Abstract

The utility model discloses a kind of speed reducing ratio dynamic structure of unmanned plane, motor bracket, lower casing, upper casing three are fixed together by two screws, shaft set is on motor bracket, motor gear and motor axis connection, motor is fixed on lower casing by motor bracket, while LED is fixed on the outside of lower casing, and driven gear is through shaft set on the cylinder of motor bracket, blade is arranged on driven gear, and slide plate is arranged on blade.Motor bracket fixed mechanism and driven gear mechanism for installing of the present utility model add the stationarity of speed reducing ratio dynamic structure, it is effectively prevented driven gear inclination, it ensure that the cooperation of driven gear and motor gear is smooth, so as to effectively reduce the loss of unmanned mechanomotive force;Motor bracket fixes LED mechanisms and effectively raises production efficiency, reduces production cost, and unique blade fixed mechanism effectively reduces the friction of blade and other parts, reduces the consume of unmanned mechanomotive force.

Description

A kind of speed reducing ratio dynamic structure of unmanned plane
Technical field
It the utility model is related to unmanned air vehicle technique field, the speed reducing ratio dynamic structure of particularly a kind of unmanned plane.
Background technology
Common unmanned plane speed reducing ratio dynamic structure is then will be driven through motor bracket by an elongated iron axle Gear is fixed on motor bracket, and blade is fixed on driven gear, and when motor rotates, motor gear drives driven gear, driven Gear drives blade by the friction of elongated iron axle and motor bracket;This common unmanned plane speed reducing ratio dynamic structure is without fixation LED structure and overall structure assemble complicated, the unmanageable easily error of precision, use rear degradation for a long time:Elongated iron axle With the extremely difficult control of driven gear assembly precision, easily fill during production askew, cause driven gear to coordinate with motor gear and have some setbacks, it is raw It is poor that the unmanned plane performance of output cannot be guaranteed uniformity;After this common unmanned plane usage time length, due to elongated iron axle with Friction increases the gap between two parts to motor bracket for a long time, causes the centre-to-centre spacing of two gears to change, complete machine Degradation;When high-speed flight strikes other objects, elongated iron axle is easily deformed unmanned plane, influences unmanned plane complete machine Energy.
Utility model content
A kind of the shortcomings that the purpose of this utility model is to overcome prior art, there is provided speed reducing ratio power of unmanned plane Structure.
The utility model uses following technical scheme to achieve the above object:A kind of speed reducing ratio dynamic structure of unmanned plane, Including slide plate, blade, rotating shaft, motor bracket, upper casing, lower casing, LED, motor, driven gear, motor gear, the motor branch Frame, lower casing, upper casing three are fixed together by two screws, and the shaft set is on motor bracket, motor gear and electricity Arbor is connected, and motor is fixed on lower casing by motor bracket, while the LED is fixed on the outside of lower casing, the driven tooth Wheel is through shaft set on the cylinder of motor bracket, and the blade is arranged on driven gear, and the slide plate is arranged on blade On, medium screw coordinates with rotating shaft fixes blade and driven gear.
Compared with prior art, the utility model has advantages below:Motor bracket fixed mechanism in the utility model The stationarity of speed reducing ratio dynamic structure is added with driven gear mechanism for installing, is effectively prevented driven gear inclination, It ensure that the cooperation of driven gear and motor gear is smooth, so as to effectively reduce the loss of unmanned mechanomotive force;Motor bracket Fixed LED mechanisms effectively raise production efficiency, reduce production cost, and unique blade fixed mechanism effectively reduces The friction of blade and other parts, reduce the consume of unmanned mechanomotive force.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is assembling schematic diagram of the present utility model.
In figure:1st, medium screw, 2, slide plate, 3, blade, 4, rotating shaft, 5, motor bracket, 6, upper casing, 7, lower casing, 8, LED Lamp, 9, motor, 10, screw, 11, driven gear, 12, motor gear.
Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1-2,1 a kind of, the speed reducing ratio dynamic structure of unmanned plane, including slide plate, blade, rotating shaft, motor bracket, Upper casing, lower casing, LED, motor, driven gear, motor gear, the motor bracket 5, lower casing 7, the three of upper casing 6 pass through two Screw 10 is fixed together, the mode of this fixing motor support ensure that motor bracket it is steady, with fuselage keeping parallelism, avoid Driven gear tilts the problem of also and then together tilting because of motor bracket;The rotating shaft 4 is sleeved on motor bracket 5, The mode of this fixed rotating shaft, effectively solves the problems, such as axes of rotation skew;Motor gear 12 and the axis connection of motor 9, motor 9 are logical Motor bracket is crossed to be fixed on lower casing 7, while the LED 8 is fixed on the outside of lower casing 7, this motor bracket fixes LED Production and assembly efficiency is greatly improved in mode, reduces production cost;The driven gear 11 is sleeved on motor through rotating shaft 4 On the cylinder of support 5, the assembling fixed form of this motor bracket, effectively solve the problems, such as that driven gear is tilted, shaken; The blade 3 is arranged on driven gear 11, and the slide plate 2 is arranged on blade 3, and medium screw 1 coordinates blade with rotating shaft 4 3 fix with driven gear 11, and the mode of this fixed blades can effectively reduce the friction of blade and other parts, reduce dynamic Power is lost, and can effectively prevent that blade from flying out fuselage.
Described above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality With new teaching, in the case where not departing from principle of the present utility model and spirit, the change that is carried out to embodiment, repair Change, replace and modification is still fallen within the scope of protection of the utility model.
