Abstract
The utility model relates to a rotor wing head mechanism for a single super-light type helicopter. The rotor wing head mechanism comprises a pair of rotor wing clamps, wherein rotor wing connecting pieces are arranged on the surfaces of the rotor wing clamps; double-disc bearings and a pair of rotor wing clamp central shafts are arranged inside the rotor wing clamps; a main seesaw is respectively arranged on each side of the opposite part of the rotor wing clamps; the two rotor wing clamps and the main seesaws on two sides are fixedly connected into one part through bolts; a main rotating shaft which penetrates through the two main seesaw plates are arranged on the two seesaw plates; through grooves for clamping main rotor wings are formed in the outer ends of the two rotor wing clamps; the two main rotor wings are symmetrically fixedly connected with the rotor wing clamps around a central point through bolts. The rotor wing head mechanism is smart in structure, light in weight, small in wind noise, precise and accurate to control, simple and firm in structure and durable and long-lasting, and does not need to be frequently repaired such as replacing transverse shafts.
Description
Technical field
The utility model relates to a kind of single microlight-type helicopter rotor head mechanism, especially little with air resistance, and that wind is made an uproar is little, control precisely, firm in structure, the rotor head mechanism that convenient disassembly is feature.
Background technology
In existing technology, material mold die casting for common rotor head, huge structure Heavy Weight, manufacturing cost is also relatively large, and structure is a transverse axis series connection for two rotor folders, and transverse axis is tiny, easily crooked in rotation, after cause vibrations greatly, often to need repairing to change transverse axis etc.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of resistance little, and that wind is made an uproar is little, control precisely, long-lived single microlight-type helicopter firm in structure rotor head mechanism.
The technical solution adopted in the utility model is: a kind of single microlight-type helicopter rotor head mechanism, and it has a pair of rotor folder, and the surface of rotor folder is provided with rotor folder connecting strap; Rotor underedge is installed double plate bearing and a pair of rotor folder center shaft, and respectively there is a main seesaw both sides that press from both sides relative position at rotor, by bolt, the main seesaw of two rotor folders and both sides is fixedly connected with in aggregates.On two main seesaws, there is main rotary shaft to pass through betwixt.The outer end of two rotors folder is provided with the groove of clamping main rotor, two main rotors by bolt by central point be fixedly connected on rotor folder.
The utility model delicate structure, lightweight, that wind is made an uproar is little, control precisely, simple in structure, firm, durable in use, does not need frequent maintenance, changes transverse axis etc.
Accompanying drawing explanation
Fig. 1 is birds-eye view of the present utility model.
Fig. 2 is the elevation drawing of Fig. 1.
In figure: 1, rotor folder, 2, main rotor, 3, rotor folder connecting strap, 4, main seesaw, 5, rotor folder center shaft, 6, main rotary shaft.
The specific embodiment
The utility model mainly by 1, rotor folder 3, rotor folder connecting strap 4, main seesaw 5, rotor folder center shaft 6, main rotary shaft etc. are combined into novel rotor head mechanism body part.By the controlling quantity of the joystick in driving compartment, finally make the rotor of helicopter reach the object of the positive and negative angle of attack.
The technical solution adopted in the utility model is: adopt the direct turning of high strength aviation aluminium to make a pair of rotor folder 1, smooth in appearance brightness attractive in appearance is high, the surface of rotor folder 1 is provided with rotor folder connecting strap 3, by controlling the amplitude that the swings up and down size of rotor folder connecting strap 3, cause rotor folder 1 to twist angle thereupon.1 li of installation double plate bearing of rotor folder and a pair of rotor folder center shaft 5, rotor folder center shaft 5 is disjunctor not, with special aviation bolt, respectively the main seesaw 4 of both sides is fixedly connected into integral body with it.Rotor folder center shaft 5 also adopts the turning of aviation aluminium to make, short and sturdy, is difficult for ruptural deformation.
On two main seesaws 4, there is main rotary shaft 6 to pass through betwixt.The outer end of two rotors folder 1 is provided with the groove of clamping main rotor 2, two main rotors 2 by bolt by central point be fixedly connected on rotor folder 1.
