Description

Предлагаемое изобретение предназначаетс  дл  укреплени  лобовых соединений обмоток роторов электрических машин при посредстве металлических колпаков..The present invention is intended to strengthen the frontal connections of the rotor windings of electrical machines by means of metal caps.

На чертеже изображен продольный разрез ротора с массивным колпаком, прикрепленным своим внутренним концом к сердечнику ротора, при чем внутренний конец колпака ослаблен из конструктивных соображений.The drawing shows a longitudinal section of the rotor with a massive cap attached by its inner end to the core of the rotor, while the inner end of the cap is loosened due to structural considerations.

В месте соединени  сердечника ротора 1 и массивного колпака 2, надвинутого на лобовые соединени  3 обмоток, материал колпака не только подвергнут наибольшему напр жению, но в то же врем  требуетс , чтобы в этом же месте материал колпака обладал плохой магнитной проницаемостью. Внутренний конец колпака ослаблен изAt the junction of the core of the rotor 1 and the massive cap 2 pulled over the frontal connections 3 of the windings, the cap material is not only subjected to the greatest stress, but at the same time it is required that in the same spot the cap material has poor magnetic permeability. The inner end of the cap is loose from

конструктивных соображений. Колпак 2 снабжен в местах примыкани  к активному слою железа ротора 1 двум  кольцевыми выточками 4 и 6. В ближайшую к ротору 1 выточку 4 помеш.ен бандаж 5 с плохой магнитной проницаемостью, а во вторую выточку б-бандаж 7 из материала с высоким пределом т гучести. Такой способ укреплени  имеет целью получить одновременно с необходимым вли нием на магнитный поток также и требуемую прочность колпака против напр жений от центробежной силы.design considerations. Cap 2 is provided with two annular recesses 4 and 6 in places adjoining the active layer of iron of the rotor 1. In the nearest recess 1 to the rotor 4 there is a band 5 with poor magnetic permeability, and a b band 7 made of a material with a high limit t guciness This method of strengthening is aimed at simultaneously obtaining the required effect on the magnetic flux and the required strength of the cap against stresses from centrifugal force.

Предмет патента.The subject of the patent.
