Specific embodiment

In order to overcome the shortcoming of prior art, the present invention provides a kind of motor rotor construction for compressor, including is put down under rotor Lamination 4 is balanced on weighing apparatus block lamination 1, rotor core 2 and rotor.

Balance weight lamination 1 under lamination 4 and rotor is balanced on rotor to be arranged at rotor core about 2 both sides；Balanced under rotor Block lamination 1, rotor core 2 are fixedly connected with balance lamination 4 on rotor by rivet 3.

During making, rotor punching is first by laminating to form rotor core 2；Requirement choosing respectively according to counterweight size is corresponding Second balance weight punching 1-2 of quantity is combined superposition, is finally sealed with 1 the first balance weight punching 1-1, laminates to be formed and turns Balance weight lamination 4 on the lower balance weight lamination 1 of son and rotor；Finally by balance weight lamination 1 and rotor under rotor core 2, rotor Connected by rivet long 3 between the three of balance weight lamination 4 and form rotor.

Refer to shown in Fig. 2, the first balance weight punching 1-1 is annular, and the riveting for being arranged with and being passed through for rivet 3 is opened thereon Nail 1-1-1.Symmetrical structure centered on first balance weight punching 1-1.

Refer to shown in Fig. 3, the second balance weight punching 1-2 is identical with the first balance weight punching 1-1, generally annular, The rivet hole passed through for rivet 3 is equally offered thereon；Internal engraved structure 1- is provided with one side of something of second balance weight punching 1-2 2-1, forms non-centrosymmetrical eccentric structure.

Refer to shown in Fig. 4, similar, another motor rotor construction for compressor, including balance weight lamination 11 under rotor, Balance weight lamination 15 and rivet 16 on rotor core casting casting die 13, rotor.

After rotor punching is laminated, formed with upper aluminium (copper) end ring 14 and lower aluminium (copper) end ring 12 by cast aluminium or cast copper Rotor core casts casting die 13；Second balance weight punching 11-2 of the selected respective amount of requirement respectively according to counterweight size carries out group Superposition is closed, is finally sealed with 1 the first balance weight punching 11-1, laminate to form under rotor balance on balance weight lamination 11 and rotor Block lamination 15；Balance weight lamination 15 is connected to rotor core and casts casting die by rivet 16 on balance weight lamination 11 and rotor under rotor On 13, rotor is formed.
