Abstract
The utility model discloses a rotor core pressing ring of an alternating-current traction motor. The rotor core pressing ring comprises a rotor core pressing ring body; at least 20 grooves are uniformly formed on the rotor core pressing ring body; and a blade is formed between two grooves. The rotor core pressing ring can press a rotor core on a rotor, improve the heat dissipation performance of the motor, reduce the temperature rise when the whole motor works and prolong the service life of the motor.
Description
Technical field
The utility model relates to a kind of iron core of rotor of motor trim ring, especially relates to a kind of AC traction motor rotor core trim ring.
Background technology
Because the volume of traction alternating current motor is restricted, inner free space is less, thereby some AC traction motor can not carry fan, and the trim ring that compresses iron core on the existing traction AC motor rotor does not have fan functionality, cause when work, temperature rise is often higher, influences the useful life of AC traction motor.
The utility model content
The purpose of this utility model is to provide a kind of AC traction motor rotor core trim ring that has the radiator fan function concurrently.
The purpose of this utility model is achieved through the following technical solutions: it comprises rotor core trim ring body, evenly is provided with at least 20 grooves on the described trim ring body, forms blade between two grooves.
The shape of cross section of described groove is preferably circular-arc.
The quantity of described groove is preferred 〉=and 30.
The size of described groove should be determined with standard cutter according to the diameter and the processing of trim ring.
The utility model both can be pressed to rotor core on the rotor, can improve the heat dispersion of motor again: when the blade on the trim ring body rotates with rotor rotation, bring air quantity can for the end ring and the sliver of rotor tip, and can be by sliver toward stator end diffusion wind, quicken inner toward outside heat transmission, thereby the temperature rise when reducing the work of whole motor prolongs useful life of motor.
Description of drawings
Fig. 1 is the rotor terminal structure schematic diagram of traction alternating current motor;
Fig. 2 is the structural representation of the utility model embodiment;
Fig. 3 is the A-A place cutaway view of Fig. 2.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to accompanying drawing, present embodiment comprises the trim ring body 3 that draws AC motor rotor, evenly is provided with 30 circular groove 3-1 of R50 size on the described trim ring body 3, forms blade 3-2 between two grooves.
During rotor rotation, the blade 3-2 on the trim ring body 3 rotates with the rotation of rotor, brings air quantity for the end ring 1 and the sliver 2 of rotor tip, and spreads wind by sliver 2 toward stator end, thereby play the effect of quickening heat radiation.
Because when the blade 3-2 on the trim ring body 3 rotates with rotor rotation, bring air quantity can for again the end ring 1 and the sliver 2 of rotor tip, and can be by sliver 2 toward stator end diffusion wind, inner to quicken toward outside heat transmission, thereby can improve the heat dispersion of motor, temperature rise when reducing motor work, the useful life of improving motor.
Claims (3)
1. an AC traction motor rotor core trim ring comprises rotor core trim ring body, it is characterized in that, evenly is provided with at least 20 grooves on the described trim ring body, forms blade between two grooves.
2. AC traction motor rotor core trim ring according to claim 1 is characterized in that the shape of cross section of described groove is circular-arc.
