The invention discloses a marine fixed-pitch propeller type lateral propelling device which comprises a cylinder, a hydraulic valve group is arranged above the outer side of the cylinder, a hydraulic motor is arranged on the inner side of the cylinder, a hose assembly is connected between the hydraulic motor and the hydraulic valve group, and the output shaft end of the hydraulic motor is connected with a horizontally-arranged propeller shaft. The end, away from the hydraulic motor, of the propeller shaft is sleeved with a propeller hub, the propeller hub is connected with a plurality of propeller blades, the side face, close to the hydraulic motor, of the propeller hub is connected with a bearing cover, two tapered roller bearings are arranged in the bearing cover, and the side face, close to the hydraulic motor, of the bearing cover is connected with a motor cover arranged on the outer side of the hydraulic motor in a covering mode. A flow guide cover is arranged on the side, away from the hydraulic motor, of the hub. The hydraulic pump station has the beneficial effects that the hydraulic motor and the hydraulic valve group form the comprehensive hydraulic pump station, operation is flexible, installation and maintenance are convenient, and the fault rate is low; the hydraulic motor is directly connected with the propeller shaft, gear transmission is reduced, noise is low, the installation size is small, and the device is suitable for various ship types.
Description
technical field [0001] The invention relates to the technical field of ship lateral propulsion devices, in particular to a marine fixed-pitch propeller type lateral propulsion device. Background technique [0002] In order to further improve the maneuverability and maneuverability of ships, lateral thrusters are currently widely used on various ships. Lateral thrusters are installed in the cabin or in the transverse ducts of the ship to generate lateral thrust on the hull. Marine propulsion is an important part of marine power equipment. In traditional lateral propulsion, its drive motor (or other prime movers such as hydraulic motor, diesel engine, etc.) drives the drive shaft of the lateral thrust unit, and the drive shaft is driven by meshing bevel gears. The propeller shaft rotates. However, the structure connected with the propeller shaft through the gear has high noise, large volume, and requires a large installation space; at the same time, the operation flexibility...
