Abstract

The invention provides a nacelle type propeller based on gyroscopic precession, and belongs to the field of ship equipment. The nacelle type propeller based on gyroscopic precession comprises a propeller, a casing, a hydraulic control valve, a nacelle main shaft, a heavy block, a hydraulic motor, a transmission shaft and a hydraulic cylinder, wherein the upper part of the casing is provided with the nacelle main shaft, the rotating shaft is arranged inside the casing, the left end of the rotating shaft is provided with the propeller, the right end of the rotating shaft is provided with the hydraulic motor, the heavy block is sheathed on the rotating shaft, the hydraulic cylinder is fixedly arranged on the rotating shaft, and the hydraulic cylinder and the heavy block are mutually connected. The invention provides the nacelle type propeller utilizing the gyroscopic precession theory for realizing the steering direction change, the steering direction is directly determined through the direction of the heavy block deviating from the main shaft, the structure is greatly simplified, meanwhile, the direct driving through the hydraulic motor is realized, a complicated mechanical structure is omitted, and the nacelle type propeller has the characteristics that the structure is simple, and the use is convenient.

Description

technical field [0001] The invention relates to a pod-type propeller based on gyro precession, in particular to a pod-type propeller which utilizes gyro precession theory to realize steering change, and belongs to the field of ship equipment. Background technique [0002] An underwater pod-type propeller propulsion ship, which is to install an underwater pod on the bottom of an existing ship or boat, and a pedal mechanism is installed in the pod, and the propeller is driven by a conical bevel gear. Heavy, which improves the stability of the boat. The pod propeller can propel the propeller in a 360-degree direction, which improves the flexibility of the ship. However, the current control system is complicated and the mechanical structure is complicated, which affects its application and development, and it is an urgent problem to be solved. Contents of the invention [0003] The object of the present invention is to provide a pod-type propeller based on gyroscopic precess...
