Abstract
The utility model discloses a kind of spindle gearings of unmanned plane, the main shaft being connect including driving motor and with propeller, the driving motor is equipped with output shaft, unilateral bearing is arranged on output shaft, output shaft is connected with output synchronous pulley by unilateral bearing, main shaft is connected with driving synchronous pulley, exports and is equipped with drive coordination band between synchronous pulley and driving synchronous pulley.The utility model output sleeve is equipped with unilateral bearing, the rotating speed of output shaft is higher, the torque that it is transmitted is smaller, therefore the torque that unilateral bearing is born is smaller, to ensure that the torque endurance of unilateral bearing, unilateral bearing can be used compared with small dimension size, be conducive to mitigate weight, while reducing repair manufacturing cost.
Description
Technical field
The utility model belongs to unmanned helicopter field, more particularly to a kind of spindle gearing of unmanned plane.
Background technology
Rotor wing unmanned aerial vehicle, also referred to as unmanned helicopter, its construction is fairly simple, and price is also cheaper, even more important
It is that it does not need emission system at all, moreover it is possible to VTOL more can freely hover, and flexibility of flying is quite superb,
It can fly with various speed, with the air route of various flight profile, mission profiles.In general flight quality, it can also show that " two is small
One is high " important feature：Chatter is small, noise is small, and Reliability comparotive is high.Therefore, in the country of Helicopter Technology prosperity, nobody drives
Helicopter is sailed to begin to develop very early.For example, the Kaman company in the U.S. just once releases pilotless helicopter early in the fifties, and
And there are some models to put into the practice stage.
Unmanned helicopter relies on propeller spiraling, propeller to be connected with main shaft, driving gear is connected on main shaft, main
It is equipped with unilateral bearing between axis and driving gear, since main shaft Moment is larger, in order to ensure the transmission of torque, is used single
Larger to bearing specification size, this just brings following defect：Unilateral bearing specification is larger so that weight increases, and is not easy to
Light-weight design；Unilateral bearing transmission torque is larger, and load is high, fragile, and cost is high, manufactures with regard to maintenance cost height.
Utility model content
In order to overcome the deficiencies of the prior art and there are the problem of, the utility model provides a kind of spindle drive dress of unmanned plane
It sets, simple in structure, power, which transmits, to be stablized, and production cost is low.
The utility model is achieved through the following technical solutions：
A kind of spindle gearing of unmanned plane, including driving motor and the main shaft that is connect with propeller, the driving electricity
Machine is equipped with output shaft, is arranged with unilateral bearing on output shaft, output shaft is connected with output synchronous pulley, main shaft by unilateral bearing
It is connected with driving synchronous pulley, exports and is equipped with drive coordination band between synchronous pulley and driving synchronous pulley.
The top and bottom of the output synchronous pulley are connected separately with upper flange disk and lower flange disk, drive coordination band position
Between upper flange disk and lower flange disk.
The unilateral bearing is needle-type unilateral bearing.
The upper flange disk and lower flange disk are equipped with connecting hole, export synchronous pulley upper and lower side be individually fixed in it is convex
In the connecting hole of edge disk and lower flange disk.
It is equipped with structure hole on the upper flange disk and lower flange disk.
The utility model output sleeve is equipped with unilateral bearing, and the rotating speed of output shaft is higher, and the torque transmitted is smaller, therefore single
The torque born to bearing is smaller, to ensure that the torque endurance of unilateral bearing, unilateral bearing can be used compared with small dimension ruler
It is very little, be conducive to mitigate weight, while reducing repair manufacturing cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the enlarged structure schematic diagram at A in Fig. 1.
In figure：1- driving motors, 2- output shafts, 3- main shafts, 4- unilateral bearings, 5- export synchronous pulley, and 6- drivings synchronize
Belt wheel, 7- drive coordination bands, 8- upper flange disks, 9- lower flange disks.
Specific implementation mode
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments to the utility model make into
One step is described in detail.
As depicted in figs. 1 and 2, a kind of spindle gearing of unmanned plane, including driving motor 1 and connect with propeller
Main shaft 3, driving motor 1 are equipped with output shaft 2, are arranged with unilateral bearing 4 on output shaft 2, output shaft 2 is connected by unilateral bearing 4
There are output synchronous pulley 5, main shaft 3 to be connected with driving synchronous pulley 6, exports and be equipped between synchronous pulley 5 and driving synchronous pulley 6
Drive coordination band 7.Driving motor 1 drives output shaft 2 to rotate, and output shaft 2 drives output synchronous pulley 5 to revolve by unilateral bearing 4
Turn, output synchronous pulley 5 is driven by drive coordination band 7, and driving synchronous pulley 6 rotates, and driving synchronous pulley 6 drives main shaft 3
Rotation, main shaft 3 drive propeller rotation.Unilateral bearing 4 is needle-type unilateral bearing, power transmission more reliable.
The top and bottom of output synchronous pulley 4 are connected separately with upper flange disk 8 and lower flange disk 9,7, drive coordination band
Between upper flange disk 8 and lower flange disk 9, upper flange disk 8 and lower flange disk 9 play position-limiting action to drive coordination band 7.On
Flange 8 and lower flange disk 9 are equipped with connecting hole, the upper and lower side of output synchronous pulley 4 be individually fixed in upper flange disk 8 and under it is convex
It is easy to connect in the connecting hole of edge disk 9.It is equipped with structure hole on upper flange disk 8 and lower flange disk 9, is convenient for light-weight design.
Above-described embodiment is the preferable realization method of the utility model, is not the restriction to the utility model, not
Be detached from the utility model inventive concept under the premise of, it is any it is obvious replacement the scope of protection of the utility model it
It is interior.
