Abstract
The utility model relates to a transmission mechanism, in particular to a transmission mechanism for a model helicopter, which comprises an electric motor and a gear set. The gear set comprises a master bevel gear, an upper bevel gear and a lower bevel gear; and the three bevel gears are meshed together and connected with the electric motor through transmission shafts. Compared with the prior art, the utility model has the advantages of simple structure, fewer mechanical parts, low energy consumption and stable transmission of the gear set.
Description
Technical field
The utility model relates to a kind of driving mechanism, particularly the model helicopter driving mechanism.
Background technique
The driving mechanism of present model helicopter, a kind of is to be rotated by two propeller cavitations of two groups of motor drives; A kind of is the working flight of being taken turns to finish model plane by multiple sets of teeth by one group of motor.These two kinds of transmission systems are because to drive parts more, not only cause unbalancely easily, and have increased energy consumption.
Summary of the invention
Goal of the invention of the present utility model is at the existing defective that the model plane transmission component is many, energy consumption is big, and a kind of simple in structure, model helicopter driving mechanism that energy consumption is little is provided.
For achieving the above object, the utility model is by the following technical solutions: a kind of model helicopter driving mechanism, comprise motor and gear train, and described gear train comprises master bevel gear, goes up umbrella gear and following umbrella gear, the three meshes together, and is connected with motor by transmission shaft.
Compared with prior art, the utility model is simple in structure, and mechanical part is few, and energy consumption is low, and the gear train transmission is stable.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: interior drive link 1, internal propeller 2, external spiral oar 3, outer drive link 4, last umbrella gear 5, master bevel gear 6, transmission shaft 7, motor 8, casing 9, following umbrella gear 10.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to accompanying drawing, gear train in the present embodiment is by master bevel gear 6, last umbrella gear 5 and following umbrella gear 10, the three meshes together, last umbrella gear 5 and following umbrella gear 10 are oppositely arranged, and are provided with master bevel gear 6 between the two, and master bevel gear 6 is connected with the motor 8 that is fixed on casing 9 inside by transmission shaft 7, internal propeller 2 and external spiral oar 3 place casing 9 outsides, interior drive link 1 places outer drive link 4 inside, and the two passes casing 9, is connected with following umbrella gear 10 with last umbrella gear 5.The upper end of interior drive link 1 and internal propeller 2 usefulness bolts are connected and fixed, and umbrella gear 5 is passed in its lower end, after circumferentially fixing with following umbrella gear 10, inject in the lower casing 9; The upper end of outer drive link 4 and external spiral oar 3 usefulness bolts are connected and fixed, and its lower end is fixed in the upper surface of umbrella gear 5.
Working principle of the present utility model is: when motor 8 clockwise rotated by transmission shaft 7 driving master bevel gears 6, umbrella gear 5 was gone up in meeting drive simultaneously and following umbrella gear 10 rotates by opposite direction: upward umbrella gear 5 clockwise rotates by outer drive link 4 drive external spiral oars 3; Following umbrella gear 10 drives internal propeller 2 by interior drive link 1 and rotates counterclockwise.
Claims (1)
1, a kind of model helicopter driving mechanism comprises motor and gear train, it is characterized in that: described gear train comprises master bevel gear, goes up umbrella gear and following umbrella gear, and the three meshes together, and is connected with motor by transmission shaft.
