Abstract

The invention relates to a copper-bar rotor structure of a three-phase asynchronous motor, comprising copper end rings, copper conducting bars, rotor ventilating duct plates, rotor sheets, rotor iron core keys, rotor clamping rings, iron core locking keys, wherein the multiple rotor ventilating duct plates and the rotor sheets are sleeved on a rotor spindle in a laminated mode; the rotor ventilating duct plates and the rotor sheets are fixed with the rotor spindle by the rotor iron core keys; two ends of each rotor iron core key are fixed on the rotor spindle by the rotor clamping rings sleeved on the rotor spindle; the copper conducting bars are inserted into iron core ducts which are formed by the lamination of the rotor ventilating duct plates and the rotor sheets; and two ends of each copper conducting bar are welded with the copper end rings. The copper-bar rotor structure in the invention is reasonable and compact and convenient to operate as well as install and maintain, and has the advantages of high reliability, low mould cost, simple technology, short processing period and good manufacturability.

Description

A kind of threephase asynchronous copper bar rotor structure
Technical field
The present invention relates to the copper bar rotor structure of a kind of motor rotor structure, particularly a kind of medium-and-large-sized threephase asynchronous.
Background technology
At present, electromechanics trade is fast-developing, and the structure of motor is also in continuous variation, add enterprise product and will constantly promote reliability, the efficient of customer requirement also will constantly improve, customer requirement constantly shortens motor delivery date, processing and fabricating is also simple and clear, and existing cast-aluminum rotor will be opened Cast Aluminum Dies up and down, and the fabrication cycle of Cast Aluminum Dies is long, and the manufacturing cost of mould is also higher, and the resistivity of aluminium (0.0434) wants big many than the resistivity (0.0217) of copper, the loss of nature motor is also bigger, and the operating efficiency of motor is difficult to improve naturally.As shown in Figure 1, the cast-aluminum rotor structure is that aluminium end ring 11, cast aluminium sliver 12, rotor punching 13, rotor ventilation frid 14 are placed on the moulds of industrial equipment that design in sequence, aluminium ingot is fused into aluminium liquid, aluminium end ring 11, cast aluminium sliver 12, rotor punching 13, rotor ventilation frid 14 are poured into an integral body, be inserted on the axle 8 of rotor together, form the rotor of a cast aluminium structure.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of threephase asynchronous copper bar rotor structure is provided, is the copper bar rotor of the high efficient, high pressure threephase asynchronous of a kind of efficient height, good reliability.
According to technical scheme provided by the invention, the copper bar rotor structure of described threephase asynchronous comprises: the copper end ring, the copper bar sliver, the rotor ventilation frid, rotor punching, the rotor core key, rotor pressing ring, locking key unshakable in one's determination, multi-disc rotor ventilation frid and rotor punching laminate on the axle that is enclosed within rotor, fix by the rotor core key between the axle of described rotor ventilation frid and rotor punching and rotor, rotor core key two ends are fixed on the axle of described rotor by the rotor pressing ring on the axle that is enclosed within rotor, described copper bar sliver is inserted in the rotor ventilation frid and rotor punching laminates in the flute profile unshakable in one's determination of formation, each copper bar sliver two ends soldering copper end ring.
The outside of described rotor pressing ring is locked on the axle of rotor by locking key unshakable in one's determination.
Each parts pack in sequence design fits good the axle on, rotor ventilation frid and rotor punching laminate in sequence.
Advantage of the present invention is: rational in infrastructure, reliability is high, compact, die cost is low, technology is simple, easy to operate, process-cycle is short, good manufacturability is convenient for installation and maintenance.
Description of drawings
Fig. 1 is a cast-aluminum rotor structural representation in the prior art.
Fig. 2 is a copper bar rotor structure schematic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 2, copper bar rotor structure of the present invention comprises: copper end ring 1, copper bar sliver 2, rotor ventilation frid 3, rotor punching 4, rotor core key 5, rotor pressing ring 6, locking key 7 unshakable in one's determination, multi-disc rotor ventilation frid 3 and rotor punching 4 laminate on the axle 8 that is enclosed within rotor, fixing between the axle 8 of described rotor ventilation frid 3 and rotor punching 4 and rotor by rotor core key 5, rotor core key 5 two ends are fixed on the axle 8 of described rotor by the rotor pressing ring 6 on the axle 8 that is enclosed within rotor, described copper bar sliver 2 is inserted in rotor ventilation frid 3 and rotor punching 4 laminates in the flute profile unshakable in one's determination of formation, each copper bar sliver 2 two ends soldering copper end ring 1.The outside of described rotor pressing ring 6 is locked on the axle 8 of rotor by locking key 7 unshakable in one's determination.
During assembling, rotor core key 5 is contained on the axle 8 of rotor, be inserted in rotor pressing ring 6 again, laminate in sequence again and change rotor ventilation frid 3 and rotor punching 4 over to, compress with certain pressure then, reinstall rotor pressing ring 6, lock with locking key 7 unshakable in one's determination again, go into copper bar sliver 2 in the flute profile interpolation unshakable in one's determination that laminates then, soldering copper end ring 1 on copper bar sliver 2 is so just formed efficient copper bar rotor at last.Adopt special welding procedure between rotor end ring and the copper bar sliver.
