Description
Technical field
The utility model relates to large-size machine stator winding end technique for fixing, is related specifically to a kind of large-size machine stator winding end fixed structure.
Background technology
Large-size machine because of its capacity comparatively large, starting current is comparatively large, needs to be fixed process to the end of stator winding, makes it when electric motor starting, can not produce rock because of larger electromagnetic vibration power, thus causes loosening, wearing and tearing or fracture.Prior art large-size machine stator winding end fixed structure adopts end hoop to be fixed together by stator winding end, is namely sleeved on two end hoops at winding overhang, is then banded together with insulating tape.Although this method adds the fastening of winding overhang, when large electromagnetic vibration power, still can produce from the joint portion of winding overhang and stator core and rock, thus cause wearing and tearing or the fracture of joint portion.Obviously, the joint portion that prior art large-size machine stator winding end fixed structure also exists winding overhang and stator core easily produces rocks, thus causes the problem such as wearing and tearing or fracture of joint portion.
Summary of the invention
Joint portion for the winding overhang and stator core that solve the existence of prior art large-size machine stator winding end fixed structure easily produces rocks, thus cause the problem such as wearing and tearing or fracture of joint portion, the utility model proposes a kind of large-size machine stator winding end fixed structure.The utility model large-size machine stator winding end fixed structure, it is characterized in that, bracing frame, support arm and end hoop is adopted to be fixed together by stator winding end, at stator core end face, bracing frame is set, bracing frame arranges support arm, the inner side of support arm is provided with colligation through hole, adopts insulated binding band to be linked together with support arm by end hoop through colligation through hole; Wherein, support frame as described above is L shape structure, and one end of L shape is bolted on stator core end face, and the other end is connected with support arm by bolt.
Further, the through hole that the utility model large-size machine stator winding end fixed structure support arm is connected with bracing frame is strip.
Further, the colligation through hole on the utility model large-size machine stator winding end fixed structure support arm is more than two or two.
The Advantageous Effects of the utility model large-size machine stator winding end fixed structure is can be effectively fixing by stator winding end, the joint portion of stator winding end and stator core also can not be produced when large electromagnetic vibration power rock, avoid the generation of the problems such as joint portion wearing and tearing or fracture.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of prior art large-size machine stator winding end fixed structure;
Accompanying drawing 2 is the schematic diagram of the utility model large-size machine stator winding end fixed structure.
Below in conjunction with the drawings and specific embodiments, the utility model large-size machine stator winding end fixed structure is further described.
Detailed description of the invention
Accompanying drawing 1 is the schematic diagram of prior art large-size machine stator winding end fixed structure, and in figure, 1 is stator core, and 2 is stator winding end, and 3 is winding leading-out wire, and 4 is end hoop.As seen from the figure, prior art large-size machine stator winding end fixed structure adopts end hoop 4 to be fixed together by stator winding end 2, is namely sleeved on two end hoops at winding overhang, is then banded together with insulating tape.Although this method adds the fastening of winding overhang, when large electromagnetic vibration power, still can produce from the joint portion of winding overhang and stator core and rock, thus cause wearing and tearing or the fracture of joint portion.Obviously, the joint portion that prior art large-size machine stator winding end fixed structure also exists winding overhang and stator core easily produces rocks, thus causes the problem such as wearing and tearing or fracture of joint portion.
Accompanying drawing 2 is the schematic diagram of the utility model large-size machine stator winding end fixed structure, and in figure, 1 is stator core, and 2 is stator winding end, and 3 is winding leading-out wire, and 4 is end hoop, and 5 is bracing frame, and 6 is support arm.As seen from the figure, the utility model large-size machine stator winding end fixed structure, it is characterized in that, bracing frame 5, support arm 6 and end hoop 4 is adopted to be fixed together by stator winding end 2, at stator core 1 end face, bracing frame 5 is set, bracing frame 5 arranges support arm 6, the inner side of support arm 6 is provided with colligation through hole, adopt insulated binding band end hoop 4 and support arm 6 to be linked together through colligation through hole; Wherein, support frame as described above 5 is L shape structure, and one end of L shape is bolted on stator core 1 end face, and the other end is connected with support arm 6 by bolt.Owing to adopting support arm, the winding overhang be fixed together is fixed, and support arm and bracing frame are for being rigidly connected, bracing frame and stator core are for being rigidly connected, therefore, there is larger electromagnetic vibration power that the joint portion of stator winding end and stator core also can not be made to produce in time to rock, avoid the generation of the problems such as joint portion wearing and tearing or fracture.For regulating the distance of support arm and winding overhang, the through hole that the utility model large-size machine stator winding end fixed structure support arm is connected with bracing frame is strip.Regulated the relative position of support arm and bracing frame by elongate holes, the distance of support arm and winding overhang can be regulated easily, ensure support and the fixed effect of support arm.In order to adapt to the winding overhang of different length, the colligation through hole on the utility model large-size machine stator winding end fixed structure support arm is more than two or two.When adopting insulated binding band to be linked together with support arm by end hoop through colligation through hole, the colligation through hole of diverse location can be selected according to the length of winding overhang, convenient and effectively ensure fixing of winding overhang.
Obviously, the Advantageous Effects of the utility model large-size machine stator winding end fixed structure is can be effectively fixing by stator winding end, the joint portion of stator winding end and stator core also can not be produced when large electromagnetic vibration power rock, avoid the generation of the problems such as joint portion wearing and tearing or fracture.
