Technical field
The utility model belongs to motor winding manufacturing technology field, particularly relates to a kind of winding overhang fixed structure with the effect of keeping out the wind.
Background technology
Along with the development of electric manufacturing, the high jumbo motor in low center is the inevitable demand in market.As everyone knows, in the situation that the motor shaft center is high certain, the stator punching internal-and external diameter is subject to certain restrictions, according to the principle of Electrical Motor, single-machine capacity increases gradually, it is elongated that motor will be tending towards, and winding overhang must lengthen, therefore, research and develop a kind of novel winding overhang fixed structure, and guarantee that motor volume is little, compact conformation, the reliability higher position seems particularly important.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and provides a kind of simple and reasonable for structure, can guarantee that motor volume is little, the winding overhang fixed structure of compact conformation, high the having of the reliability effect of keeping out the wind.
For solving the problems of the technologies described above, the technical solution of the utility model is:
a kind of winding overhang fixed structure with the effect of keeping out the wind, comprise the deep bead of being located at winding overhang middle part in electric machine casing, be complementary with winding overhang, and be fixed on the stator pressing ring outer circumference surface and the end hoop coaxial with the iron core external diameter by screw rod, be fixed with and the endless member of holding the hoop coaxial line between described deep bead and end hoop, the winding coil inner circle fixedly is embedded with the fan shroud coaxial with the iron core external diameter, between described end hoop and winding coil, the winding coil end outer surface is organized between coil to each utmost point of inner surface mutually, between the phase and phase coil, between the levels coil, fixedly be filled with respectively adaptive material and collets between winding coil inner circle and fan shroud.
Stator pressing ring is provided with screwed hole, and described screw rod is that screw thread is fixedly connected with stator pressing ring.
Described end hoop adopts the formed high-strength insulating material to make.
Described end hoop and the corresponding end face of winding overhang are the taper surface that is complementary with winding overhang.
Described fan shroud inner end does not exceed the end face at iron core external diameter place.
Described adaptive material and collets are fixed by washing the colligation of ripple rope.
The beneficial effect of technical solutions of the utility model is:
1, structurally, the winding overhang fixed structure that the utlity model has the effect of keeping out the wind comprises deep bead, end hoop, endless member, fan shroud and adaptive material and collets, simple in structure, reasonable in design, this winding overhang fixed form, the way that has replaced traditional coil lashing twice end hoop, replaced the way of welding deep bead or mounting block air duct on traditional support dividing plate, the utility model had both satisfied the reliable fixing of winding overhang, and the axial dimension of compact conformation, casing shortens dramatically, weight saving, reliability is strong.
2, structurally, the utility model stator pressing ring is provided with screwed hole, and described screw rod is that screw thread is fixedly connected with stator pressing ring, mounts and dismounts easy to maintenance; Described end hoop adopts the formed high-strength insulating material to make, and described end hoop and the corresponding end face of winding overhang are the taper surface that is complementary with winding overhang, and described fan shroud inner end does not exceed the end face at iron core external diameter place, and structural design is more reasonable; Described adaptive material and collets are fixed by washing the colligation of ripple rope, the method simple possible, and reliability is strong, is conducive to promotion and implementation.
3, in addition, the utility model adopts said structure, also play the effect of effectively keeping out the wind, make air intake not only from air intake between end winding and end cap, but also from air intake between the coil in the enclosure space of the above-mentioned formation outside, increased incoming air area, not only cooling favourable to end winding, and also very favourable to the cooling capacity of each parts of motor internal, therefore, be very suitable for promotion and implementation.
