Abstract

The utility model discloses a propeller transmission mechanism which is provided with a central shaft and a gearbox and is characterized in that the upper part of the central shaft is connected with a sleeve through a bearing, an upper gear, a lower gear and a side gear are arranged in the gearbox, a transverse shaft connected with the side gear is vertical to the central gear, the side gear is meshed with the upper gear and the lower gear respectively, the lower gear is fixed on the central shaft, and the upper gear is arranged at the bottom of the sleeve. The propeller transmission mechanism has a more concentrated transmission system, so that the manufacture cost of a power system is reduced, and a plane has better maneuverability.

Description

A kind of screw propeller transmission device
Technical field
The utility model relates to a kind of parts of helicopter, specifically a kind of screw propeller transmission device.
Background technology
The outstanding feature of helicopter is to do low latitude (overhead several meters), low speed (from the beginning of hovering) and the maneuvering flight of heading unmodified, particularly can be in the VTOL of small size place.Because these characteristics make it have wide purposes and development prospect.Be widely used in attacking over the ground aspect military, machine fall land, weapon transports, logistics support, rescue of battlefield, reconnaissance patrol, commander's control, signal communication, antisubmarine clearance, electronic countermeasure etc.Aspect civilian, be applied to short-distance transport, medical aid, disaster relief lifesaving, emergency resuce, hanging device, geoexploration, protect a forest fire extinguishing, aerophotography etc.Personnel between offshore field and base and goods and materials transportation are importances of coml.
Helicopter engine drives rotor lift is provided in the prior art; Lift holder to helicopter aloft; Sustainer, main engine is the also minor spiral oar of outputting power to afterbody simultaneously, can offset the antagonistic force under the different rotating speeds that the king bolt oar produces through the pitch of adjustment minor spiral oar.This mechanism that big or small screw propeller is set at different parts can guarantee that helicopter carries out multiple action aloft; Accurately reach the intention of chaufeur; But this structure needs the relatively independent driving system of two covers, and inner power drive system is had relatively high expectations, and cost is also higher.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of screw propeller transmission device is provided, and it can only use a cover power drive system, has reduced manufacturing cost.
For solving the problems of the technologies described above, a kind of screw propeller transmission device of the utility model is provided with axis and tooth case; It is characterized in that said axis top is connected through bearing with sleeve pipe; Be provided with in the said tooth case cog, lower gear and side gear, said side gear bonded assembly transverse axis is vertical with axis, said side gear respectively at cog, the lower gear engagement; Said lower gear is fixed on the axis, and said cogging is installed on sleeve bottom.
Said tooth case outlet at bottom place is provided with down pipe.
The quantity of said side gear is 2.
After adopting such scheme, this structure has the driving system of comparatively concentrating, and has reduced the manufacturing cost of power system and has had maneuvering performance preferably.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of a kind of screw propeller transmission device of the utility model.
The specific embodiment
As shown in Figure 1, a kind of screw propeller transmission device of the utility model is provided with axis 1 and tooth case 3; It is characterized in that said axis 1 top and sleeve pipe 2 are connected through bearing; Be provided with in the said tooth case 3 and cog 4, lower gear 6 and side gear 5, said side gear 5 bonded assembly transverse axis 8 are vertical with axis 1, said side gear 5 respectively at cog 4, lower gear 6 engagements; Cog 4, lower gear 6 and side gear 5 are helical wheel, are the transmission of center cross helical wheel between them.
Said lower gear 6 is fixed on the axis 1, and said cogging 4 is installed on sleeve pipe 2 bottoms.
Said tooth case 3 is installed on goes straight up on the body, and tooth case 3 can independent rotation, and for example tooth case 3 outlet at bottom places can be provided with down pipe 7; Rotate around axis 1 through pipe 7 and tooth case 3 under the driven by motor like this; At this moment, the rotating speed of sleeve pipe 2 determines by two kinetic factors, the one, and lower gear 6 drives side gears 5 and further drives to cog and 4 sleeve pipe 2 is rotated; The 2nd, external impetus drives tooth case 3 and rotates around axis 1; And then drive transverse axis 8, side gear 5 around the axis rotation, and finally make the controlled system of the rotating speed control of sleeve pipe 2, demonstrate variable rotating speed.
Sleeve pipe 2, axis 1 are driven two coaxial screw propellers respectively, and such two screw propellers also different rotating speeds can occur, thereby make different actions aloft.
