It is mutually inclined setting with shaft, changes rotor assembly when expanding with heat and contract with cold, the stress direction of gusset reduces the stress of magnet, from
And achieve the purpose that avoid result in magnet crackle.
Preferably, the gusset circumferentially array distribution.When gusset contract on cooling, shaft occurs with magnet
Small axially opposing displacement, and the micro-displacement is not enough to reach the degree for influencing motor operating；And when gusset heat expands,
With magnet reversed small axially opposing displacement occurs for shaft.During axially opposing displacement occurs for shaft and magnet,
Some is released stress caused by deformation, to achieve the purpose that reduce gusset both ends stress.
Preferably, the gusset is circumferentially provided at least three.In order to which the structure for meeting rotor assembly is strong
Degree requires, and achievees the purpose that torsion pass, the quantity of gusset should at least be arranged three, and be preferred to be circumferentially uniformly distributed.
Preferably, further include outer hub, the magnet is set in the outside of the outer hub, the gusset with it is described outer
The inner wall of hub connects.Magnet inner surface is smooth, if be directly connected with each other with gusset, leads to structure very built on the sand.By embedding
Enter the outer hub inside magnet, by magnet and link of boards, structural strength is made to disclosure satisfy that requirement.
Preferably, further include interior hub, the interior hub sleeve is located at the outside of the shaft, the gusset with it is described interior
The outer wall of hub connects.Shaft surface is smooth, if be directly connected with each other with gusset, leads to structure very built on the sand.By being arranged
Shaft and link of boards are made structural strength disclosure satisfy that requirement by the interior hub outside shaft.
Preferably, the gusset, the outer hub and the interior hub integrated injection molding form.In sectional view, gusset 3,
The partition line of outer hub 4 and interior hub 5, hatching are only used for distinguishing each component.In injection moulding process, by gusset, outer hub and interior hub one
And it is moulded between shaft and magnet.Mold forming technique is ripe, and automated production is more efficient.
Preferably, the axial length of the shaft is more than the axial length of the interior hub.Shaft must reach stretching
Length outside motor casing, to achieve the purpose that export power.
Preferably, it is provided with the anti-channeling for preventing relative motion in the axial direction between the magnet and the outer hub
Portion.When driving, the injection molding body that is made of gusset, outer hub and interior hub must be kept fixed with magnet to be connect, and anti-channeling portion can then prevent
Only axial movement of the injection molding body relative to magnet.
Preferably, the anti-channeling portion includes the anti-channeling slot being arranged on the magnet inner wall, and is arranged in institute
State the anti-channeling ring on outer hub outer wall；The anti-channeling slot cooperates with the anti-channeling ring.This programme, which provides one kind, preventing axial alter
Dynamic structure, structure is reliable, and manufactures simple.
Preferably, the anti-channeling slot is the annular groove being arranged at the magnet both ends, the anti-channeling ring be with
The annular protrusion that the annular groove matches.Anti-channeling portion is arranged in the injection molding body and magnetic being made of gusset, outer hub and interior hub
The end of body is molded convenient for the production of mold, and will not be had an impact to the agent structure intensity of magnet.
In conclusion by adopting the above-described technical solution, compared with the prior art, the beneficial effects of the utility model
It is：The utility model changes injection molded magnets rotor set instead of existing vertical-type reinforcing plate structure, using apsacline reinforcing plate structure
Impact direction of the part when expanding with heat and contract with cold, reduces the stress of magnet, to achieve the purpose that eliminate magnet crackle.It solves at present
The defect that vertical-type gusset injection molding rotor assembly can not use under the big environment of temperature change.In addition, gusset uses plastics material
Matter, and magnet, shaft, gusset etc. are molded into an overall structure using Shooting Technique, one-pass molding, production efficiency are high.
In recent years, rotor assembly develops rapidly, and is widely used in various electrical equipments.This requires one kind to be suitble to high-volume raw
It produces while cost is greatly reduced, quality also needs the magnet rotor packaging scheme to improve a lot.The utility model uses injecting magnetic
The mode of body rotor assembly is to disclosure satisfy that this desired preferred plan.
