Abstract

The utility model relates to a rotor end part structure for a driving motor of a main helium fan. The rotor end part structure consists of a guard ring, an end ring, a non-driving-end clamping ring, a shaft, a driving-end clamping ring, a rotor core, a copper bar, protrusions, a driving-end radial ventilating slot, an axial venthole, a non-driving-end radial ventilating slot and a guard ring radial venthole, wherein the guard ring is connected with the shaft; the outer ring of the guard ring is connected with both the end ring and the copper bar in an interference fit manner; the end ring and the copper bar are welded together; the protrusions are arranged on two sides of the end ring and respectively connected with the guard ring and the non-driving-end clamping ring, as well as the driving-end clamping ring; the rotor core is mounted on the shaft; the driving-end radial ventilating slot is formed on the driving-end clamping ring; the axial venthole and the non-driving-end radial ventilating slot are formed on the non-driving-end clamping ring; and the radial venthole is formed on the guard ring. The rotor end part structure has the advantages of simple structure, reasonable design, good heat dissipation and ventilation and cooling effects, and ensures that the internal structure of the motor is prevented from damage because the motor has low probability of failures, thereby prolonging the service life of the motor.

Description

The Helium fan drive motors is used rotor terminal structure
Technical field: the utility model relates to a kind of Helium fan drive motors and uses rotor terminal structure.
Background technology: at present, the rotor terminal structure of existing common vertical machine can not satisfy power 4500KW, the working condition requirement of rotating speed 4000r/min in the HTGR nuclear power station; The blower fan chamber and the motor cavity of motor communicate, and the temperature in blower fan chamber is 250 ℃, and common electric machine can't use under the operating mode of this temperature; Draught fan impeller directly is connected with axle, and is higher through the thermal power that axle conducts, and dispels the heat, the ventilation cooling effect is poor; The motor easy fault makes internal structure of motor cause damage, influences the useful life of motor; Cause nuclear reactor unplanned shutdown number of times to increase, cause enormous economic loss.
Summary of the invention: the purpose of the utility model is to overcome above-mentioned shortcoming; Provide a kind of Helium fan drive motors to use rotor terminal structure; It has mainly solved existing common vertical machine heat radiation, the ventilation cooling effect is poor; Satisfied not power 4500KW, the problems such as working condition requirement of rotating speed 4000r/min in the HTGR nuclear power station.The purpose of the utility model is achieved in that the Helium fan drive motors is made up of: retaining ring, end ring, non-shaft stretching end trim ring, axle, shaft extension end trim ring, rotor core, copper bar, convexity, shaft extension end radial ventilation groove, axial ventilation hole, non-shaft stretching end radial ventilation groove, retaining ring radial ventilation hole with rotor terminal structure.Retaining ring adopts interference fit to be connected with axle, and the retaining ring outer ring is connected with end ring and copper bar interference fit, and end ring and copper bar weld together; The both sides of end ring are provided with convexity; Convexity is connected with non-shaft stretching end trim ring and shaft extension end trim ring with retaining ring respectively, and rotor core is installed on the axle, has shaft extension end radial ventilation groove on the shaft extension end trim ring; Have axial ventilation hole and non-shaft stretching end radial ventilation groove on the non-shaft stretching end trim ring, have the radial ventilation hole on the retaining ring.This product structure is simple, and is reasonable in design, owing on the retaining ring of rotor tip, be provided with ventilation hole; Be provided with convexity between retaining ring and the end ring, contact has space, end ring to be difficult for causing torsional deformation; Have the radial ventilation groove on the trim ring of shaft extension end, have axial ventilation hole and radial ventilation groove on the non-shaft stretching end trim ring, heat radiation, ventilation, good cooling results; Motor is easy fault not, causes internal structure of motor to damage, and has prolonged the useful life of motor; Can not cause the increase of nuclear reactor unplanned shutdown number of times because of the fault of Helium fan, reduce economic loss.
