Description
Technical field
Magneto is the utility model is related to, more particularly to a kind of novel rotor pressure plate structure.
Background technology
With the promotion and application of the development of magneto, particularly magneto in electric automobile field, magneto
Because power density is big, the advantages that efficiency high and by highly recognition, it is widely used in electric automobile field.Because magneto
Be a fast-developing in recent years industry, many techniques have much room for improvement, such as the processing of rotor.
Electric motor of automobile power is relatively large, and performance requirement is high, and corresponding rotor core is folded thick larger, in order to reduce temperature rise,
Reduce eddy-current loss, rotor punching fold thickness must do it is thin, in order to prevent iron core fin and every magnetic, generally require at iron core both ends
Plus rotor press plate.Existing rotor press plate is more using cast aluminium pressing plate or machining stainless steel platen：Cast aluminium pressing plate needs to mold,
And thickness is thicker；Machining stainless steel platen intensity difference is easily deformed, it is necessary to be welded in surrounding, proof strength.
The shortcomings that above-mentioned technology is processed complex, and process is more, because the process of welding is more, it is necessary to remove resilience stress, week
Phase is grown, and the deformation size welded greatly, it is necessary to stay larger allowance, makes material and high processing costs in processing, meanwhile,
Rotor weight and rotary inertia can not effectively be mitigated, and adjustment amount is big during dynamic balancing.
Prior art includes：
1. two ends of rotor adds the cast aluminium pressing plate of two annulars, central shaft hole is interference fitted by hot jacket and axle, Ci Zhongfang
Case needs to preheat iron core, and time length, cast aluminium sheet material is thicker, and material cost is high, and there is also certain safety to operation for high temperature
Hidden danger.
2. with machining stainless steel annular steel plate, the welding of rotor surrounding, axis hole centre hot jacket is interference fitted with axle.It is such a
Scheme stainless steel plate flexible type, surrounding need to weld, intermediate demand hot jacket, complex process, and cost is high, and efficiency is low.
In summary, have the defects of prior art：
1st, cost is high, and the big cost of cast aluminium thickness of compressive plate is high, and machine adds armor plate strength low, and processing charges is high；
2nd, pressing plate installation procedure is complicated, and rotor needs to heat, welded, destressing after welding, cycle length, and efficiency is low；
3rd, heat and weld and high are required to human users, part easily causes scald to human users after heating, welds to work
People, which operates, requires high, including weld size, welding position etc. are difficult to ensure that uniformity.
Utility model content
The purpose of the utility model is：To overcome above-mentioned prior art defect, the utility model provides a kind of novel rotor pressure

Circumference is provided with the face of cylinder with this body by integral forming of pressing plate and vertically upward, and rotor shaft passes therethrough；The face of cylinder upper end
It is raised that the sleeving and riveting coordinated with rotor shaft by sleeving and riveting technique is provided with provided with flanging structure, in the middle part of the face of cylinder, rotor shaft pair
Reserve sleeving and riveting neck in the position answered.
Preferably, the pressing plate body upper surface is provided with protruding reinforcing rib.
Preferably, when the pressing plate body assembles with rotor, increase is every magnetic thin plate between rotor core.
Preferably, the pressing plate body makes to be formed using sheet metal component.
Preferably, pressing plate body is cold-pressed sleeving and riveting position in the cold state during the pressing plate body installation.
The utility model has the advantages that：
1. the utility model is installed using the face of cylinder with rotor shaft by sleeving and riveting respective outer side edges, can be in the cold state
Directly it is pressed, is coordinated by sleeving and riveting tongue and groove and fixed, simplifies installation procedure, efficiency high, the production of suitable amount metaplasia；
2. for scheme of the present utility model compared to heating and welding, safety coefficient is higher, relative to human users' Capability Requirement
It is low；
3. the utility model uses sheet metal component processing technology, parts easy-formation, material walls thickness, it is minimum can be with 0.5mm
Left and right, and suitable amount metaplasia is produced, and cost is low and can reduce rotor weight and dynamic balancing.
