Abstract

PURPOSE:To enhance the stability of a vertical shaft type water-turbine generator by securing a bracket arm which holds an upper guide bearing to a peripheral wall with a device having small radial rigidity and large tangential rigidity, thereby absorbing the thermal expansion of the arm and suppressing the unbalance of a rotor. CONSTITUTION:The upper part of a rotational shaft 1 of an electromagnetic device having a rotor 8 and a stator 9 is journaled by a guide bearing 3, which is held by a bracket arm 5, and the end of the arm 5 is secured to the floor 13 of the peripheral concrete wall with a fastener 27. In this case, the fastener 27 is made of a supporting plate 29 having broad width and small thickness and is secured so as to acommodate small radial rigidity and large tangential rigidity of the arm 5. In this manner, the thermal expansion of the bracket arm is absorbed, and the rotor 8 can endure against the tangential force due to the unbalance of the rotor 8, thereby improving the stability.
