Abstract

The invention relates to a propeller propelling plant with the controllable pitch. The propeller propelling plant comprises main propelling blades, a propeller hub, an oil cylinder and bolts. Paddle flanges are arranged outside the main propelling blades; the propeller hub is provided with a self-aligning ball bearing disc which is provided with a rotating groove; an eccentric pin is arranged in the rotating groove, and a deflection plate is arranged in the propeller hub. A piston rod is arranged in the oil cylinder; a push-pull rod is arranged in the piston rod; a coupling is arranged outside the piston rod and the push-pull rod. A first damping disc and a second damping disc are arranged on the outer wall of the push-pull rod; a first spring is arranged between the first damping disc and a protecting cover, and a second spring is arranged between the second damping disc and one end of a push-pull rod sleeve. The propeller propelling plant with the controllable pitch is good in damping effect, high in transmission efficiency, and conductive to prolonging the service life and improving the stability.

Description

technical field [0001] The invention relates to an adjustable pitch propeller propulsion device, which belongs to the technical field of propeller propulsion equipment. Background technique [0002] Propeller refers to a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There may be two or more blades connected to the hub, and the rear side of the blades is a helical surface or similar to a helical surface. A marine propeller, so it is widely used in the fields of navigation and aviation, and the variable torque propeller changes the output torque by changing the inclination angle of each blade of the propeller, that is, the propeller can be changed under the condition of constant speed. thrust. [0003] When the adjustable-pitch propeller propulsion device in the prior art is applied to the driving power device of the boat, the thrust generated by the water often causes the propeller to vibrate, causing devi...
