Abstract
The utility model relates to a synchronous machine rotor support structure, electric motor rotor is the salient pole structure, divide into magnetic pole (9), rotor support, pivot (10), rotor support comprises wheel hub (1), panel (2), yoke ring (3), panel (2) and yoke ring (3) suit and welded fastening, the yoke ring has through-hole (4), magnetic pole (9) lower part has the screw hole, bolt (5) suit lock washer (6) and pass through-hole (4) and join in marriage with magnetic pole (9) lower part screw hole and join in marriage the dress, yoke ring (3) inboard has tang (7) and annular (8). The utility model discloses the cooperation form that web and yoke circle adopted the shrink fit to combine with the welding has reduced the manufacturing degree of difficulty than whole casting under the prerequisite of guaranteeing operational reliability, and the single face welding reduces the welding volume and has reduced the welding requirement, more can satisfy the requirement of transmission torque on the same overall dimension. An annular groove is processed on the inner side of the magnetic yoke ring and used for tightly clamping an outer tongue locking washer, so that the magnetic pole bolt is locked.
Description
Technical Field
The utility model relates to a synchronous machine rotor support structure.
Background
The motor rotor support is an intermediate part which integrates the magnetic pole and the rotating shaft, and during normal operation, the rotor support bears the action of torque, the gravity moment of the magnetic pole and the magnetic yoke, the centrifugal force of the rotor support and the thermal keying radial cooperation force, and the support and the shaft are in a thermal sleeve cooperation structure and also bear the action of the thermal sleeve cooperation force of the support and the shaft. Therefore, the rotor support is an important part with complex stress, and the rotor support consists of a hub, a web and a yoke ring, is generally formed by assembling and welding a forged steel yoke ring, the hub and a steel plate, and can also be integrally cast. When a high-power synchronous motor is designed, the integrally cast rotor bracket is easy to have defects, the yield is not high, the welding requirement of the completely assembled and welded bracket is high, and the requirement of transmitting torque can not be met.
The invention content is as follows:
the utility model aims at providing a structure is reliable and be applied to the synchronous machine rotor support structure of high-power, multipolar number salient pole. The technical scheme of the utility model is that: a synchronous motor rotor support structure is characterized in that a motor rotor is of a salient pole structure and is divided into a magnetic pole (9), a rotor support and a rotating shaft (10), the rotor support is composed of a hub (1), a web (2) and a yoke ring (3), the web (2) and the yoke ring (3) are sleeved and welded and fixed, the yoke ring is provided with a through hole (4), the lower portion of the magnetic pole (9) is provided with a threaded hole, a bolt (5) is sleeved with a stop washer (6) and penetrates through the through hole (4) to be assembled with the threaded hole at the lower portion of the magnetic pole (9), and the inner side of the yoke ring (3) is provided with a spigot (7) and a ring.
The utility model discloses a theory of operation and advantage thereof:
the utility model discloses electric motor rotor is salient pole structure, and web (2) and yoke circle (3) add welded cooperation form for the heat jacket, and the yoke circle has through-hole (4), and yoke circle (3) inboard has tang (7) and annular (8) location and magnetic pole bolt lock washer (6) locking when being used for the web heat jacket. The rotor support is an assembly structure, a seam allowance is processed on the inner side of the magnetic yoke ring and used for positioning when a web is sleeved in a hot mode, the web is sleeved with the magnetic yoke ring in a hot mode after being welded with the hub, and the web and the magnetic yoke ring are welded on the other side in the hot mode after the hot sleeve is completed, so that the rotor support is formed. The matching form of the heat sleeve and the welding combination is adopted by the amplitude plate and the magnetic yoke ring, the manufacturing difficulty is reduced compared with the integral casting on the premise of ensuring the operation reliability, the welding quantity is reduced by single-side welding, the welding requirement is reduced, and the requirement of transmitting torque can be met on the same external dimension. An annular groove is processed on the inner side of the magnetic yoke ring and used for tightly clamping an outer tongue locking washer, so that the magnetic pole bolt is locked.
