Title:
二重反転プロペラ装置とこれを用いた船舶
Document Type and Number:
Japanese Patent JP6752361
Kind Code:
B2
Abstract:
The boss of a front propeller (2a) is fixed to a propeller shaft (5), and the boss of a rear propeller (2b) is supported by the propeller shaft (5) so as to be freely rotatable about the axis (Z-Z) of the propeller shaft (5). A reversal mechanism (10) has a contra-rotating gear device (20) and a reverse torque fixing device (40). The contra-rotating gear device (20) is accommodated in the boss of the rear propeller (2b) and reverses the rotation direction of the propeller shaft (5) to drive the rear propeller (2b). Furthermore, the contra-rotating gear device (20) is supported by the propeller shaft (5) so as to be rotatable about the axis (Z-Z). The reverse torque fixing device (40) supports a portion (carrier 30) of the contra-rotating gear device (20) and resists reverse torque about the axis (Z-Z).
