Abstract
1. Валопровод турбоагрегата, содержащий скрепленные между собой соединительными муфтами и установленные на подшипниковых опорах роторы многоцилиндровой паровой турбины и электрогенератора, отличающийся тем, что каждая из указанных соединительных муфт объединена с общей для двух стыкуемых ею роторов подшипниковой опорой, а внешние цилиндрические поверхности ответных полумуфт каждой муфты в совокупности служат в качестве опорного элемента вала в опорном или опорно-упорном подшипнике скольжения соответствующей подшипниковой опоры.2. Валопровод турбоагрегата по п. 1, отличающийся тем, что внешние торцевые поверхности ответных полумуфт одной из указанных соединительных муфт служат в качестве упорных элементов вала в опорно-упорном подшипнике скольжения одной из указанных общих для двух стыкуемых роторов подшипниковой опоры.3. Опорный или опорно-упорный подшипник скольжения подшипниковой опоры валопровода турбоагрегата, у которого в качестве опорных или опорных и упорных элементов вала служат внешние поверхности стягиваемых шпильками ответных полумуфт соединительной муфты двух смежных роторов указанного валопровода, отличающийся тем, что разность диаметров указанных полумуфт одной соединительной муфты составляет не более 10 мкм, стяжные шпильки выполнены легкосъемными с промежуточными упругими распорными втулками, а отверстия под стяжные шпильки в стыкуемых полумуфтах закрыты заподлицо с торцами полумуфт защитными колпачками.1. Shaft of a turbine unit, comprising rotors of a multi-cylinder steam turbine and an electric generator mounted together by connecting couplings and mounted on bearing bearings, characterized in that each of these connecting couplings is combined with a bearing support common to two rotors joined by it, and the outer cylindrical surfaces of the response coupling halves of each the couplings together serve as a support element of the shaft in the support or support-thrust sliding bearing of the corresponding bearing support. 2. The shaft assembly of a turbine unit according to claim 1, characterized in that the outer end surfaces of the mating half couplings of one of said coupling couplings serve as thrust shaft elements in a thrust journal bearing of one of the bearing bearings which are common to two mating rotors. 3. A thrust bearing or thrust bearing of a bearing support of a turbine shaft shaft, in which the outer surfaces of the coupling half-couplings of two adjacent rotors of the said shaft shaft, which are pulled together by the coupling pins, are used as supporting or supporting and thrust shaft bearings, characterized in that the difference in the diameters of said coupling halves of one coupling is no more than 10 microns, the tie rods are made easily removable with intermediate elastic spacer sleeves, and the holes for the tie rods in the joint The coupling halves are closed flush with the ends of the coupling halves with protective caps.
