Embodiment Construction
[0018] The present invention designs an adjustable-pitch full-rotation rudder propeller device. Under the condition of constant diesel engine speed, the thrust and speed of the rudder propeller can be changed by changing the pitch of the propeller.
[0019] Adjustable pitch type full-turn rudder propeller device, such as figure 1 , figure 2 As shown, it includes a rudder column 1, a rudder hydraulic system 12 and a pitch hydraulic system 13. The rudder column 1 is rotatably supported on the flange. The large gear 3 and the steering hydraulic motor 4 are fixed on the flange, the output shaft of the steering hydraulic motor 4 is drivingly connected with the input shaft of the planetary reducer 5, and the output shaft of the planetary reducer 5 is installed with the driving pinion 6, the driving pinion The gear 6 is meshed with the large rotary gear 3, and the large rotary gear 3 is also meshed with the reduction gear 7, and the reduction gear 7 is provided with a feedback devi...

The invention relates to an adjustable pitch type rudder propeller device. A lower gear case is fixed at the lower part of a steering stand column; a rotating gearwheel is mounted at the upper part of the steering stand column; a steering hydraulic motor is connected with a planetary reducer; a driving pinion on the planetary reducer is meshed with the rotating gearwheel which is meshed with a reduction gear; a feedback device, a helm angle indicator and a control handle on the reduction gear are connected with an electrical control unit; an oil line of the steering hydraulic motor is connected to a steering hydraulic system which is connected with the electrical control unit; a hydraulic pitch adjusting system is connected with the electrical control unit and a drive hydro-cylinder; a piston of the drive hydro-cylinder is connected with a guide frame; a crank disc is mounted on the guide frame; oar blades are mounted on the crank disc; a rocker arm component on the drive hydro-cylinder is connected with a pitch feedback device which is connected with a displacement sensor; and the displacement sensor is connected with a pitch indicator and the electrical control unit. The thrust and the navigational speed of the rudder propeller are changed through changing the pitch of a propeller.
Description
technical field [0001] The invention relates to an adjustable pitch type full-rotation rudder propeller device, which belongs to the technical field of ship full-rotation rudder propellers. Background technique [0002] The marine full-turn rudder propeller device is a Z-shaped transmission device, the main function is to transmit the power from the diesel engine to the rudder propeller through the high-elastic coupling, short intermediate shaft, universal joint shaft, long intermediate shaft, universal joint shaft, and clutch ; The rudder propeller transmits the power to the propeller through the upper gear pair, the intermediate transmission shaft, and the lower gear pair to generate thrust; at the same time, the electro-hydraulic control system is instructed to control the lower gear box with the propeller, and it can rotate freely to the left or right without restriction. The thrust of the propeller can act in any direction, so as to obtain the best cooperation of propul...
