A substantially tubular structure (102) comprises a central axis (104) through a longitudinal geometric center, and a first fan (108) rotates around the central axis, and comprises a first fan hub (110) and first fan blades (112). The fan hub (108) is rotationally coupled to the substantially tubular structure (102), and the first fan blades (112) are coupled to the first fan hub (110) and increase in chord length with increasing distance from the first fan hub (108). A second fan (118) is rotationally coupled to the substantially tubular structure (102) and rotates around the central axis and contra-rotates relative to the first fan (108). Second fan blades (118) are coupled to the second fan hub (120), and a nacelle (124) circumscribing the first fan (108) and the second fan (118) is coupled to and rotates with the first fan (108).

    摘要: The invention relates to a system for balancing a movable turbine part (110) of a turbine or of a compressor. The system comprises a balancing weight element (100) with a first hole (101) and a second hole (102) and a fixing element (201). The first hole (101) and the second hole (102) are formed in such a manner that the fixing element (201) is detachably insertable in either the first hole (101) or the second hole (102). The first hole (101) is formed in such a manner that the inserted fixing element (201) in the first hole (101) detachably couples the balancing weight element (100) to the movable turbine part (110) in a spatially fixed position. The second hole (102) is formed in such a manner that the fixing element (201) is receivable in the second hole (102), when the balancing weight element (100) is non-detachably fixed to the movable turbine part (110) in the spatially fixed position.

    摘要: Provided is a motor device capable of suppressing undesired vibrations occurring at the time of starting a motor, by canceling a torque in a motor device system so as to reduce a reaction torque acting on a motor base. The motor device is equipped with a dual axis motor 1 having first and second rotating shafts 10a and 10b projecting at either end, a rotational direction converter 2 having an input shaft 20a to which the torque of the dual axis motor 1 is inputted and an output shaft 20b that outputs the torque by rotating in a direction opposite to that of the input shaft 20a, and a flywheel 3 provided at an end portion of the first rotating shaft 10a, for balancing out the reaction torque acting on the input shaft 20a and the output shaft 20b of the rotational direction converter 2 when the dual axis motor 1 rotates.
