Abstract
The utility model discloses a coaxial planetary transmission case of a model helicopter, wherein the axis of a motor rotating shaft as power input and the axis of a wing spindle as output are on the same axis; a ring gear is connected at the rotating shaft; an inner gear of the ring gear is connected with a plurality of planetary lower gears; each planetary lower gear is coaxially connected with a planetary upper gear; each planetary gear group is parallel to the rotating shaft; the spindle is connected with an output gear; and the planetary upper gears are connected with the output gear to form a multipoint contact transmission mechanism which leads the spindle to rotate more stably.
Description
Technical field
The utility model is meant the coaxial planetary transmission case of a kind of model copter especially about a kind of model copter transmission mechanism.
Background technology
The transmission mechanism of existing model copter is a non-coaxial, as shown in Figure 1, 2; This kind structure by motor (brushless electric machine) as power resources, must conduct on two oar wings 13 of model copter from the power of engine or battery, need see through the rotation that a deceleration device drives a main shaft 1 therebetween, so the axes sleeve at motor 10 is connected to a pinion 12, the lower end of main shaft 1 is for being connected to a gear wheel 11, the upper end of main shaft 1 is for being connected to wing 13, so allow pinion 12 and gear wheel 13 toe joint mutually, just can become the Contact Transmission mechanism of single-point type, one contact point is only arranged therebetween, and be very tall and big wing on the main shaft, when horsepower is big more, relatively the diameter of gear wheel is also big more, reached more than the 120mm, relatively have influence on the stability of each spare part, its may because of a misoperation or maintain improper, even aloft external force, allow wherein arbitrary element damage fast, through looking into its reason, all be to come from the instability of single-point transmission and the consume of energy transmission or the like reason, for the article of more realistic demand are provided, the creator researches and develops, to solve the existing problem that easily produces that goes up of using.
The utility model content
Main purpose of the present utility model is to provide a kind of model copter coaxial planetary transmission case, solve also the rocking built on the sand of existing single-point toe joint, easy tooth-breaking, easy to wear and gear wheel and be difficult for situations such as making, precision be not good, use the mechanism of multiple spot toe joint instead, just can reach firm transmission and the requirement that improves torsion output, also can improve the convenience of use and the trouble of reduction maintenance etc., allow whole transmission more meet the requirement of efficient.
For reaching above-mentioned purpose, structure of the present utility model is: wherein as the axle center of the rotating shaft of the motor of power input and the same axis in axle center as the main shaft of the wing of output, connect a rim gear wheel in rotating shaft place again, several planet lower gears that the internal tooth of rim gear wheel is connected to, each planet lower gear is for cogging with being connected with delegation's star, each planetary gearsets is the parallel shaft setting, be connected to an output gear on the main shaft, allow each planet cog and output gear joins, to form the mechanism of multiple spot Contact Transmission, allow main shaft more stably rotate.
For making your juror can further understand the utility model is to reach technology, means and the effect that predetermined purpose is taked, now for a preferable feasible embodiment, and conjunction with figs. describes in detail as after, believe the purpose of this utility model, feature and advantage, go deep into and concrete understanding when getting one thus.

The specific embodiment
Extremely shown in Figure 5 as Fig. 3, be the coaxial planetary transmission case of a kind of model copter of the utility model, wherein as the axle center of the rotating shaft of the motor 30 of power input and the same axis in axle center as the main shaft 4 of the wing of output, connect a rim gear wheel 31 in rotating shaft place again, several planet lower gears 32 that the internal tooth of rim gear wheel 31 is connected to, each planet lower gear 32 cogs 34 for same fixed axis 33 is connected to a planet, each planetary gearsets 32,34 is the parallel shaft setting, be connected to an output gear 41 on the main shaft 4, allowing each planet cog 34 joins with output gear 41, to form the mechanism of multiple spot Contact Transmission, allow main shaft 4 more stably rotate.It shown in the figure setting of stage type, just fixed axis 33 is provided with two pairs planetary gearsets, remove planet lower gear 32 (being required to be gear wheel) originally, planet cogs and 34 (is required to be pinion, and no longer output), another planet cogs and (is required to be gear wheel, it can join with another output gear, and each another planet 36 outer another rim gear wheels 35 that are with that cog) 36, another planet cogs and 38 (is required to be pinion, replace original gear 34 as new output), last pinion among the figure is gear 34 above, last gear wheel is located another set output gear of below (not expression among the figure for being used for output gear 41 (being required to be gear wheel this moment), be required to be pinion this moment) effect of joining, below analogize.Show in addition among Fig. 3 and can contain a driver shell 39 (shown in the dotted line) that the state of its transmission as shown in Figure 4, and is and less because of output gear 41, can't see among the figure; Whole implementation as shown in Figure 5.And the fixed axis with four among the figure shows, also should comprise when it is two, three, five, six.Wherein each gear is helical teeth or commutating tooth.Implementing all axles in this all rotates towards a logical direction with gear.This mechanism uses mainly as slowing down.
Structure in sum, the gear structure of the utility model utilization multiple spot contact, round power shaft and output shaft, become intermediary's transmission mechanism therebetween, form simple speed change gear, make transmission more precise and stable, operate more smooth and easyly, particularly main shaft more is difficult for rocking, and more increases the enjoyment of using, so good usability can be provided, be one fully with existing different mechanism.
The above is the detailed description of preferred embodiment of the present utility model and graphic, be not to be used for limiting the utility model, all scopes of the present utility model should be as the criterion with following claim, the embodiment and the approximate construction of the spirit variation similar with it of all claims all should be contained among the utility model.
