When plate heat expands, V-arrangement angle becomes larger, and stress is released in deformation process.
Further, the gusset is S-shaped on cross section.When gusset contract on cooling, gusset is to two recess portions of S-shaped
Side deforms；And when gusset heat expands, gusset is deformed to two protrusions side of S-shaped, and stress is released in deformation process
In.
Preferably, the gusset is non-linear structure on longitudinal section.The deformation direction of gusset is axial, deformation
Generated stress is released in deformation process.
Further, the gusset is arc on longitudinal section.When gusset contract on cooling, gusset is to the recess portion one of arc
Side deforms；And when gusset heat expands, gusset is deformed to the protrusion side of arc, and stress is released in deformation process.
Further, the gusset is V-arrangement on longitudinal section.When gusset contract on cooling, V-arrangement angle becomes smaller；And work as muscle
When plate heat expands, V-arrangement angle becomes larger, and stress is released in deformation process.
Further, the gusset is S-shaped on longitudinal section.When gusset contract on cooling, gusset is to two recess portions of S-shaped
Side deforms；And when gusset heat expands, gusset is deformed to two protrusions side of S-shaped, and stress is released in deformation process
In.
Preferably, outer hub and interior hub are further included；The magnet is set in the outside of the outer hub, the gusset
One end is connect with the inner wall of the outer hub；The interior hub sleeve is located at the outside of the shaft, the other end of the gusset with it is described
The outer wall connection of interior hub；The gusset, the outer hub and the interior hub integrated injection molding form.Magnet inner surface is smooth, if directly
It connects and is connected with each other with gusset, lead to structure very built on the sand.By the outer hub being embedded in inside magnet, magnet and gusset are connected
It connects, structural strength is made to disclosure satisfy that requirement.Shaft surface is smooth, if be directly connected with each other with gusset, leads to structure very not
It is firm.By the interior hub being set in outside shaft, by shaft and link of boards, structural strength is made to disclosure satisfy that requirement.It is being molded
In the process, gusset, outer hub and interior hub are moulded between shaft and magnet together.Mold forming technique is ripe, automated production
It is more efficient.
In conclusion by adopting the above-described technical solution, compared with the prior art, the beneficial effects of the invention are as follows：This
Invention, instead of existing linear type reinforcing plate structure, changes injection molded magnets rotor assembly in heat using nonlinear type reinforcing plate structure
Impact direction during swollen shrinkage reduces the stress of magnet, so as to achieve the purpose that eliminate magnet crackle.Solves current linear type
The defects of gusset injection rotor assembly can not use under the big environment of temperature change.In addition, gusset uses plastic material, and adopt
Magnet, shaft, gusset etc. are molded into an overall structure with Shooting Technique, one-pass molding, production efficiency is high.In recent years,
Rotor assembly develops rapidly, and is widely used in various electrical equipments.Produce in enormous quantities, simultaneously this requires one kind is suitable
Cost is greatly reduced, quality also needs the magnet rotor packaging scheme to improve a lot.The present invention uses injection molded magnets rotor assembly
Mode, be disclosure satisfy that this requirement preferred plan.
