Abstract
The utility model discloses a novel composite motor iron core end plate, which comprises an iron core, end plates and laminations. The end plates adopt circular bodies with heaves; tooth parts communicated with the laminations are formed at the circumferences of the semicircular end plates; the semicircular end plates are used for tightly pressing two ends of the laminations which are overlapped for a certain height, and are fixedly connected by cramps or stator ribs; and the laminations are sleeved on the iron core. The composite motor iron core end plate has the advantages of good mechanical property, beautiful appearance, long service life, low cost and economic and practical use, and can effectively and better prevent the problems that the tooth parts bounce off, and the like from occurring due to the tight pressing of the yoke parts and the tooth parts of the iron core.
Description
Technical field:
The utility model relates generally to electric machine iron core end plate field, relates in particular to a kind of New-type electric machine combined type core end plate.
Technical background:
Electric machine iron core is the motor cardiac component, is made up of punching, end plate, trim ring, cramp etc., and punching is after being press fit into design height, and two ends compress iron core by end plate and trim ring, and squeeze into cramp or welding.Now general traditional low voltage motor end plate is to be come out by the punching press of punching flute profile by the thick sheet metal of 1mm-2mm, is pressed in to press-fit in the good punching, and trim ring is pressed on the end plate again, uses the cramp fastening again; The high-voltage motor two ends are pressed on the stator punching with the stator ventilation channel plate, are pressed on the stator ventilation channel plate at two ends with stator pressing ring again, fix the two ends trim ring by welding stator muscle.Because stator pressing ring and end plate are two independently integral body, and its structure all is a straight integral body, the stator pressing ring internal diameter is bigger than stator punching trench bottom diameter, can only compress the yoke portion of stator punching like this, owing to only be subjected to the effect of monolateral power, what cause that the tooth portion of stator core can only a threshold quantity compresses the phenomenon that causes tooth portion to flick.Because the tooth portion of iron core flicks, and has influenced the actual size of iron core, the motor properties of the tooth portion that flicks simultaneously is subjected to certain influence.
The utility model content:
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of motor combined type core end plate new design is provided, make core flange and end plate become a combined type overall structure, can compress the effect of iron core yoke portion and tooth portion effectively, the tooth portion that reduces iron core to greatest extent flicks.
The utility model is achieved through the following technical solutions:
A kind of New-type electric machine combined type core end plate, include iron core, end plate, punching, it is characterized in that: described end plate is the annular solid that has projection, described end plate periphery has the teeth groove that is used to place the punching end, two ends, described punching assembling back compress with end plate respectively, and are fixedly connected by cramp or stator muscle between the described end plate.
Two kinds of described punching difference stator punching and rotor punchings.
The utility model makes original trim ring and end plate become a combined type overall structure, its structure is the integrally stretching particular design, size is decided according to designing requirement, is pressed on the iron core two ends that press-fit by designing requirement after overall structure machines, and welds cramp or stator muscle again.Because of it is a particular design, after press-fiting welding, the combined type core end plate has higher mechanical strength, can effectively, better compress iron core yoke portion again, also can compress iron core teeth portion to greatest extent simultaneously, the more effective iron core teeth portion that prevents flicks, solve all the time and flick a series of problems that cause owing to iron core press-fits tooth portion, because former trim ring is replaced by the stretching of combined type stator end plate yoke portion, economical with materials has reduced cost more than 50% simultaneously.
The utility model has the advantages that:
The utility model good mechanical property, good looking appearance can effectively, better compress the yoke portion and the tooth portion of iron core, prevents the appearance of problems such as tooth portion flicks, and long service life, and cost is low, and is economical and practical.

Embodiment:
A kind of New-type electric machine combined type core end plate, include iron core 1, end plate 2, stator or rotor punching 3, described end plate 2 is for having the annular solid of projection 4, described end plate 2 peripheries have the teeth groove that is used to place punching 3 ends, 3 assemblings of described stator or rotor punching are closed two ends projection 4 parts and are extend into respectively in the teeth groove 6 on the end plate 2, and compress with end plate 2, fixedly connected by cramp 5 or stator muscle between the described end plate 2, described punching 3 is set on the iron core 1.
