Description
Technical Field
The application relates to the technical field of underwater equipment, in particular to a propeller and a manufacturing method thereof.
Background
A Propeller (Propeller) is a device that converts any form of energy into mechanical energy. Thrust is generated by rotating blades or by injecting air (water). Can be used to drive a vehicle forward or as a power source for other devices such as a generator.
Propeller thruster, short for propeller. The propeller is arranged on the propulsion shaft below the waterline at the tail part of the boat, the propulsion shaft is driven by the main engine to rotate together, water is sucked from the suction surface of the paddle and discharged from the discharge surface, and the boat is pushed to advance by using the reaction force of the water. The propellers are divided into fixed-pitch propellers and adjustable-pitch propellers.
A fixed pitch propeller. Consists of a hub and blades. The number of the blades is generally 3-4. The part of the blade close to the hub is called a blade root, the outer end is called a blade tip, the front side is called a leading edge, the rear side is called a trailing edge, the propeller disc faces the stern and is called a discharge surface, and the propeller disc faces the bow and is called a suction surface. A circular guide pipe is additionally arranged on the outer edge of the fixed-pitch propeller, namely the guide pipe propeller. The duct may improve the propulsion efficiency of the propeller, but the reversing performance is poor. Ducted propellers can be divided into fixed and rotatable types. The fixed ducted propeller increases the turning diameter of the boat, and the rotatable ducted propeller can improve the turning performance of the boat.
A propeller with adjustable pitch. The propeller is driven to rotate by a crank connecting rod mechanism in the propeller hub, and the propelling power and the propelling direction of the propeller can be changed by changing the angle of the propeller blade under the condition of not changing the rotating speed and the running direction of the propelling shaft. The propeller has simple structure, reliable work and higher efficiency, and is a main propeller of the boat. The propellers of modern boats mostly adopt structural forms such as large disc surface ratio, moderate lateral inclination, radial unequal screw pitch, more blades and the like so as to reduce cavitation, ablation, noise and overlarge exciting force which are possibly generated when the propellers work in a stern uneven wake field. Some high speed boats have supercavity wing propellers. The air propeller for the full-lift air cushion traffic boat is similar to a fixed-pitch propeller, and the boat is pushed to advance by the reaction force of air.
At present, waterproof thrusters encapsulated by glue are basically combined by metal materials, plastic materials or rubber materials and the injected sealing glue so as to achieve the sealing effect. The propeller is basically partially encapsulated, and in an environment with thermal expansion and cold contraction or pressure change, the shrinkage rate of the sealant is different from that of a metal material, a plastic material and a rubber material, so that the bonding layer fails to work, and water leakage is caused.
The statements in this background section merely disclose technology known to the inventors and do not, of course, represent prior art in the art.
