The utility model proposes a kind of rotor assembly.
In the embodiment of the utility model one, referring to figs. 1 to Fig. 4, the rotor assembly 1 includes：
Rotating shaft 10, including be sequentially connected vertically canned paragraph 120, construction section 110, spacing section 130, the canned paragraph
120 are provided with lock piece 30, and the outer peripheral face of the construction section 110 is provided with anti-slip part 111, and described spacing section 130 is provided with and protrudes from
The defining flange 131 of the outer peripheral face of construction section 110；And
Rotor 20, the construction section 110 is sheathed on, the anti-slip part 111 abuts with the inner peripheral surface of the rotor 20, described
Rotor 20 is clamped and fastened between the lock piece 30 and the defining flange 131.
Specifically, for the rotating shaft 10, canned paragraph 120, construction section 110 and spacing section 130 are in be coaxially disposed, rotor
20 are arranged and are installed on construction section 110 from one end close to canned paragraph 120, and the external diameter of the canned paragraph 120 is less than or equal to installation
Outside section 110, in order to the installation of rotor 20.In order to prevent rotor 20 from being relatively rotated with rotating shaft 10, the periphery of rotating shaft 10
Face is provided with anti-slip part 111, and the anti-slip part 111 abuts in the inner peripheral surface of rotor 20, forms tight fit, so can reduce rotating shaft 10 with
The probability that rotor 20 relatively rotates.The way of realization of anti-slip part 111 has a variety of, such as can be provided in the periphery of construction section 110
The non-slip texture or convex tendon in face, the relative rotation between rotor 20 and rotating shaft 10 can be limited, is not especially limited herein.
In the present embodiment, lock piece 30 is provided with canned paragraph 120, when rotor 20 is sheathed on construction section 110, rotor 20
Side abutted with the one side of defining flange 131 towards canned paragraph 120, the another side of rotor 20 abuts with lock piece 30,
And then rotor 20 is gripped.Wherein, the way of realization of the lock piece 30 has a variety of, for example, pin feature, clip spring structure or
Person's threaded fastener etc., spacing section 130 of defining flange 131 are preferably set in a ring along spacing section 130 of circumference, are turned with improving
The uniform force of son 20, is easy to preferably fixed rotor 20.Fixed using interference fit compared to rotating shaft 10 and rotor 20
Usual manner, this programme significantly reduce the installation difficulty of rotor 20 and rotating shaft 10, when needing to dismantle separation rotor 20 and rotating shaft
When 10, lock piece 30 need to only be pulled down from canned paragraph 120, you can rotor 20 is dismantled to separation from rotating shaft 10 easily, greatly
The big labor intensity for reducing unloading process.
Technical solutions of the utility model ensure by using the setting anti-slip part 111 on the construction section 110 of rotating shaft 10
Rotor 20 will not relatively rotate after installing with rotating shaft 10, meanwhile, the canned paragraph 120 of rotating shaft 10 is provided with lock piece 30, turns
Spacing section 130 of axle 10 is provided with defining flange 131, so by rotor 20 be clamped and fastened on defining flange 131 and lock piece 30 it
Between, in this way, reducing rotor 20 and the assembly difficulty of rotating shaft 10, also separate beneficial to the dismounting of rotor 20 and rotating shaft 10, effectively carry
The high removal efficiency of rotor 20 and rotating shaft 10.
Further, in the present embodiment, above-mentioned anti-slip part 111 is preferably along the anti-of the axially extending setting of construction section 110
Sliding muscle 112, the corresponding construction section 110 of rotor 20 are provided with mounting hole 211, and the hole wall of mounting hole 211 corresponds to anti-skidding muscle 112 and is provided with
Antiskid groove 212, anti-skidding muscle 112 are located in antiskid groove 212, in this way, relative turn of rotor 20 and rotating shaft 10 can be limited effectively
It is dynamic.Rotor 20 is arranged be installed on rotating shaft 10 when, the antiskid groove 212 of rotor 20 is alignd with the anti-skidding muscle 112 of rotating shaft 10,
So that anti-skidding muscle 112 along rotating shaft 10 axially into antiskid groove 212, complete the location and installation of rotor 20 and rotating shaft 10.
It is understood that reference picture 5 and Fig. 6, in order to strengthen the limit effect of anti-skidding muscle 112, anti-skidding muscle 112 is preferably set
It is equipped with multiple, and circumferentially-spaced distribution of multiple anti-skidding muscle 112 along construction section 110.In order that rotating shaft 10 and the stress of rotor 20 are equal
Even, circumference of the plurality of anti-skidding muscle 112 along construction section 110 is evenly distributed.
Reference picture 6, and Fig. 1 to Fig. 3 is combined, in the present embodiment, rotor 20 includes the iron core being sheathed on construction section 110
210 and the magnetic shoe 220 located at the outer peripheral face of iron core 210, construction section 110, which is corresponded to, on iron core 210 is provided with mounting hole 211, the mounting hole
211 hole wall opens up antiskid groove 212；Anti-skidding muscle 112 is connected towards one end of defining flange 131 with defining flange 131.Such as
This so that for iron core 210 during being arranged and being installed on construction section 110, iron core 210 remains will not occur phase with rotating shaft 10
To rotating, the accurate installation of iron core 210 ensure that.Preferably, the thickness one of the development length of the anti-skidding muscle 112 and iron core 210
Cause, further ensure iron core 210 and the accurate installation of rotating shaft 10.
In order to further prevent rotating shaft 10 and rotor 20 from relatively rotating, in the above-described embodiments, anti-skidding muscle 112 is with preventing
Sliding groove 212 is interference fit.Projection semicircular in shape of the anti-skidding muscle 112 on the shaft section of rotating shaft 10, square or triangle are set
Put, the shape of antiskid groove 212 is adapted with the shape of anti-skidding muscle 112, to cause anti-skidding muscle 112 and antiskid groove 212 to pass through
The less magnitude of interference coordinates, and ensures that iron core 210 can be sheathed on construction section 110 easily, reduces assembly difficulty.
Above-mentioned lock piece 30 is preferably adopted as pre-load nut, and now, the outer peripheral face of canned paragraph 120 is provided with external screw thread, in advance
Tight nut is engaged with the external screw thread on canned paragraph 120, and then reliably pressure holding is fixed on defining flange 131 by rotor 20.
It is understood that in order to ensure the fastening effect of pre-load nut, pre-load nut is set the more to turn the more tight when rotating shaft 10 rotates, this is solid
The rotation direction for determining the externally threaded rotating shaft 10 in section 120 is opposite.
The utility model also proposes a kind of motor, and the motor includes rotor assembly, the concrete structure reference of the rotor assembly
Above-described embodiment, because this motor employs whole technical schemes of above-mentioned all embodiments, therefore at least there is above-mentioned implementation
All beneficial effects caused by the technical scheme of example, this is no longer going to repeat them.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model,
Every equivalent structure change under inventive concept of the present utility model, made using the utility model specification and accompanying drawing content
Change, or directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
