Abstract
The utility model relates to an electric machine rotor core, it includes pivot, rotor clamping ring, rotor punching, rotor ventilation frid, arc key, length is different dashes the piece equipment in the pivot to the excircle for the rotor punching of tooth portion form builds up, towards separating with rotor ventilation frid between the piece group, both ends dash the rotor clamping ring that piece group tip do not was equipped with the symmetric placement, the inboard of rotor clamping ring is equipped with concave tang, and the inboard excircle of rotor clamping ring contacts with the tooth portion of rotor punching, and the rotor clamping ring of one end keeps off the shoulder location for the pivot, and the rotor clamping ring of the other end passes through sectional type arc key to be fixed together with the pivot. The utility model discloses owing to be equipped with concave tang on the rotor clamping ring, the iron core compresses tightly the position and is close to tooth portion, has reduced the rotor core tooth and has expanded. The utility model discloses still relate to a motor, it contains rotor core, rotor core is above -mentioned rotor core.
Description
Technical field
The utility model relates to a kind of motor rotor core and motor.
Background technology
At present, the rotor pressing ring of motor rotor core and the faying face of rotor punching adopt whole plane to fit usually, rotor pressing ring and rotating shaft be fixed on rotor pressing ring inner circle, punching expansive force causes rotor punching teeth portion swell increment comparatively large, easily causes vibrating during motor rotation.Fixing employing segmented arc bond structure between rotor pressing ring and rotating shaft, arc key is directly welded on rotor pressing ring, and arc key, once sealing-off, can cause motor operation troubles.Rotor iron core lamination group adopts isometric segmentation, and because iron core stage casing radiating condition is poorer than iron core two ends, iron core stage casing temperature is higher than iron core two ends, and iron core temperature distributing disproportionation is even.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect, and provide one can reduce rotor core tooth bulk, arc key fixes safety and reliability, the rotor core of uniformity of temperature profile and comprise the motor of this rotor core.
The technical solution of the utility model is: a kind of motor rotor core, it comprises rotating shaft, rotor pressing ring, rotor punching, rotor ventilation frid, arc key, cylindrical is that the rotor punching of teeth portion shape builds up the different punching of length and is assembled in rotating shaft, separate with rotor ventilation frid between punching group, the punching group end at two ends is respectively equipped with the symmetrical rotor pressing ring placed, the inner side of described rotor pressing ring is provided with recessed seam, the inner side cylindrical of rotor pressing ring contacts with the teeth portion of rotor punching, the rotor pressing ring of one end is rotating shaft shoulder block location, the rotor pressing ring of the other end is fixed together by segmented arc key and rotating shaft.
In order to increase the fixing reliability of arc key, also comprise relieving ring, described relieving ring is circular, and the internal diameter of described relieving ring and the external diameter of arc key match and to be stuck by segmented arc key, and external diameter and the rotor pressing ring of described relieving ring are fixed together.
For the ease of installing, outside relieving ring, be provided with the disconnection annulus of opening.
In order to make iron core uniformity of temperature profile, described punching group length is middle from rotor core two ends to rotor core to be shortened gradually.
The utility model additionally provides a kind of motor, and it comprises rotor core, and described rotor core is rotor core described above.
The beneficial effects of the utility model are, because rotor pressing ring is provided with recessed seam, iron core compresses position near teeth portion, reduces rotor core tooth swollen.Owing to being provided with relieving ring outside arc key, utilize relieving ring that the arc key card of segmented is become an entirety, add the reliable degree of arc key, in addition, shorten gradually because rotor iron core lamination group length is middle from iron core two ends to iron core, iron core stage casing is more than iron core two ends air duct, and draught area is large, iron core cooling is more abundant, iron core homogeneous temperature.
