Abstract

The invention discloses a propeller drive mechanism, which is provided with a center shaft and a gearbox. The propeller drive mechanism is characterized in that the upper part of the center shaft is connected with a casing through a bearing, an upper gear, a lower gear and a side gear are arranged in the gearbox, a transverse shaft which is connected with the side gear is perpendicular to the center shaft, the side gear is respectively engaged with the upper gear and the lower gear, the lower gear is fixed on the center shaft and the upper gear is installed at the bottom of the casing. Since the structure is provided with a relatively centralized drive system, the manufacturing cost of a power system is reduced and an airplane has better mobility.

Description

A kind of screw propeller transmission device
Technical field
The present invention 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 hovering) and the maneuvering flight of heading unmodified, particularly can be in small size place vertical takeoff and landing.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, helicopter is lifted holder aloft, sustainer, main engine simultaneously also outputting power can offset antagonistic force under the different rotating speeds that the king bolt oar produces to the minor spiral oar of afterbody by the pitch of adjusting the 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.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of screw propeller transmission device is provided, 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 present invention, be provided with axis and tooth case, it is characterized in that described axis top is connected by bearing with sleeve pipe, be provided with in the described tooth case cog, lower gear and side gear, described side gear bonded assembly transverse axis is vertical with axis, described side gear respectively at cog, the lower gear engagement, described lower gear is fixed on the axis, and described cogging is installed on sleeve bottom.
Described tooth case outlet at bottom place is provided with down pipe.
The quantity of described 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
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of a kind of screw propeller transmission device of the present invention.
The specific embodiment
As shown in Figure 1, a kind of screw propeller transmission device of the present invention, be provided with axis 1 and tooth case 3, it is characterized in that described axis 1 top and sleeve pipe 2 are connected by bearing, be provided with in the described tooth case 3 and cog 4, lower gear 6 and side gear 5, described side gear 5 bonded assembly transverse axis 8 are vertical with axis 1, described 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.
Described lower gear 6 is fixed on the axis 1, and described cogging 4 is installed on sleeve pipe 2 bottoms.
Described tooth case 3 is installed on goes straight up on the body, tooth case 3 can independent rotation, for example tooth case 3 outlet at bottom places can be provided with down pipe 7, rotate around axis 1 by pipe 7 and tooth case 3 under the driven by motor like this, at this moment, the rotating speed of sleeve pipe 2 is determined by two kinetic factors, the one, 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 rotates around axis, finally make the controlled system of the rotating speed control of sleeve pipe 2, present 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.
