Description
Technical field
The utility model belongs to technical field of motors, is related to a kind of rotor.
Background technique
The rotor of motor is the rotary part in motor, is cooperated with the stator of motor, and rotor carries out after stator energization
Rotation output rotatory force.Existing rotor is generally made of shaft and bodied rotor base, and shaft, which is worn, is fixed on rotor base
On, magnet steel is fixedly installed on rotor base.Rotor base is overlapped by multi-disc silicon steel sheet and is formed by rivet fixation.Rotor base can also
To be called rotor core or rotor subject.
Existing magnet steel is fitted on rotor base circumferential surface by glue, when rotor speed is too fast or glue quantity is insufficient
Shi Junhui is easy to fall off magnet steel, and magnet steel, which falls off, will cause motor damage, it is difficult to work normally.
It is reinforced for this reason, it may be necessary to be mounted on rotor base to magnet steel, existing reinforcing mode such as Chinese Patent Application No.
Shown in a kind of brushless direct current motor inner rotor core for CN201711395262.2, providing rotor includes first end
Lid, second end cover, rotor core, magnet steel, armature spindle and carbon fiber circle, armature spindle are fixed with rotor core, magnet steel circumferentially cloth
It sets on rotor core surface, rotor core is assemblied between first end cover and second end cover, magnet steel outer surface fixed carbon fibrous loop,
Rotor core has through-hole, and the convex block with through-hole cooperation is provided in first end cover and second end cover.
By being arranged fixed carbon outside magnet steel in the patent document of above-mentioned " a kind of brushless direct current motor inner rotor core "
Fibrous loop, and be inserted into the through-hole of rotor core by the convex block of two end caps and to cover two end caps respectively to be located at rotor core
Both ends, to fix to carbon fiber circle and then be reinforced to magnet steel.Have although the patent document reinforces magnet steel
There is certain effect, but two end caps are to be plugged into the through-hole of rotor core to be fixed by convex block, are turned in rotor high speed
End cap high-speed rotation therewith when dynamic, so that end cap is easy to move outside rotor core, it is likely that lead to end cap loose or dislocation, holding
Lid cannot carry out limit to carbon fiber circle and magnet steel after falling off will lead to magnet steel disengaging, therefore the patent document consolidates magnet steel
Determine effect and bad, magnet steel is still easy to fall off.
Summary of the invention
There is the above problem in the utility model, propose a kind of rotor, the utility model institute in view of the prior art
Technical problems to be solved are that magnet steel falls off when how to prevent rotor from rotating.
The utility model is realized by following technical proposal: a kind of rotor, including rotor base and is threaded through rotor
Shaft on base, the both ends of rotor base are respectively arranged with the end cap being threaded through in shaft, multiple magnet steel are provided on rotor base,
It is characterized in that, offers multiple mounting holes through rotor base both ends, the magnet steel one on the rotor base along its length
One correspondence is embedded in mounting hole, and the inner face of two end caps bears against the both ends end face of rotor base, and two end caps is interior
End face bears against the both ends end face of magnet steel, have on the outer peripheral surface of the shaft with one of end cap outer end face against ring
The boss of shape offers the limiting slot of annular in the shaft along its circumferential direction, is provided in the limiting slot another against fixation
The circlip of a end cap outer end face.
Mounting hole is set on rotor base in this rotor, magnet steel is embedded in mounting hole, to be carried out just to magnet steel
Step limit, magnet steel are difficult to fall off from the circumferential direction of rotor base, and end cap, the inner face of two end caps is arranged at the both ends of rotor base
It carries out respectively with corresponding rotor base end face against end cap is while against rotor base end face against the end face of magnet steel, magnet steel
Both ends of the surface respectively by the inner face of two end caps against limit, so that two end caps limit the both ends of magnet steel, this electricity
Boss and limiting slot be set also in shaft in machine rotor, and the outer end face of boss and one of end cap is against in limiting slot
Circlip is set, and circlip carries out against so that two end caps are pressed from both sides in boss and circlip cooperation the outer end face of another end cap
It fastens, so that end cap will not change position in rotation, so that the both ends of magnet steel are firmly lockked, so that magnet steel will not week
It will not fall off to while falling off from the axial direction of rotor base.
In above-mentioned rotor, the mounting hole is circumferentially evenly spaced on along the edge of rotor base end face.Pass through
Above-mentioned setting so that opening up for mounting hole is relatively simple, and edge of the mounting hole along rotor base end face can open up it is more
Mounting hole to meet the stable rotation of rotor high speed, while also enabling magnet steel and electricity so as to which more magnet steel is arranged
More closely realize accurate fit in machine stator position.
In above-mentioned rotor, the rectangular in cross-section of the magnet steel, the mounting hole is strip-shaped hole, the mounting hole
With two inner sidewall close to rotor base center, the lateral wall close to rotor base edge and left and right radial sidewalls, the inside
The width of wall is less than the width of lateral wall, has gap between two radial sidewalls and the surface of corresponding magnet steel.It is set by above-mentioned
It sets so that mounting hole has gap with the magnet steel being mounted in it, consequently facilitating the installation and taking-up of magnet steel.
In above-mentioned rotor, the quantity of the mounting hole is 6-10.The quantity of mounting hole determines the number of magnet steel
Amount, can be arranged enough magnet steel by above-mentioned setting, and it is relatively simple also to open up mounting hole.
In above-mentioned rotor, the end cap includes the mainboard body in circular ring shape, and the edge of the mainboard body is along week
To the lug boss with annular, the end face of the lug boss is simultaneously against the end face of magnet steel and the end face of rotor base.By above-mentioned
The lug boss that end cap is arranged be tightened against to magnet steel that magnet steel is avoided to fall off.
In above-mentioned rotor, the end cap is plastic end cover.By above-mentioned setting so that the insulation of rotor
Property is good, good every magnetic property and at low cost.
Compared with prior art, this rotor has the advantage that
1, mounting hole can be arranged on rotor base in the utility model, and magnet steel is embedded in mounting hole, thus to magnet steel into
Row limit, magnet steel are difficult to fall off from the circumferential direction of rotor base, while two end caps are arranged and limit to the both ends of magnet steel, so that magnetic
Steel is comprehensive to be limited on rotor base.
2, the utility model also passes through boss and circlip cooperation is clamped fixation to two end caps, so that end cap is rotating
When position will not change, thus firmly lock magnet steel both ends, it is ensured that magnet steel will not fall off.
3, end cap uses plastic end cover in the utility model, so that the utility model good insulating, good every magnetic property, and
It is at low cost.
