Description
Предлагаема конструкци бандажа дл креплени лобовых частей обмотки ротора турбогенератора отличаетс от известных тем, что бандаж состоит -из двух цилиндрических колец: внутреннего, изготовленного из прочной стали, и -внешнего, изготовленного из прочного и легкого сплава, например титанового.The proposed band design for fastening the frontal parts of the rotor winding of a turbogenerator differs from the known ones in that the bandage consists of two cylindrical rings: an inner one made of strong steel, and an outer one made of a strong and lightweight alloy such as titanium.
Такое выполнение бандажа позвол ет уменьшить в нем механические напр жени и предотвратить деформацию.Such an embodiment of the bandage makes it possible to reduce mechanical stresses in it and to prevent deformation.
На чертеже изображена схема предлагаемого бандажа.The drawing shows the scheme of the proposed band.
Бандажное кольцо изготовл етс составным из двух цилиндрических колец 1 ч 2. Внешнее кольцо / изготовл етс из легкого и прочного титанового сплава, а внутреннее кольцо 2 - из обычной бандажн&й стали. До посадки бандажного кольца на вал ротора 3 внешнее кольцо / насаживаетс в нагретом состо нии с соответствуюш,им нат гом на внутреннее кольцо 2. В результате этого во внутреннем кольце создаютс сжимающие, а во внешнем кольце раст гивающие усили .The band ring is made of composite from two cylindrical rings for 1 hour. The outer ring / is made of light and durable titanium alloy, and the inner ring 2 is made of ordinary bandage steel. Before the retaining ring is seated on the rotor shaft 3, the outer ring / is seated in a heated condition with a corresponding tension on the inner ring 2. As a result, compressive forces are created in the inner ring, and tensile forces are formed in the outer ring.
