Abstract
The invention relates to a motor rotor using an insert copper strip to replace an aluminum row for a refrigerating compressor, comprising an upper end ring, a lower end ring and a copper guiding strip, wherein the upper end ring and the lower end ring are provided with slots which are matched with the copper guiding strip, and the copper guiding strip is inserted into the slots of the upper end ring and the lower end ring and is connected with the upper end ring and the lower end ring to form the motor rotor. Compared with the prior art, by adopting a copper strip riveting mode to replace an aluminum casting mode, the invention saves energy, reduces emissions, reduces rotor loss by adopting the copper guiding strip and increases motor performance.
Description
Technical field
The present invention relates to a kind of rotor, especially relate to a kind of refrigerant compressor rotor with plug-in type copper bar substitution of Al row.
Background technology
Existing squirrel-cage single-phase asynchronous motor rotor adopts aluminum process more, complex process and and power consumption.In addition, aluminium resistivity is higher, and is subjected to the aluminium ingot impurity effect easily, makes rotor loss big, and electric efficiency is low.This " characteristic " of cast-aluminum rotor become one of bottleneck of restriction electric efficiency raising.
Summary of the invention
Purpose of the present invention is exactly the refrigerant compressor rotor that provides a kind of energy-saving and emission-reduction in order to overcome the defective that above-mentioned prior art exists, reduces rotor loss, improves motor performance, arranges with plug-in type copper bar substitution of Al.
Purpose of the present invention can be achieved through the following technical solutions: a kind of refrigerant compressor rotor with plug-in type copper bar substitution of Al row, it is characterized in that, comprise top ring, lower loop and copper sliver, described top ring and lower loop are provided with the slotted eye that is complementary with the copper sliver, the copper sliver is inserted in the slotted eye of top ring and lower loop, the copper sliver is connected with lower loop with top ring and promptly constitutes rotor.
Described copper sliver adopts rivet, hot jacket or welding with being connected of top ring and lower loop.
Rheo-die-casting moulding or the moulding of copper sheet riveted joint mode are adopted in the manufacturing of described top ring and lower loop.
Slotted eye on described top ring and the lower loop is the open slot or the groove of remaining silent, and the flute profile of slotted eye can be parallel teeth, parallel slot, dovetail groove or double-cage rotor groove, and top ring and lower loop need and can exchange with assembling.
The shape of cross section of described copper sliver can be circle, triangle, square or polygon.
Compared with prior art, rotor copper sliver of the present invention and end ring employing groove cooperation up and down, the copper sliver inserts in the upper and lower side groove hole, after assembling is finished, can select assembly technology by riveting intensity, copper sliver and upper and lower side annular shape, size be in conjunction with the motor requirement, further refinement.The rotor balance weight, when the manufacturing end ring, can rheo-die-casting moulding or other connection, the alternative cast aluminium of employing copper bar riveted joint mode, energy-saving and emission-reduction, employing copper sliver, reduction rotor loss, the raising motor performance of riveting.
