Abstract
The utility model provides a group of components of power transmission for aeromodelling, comprising a power group, an empennage transmission unit and a transmission part. The transmission part is synchronized belt of cycle holding. The empennage transmission unit and the power group are respectively arranged at both ends of the synchronized belt. The transmission part of the utility model adopts the mode of synchronized belt driving empennage and overcomes shortcomings of easy wear, difficulty in maintenance and high technical requirements for fitting. In the meanwhile, the drive pulley sleeved onto the large gear of the motor reduces the volume and weight of the whole machine. In addition, a one-way bearing is arranged in the large motor gear, which enables the helicopter to tardily power off and land under exceptional situation. Thereby, damage on helicopter is reduced.
Description
Technical field
The utility model relates to the model plane field, refers to a kind of power driving module of model plane especially.
Background technology
Driving member in the general model plane power driving module is through-drive, not wear-resisting being easy to of through-drive mode damaged, not easy-maintaining and assembly technical requirement height, power gear group volume is bigger and heavy, and bearing rotates then big to the aircraft damage degree round about when going straight up to the opportunity fortuitous event.
Summary of the invention
Based on the deficiencies in the prior art, it is a kind of wear-resistant that main purpose of the present utility model is to provide, and the assembling maintenance is easy to the power driving module of model plane.
In order to achieve the above object, the utility model provides a kind of power driving module of model plane, comprise power packages, empennage gear unit and driving member, described driving member is a week restraining band synchronously, and empennage gear unit and power packages place week restraining band two ends synchronously respectively.
Described power packages comprises motor gear wheel, driving pulley and main shaft, and described main shaft runs through motor gear wheel and driving pulley, and driving pulley places in the motor gear wheel.
Described power packages further comprises gear wheel axle sleeve and thrust bearing, and described gear wheel axle sleeve is fixed in the motor gear wheel, and described thrust bearing places in the gear wheel axle sleeve.
Described power packages also further is provided with unilateral bearing and collar bush, and unilateral bearing places thrust bearing, and collar bush places unilateral bearing, and described main shaft runs through collar bush, unilateral bearing, thrust bearing and gear wheel axle sleeve.
Described power packages also further comprises the driving pulley lid, and driving pulley places driving pulley to cover.Described driving pulley lid and driving pulley run through collar bush and are fixed on the main shaft.
Power driving module also further comprises pre-bearing up pulley, and it is fixed on the mainboard frame by pre-bearing up pulley fixed mount.
Described empennage gear unit comprises synchronous pulley and caudal wing shaft, and described synchronous pulley is fixed on the caudal wing shaft.
Described empennage gear unit also further comprises empennage belt foreign steamer and empennage fixed cap, and empennage belt foreign steamer is fixed together by empennage fixed cap and synchronous pulley and caudal wing shaft.
Described week restraining is with an end to be placed in driving pulley synchronously, and its other end is placed in synchronous pulley.
Compared with prior art, driving member of the present utility model adopt the week restraining synchronously band drive the kind of drive of empennage, remedied that through-drive damages easily, not easy-maintaining, drawback that assembly technical requirement is high.And driving pulley is placed in the new mode in the motor gear wheel, has dwindled the volume of complete machine, has alleviated weight.And unilateral bearing is arranged in the motor gear wheel, and helicopter can slowly be put out because of fortuitous event, reduced the damage of aircraft.
For making the utility model easier to understand, further set forth the specific embodiment of the power driving module of a kind of model plane of the utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of the power driving module of the utility model model plane.
Fig. 2 is the decomposition texture schematic diagram of the power driving module power packages of the utility model model plane.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The utility model power driving module 100 is installed in the fuselage main body and urosome of model plane, constitutes the power spare of model plane.It comprises power packages 1, empennage gear unit 3 and driving member, and empennage gear unit 3 and power packages 1 are installed on the driving member two ends respectively.Drive the work of empennage gear unit 3 by power packages 1.
In the present embodiment, driving member is with 2 synchronously for the week restraining, is specially the polyurethane belt, and belt transmissioning mode is easy to install and is not fragile.
Empennage gear unit 3 comprises synchronous pulley (figure does not show) and caudal wing shaft 31, and synchronous pulley is fixed on the caudal wing shaft 31 and drives the rotation of empennage steering mechanism.Empennage gear unit 3 also is provided with empennage belt foreign steamer 32 and empennage fixed cap 33, empennage fixed cap 33 by empennage fixed cover 330 and empennage fixedly lower cover 331 constitute, it is fixed on the tail pipe.Empennage belt foreign steamer 32 by empennage fixed cover 330 and empennage fixedly lower cover 331 be fixed together with synchronous pulley and caudal wing shaft 31.Described week restraining is with 2 to be attached to synchronous pulley by empennage belt foreign steamer 32 synchronously, then can protect the week restraining to be with 2 synchronously, avoids it to produce shake, skidding.
The utility model power driving module comprises that also two pre-bearings up pulley 41,42 and pre-bearing up pulley fixed mount 43, two pre-bearings up pulley 41,42 are fixed on the mainboard frame by pre-bearing up pulley fixed mount 43.Described week restraining is placed in the driving pulley 12 of power packages 1 synchronously with 2 one ends, it passes the synchronous pulley that 41,42 other ends of two pre-bearings up pulley are placed in empennage gear unit 3, then can avoid rotating the shake that produces, sliding zoning at a high speed because of belt.
