Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0028] The structural device based on the ship's whale tail wheel propeller controlled by stepping motor provided by the invention, its structure is as follows Figure 1 to Figure 4 Shown: It includes the power transmission mechanism organically combined, the drive mechanism that drives the blades to swing, the anti-winding mechanism, the gear lubrication mechanism, the waterproof mechanism, and the support mechanism. These mechanisms cooperate with each other to make the rotary wheel rotate and the blades swing to achieve It can maintain high propulsion efficiency under different working conditions, improve the utilization rate of the output power of the main engine, and save fuel consumption.

[0029] The power transmission mechanism is arranged in the pod housing, and the power transmission mechanism consists of a vertical shaft 4, a ro...

Abstract

The invention relates to a structural device of a ship whale tail wheel propeller based on stepping motor control. The device is mainly composed of a pod shell, a runner (5) arranged in the pod shell, a plurality of blades (2) connected with the two sides of the runner (5), a drive mechanism driving the runner (5) to rotate, and a drive mechanism driving the blades (2) to swing. The pushing force can be changed by adjusting the blade swinging rule and the rotating speed of the runner according to different work conditions, a propelling device can run with the high propelling efficiency, the utilization rate of the output power of a main machine is increased, and beneficial effects are achieved in the aspect of ship energy saving.
