The manufacturing process of this rotor is roughly: 1, prefabricated rotor punching with aluminium hand-hole and endoporus; 2, rotor punching is placed the mould internal layer build up rotor core and contain mould, rotor core has the aluminium hand-hole; 3, in mould, inject aluminium liquid, make the aluminium hand-hole of the full rotor core of aluminium liquid filling form secondary conductor aluminium and cast lower loop at the two ends of rotor core formation aluminium casting top ring and aluminium; 4, obtain rotor after the die sinking.
For the motor that makes freezer compressor has heat sinking function when working, someone designs the rotor with heat emission fan, as shown in Figure 2, namely is cast with blade 4 at aluminium casting top ring 11.Its objective is that the heat emission fan of utilizing rotor promotes the gas flow of compressor inside, the heat that motor is produced is delivered on the metal shell and by metal shell as early as possible outwards distributes, and reaches the effect that reduces the compressor internal temperature.
The existing this way that directly casts out heat emission fan at rotor, although have the characteristics of simple in structure and easy manufacturing, but the rotor for different size then will be designed respectively different mfg. moulding dies, even the identical rotor of specification also will be according to different power designs different heat emission fan (adopting different mfg. moulding dies to realize), therefore the problem of bringing is that the mfg. moulding die of rotor increases, and manufacturing cost increases.Simultaneously, because aluminum intensity is low, its radiator shutter need to be done very thickly, seems heavy.
Summary of the invention
The objective of the invention is to propose a kind of freezer compressor rotor, it is installed in heat emission fan on the general rotor, has advantages of highly versatile, good heat dissipation effect and low cost of manufacture.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of freezer compressor rotor, comprise rotor subject, described rotor subject is by rotor core, aluminium casting top ring, aluminium casting lower loop and secondary conductor aluminium are combined into, rotor core is laminated by some silicon steel sheets and forms, rotor core has the aluminium hand-hole, aluminium casting top ring and aluminium casting lower loop lay respectively at the two ends of rotor core, secondary conductor aluminium is filled the aluminium hand-hole of full rotor core aluminium is cast top ring, rotor core and aluminium casting lower loop connect into overall structure, rotor core, aluminium casting top ring and aluminium casting lower loop have respectively coaxial iron core endoporus, top ring endoporus and lower loop endoporus;
The end face of described aluminium casting top ring is provided with at least 2 riveting columns, heat emission fan has the ring plate of installation and at least 2 blades, the blade disjunctor evenly is located at and is installed on the ring plate, the riveting column of the corresponding aluminium casting of described installation ring plate top ring has the perforation of the ring plate of installation, have isometrical mesopore corresponding to the top ring endoporus, heat emission fan is fixedly connected on the aluminium casting top ring by ring plate perforation and riveting column are installed.
Prioritization scheme, described blade are arc-like sheet.
Among the present invention, riveting column integrated die-casting moulding in the manufacture process of rotor on the aluminium casting top ring, heat emission fan is then made separately in addition, can make as required various heat emission fan (such as two leaves fan, three leaves fan, five leaf fans etc.), when needing heat emission fan is fixedly installed on the aluminium casting top ring by ring plate perforation and riveting column are installed.
The present invention has following outstanding substantive distinguishing features and significant progressive:
1, heat emission fan is equivalent to a centrifugal fan among the present invention, in with the rotor rotation process, can produce centrifugal force, hot-air around the rotor is flowed and away from rotor, have good heat-sinking capability, can effectively avoid the temperature of rotor to raise, guarantee the normal operation of motor;
2, can be according to the performance need of different freezer compressors, apolegamy has the heat emission fan of varying number and difformity blade installs, and has the characteristics simple, highly versatile of installing;
3, the heat emission fan among the present invention can be that plastic material can be iron and steel material quality also, and the cost of material is low, and profile is merrily and lightheartedly small and exquisite;
4, the manufacturing process of rotor of the present invention is ripe, simple, and riveting column and heat emission fan on the aluminium casting top ring are lightweight, can not increase the running burden of rotor, can not affect motor runnability.
