Abstract
The utility model discloses an AC motor rotor. The rotor comprises a rotor body (1), a shaft hole (2) is arranged in the center of the rotor body (1), end rings (3) are arranged on two lateral sides of the rotor body (1), and annular plummer blocks are arranged at two ends of the shaft hole (2). According to the AC motor rotor, not only the deformation degree of the shaft hole during aluminum casting can be reduced, but also the exerted riveting force during riveting of a spindle can be reduced and the problem that the spindle tilts and deforms caused by overlarge riveting force during the assembling is solved. Additionally, materials are saved, and the production cost is reduced by aid of the AC motor rotor.
Description
Technical field
The utility model relates to a kind of AC motor rotor, belongs to the motor manufacture field.
Background technology
Rotor is the core component of alternating current machine, and the structure quality of rotor will directly influence the performance and the life-span of alternating current machine.The primary structure of AC motor rotor is exactly to laminate the rotor subject that obtains by rotor punching, is provided with axis hole in the middle of the rotor subject, is equipped with armature spindle in the axis hole; Adopt the self-clinching close-fitting to fix between armature spindle and the rotor subject, yet the structure of existing rotor subject makes rotor subject and rotating shaft in assembling process, need to adopt bigger rivet force; In the riveting process and make axes of rotation skew distortion easily; Cause rotor to be beated greatly, cause motor noise, vibration greatly, influence the serviceability of motor; Simultaneously, the structure of existing rotor subject makes that also rotor axis hole when cast aluminium is yielding, therefore how to improve the structure of rotor subject, solves the above-mentioned problem that influences motor performance, becomes the task that the technical staff needs to be resolved hurrily.
The utility model content
The purpose of the utility model is, a kind of AC motor rotor is provided.The degree of axis hole distortion when the utility model not only can reduce cast aluminium, and the rivet force that applies can reduce to rivet rotating shaft the time have solved both cause the axes of rotation skew distortion when assembling because of rivet force is excessive problem; In addition, the utility model also increases waste material on original basis, reduced production cost.
The technical scheme of the utility model: a kind of AC motor rotor, comprise rotor subject, the central authorities of rotor subject are provided with axis hole, and the two sides of rotor subject are provided with end ring, it is characterized in that: the two ends of described axis hole respectively are provided with an annular pillow block.
In the above-mentioned AC motor rotor, it is characterized in that: the axial height H of described annular pillow block is 1～2mm.
In the aforesaid AC motor rotor, the radial diameter φ of described annular pillow block=18～22mm.
Compared with prior art; The utility model cuts some at the two ends in the commentaries on classics hole of existing rotor subject; Respectively form an annular pillow block at the axis hole two ends, so the axial dimension of the axis hole of the utility model shortens greatly, also promptly reduced the contact area of axis hole and rotating shaft; The rivet force that applied when having reduced the riveted joint rotating shaft has solved the problem that both cause the axes of rotation skew distortion when assembling because of rivet force is excessive; Because the axial dimension of axis hole shortens, the degree of axis hole distortion when the utility model can also reduce cast aluminium reduces rotor and beats, thereby falls a motor noise, vibration, improves the serviceability of complete machine simultaneously.In addition, when the annular pillow block of processing, can produce certain waste material, this waste material can be sold (waste material sale), thereby has reduced production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Being labeled as in the accompanying drawing: 1-rotor subject, 2-axis hole, 3-end ring, 4-annular pillow block.
Embodiment
Below in conjunction with embodiment the utility model is done further to specify, but not as the restriction to the utility model.
The embodiment of the utility model: a kind of AC motor rotor, shown in accompanying drawing 1, comprise rotor subject 1, the central authorities of rotor subject 1 are provided with axis hole 2, and the two sides of rotor subject 1 are provided with end ring 3, and the two ends of said axis hole 2 respectively are provided with an annular pillow block 4; The axial height H of described annular pillow block 4 is 1～2mm; The radial diameter φ of described annular pillow block 4=18～22mm, above-mentioned axial height and radial diameter are that the applicant obtains through repetition test, screening, summary, adopt this size, can guarantee rotor performance, can obtain the goal of the invention of the utility model again.The utility model cuts some at the two ends in the commentaries on classics hole of existing rotor subject; Respectively form an annular pillow block at the axis hole two ends; Therefore the axial dimension of the axis hole of the utility model shortens greatly; Also promptly reduced the contact area of axis hole and rotating shaft, the rivet force that applied when having reduced the riveted joint rotating shaft has solved both cause the axes of rotation skew distortion when assembling because of rivet force is excessive problem; Simultaneously because the axial dimension of axis hole shortens the degree of axis hole distortion when the utility model can also reduce cast aluminium, the performance of raising rotor.In addition, when the annular pillow block of processing, can produce certain waste material, this waste material can be reprocessed, thereby has reduced production cost.
Claims (3)
1. an AC motor rotor comprises rotor subject (1), and the central authorities of rotor subject (1) are provided with axis hole (2), and the two sides of rotor subject (1) are provided with end ring (3), it is characterized in that: the two ends of said axis hole (2) respectively are provided with an annular pillow block (4).
2. AC motor rotor according to claim 1 is characterized in that: the axial height H of described annular pillow block (4) is 1～2mm.
