Description
Technical field
The application is related to driving engine technical field, specifically, is related to a kind of face gear train assembly.
Background technology
Engine (Engine) be it is a kind of can be the machine that can be converted into mechanical energy of other forms, including such as internal combustion engine
(petrol engine etc.), external-combustion engine (Stirling engine, steam engine etc.), motor etc..As internal combustion engine is typically a chemical energy
It is converted into mechanical energy.Engine is not only suitable for power generating apparatus, can also refer to the whole machine including power set (such as：Gasoline
Engine, aero-engine).Engine is born in Britain earliest, so, the concept of engine also comes from English, its literal sense
Refer to " mechanical device for producing power ".
Aero-engine is the thermal machine of a kind of high complexity and precision, the hair of power for needed for airborne vehicle provides flight
Motivation.As the heart of aircraft, " flower of industry " is described as, it directly affects performance, reliability and the economy of aircraft, is one
The important embodiment of individual national science and technology, industry and military capability of the country.At present, High Performance Aeroengine can be independently developed in the world
Country only has a few countries such as the U.S., Russia, Britain, France, and technical threshold is very high.
Aero-engine has 3 types：
Piston aviation engine, is the aero-engine applied on aircraft or helicopter in early days, for driving spiral
Oar or rotor.The power of Large-scale Reciprocating aero-engine is up to 2500 kilowatts.Later is the combustion gas that power is big, high speed performance is good
Turbogenerator is replaced.But low power piston aviation engine is still widely used for light aerocraft, helicopter and ultralight
Type aircraft.
Gas-turbine unit, this engine application is most wide.Including turbojet, turbofan,
Turboprop and turboaxle motor, all with compressor, combustion chamber and gas turbine.Turboprop
It is mainly used in aircraft of the speed per hour less than 800 kms；Turboaxle motor is mainly used as the power of helicopter；Turbofan
It is mainly used in speed aircraft higher；Turbojet is mainly used in supersonic plane.
Punching engine, is characterized in without compressor and gas turbine, when the air into combustion chamber utilizes high-speed flight
Punching press effect supercharging.Its simple structure, thrust are big, are particularly well-suited to high speed high-altitude flight.Due to being unable to self start and low
The lower poor performance of speed, limits range of application, is used only on guided missile and air-launched target missile.
Above-mentioned engine by draw air in air as fuel combustion oxidant, therefore also known as air breathing engine.
Other also have rocket engine, pulsed motor and aeroplane motor.The propellant (oxidant and incendiary agent) of rocket engine
All by self-contained, fuel consumption is too big, is unsuitable for working long hours, generally as the engine of carrier rocket, in aircraft
On be only used for the short time accelerate (such as starting accelerator).Pulsed motor is mainly used in low speed target drone and aerial model airplane.By
The aeroplane motor that solar cell drives is only used for light aerocraft, is still in experimental stage.
Aircraft engine accessory is driven casing abbreviation accessory drive gearbox, is typically extracted from engine rotor axle by bevel-gear sett
Power, then transmits power to each engine accessory power rating and aircraft accessory by another bevel-gear sett.
During Bevel Gear Transmission, the vertex of a cone of two bevel gears will overlap, if producing axial error, it will produce serious
Unbalance loading phenomenon.Therefore, in some important Bevel Gear Transmissions, anti-dislocation (preventing the vertex of a cone from separating) design is exclusively carried out；Cone
Gear is many in manufacturing process to be manufactured using pairing, i.e., in the fabrication process, little gear is processed first, then basis
The Gear shape process of little gear goes out the matched gear wheel for using, and because little gear is easier abrasion, fails faster, therefore more
Can only be while changing bevel-gear sett when changing.
The tooth surface shape of bevel gear (particularly spiral bevel gear) is more complicated, in the fabrication process, the shape of the flank of tooth
Disunity, therefore different by the usual tooth surface shape of bevel gear of different manufacturer productions, parameter it is also different (such as Gleason system,
Ao Likang bevel gears etc.), this causes very burden for processing and manufacturing, detection and the maintenance of bevel gear.
To sum up, the bevel gear for being applied to accessory drive gearbox on the market at present has as a drawback that：
1st, bevel gear easily misplaces and causes unbalance loading, is also easy to produce error；
2nd, the easy wear out failure of little gear, it is durable bad；
Can only in pairs be processed when the 3rd, processing, process, detect and maintenance requirement is high, specification disunity.

3 transmit to accessory drive gearbox the power of power source, then preach to other annexes.First, the application is by by face pinion unit
System substituted for the transmission system of bevel gear, and the face gear train assembly of the advantage is that is the phase with roller gear 2 by face gear
Mutually engagement does not almost have to transmission performance realizing transmission, typically straight spur gear, thus error that its axial movement is produced
Have an impact, as face gear mesh installs insensitive along tooth alignment error, reduces installation difficulty；Second, small tooth in the gear drive of face
Wheel standard Involute spur gear causes that repair and replacement are easier, it is not necessary to which special anti-dislocation apparatus are so as to mitigate system weight
Amount；3rd, bevel gear is differed due to shape, and due to needing precisely occlusion, so needs are processed into pairs, and is needed during maintenance
To change in pairs, and for bevel gear, face gear and roller gear 2 can be individually replaced, individually maintenance, individually protect
Support, dismounting is simple, easy to maintenance；4th, bevel gear shape matching is complicated, shape also disunity, different manufacturers production during manufacture
Product be typically due to that shape is different, parameter differs and leads to not accurately be engaged, for processing and manufacturing, detection and tie up
Repair and cause huge trouble, and face gear is processed according to the true meshing relation of face gear and roller gear space.Cause
This, face gear and roller gear all have the unified theoretical flank of tooth so that processing detection possesses unified standard.
Further, first face gear 1 includes the first gear axle 11 being connected with the power source and sets
Being placed on the first gear axle 11 is used for and the intermeshing first gear disk 12 of the input end gear 21.

It is to be appreciated that roller gear 2 has following mechanical feature：It is long along its tooth during the gear mechanism engaged transmission
There is larger circumferentially opposite sliding speed in direction, thus can produce larger abrasion；On the other hand, two tooth profiles are in point and connect
Touch state, its contact stress value can very big cause q faces too early by pressure present, promote wheel odontotripsis aggravate.With parallel axes helical gear phase
Than the service life and mechanical efficiency of crossed helical gears mechanism are all much lower.
It is to be appreciated that the application scenario of roller gear 2：Due to alternating axis helical gears, mechanism has above-mentioned spy
Point, therefore the mechanism should not be used in transmission power, that is, should not be used in the environment at a high speed with heavier load, typically be only suitable for for passing
Pass motion or be used to change the direction of motion.The helical angle size and Orientation of two gears of crossed helical gears mechanism is all not necessarily
It is identical, thus the relative steering of olive centre-to-centre spacing, angular velocity ratio and two-wheeled can be adjusted by changing helical angle A. and intestines.This is allowed for
The gear mechanism has larger flexibility in transmission geometrical relationship, it is easy to which the motion transmission for meeting any staggeredly between centers will
Ask.
