Electricity generation plant on-board ship - is powered from propeller drive-shaft via step=down gearwheel and rotor on same axle but in separate compartment

摘要

The generator rotor (5) and the step-down gear wheel (3) are on the same axle (9) and in the same housing (17, 18) which is divided into separate subcompartments by a separating wall (12) and the oil-tight seal (6). The oil-tight seal can surround the generator in an arrangement where the pole shoe of the rotor is fixed with its axis in prallel with the large wheel (3), the sealing being fixed to the housing and coming into effective contact with the front face of the toothed ring or an abutment surface on a side wall of the large wheel. ADVANTAGE - Quiet, low cost, space-saving electricity generation on ship.
