Abstract
This invention discloses a ventilated channel board of a motor rotor; the lengths of ventilated channel sheets are basically equal to the annular width of a ventilated channel bottom board; the ventilated channel sheets are installed and welded with the ventilated channel bottom board of a rotor in an orthogonal manner; according to the ventilated channel board disclosed by this invention, after the ventilated channel sheets are lengthened, a welding area is enlarged, thus, connection between the ventilated channel sheets and the ventilated channel bottom board is more stable so as to effectively prevent a problem that an inner hole of an armature ventilated channel board is deformed so as to cause potential safety hazard such as a popped armature teeth part, a flied-off ventilated channel sheet and the like; the long-time running of a motor is ensured reliably; the ventilated channel sheets which have equal heights are evenly distributed on a rotor ventilated channel board in a welding manner; and armature pressing rings are pressed on the ventilated channel sheets with the same heights so as to effectively avoid the armature teeth part being popped. According to the ventilated channel board disclosed by this invention, the running safety of the ventilated channel board is enhanced, raw material is saved, armature teeth are prevented from being popped, the strength of the armature ventilated channel board is enhanced, and the safe/reliable long-time running of the motor is ensured.
Description
Technical field
The present invention relates to the dc motor technology field, especially the ventilation channel plate of rotor.
Background technology
The armature of direct current machine is a rotating parts, in order to realize energy converting between mechanical, mainly is made up of parts such as axle, armature core, armature end flange, armature winding, commutator and fans.Armature core is the part of motor magnetic circuit, is again the strutting piece of armature winding; The armature core shelves are fastened fixing by the armature trim ring at two ends, the armature trim ring is pressed on the ventilation channel plate, and the evenness of ventilation channel plate has determined the degree of reliability that fastens of armature trim ring and ventilation channel plate.Vent segment is very short in the ventilation channel plate of existing structure, near annulus of ventilation channel plate internal diameter welding, the annulus height in theory with height such as vent segment grade, still, two kinds separately the material height of usefulness can't guarantee absolute unanimity.If the annulus height a little more than the vent segment height, has just compressed the annulus position when then the armature trim ring is pressed on the ventilation channel plate, vent segment is failed compacted; In motor operation course, the vent segment in the armature that is rotating just has the possibility that flies out and, and the tooth portion of armature stamping can flick, and can cause noise in the running, and the vibration of tooth portion then can cause the damage of slot liner, thereby can shorten the useful life of motor.If the annulus height is lower than the vent segment height, then trim ring might not press tightly circle in the armature core, and circle distortion in the iron core diminishes long-term use the, the displacement of can skidding, generation operation troubles with the actual magnitude of interference of axle.
Summary of the invention
The applicant is to there being shortcomings such as highly inconsistent in the above-mentioned existing ventilation channel plate; A kind of ventilation channel plate of rotor rational in infrastructure is provided; Thereby strengthened the safety in operation of ventilation channel plate, saved raw material, also can avoid armature tooth to flick; Improved the intensity of armature ventilation channel plate, guaranteed that the motor long-term safety moves reliably.
The technical scheme that the present invention adopted is following:
A kind of ventilation channel plate of rotor, the length of vent segment equal the annular width of ventilation slot base plate basically, carry out assembly welding with rotor ventilation trough floor quadrature.
Beneficial effect of the present invention is following:
Behind the vent segment lengthening of the present invention; Increase bonding area, made connection between the two more fastening, effectively prevented armature ventilation channel plate Internal Hole Deformation; Potential safety hazard such as cause armature tooth portion to flick, vent segment flies out is for the long-term safety operation of motor provides more reliable guarantee.The vent segment of equal height is welded on the rotor ventilation frid evenly distributedly, and the armature trim ring is pressed on the vent segment of equal height, can effectively avoid armature tooth portion to flick.
Contrast through actual tests: the rotor ventilation frid of identical flute profile slotted vane number, adopt whole ventilation channel plate of the present invention more much higher than the integral smoothness of existing ventilation channel plate structure; Under the prerequisite that does not increase associated materials and cost; Through appropriate design to structure, reduced the possibility that the motor ventilation slotted vane flies out, reduced because of armature tooth portion flicking the possibility that causes noise; The process that the damage of the armature slot liner that slowed down is aging has prolonged useful life of motor.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is assemblied in the sketch map on the armature core for structure of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described.
As shown in Figure 1; The vent segment 2 that the present invention includes is than existing short vent segment; Extend downwards and extend near rotor ventilation trough floor 1 inner radius, promptly the length of vent segment 2 equals the annular width of ventilation slot base plate 1 basically, and carries out assembly welding with rotor ventilation trough floor 1 quadrature.The vent segment 2 owing to extended has increased the welding contact-making surface, has therefore increased the fastness after the welding.As shown in Figure 2, after armature trim ring 3 compresses ventilation slot base plate 1, be pressed in simultaneously on the vent segment 2 of equal height, closely contact with the rotor ventilation frid, armature tooth is also tightly pushed down.The present invention has cancelled the annulus near the ventilation channel plate internal diameter in the existing structure, and only with a kind of material vent segment, thereby the rotor ventilation frid evenness behind the whole circle assembly welding vent segment is very high.The present invention is simple in structure, and effect is obvious, has improved armature ventilation channel plate evenness, reduces the risk that revolving part flies off, and has improved the operational reliability of motor.
