Abstract
The utility model provides a structure of electric motor rotor ventilation frid, includes rotor punching, rotor duct spacer and locating hole, press the locating hole at the rotor punching upper punch, on rotor duct spacer's the spine embedding rotor punching. The beneficial effects of the utility model are that: do not need to manufacture alone the rotor end plate, do not need antitrochanter duct spacer to carry out spot welding, reduced man -hour, rotor duct spacer is reliable with the rotor punching location of taking the locating hole, and motor rotation number is big, when the temperature is high, and rotor duct spacer can not thrown away.
Description
Technical field
The present invention relates to rotor manufacturing process field, especially a kind of structure of rotor ventilation channel plate.
Background technology
In prior art, the structure of rotor ventilation frid is all formed by rotor end plates and the spot welding of rotor ventilation slotted vane, integrally uses when rotor core laminates.This structure, need to make separately the thick rotor end plates of 1mm, the flute profile of stamping rotor end plate again, processes loaded down with trivial details.In, temperature large at motor speed is high, easily cause rotor ventilation slotted vane sealing-off, throw away, and rotor ventilation slotted vane shelters from the ventilation hole of rotor, increases axial windage, have impact on wind path.
Summary of the invention
Technical problem to be solved by this invention is, a kind of structure of rotor ventilation channel plate rational in infrastructure is provided, can make rotor ventilation slotted vane can not large because of motor speed, temperature is high and sealing-off throws away, and do not need to use rotor end plates, do not need to carry out spot welding, simplify the processing and manufacturing in production.
For solving the problems of the technologies described above, the invention provides a kind of structure of rotor ventilation channel plate, comprising rotor punching, rotor ventilation slotted vane and location hole; At rotor punching upper punch pressure location hole, the protruding parts of rotor ventilation slotted vane embeds on rotor punching.
Preferably, the thickness of rotor punching is 0.5mm, and 10 rotor punchings overlap together.
Preferably, the width of location hole and length are 3.2mm*15.2mm.
Preferably, vent segment protruding parts width and length are 3mm*15mm, and protrusion height is 4.8mm.
Beneficial effect of the present invention is: do not need to manufacture rotor end plates separately, does not need to carry out spot welding to rotor ventilation slotted vane, decreases man-hour; Rotor ventilation slotted vane locate reliably with the rotor punching of band location hole, motor speed greatly, temperature height time, rotor ventilation slotted vane can not be thrown out of.

Embodiment
As shown in Fig. 5,6,7,8, a kind of structure of rotor ventilation channel plate, on the rotor punching of 10 0.5mm thickness, punching press width and length are the location hole of 3.2mm*15.2mm, and rotor ventilation slotted vane protruding parts width and length are 3mm*15mm, and protrusion height is 4.8mm.When rotor core is laminated to rotor ventilation road, first the rotor punching of 10 band location holes is laminated neatly, then by the rotor punching of the protruding parts embedded location hole of rotor ventilation slotted vane, then place the stator punching without location hole and continue to laminate.
Although the present invention illustrates with regard to preferred implementation and describes, only it will be understood by those of skill in the art that otherwise exceed claim limited range of the present invention, variations and modifications can be carried out to the present invention.
