Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0031] figure 1 It is a structural schematic diagram of a sealing device of a pod propeller in the related art, such as figure 1 As shown, the sealing device of the pod propeller includes a seal 10 and a connecting ring 20, the annular seal 10 is annular and is fitted on the paddle shaft a0 of the pod propeller, and one end of the seal 10 passes through the connecting ring 20 It is fixedly connected to the bulkhead 30 of the pod, thereby fixing the seal 10 outside the bulkhead 30 of the pod. A plurality of first sealing rings 40 close to the paddle shaft a0 are installed on the inner wall of the sealing member 10, and the gap between the bulkhead 30 of the pod and the paddle shaft a0 is sealed through the first sealing rings 40 to...

Abstract

The disclosure provides a sealing device for a pod propeller, which belongs to the technical field of ship propulsion. It includes a sealed cabin, a sealed assembly, a pusher and a sleeve, and the bulkhead of the sealed cabin has a first installation hole and a second installation hole for installing the paddle shaft of the pod propeller. The push cylinder is coaxially inserted into the first installation hole, and the first end of the push cylinder is located in the sealed compartment. The seal assembly includes a connecting ring and two seals, the first seal ring is arranged on the inner wall, the two seals are coaxially connected on both sides of the seal ring, one of the two seals is coaxially located in the push cylinder and The push cylinders are attached to each other, and the connecting ring is connected with the push cylinders. The connecting ring and the two seals are coaxially sleeved on the sleeve. There is a first section on the outer wall of the sleeve. The seal located outside the push cylinder is sleeved on the first section, and the first section is sealed with the first sealing ring. Cooperate. The sealing device can reduce the maintenance frequency and cost of the pod thruster.

Description

technical field [0001] The present disclosure relates to the technical field of ship propulsion, in particular to a sealing device for a pod propeller. Background technique [0002] The pod propeller puts the propeller drive motor in a pod that can rotate 360° and hangs under the ship, integrating the propulsion device and the steering device, which improves the maneuverability and ice-breaking performance of the ship operating in the ice area. The pod propeller usually needs to be provided with a sealing device between the propeller shaft and the propeller protruding from the pod to prevent seawater and impurities from penetrating into the pod and ensure the normal operation of the propeller. [0003] The sealing device in the related art usually includes an annular seal set on the paddle shaft, the seal is fixedly connected to the outside of the pod, and the inner wall of the seal is installed with a first sealing ring that is close to the outer surface of the paddle shaft...
