Present invention seek to address that the defects of known technology, there is provided a kind of cover board of combined rotor, by being spelled with outer ring, axle sleeve
After welding equipment connects combination, a kind of rotor of high-speed electric expreess locomotive is formed, by composite assembly, each component can be allowed to obtain higher processing essence
The yield of degree and higher, compared with the technology acuracy for not only possessing higher than 2007201077114., and cost of manufacture is
2007201077114. 1/3rd of patented technology.
The cover board of high-speed motor of electric vehicle combined rotor of the present invention, applied to the combined rotor of high-speed motor of electric vehicle, its
It is characterized in that cover plate central is formed with centre bore, lower section is formed with step, and the centre bore radially outer of cover board is formed with decile geometric form hole,
Cover board mirror alignment is connected firmly by step and outer ring minor diameter fit, cover board with outer ring welding, and the centre bore of cover board and axle sleeve welding are solid
Connection.
In a kind of form, the centre bore of upper and lower cover plates is concentric.
Inner hole of shaft sleeve is formed with Xiao's pilot trench or spline housing, and axle sleeve makes oblique angle, axle sleeve outside two end table planar radials up and down
Welding connects firmly upper and lower cover plates centre bore.
In a kind of form, by upper and lower cover plates mirror alignment, step and the outer ring minor diameter fit of cover board, cover board is welded with outer ring
Connect firmly.
In a kind of form, the centre bore radially outer of cover board is formed with decile geometric form hole, and decile geometric form hole can mitigate
Rotor weight, lifts motor speed.
Further, decile geometric form hole can be used as, in air discharging and radiating path in motor room, reducing motor temperature rise, lift motor
Efficiency.
In a kind of form, cover board is made by low-carbon steel material.
Further, the mild steel trade mark is A3, phosphorus content 0.08% or 0.10% be preferred.
The cover board of high-speed motor of electric vehicle combined rotor of the present invention, in motor assembling, cover board is the crucial portion in rotor
Part, the precision height of cover board, will directly affect electric vehicle motor product quality, or even be related to lifting and the motor of motor speed
Temperature rise.Connected firmly outside cover board with outer ring welding, cover board internal diameter is connected firmly with axle sleeve welding, after cover board, axle sleeve, outer ring are combined integrated
High speed rotor of motor is formed, during assembling, motor shaft passes through inner hole of shaft sleeve be connected with cover central hole and makees directly to extending and upper and lower side
Lid coordinates, and in rotor outer ring perimeter surface mounting magnetic steel, the screw hole of outer ring is connected firmly by screw.It is of the invention assembled with each component combination,
Flowing water batch making can be carried out by equipment, such as outer ring, the inside/outside diameter size of axle sleeve, it can be one on extrusion equipment
Secondary property precise forming, similar to the seamless steel pipe of in the market, by composite assembly, can allow each component to obtain higher processing essence
The yield of degree and higher, compared with the technology acuracy for not only possessing higher than 2007201077114., and cost of manufacture is
2007201077114. 1/3rd of patented technology.
