Abstract
The invention relates to a gear-driven propeller of a helicopter, belonging to the technical field of power plant propulsion. The propeller is of a frame structure composed of a support frame and a shell, a gear ring and a shaft sleeve are fixedly connected together by virtue of multiple propeller blades in each propeller gear, a power shaft drives the propeller gear arranged on a propeller supporting shaft to rotate by virtue of a driving gear, the propeller supporting shaft and the frame structure are in permanent connection, and a weight is suspended at the lower end of the propeller supporting shaft. The device combining the propeller and a drive mechanism has the following advantages: the diameter of the propeller is small, and the exterior is provided with a protection support frame to achieve an anti-collision function, thus the device can take off and land on a common road; the propeller is provided with multiple blades and is of an umbrella type, thus the slow descending function of a parachute can be realized when the device stops in the air; the blades are thin and light, the noise is less, and the vibration is small, thus the fatigue of personnel onboard is reduced; the bearing capacity is changed into four points of a propeller protection frame from one point of the traditional helicopter, thus a load can be born uniformly; and the structure is simple, the operation is flexible, the propulsive efficiency is high, and the device is safe and reliable and is convenient for maintaining.
Description
Technical field
The present invention relates to a kind of Helicopter Gear Transmission screw propeller, belong to engine installation Push Technology field.
Background technology
Existing helicopter screw propeller blade is longer, the shared space that has living space and occupy of revolving vane much larger than fuselage,, needing broader air route and bigger hardstand, this also directly influences helicopter to miniaturization, the development of lightness aspect.Electronic helicopter screw propeller is employed in installs four electric screw paddle structures on the circular frame, though its structure is simple, turn to flexibly, and maneuvering performance, motor weight is big, can influence the Combination property of complete machine.
Summary of the invention
To the problem that exists in the above-mentioned prior art, the present invention proposes a kind of Helicopter Gear Transmission screw propeller.This screw propeller should overcome the shortcoming of major diameter propeller blade, adopts minor diameter multiple propeller unitized construction, improves the Combination property of complete machine, for miniaturization, the lightness of helicopter are opened up a new road.
The technical scheme that the present invention adopts is: a kind of Helicopter Gear Transmission screw propeller, it mainly comprises a dynamical axis and screw propeller.It also comprises a framed structure that is made up of a plurality of bracing frames and shell; Said screw propeller adopts 2-4 screw propeller gear, and each screw propeller gear adopts 8-40 propeller blade to be fixed together gear ring and axle sleeve, and shape is like umbrella shape; Between gear ring and framed structure, be provided with thrust baring; Said dynamical axis is through the screw propeller gear rotation of driving gear drive installation on the screw propeller pivot shaft, and the screw propeller pivot shaft becomes captive joint with framed structure, and hangs weight in the lower end.
Said screw propeller gear is provided with miniature gears in the position near shell, and miniature gears is installed on the pinion shaft that is fixed together with said framed structure.
Said framed structure adopts individual upward convex framework of 2-4 and the individual convex framework down of 2-4 to be connected with shell, and each convex framework adopts the individual bracing frame that bends to arc of 8-16 to link together.
Said thrust baring is arranged on the place, last plane and the lower plane place of gear ring.
The invention has the beneficial effects as follows: this Helicopter Gear Transmission screw propeller adopts a framed structure that is made up of bracing frame and shell; Each screw propeller gear adopts more propeller blade to be fixed together gear ring and axle sleeve; Dynamical axis is through the screw propeller gear rotation of driving gear drive installation on the screw propeller pivot shaft; The screw propeller pivot shaft becomes captive joint with framed structure, and hangs weight in the lower end.The device that above-mentioned screw propeller and transmission device combine has following advantage: diameter of propeller is little, and the outside is provided with protection supporting frame, and anticollision can landing on average highway; Blade is many, is umbrella shape, and when shutting down in the air, that can play parachute slowly falls effect; Blade is frivolous, and noise is low, vibrates for a short time, alleviates the personnel's of seizing the opportunity fatigue; Bearing capacity is by 4 points that a bit become the screw propeller protective frame of conventional helicopters, and bearing load is even; Simple in structure, flexible operation, propulsion coefficient is high, and is safe and reliable, and maintaining is convenient.
