Abstract
The present invention realizes a kind of pneumatic starter of internal combustion engine, which is suitable for the starting of all kinds of internal combustion engines with air pump and air accumulator.When pressing shut-off valve 6, the shell that pilot gas initially enters pneumatic primer 7 pushes meshing gear to stretch out and engages with internal combustion engine flywheel gear ring, the gas control two-position three-way valve 5 of pneumatic primer reflux gas driving simultaneously is turned on, gas in this way in air accumulator 2 is connected by the air inlet of check valve 4 and pneumatic primer 7, and then pushes turbine rotation.After engine starting, shut-off valve 6 is closed, without pilot gas in 7 shell of gas powered internal combustion engine, meshing gear can be detached from flywheel ring gear under the action of the spring.Simultaneously because not controlling gas, such gas control two-position three-way valve 5 can be closed, and pneumatic primer 7 stops operating.This pneumatic primer is small in size, light-weight, safe and reliable, can exchange with electric starter in structure, be particularly suitable for the special car that coal mine etc. has requirement of explosion proof.
Description
Technical field
The present invention realizes a kind of internal combustion engine Pneumatic starting system.It can be vehicle, engineering machinery, generating set, ship
Equal internal combustion engines, which provide, starts solution, belongs to field of power machinery.
Background technique
The starting overwhelming majority of internal combustion engine uses electrically actuated mode at present.Due to this mode it is simple and convenient and by
Most of internal combustion engine is used.However in some special occasions, for example underground work such as coal mine have particular requirement to explosion-proof
The special car of occasion, the mode of this electrically actuated internal combustion engine in starting process due to will appear electric spark, to there is peace
Full hidden danger.In order to solve this hidden danger, the present invention devises a kind of internal combustion engine Pneumatic starting system, does not have in the system work process
There is any electric element, therefore is capable of the requirement of explosion proof of special vehicle.
In order to be replaced with the electric activation system of current internal combustion engine, designed pneumatic primer is in interface section
It is consistent with original motor driven starter, exchange it can with motor driven starter in structure, reduced to vehicle change
It is required that.
Summary of the invention
A kind of internal combustion engine Pneumatic starting system is by gas source 1, air accumulator 2, safety valve 3, check valve 4, gas control two-position three-way valve
5, shut-off valve 6 and pneumatic primer 7 form.Its starting that can be realized traditional combustion engine.
When starting, opens 6 gas of shut-off valve and initially enter the meshing gear housing hollow of pneumatic primer 7 and push cunning
Block, and then meshing gear stretching is pushed to engage with internal combustion engine flywheel gear ring.After sliding block is mobile, gas can be flowed back by one
Hole driving gas control two-position three-way valve 5 makes air accumulator 2 and starts the inlet communication of engine 7, and the gas in such air accumulator 2 enters
The turbine inlet of pneumatic primer 7 pushes turbine rotation, and the rotation of turbine drives the center sun gear of planetary reducer
Rotation.
The pilot gas of reflux, reflux will enter one end of relay valve, and push the sealing block inside relay valve, and then beat
Relay valve is opened, working gas is allowed to enter turbine inlet, pushes turbine rotation.The retainer of planetary reducer is the defeated of it
Outlet, and retainer and transmission shaft are linked together by spline.Therefore the rotation of turbine is defeated by transmission shaft after slowing down
Out.Also coupled with spline between transmission shaft and slidable meshing gear, such transmission shaft just drives meshing gear to drive internal combustion
The rotation of machine flywheel ring gear, realizes the starting of internal combustion engine.
After the completion of engine starting, disconnect shut-off valve 6, stop into the meshing gear housing hollow of pneumatic primer 7 into
Enter gas.The guide of gas control two-position three-way valve 5 drives gas to be cut off.In this way under the action of reset spring, gas control two three
Port valve 5 will reset rapidly within the several seconds, and then cut off air accumulator 2 and connect with 7 mouthfuls of pneumatic primer of gas, pneumatic to rise
Motivation 7 will also stop working, and so far complete entire starting process.

Specific embodiment
Below with reference to examples illustrate the present invention.
As shown in Figure 1, internal combustion engine Pneumatic starting system chief component has 1 gas source, 2 air accumulators, 3 safety valves, 4 unidirectionally
Valve, 5 gas control two-position three-way valves, 6 shut-off valves, 7 pneumatic primers.
Overwhelming majority heavy vehicle institute matched inflating pump when gas source 1 mentioned here.The gas obtained of gas source 1 in this way
It is stored in air accumulator 2, pressure need to be used in order to guarantee that the pressure in air accumulator 2 is unlikely to be higher than, be mounted on air accumulator 2
Full valve 3.When internal combustion engine needs to start, shut-off valve 6 is opened, gas enters guide's air inlet on 8 shell of meshing gear.
Guide's air inlet will push sliding block 9 to move right (see figure 2) after entering gas.After sliding block 9 moves right a distance, gas
Enter the control terminal of gas control two-position three-way valve 5 by another mouthful on 8 shell of meshing gear, and then makes air accumulator 2 and gas
The turbine air-intake of mechanical starter 7 connects, so that gas push turbine rotor blade wheel 14 rotates.
Turbine mainly includes turbine shroud, stationary blade wheel 13, movable vane wheel 14, turbine wheel shaft 12.Stationary blade wheel 13 is for generating air inlet
Leaf grating.Turbine wheel shaft 12 is assembled together with the interference fit of movable vane wheel 14.When working gas pushes movable vane wheel 14 to rotate, also drive
Turbine wheel shaft rotation.When admission pressure is 8bar, 50,000 turns per minute of the rated speed of turbine.
For the matching of revolving speed and engine starting revolving speed, the output end of turbine wheel shaft 12 is the center of planetary reducer
Sun gear.The shell inner headed face of planetary reducer is processed into internal gear, the big sun gear as planetary reducer.Row
Star gear reduction unit in addition there are three or four planetary gears.When turbine wheel shaft rotates, the row of planetary reducer will be driven
Star retainer rotates together and realizes deceleration.By planetary reducer, the rated speed of transmission shaft is 4500 turns per minute.
