Description

В насто щее врем  большое внимание придаетс  созданию виброудароустойчивых электродвигателей. Асинхронные электродвигатели с короткозамкнутым ротором, работающие в виброударном режиме, чаще всего выход т из стро  из-за нарушени  изол ции в лобовых част х обмоток статоров. Пропитка и заливка различными составами лобовых частей, а также установка металлического бандажа, выполненного в виде кольцевой колодки, в которой закрепл ютс  лобовые части обмотки, безусловно улучшают работу электродвигател .Much attention is currently being given to the creation of vibration-proof electric motors. Asynchronous squirrel-cage rotor motors operating in vibro-impact mode most often fail due to insulation failure in the frontal parts of the stator windings. The impregnation and pouring of various compositions of the frontal parts, as well as the installation of a metal band made in the form of an annular pad in which the frontal parts of the winding are fixed, certainly improve the operation of the electric motor.

Однако после установки статора в корпус электродвигател  (особенно при встроенном исполненпи двигател ) между корпусом и лобовой частью обмотки статора остаетс  значительный зазор, вследствие чего лобова  часть при вибрацн .х и ударах представл ет из себ  как бы консольную балку.However, after installing the stator into the motor case (especially with the built-in engine), there is a significant gap between the case and the frontal part of the stator winding, as a result of which the front part is vibrated like a cantilever beam when vibrating and striking.

Дл  устранени  этого недостатка и повышени  тем самым виброударостойкости лобовых частей предлагаетс  указанную кольцевую колодку выполнить в виде кольцевой коробки с концентричными стенками, котора  при надевании на лобовые части охватывает их с трех сторон.To eliminate this drawback and thereby increase the vibro-shock resistance of the frontal parts, the said ring block is proposed to be in the form of an annular box with concentric walls, which, when put on the frontal parts, covers them from three sides.

На фиг. 1 схематически показано предлагаемое устройство дл  креплени  лобовых частей обмотки статора асинхронного электродвигател ; на фиг. 2 изображен разрез колодки.FIG. 1 shows schematically the proposed device for fastening the frontal parts of the stator winding of an asynchronous electric motor; in fig. 2 shows a slit pads.

Как видно из фиг. 1, в зазоре между корпусом / электродвигател  и лобовой частью 2 обмотки статора установлена кольцева  колодка ., котора , в зависимости от конструкции, может быть разрезной и состо ть из секторов, устанавливаемых в местах наибольших деформаций . Как показано на фиг. 2, изображающей разрез кольцевой колодки , она выполнена в виде коробки с концентричными стенками а и б. При надевании этой кольцевой коробки на лобовые части концентричные стенки а, б и бокова  стенка в охватывают лобовые части с трех сторон. Подбор размеров стенок а, б. в кольцевой колодки, ее формыAs can be seen from FIG. 1, an annular pad is installed in the gap between the housing / motor and the frontal part 2 of the stator winding, which, depending on the design, can be split and consist of sectors installed in places of greatest deformations. As shown in FIG. 2, showing a section of an annular shoe, it is made in the form of a box with concentric walls a and b. When donning this ring box on the frontal parts, the concentric walls a, b and the side wall in cover the frontal parts on three sides. Selection of wall sizes a, b. in the ring pads, its shape
