The power packages further include gear wheel axle sleeve and thrust bearing, and the gear wheel axle sleeve is fixed in motor gear wheel, and the thrust bearing is placed in gear wheel axle sleeve.
The power packages are also further provided with unilateral bearing and collar bush, and unilateral bearing is placed in thrust bearing, and main shaft is placed in unilateral bearing, and the main shaft runs through collar bush, unilateral bearing, thrust bearing and gear wheel axle sleeve.
The power packages still further comprise main belt wheel cap, and driving pulley is placed on driving pulley lid.The main belt wheel cap and driving pulley are fixed on main shaft through collar bush.
Power driving module still further comprises pre- bearing up pulley, and it passes through pre- bearing up pulley fixed mount and is fixed on mainboard frame.
The empennage gear unit includes synchronous pulley and caudal wing shaft, and the synchronous pulley is fixed on caudal wing shaft.
The empennage gear unit still further comprises empennage belt foreign steamer and empennage fixes lid, and empennage belt foreign steamer is fixed lid and is fixed together with synchronous pulley and caudal wing shaft by empennage.
Described week restraining Timing Belt one end is placed on driving pulley, and its other end is placed on synchronous pulley.
Compared with prior art, driving member of the invention drives the kind of drive of empennage using week restraining Timing Belt, compensate for the drawbacks of axle transmission is easily damaged, not easy-maintaining, assembly technical requirement is high.And driving pulley is placed on the new paragon in motor gear wheel, the volume of whole machine is reduced, alleviate weight.And have unilateral bearing in motor gear wheel, and helicopter can be made slowly to put out because of fortuitous event, reduce the damage of aircraft.
To make the present invention easier to understand, a kind of specific embodiment of the power driving module of model plane of the invention is expanded on further below in conjunction with accompanying drawing.
Description of the drawings
Fig. 1 is the structural representation of the power driving module of model plane of the present invention.
Fig. 2 is the decomposition texture schematic diagram of the power driving module power packages of model plane of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention will be further described.
Power driving module of the present invention 100 is installed in the fuselage main body of model plane and urosome, constitutes the force piece of model plane.It includes power packages 1, empennage gear unit 3 and driving member, and empennage gear unit 3 and power packages 1 are respectively arranged in driving member two ends.The work of empennage gear unit 3 is driven by power packages 1.
Power packages 1 include motor gear wheel 11, driving pulley 12, main belt wheel cap 10 and main shaft 13, and main shaft 13 runs through motor gear wheel 11, driving pulley 12 and main belt wheel cap 10.Driving pulley 12 is placed on main belt wheel cap 10 and is installed in motor gear wheel 11, by the rotation for rotarily driving whole actuating unit of motor gear wheel 11.Gear wheel axle sleeve 14 and thrust bearing 15 are fixed with motor gear wheel 11, it act as making motor gear wheel 11 itself not directly by the frictional force produced because of rotation, and adds up-thrust bearing 15 then better.Power packages 1 are also further provided with unilateral bearing 16 and collar bush 17, and unilateral bearing 16 is placed in thrust bearing 15, and collar bush 17 is placed in unilateral bearing 16 and is placed on main shaft 13.Unilateral bearing 16 is fixed in motor gear wheel 11, then be fixed the direction of rotation of motor gear wheel 11, and aeromodelling airplane can be allowed slowly to decline when flight is unexpected, alleviates the infringement degree to aircraft parts.Main belt wheel cap 10 and driving pulley 12 are fixed on main shaft 13 on through collar bush 17 and with collar bush pin 18, and it is placed in motor gear wheel 11 and is coaxial therewith, and can reduce machine volume, effectively mitigates weight.
In the present embodiment, driving member is week restraining Timing Belt 2, specially polyurethane belt, and belt transmissioning mode is easily installed and is hardly damaged.
Empennage gear unit 3 includes synchronous pulley（It is not shown）And caudal wing shaft 31, synchronous pulley is fixed on caudal wing shaft 31 and drives the rotation of empennage steering mechanism.Empennage gear unit 3 is additionally provided with empennage belt foreign steamer 32 and empennage fixes lid 33, and empennage is fixed lid 33 and is made up of empennage fixed cover 330 and empennage fixation lower cover 331, and it is fixed on tail pipe.Empennage belt foreign steamer 32 is fixed lower cover 331 and is fixed together with synchronous pulley and caudal wing shaft 31 by empennage fixed cover 330 and empennage.The week restraining Timing Belt 2 is attached to synchronous pulley by empennage belt foreign steamer 32, then can protect week restraining Timing Belt 2, it is to avoid it produces shake, skidding.
