Abstract

The invention discloses a ship pod type propeller which comprises a pod housing, a propeller body and a propeller shaft. The pod housing is installed on a ship body through a rotating bearing. The propeller shaft is fixedly installed on a bearing pedestal of an inner cavity of the pod housing through a bearing in the pod housing. The propeller body outside the pod housing is installed at one end of the propeller shaft. The propeller shaft is driven by a permanent magnetic synchronous motor. Modularized design is adopted, the ship pod type propeller is convenient to manufacture, high in installation precision and large in output power, and a driving device is small in size.

Description

technical field [0001] The invention relates to the field of ship propulsion, in particular to a ship pod propeller. Background technique [0002] The propeller is an important part of ship power equipment. Among all kinds of propellers, the pod propeller is indeed one of the best. Although the pod propeller has high efficiency of electric propulsion, small vibration and low pollution technology Advantages, it has been applied to diving operation supply ships, oil drilling platforms, supply ships, shuttle tankers and ro-ro ships, icebreakers and some military ships. [0003] Pod propulsion, also known as POD propulsion, is a new type of ship propulsion device that integrates propulsion and steering devices. The pod propeller places the propulsion motor outside the cabin and is directly connected to the propeller, which can rotate horizontally within 360° to achieve vector propulsion. Generally, it is mainly composed of a built-in drive motor module, a propeller module, a h...
