Description
Technical field
The utility model belongs to model plane design field, and in particular to a kind of easy engine model electric starter.
Background technology
At present, engine model mostly dials paddle startup using hand, external starter starts, pulls the modes such as line startup starts,
Unexpected rotate of engine easily makes operator be injured by paddle, and security risk is bigger.On the motorcycle that some scholars use for reference
Centrifugal or lever motor poor universality, weight is big, volume is big, impracticable for model plane.
The content of the invention
The purpose of this utility model is that solving the problems, such as that the starter of current engine model exists, a kind of letter is provided
Easy engine model electric starter.
The technical solution adopted in the utility model is：A kind of easy engine model electric starter, by startup motor
Seat starts motor retainer, starts motor, unilateral bearing, pinion gear, gear wheel and axle sleeve composition.The startup motor leans on
Start motor cabinet to be fixed on engine crankcase, and strengthen fixing by startup motor retainer；The unilateral bearing is mounted on
On the motor shaft for starting motor, Internal and external cycle combines after electrical power is started and drives pinion rotation；It is described with it is unidirectional
The bull gear drive that the pinion gear drive of bearing outer ring engagement is engaged with, gear wheel are started by axle sleeve drive connected therewith
Machine crankshaft rotates；The quality of the gear wheel concentrates on outside when being moved in lightening hole, gear wheel during normal working of engine
Wheel action can be played；After engine normally starts, start motor power-off, engine is still with bull gear drive, gear wheel at this time
With pinion rotation, unilateral bearing outer ring surmounts inner ring, and so as to which Internal and external cycle separates, motor, which will not be dragged, to be turned.
The startup motor is fixed on by starting motor cabinet on engine crankcase, and is strengthened admittedly by startup motor retainer
Fixed, complete machine oscillation is small.
The unilateral bearing is mounted on the motor shaft for starting motor, and outer ring is interference fitted with pinion gear endoporus.
The quality of the gear wheel concentrates on outside when being moved in lightening hole, and gear wheel can rise during normal working of engine
Wheel action.
After the startup electrical power, motor shaft drives unilateral bearing inner ring to rotate, and Internal and external cycle, which combines, drives pinion gear
It rotates, the bull gear drive that pinion gear drive is engaged with, gear wheel drives engine crankshaft to turn by axle sleeve connected therewith
It is dynamic；After engine normally starts, start motor power-off, engine is still with bull gear drive at this time, and gear wheel is with pinion gear
It rotates, unilateral bearing outer ring surmounts inner ring, and so as to which Internal and external cycle separates, motor, which will not be dragged, to be turned.
Compared with the prior art, the beneficial effects of the invention are as follows：
（1）Remote control starts, relatively safety；
（2）Electric starter is strengthened fixing, with small vibration；
（3）It is simple in structure, it is light-weight；
（4）Gear wheel can make flywheel in engine normal operation.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
A kind of easy engine model electric starter disclosed in the utility model by startup motor cabinet 2, starts motor
Retainer 3, startup motor 4, unilateral bearing 5, pinion gear 6, gear wheel 7 and axle sleeve 8 are formed.
The startup motor 4 is connected to the engine by motor cabinet 1, and the motor spline 3 and duplex-gear on motor 2 are big
Increment 71 engages.
The duplex-gear 7 is bolted in duplex tooth shaft 5, has duplex-gear between duplex-gear 7 and duplex tooth shaft 5
Bearing shell 6, duplex-gear bearing shell 6 and duplex tooth shaft 5 form revolute pair, ensure that duplex-gear 7 can be around 5 smooth rotation of duplex tooth shaft.Duplex
Tooth shaft 5 is slightly above duplex-gear bearing shell 6, to ensure the normal rotation of duplicate gear 7.
The duplex-gear small end 72 is engaged with gear wheel 8, and gear wheel 8 is connected by screw on one-way shaft bearing sleeve 9, single
It is fixed on to bearing holder (housing, cover) 9 by a pair of of semi-circular carbon plate 13 on engine bearer, to ensure to be axially moveable.
The unilateral bearing 10 is mounted on the inside of one-way shaft bearing sleeve 9, the needle roller of unilateral bearing 10 and after being sleeved on engine
The outer surface contact of axle sleeve 11 on output shaft, the inner surface of axle sleeve 11 is 1:20 conical surface, outer surface is cylindrical surface, and is passed through
Key and engine spindle（Bent axle）Connection.
When moving the starting switch on remote controler, motor 2 drives duplex-gear rotation 7, and duplicate gear 7 drives unilateral bearing
10 outer rings turn, and the needle roller of single line bearing 10 compresses axle sleeve 11 at this time, drives engine spindle（Bent axle）It rotates together；When starting
After machine starts, startup power supply is cut off, far more than the rotating speed of gear wheel 8, unilateral bearing needle roller falls into for the rotating speed of engine spindle 12
Ramp bottom, axle sleeve are no longer compressed by it, so gear wheel will not be rotated with engine spindle.
Above example is only to illustrate the technological thought of the utility model, it is impossible to the protection model of the utility model is limited with this
Enclose, every foundation the utility model proposes technological thought, any change done each fallen within the scope of the present invention.
