A multifunctional emergency rudder steering device with a full-rotation rudder propeller

Abstract

The invention provides a multifunctional emergency steering device of a full-circle-swinging steering oar. The multifunctional emergency steering device comprises a bearing seat (3), a bearing (4), a transmission shaft (5) and an emergency gear (6), the lower portion of the bearing seat (3) is fixedly connected with a rotary unit cover plate (1), the bearing (4) is fixed in the bearing seat (3), the transmission shaft (5) and the bearing (4) are in interference fit, a hexagonal cylinder connector is arranged at the top of the transmission shaft (5), the emergency gear (6) is connected at the lower end of the transmission shaft (5) in a sleeved manner and is in transition fit with the transmission shaft (5), and the emergency gear (6) and a rotary supporting inner ring gear (4) are in meshed transmission. A force-applying rod is connected in a sleeved manner and rotated, and rotary torque can be applied on a rotary shaft to realize manual steering; after the emergency steering device is locked, the rotary shaft and a propelling unit can be further locked to realize a function of fixing an oar angle. The multifunctional emergency steering device is simple and compact in structure and complete in function, and steering control performance of the full-circle-swinging steering oar can be improved.

Description

Technical field [0001] The invention relates to an accessory part of a ship's full-slewing propulsion device, in particular to a multi-functional emergency rudder steering device of a full-slewing rudder propeller, belonging to the technical field of ships. Background technique [0002] The ship’s full-rotating rudder propeller eliminates the need for traditional rudder equipment, and uses the propeller and the propulsion device itself to form a rudder torque to achieve rudder turning. The rudder-propeller integrated device has a compact structure, which makes the ship more flexible and maneuverable. As a result, it has been more and more widely used. The existing full-rotation rudder propeller includes a control unit, a power unit, a rotation unit and a propulsion unit. Among them, the power unit includes a hydraulic motor, a reducer, and a drive gear, and the slewing unit includes a slewing unit cover, a slewing ring gear, a slewing ring, a slewing shaft, etc. The slewing shaf...

Problems solved by technology

[0004] However, the emergency rudder steering device of the above application still has obvious defects and deficiencies: First, an inner hexagonal counterbore is opened on the upper end (force application end) of the gear shaft, which weakens the strength of the gear shaft, which is very unfavorable for the gear shaft whose end bears a large torque load , and the processing of the inner hexagonal counterbore is complicated; the second is that the emergency steering device of the above application lacks the function of fixing the rudder angle, which makes it difficult for the ship to maintain the navigation direction under the action of a large external load, which affects the control performance of the ship
