Abstract
The utility model discloses a motor rotor punching sheet comprising a punching sheet body, punching sheet grooves and a clamping ring which is connected with a rotating shaft on the internal circle of the punching sheet body. 30 punching sheet grooves are evenly distributed on the external circumference of the punching sheet body. With increasing of number of groove mouths, power of a motor is effectively increased to 0.12KW so that the service life of the motor is prolonged.
Description
Technical field
The utility model relates to machine field, especially relates to a kind of motor rotor punching sheet.
Background technology
Motor is widely used in the fields such as traffic, building, industry at present.Motor is mainly stator and rotor, to consist of, this rotor is to be formed by stacking by several rotor punchings, rotor punching is the critical component of motor, its excircle dimension, flute profile size, how many efficiency on motor has direct impact, and most rotor punching is hollow-core construction in the market, can not adapt to the motor of different-diameter, because die sinking expense is high, be unfavorable for saving production cost.
For this phenomenon, Chinese patent CN202651922 discloses a kind of punching, and this punching can adapt to by adjusting the center-hole diameter of chuck the motor of different-diameter.But when the punching of this structure is used, punching cannot make the power of motor reach 0.12KW, and long-term use can make winding temperature rise too high, causes shorten dynamo-electric useful life.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of compact conformation, is applicable to the motor of different-diameter, and power can reach 0.12KW, extends the motor motor rotor punching slice in useful life.
To achieve these goals, the utility model is by the following technical solutions: a kind of motor rotor punching sheet, the snap ring that comprises connection rotating shaft on punching body, punching groove and this this inner ring of punching, on described punching body excircle, be evenly equipped with 30 punching grooves, can make different-diameter power of motor can reach 0.12KW, extend the life-span that motor uses.
As preferably, described punching groove is to be connected to form by first groove of circular arc and second groove, and this first groove diameter is 2.9mm, and this second groove radius is 2.8mm, and slot opening is 0.8mm, and notch height is 0.42mm.
As preferably, described snap ring is the wheel hub snap ring of the diameter of capable of regulating snap ring centre bore.By adjusting the diameter of snap ring centre bore, can realize the demand of different-diameter rotating shaft electric motor.
As preferably, described wheel hub snap ring comprises 4-6 root back shaft and the louvre being surrounded by this back shaft.
As preferably, described louvre is shaped as fan-shaped.
In sum, the utlity model has following advantage: adopt the power of the motor of this punching can reach 0.12KW, in the useful life that extends motor, strengthened radiating effect, and can realize by adjusting the diameter of snap ring centre bore the demand of different-diameter rotating shaft electric motor.
Accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of single punching groove in Fig. 1.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1-2, a kind of motor rotor punching sheet, the snap ring 3 that comprises connection rotating shaft on this 1 inner ring of punching body 1, punching groove 4 and this punching, described punching body 1 excircle is evenly equipped with 30 punching grooves 4, by increasing punching groove number, makes the power of motor higher, can reach 0.12KW, good heat dissipation effect, winding temperature rise speed slows down, and extends the useful life of motor.
Concrete, described punching groove 4 is that first groove 41 and second groove 42 by circular arc connects to form, and these first groove 41 diameters are 2.9mm, these second groove 42 diameters are 2.8mm, the part that this punching groove approaches punching excircle is notch 9, and described notch 9 is wide is 0.8mm, and the height of this notch 9 is 0.42mm.The punching flute profile of above size and circular arc design, has expanded the area of punching groove flute profile, can embed more copper cash.
Described snap ring 3 is the wheel hub snap ring of the diameter of capable of regulating snap ring centre bore, realizes the demand of different-diameter rotating shaft electric motor by adjusting the diameter of snap ring 3 centre bores, strengthens the utilance of punching, has saved material.
Further, the near inner ring of described wheel hub snap ring decentre Kongzui is snap ring inner ring, this snap ring comprises 6 back shafts 7, these back shaft 7 one end connect punching inner ring, the other end connects from snap ring inner ring, forms thus louvre 8, and this louvre is conducive to improve the radiating effect of motor, and then improve the efficiency of motor, avoid in machine operation process temperature too high and damage.
The shape of described louvre 8 has multiple, and in this example, louvre 8 is shaped as fan-shaped louvre.The louvre of this shape, saves material, and heat dispersion is best.
Obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
