects of the utility model：
1st, compared with traditional heads motor, because without fit-up gap, and rotor portion covers whole magnetic conduction steel ring
Lid, rotor appearance is an one-piece parts, is surface-treated no aberration, and outward appearance can be consistent.
2nd, compared with traditional heads motor, traditional heads rotor is using the cylindrical circumference of end cap and magnetic conduction steel ring inner circle
Circumference is interference fitted, and this matching relationship is higher to matching requirements, and the assembling process rotor not in place that may result in is rocked
Or the problems such as imbalance.The utility model construction rotor carries out interference fits using the cylindrical circumference of end cap circumference and magnetic conduction steel ring
The traditional interference fit of substitution, effectively reduces assembly difficulty.
3rd, compared with traditional heads motor, part horizontal stage electric machine rotor can be using end cap and the integrally formed skill of magnetic conduction steel ring
Art is made, although such design reduces part, but also needs to be pressed into rotating shaft, during assembling rotating shaft due to batch
The factor such as operative and aided manufacturing machine equipment of measuring, still can cause production technology defect, therefore can not solve root problem；
Another needs magnetic conduction due to magnet ring, so can not be processed using non-magnet material, such as almag, titanium alloy or non-gold
Belong to material etc., can only be made using steel, the density ratio of steel is higher so the weight of rotor entirety is heavier, this practicality
Novel rotor end cap housing can use aluminium alloy or other metal materials, or even process for un-metal material rotor endcap housing and turn
Axle integral part is interior again to inlay magnetic conduction steel ring, it is ensured that while the magnetic circuit of magnet steel periphery is unimpeded, saves workman's assembling rotating shaft process,
The weight of rotor is alleviated again.
4th, compared with traditional heads motor, traditional heads rotor is viscous by end cap and magnet steel shell combination, then brush coating
Magnet steel is connect, then rotating shaft is pressed into rotor endcap centre bore and is combined into complete rotor, assembling process is inevitably led
Cause rotor deformation or bounce, concentricity, parallelism tolerance are typically in 0.04-0.1mm, and to get over high tolerance even more big with motor
Size.The utility model rotor has end cap housing and rotating shaft to be to be integrally machined out, the cylindrical and end of each end cap housing
The concentricity in face, parallelism tolerance can be guaranteed, and tolerance can be controlled within 0.02mm, even more small.
