Abstract
The utility model provides a model airplane dynamic assembly that consists of a main dynamic assembly, an ancillary dynamic assembly and a tail drive axle. The tail drive axle connects the main dynamic assembly and the ancillary assembly. The main dynamic assembly comprises a main axis, a gear cluster and a fixing sleeve. The gear cluster comprises a big motor gear concentrically coated on the main axis and a big steering gear. The big motor gear is provided with a round groove in the middle and the big steering gear is arranged in the groove. The two ends of the tail drive axle are respectively provided with a drive pinion. The gear cluster structure greatly simplifies the overall structure of the model airplane, lightens weight of the airplane, efficiently reduces energy consumption and prolongs flight time. Besides, a single-direction bearing is arranged to force that the main wings of the model airplane can rotate in only one direction and the flight control method realizes that the model airplane falls slowly when flight accidents happen to protect the airplane body and minimize the crash loss.
Description
Technical field
The utility model relates to the model plane field, refers to a kind of Power Component of model plane especially.
Background technology
But general aeromodelling airplane drives the rotation of whole steering mechanism by belt transmission or gear drive, because the long-term friction of belt is used causes than galling, makes that whole steering mechanism is insensitive in the belt transmission; And gear-driven Power Component is made up of several gears, wherein, two master gears of equal diameters are parallel to be run through main shaft superimposedly and rotates synchronously with axle, one of them master gear drives with the propeller unit that is installed on the main shaft and rotates synchronously, and the gear of tail transmission shaft end is meshed with the another one master gear, drives the empennage steering unit by gear wheel and rotates synchronously with axle, like this, make airframe structure comparatively complicated, and increased the overall weight of fuselage, the weight increase will increase energy consumption.
In view of this, need provide a kind of Power Component that can simplify the aeromodelling airplane of airframe structure.
Summary of the invention
Based on the deficiencies in the prior art, main purpose of the present utility model is to provide a kind of Power Component that can satisfy the model plane of long-time flight.
In order to achieve the above object, the utility model provides a kind of Power Component of model plane, comprise the active force assembly, from Power Component and tail transmission shaft, by tail transmission shaft connection active force assembly with from Power Component, the active force assembly comprises main shaft, gear train and fixed cover, gear train comprises the motor gear wheel of concentric locking collar on main shaft and turns to gear wheel, motor gear wheel middle part offers circular groove, turn to gear wheel to be built in this groove, the motor gear wheel is installed on the main shaft by the gear wheel axle sleeve that runs through main shaft, and drive pinion is equipped with at the both ends of tail transmission shaft respectively.
Wherein, comprise caudal wing shaft and cover empennage tooth sector and empennage turning sleeve thereon from Power Component.The drive pinion of tail transmission shaft end respectively with the turning to gear wheel and be meshed of active force assembly from the empennage tooth sector of Power Component.
Power Component further comprises the unilateral bearing that is embedded in the gear wheel axle sleeve.Turn to the flank of tooth of gear wheel vertical with main shaft.
Further be with the tailing axle fixture on the caudal wing shaft, the empennage tooth sector located by the tailing axle fixture.Tail transmission shaft also is with tail pipe outward.Main shaft also is with collar bush outward, and described unilateral bearing closely is set on the collar bush.
Compared with prior art, in the utility model, unilateral bearing, turn to gear wheel and Large Gear Shaft During cover to connect to be fixed as one, it is looked as the single motor gear wheel, the fixed form of this gear combination structure is outward appearance novelty, uniqueness not only, and has simplified the overall structure of aeromodelling airplane greatly, has also alleviated the weight of fuselage, effectively reduce energy consumption, prolonged the flight time.In addition; settle unilateral bearing; be another feature of the present utility model; it forces aeromodelling airplane to rotate towards a direction; this flight control method makes model helicopter motor when running into inflight emergency can not quit work because of opposing screw reverse resistance exhausts electric power at once; make aeromodelling airplane slowly to descend, air crash loss is dropped to minimum, fuselage is played a protective role.
For making the utility model easier to understand, further set forth the specific embodiment of the Power Component of a kind of model plane of the utility model below in conjunction with accompanying drawing.
