A carrying and guiding spider for the support of a rotor of a vertical electrical machine contains two different kinds of arms (6, 16) whereby the one kind of the arm (6) is supported on the foundation (12) in a sliding manner and forms acute angles (+A) in a circumferential direction with a radial line (17) of the clamping point (6') and the other kind of the arm (16) is rigidly connected with the foundation (12) and forms the acute angles (-A) in the opposite circumferential direction with the radial line (17) of the clamping points (16'). The advantage of this solution lies in that the carrying and guiding spider is symmetrically subjected to the load in the axial direction so that there is no torsional moment. At the same time, this construction permits the centering and the free expansion of the central body. |
