Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
It please refers to Fig.1 shown in -5, a kind of cagelike structure of rotor, including quoit 1 and rotor core 8, quoit 1
Side end ring 3 is installed, rotor core 8 is installed in the side of end ring 3, several silicon steel sheets 2 are arranged in the outer wall of rotor core 8, if
Punching slot 9 is respectively provided between dry silicon steel sheet 2, the inside of punching slot 9 is respectively mounted conducting bar 4, and the bottom setting of conducting bar 4 is carved key 5, held
Several narrow slots 6 are arranged in the outer wall of ring 3, several narrow slots 6 are all provided with sipes 7 between any two.
As a kind of technical optimization scheme of the utility model, two end ring 3 are symmetrical set by rotor core 8, and
Quoit 1 is socketed in side of the end ring 3 far from rotor core 8, to make end ring 3 may be mounted at the both ends of rotor core 8,
And quoit 1 can be effectively protected the moulding constant of end ring 3.
As a kind of technical optimization scheme of the utility model, the trapezoidal structure in cross section of conducting bar 4, conducting bar 4 is close to be turned
Width inside sub- iron core 8 is more than the width far from separate rotor core 8, and the match specifications of conducting bar 4 and punching slot 9, from
And when so that conducting bar 4 is stuck in punching 9 inside of slot, since bottom edge is larger, thus will not because of centrifugal force effect and by conducting bar 4
Throw away rotor core 8.
As a kind of technical optimization scheme of the utility model, the length of conducting bar 4 is longer than silicon steel sheet 2, and the both ends of conducting bar 4
The outer wall of end ring 3 is welded on by narrow slot 6, when between making conducting bar 4 be stuck in silicon steel sheet 2, both ends can stretch out rotor iron
Core 8, to facilitate 8 both ends of rotor core end ring 3 welding.
