Abstract
The utility model belongs to an end structure of the high speed cage asynchronous motor rotor. The present end structure of the rotor constantly generates the accident that a conduct bar is broken in operation so as to directly affect the accomplishment of the producing task and cause the severely economic loss. The end structure of the rotor of the device aims at the disadvantage to improve the structure, the conduct bar of the end of the common rotor is lengthened, and the inner and outer side positions of the end ring are exchanged, and the connecting section area of the conduct bar and the end ring is increased, and a protecting ring is thinned and directly protects the conduct bar, and then the end structure of the rotor is formed. The structure ensures the long-term safe operation of the conduct bar according to the practice.
Description
The present invention is a kind of new structure of the rotor tip that is used to design or transform the high-speed cage asynchronous motor.Use for departments such as factory, mine, power plant, oil field and pipeline roads.
The known generally rotor terminal structure of the high-speed cage asynchronous motor of operation is (referring to Big Motor Reserch Academy, Ha Erbin City's " big motor technology " in 1982 third phase " about the discussion of high-speed high capacity squirrel cage induction motor rotor tip intensity " literary composition, 15 pages of Fig. 2), every sliver stretches out 34 millimeters places of rotor core, weld with single cross section dress with end ring, behind the hot jacket retaining ring, assembling prevents the bolt of axial motion.This structure since sliver to stretch out rotor core length too short, the single cross section that is connected of sliver and end ring is too little, and retaining ring direct reason such as protection sliver not, makes structural design unreasonable, in service in the commissure generation up to 5000 kilograms/cm
2Rotor tip bar failure accident often takes place in above stress.Cause the direct economic loss of units up to a million for departments such as factory, mine, power plant, oil field and pipeline road, have influence on the finishing of the production schedule of these departments.
Task of the present invention is to improve at the shortcoming on the said structure, in order to eliminate rotor tip bar failure accident, the often requirement of starting or long-time running of high-speed cage asynchronous motor is satisfied in design or transform a kind of new structure of the rotor tip that can guarantee safe operation.
The said new structure of the rotor tip of the present invention is illustrated in conjunction with the accompanying drawings.About increasing the elongation of rotor tip sliver, be that applicating modern times technology is reached a conclusion as calculated, with extension elongation by 34 millimeters lengthenings at 60 to 140 millimeters, (big capacity, major diameter are got big value.) according to the disconnected bar accident analysis of known high-speed cage asynchronous motor, also confirmed the short more bar accident of breaking that is easy to generate more of sliver extension elongation.Known end ring rigging position is designed to the assembling that interior outer fix is exchanged, so as to adapting to the needs after sliver extends.Every sliver is connected with end ring by the dress weldering of single cross section and is designed to two dress weldering cross sections in length and breadth, has reduced nearly one times of the stress of critical section.Retaining ring in the said new structure of the rotor tip of the present invention is by the calculating of modern technologies, and the monolateral effective thickness of retaining ring is thinned to 10 to 20 millimeters, and retaining ring belongs to non magnetic rare metal, and the attenuate retaining ring can reduce motor cost; Retaining ring in the said new structure of the rotor tip of the present invention is designed to directly protect sliver.
The new structure of the rotor tip that the present invention is illustrated, sliver are to make with the red copper that draws moulding, and end ring is to use the red copper forging molding, and retaining ring is to make with the non-magnetic high strength alloy steel.The present invention is the new construction that is used to design or transform rotor tip, have rational in infrastructure, make simply, mounting or dismounting are convenient, low cost and other advantages, and can guarantee the long-term safety operation.
The new structure of the rotor tip of the said high-speed cage asynchronous motor of the present invention is applicable to 1000 kilowatts to 8000 kilowatts scopes.
Accompanying drawing is a new structure of the rotor tip embodiment of the present invention.
Description of drawings:
1. rotor core; 2. pressing plate; 3. sliver; 4. retaining ring; 5. end ring;
Claims (2)
1, a kind of new structure of the rotor tip that is used to design or transform the high-speed cage asynchronous motor has: rotor core [1], pressing plate [2], sliver [3], end ring [5] and the retaining ring [4] that is used for fixing, protects sliver or end ring, sliver be by end ring short circuit in addition,
It is characterized in that:
The elongation of rotor tip sliver is at 60 to 140 millimeters, and outer fix is exchanged in the end ring.Two dresses weld cross sections to every sliver with having being connected of end ring in length and breadth, and the monolateral effective thickness of retaining ring is thinned to 10 to 20 millimeters, and retaining ring is directly protected sliver, has formed new structure of the rotor tip.
2, a kind of according to the said new structure of the rotor tip of claim 1, it is characterized in that said sliver is to make with the red copper that draws moulding, end ring is to use the red copper forging molding, retaining ring is made with non magnetic high strength alloy steel.
