Row lubrication, to realize the lubrication to pneumatic vibrator mechanism entirety.
As shown in Fig. 4 to Figure 12, the self-lubricating process for carrying the pneumatic vibrator mechanism of lubrication is as follows:
As shown in figure 4, compressed air enters from P mouthfuls of 1 rear end cap of serial number, and entered along the A stomata on 2 distribution block of serial number
" Q1 " pushes 4 piston rod of serial number to move forward, at this point, air cavity " Q2 ", air cavity " Q3 " and gas vent " O " communicate, meanwhile, serial number 4
The gas passage " B " for being passed through air cavity " Q2 " is closed in the rear end of piston rod.
As shown in figure 5, compressed air continues to enter " Q1 " air cavity along " A " air flue, 4 piston rod of serial number is pushed to continue to move forward
It hits, the air flue " B " for being passed through air cavity " Q2 " is still closed, but at this point, 4 piston rod of serial number begins to shut off gas vent " O " and gas " Q3 ".
As shown in fig. 6, the rear end of serial number 4 " piston rod " is closed as serial number 4 " piston rod " continues ballistic motion forward
" A " air flue enters air cavity " Q1 ", and " B " air flue is still closed, the expansion of the compressed air of air cavity " Q1 ", push 4 piston rod of serial number after
Continuous to impact forward, since air cavity " Q2 " is airtight cavity, with the impact forward of 4 piston rod of serial number, cavity space is become by compression
Small, gas pressure is gradually increased.
As shown in fig. 7, the compressed air of air cavity " Q1 " continues to expand, 4 piston rod of serial number is pushed to continue ballistic motion forward,
At this point, " B " air flue is opened in the rear end of 4 stopper rod of serial number, compressed air initially enters " Q2 " air cavity, at this point, into " Q1 " air cavity
Air flue be still within closed state." Q1 " air cavity will be connected with gas vent " O ", into exhaust condition, 4 piston rod of serial number
Front end will impact the rear end face of vibrating rod.
As shown in figure 8,4 piston rod of serial number impacts vibrating rod rear end face, at this point, due to air cavity " Q1 " and gas vent " O "
It connects, air flue " A " is in close state, and therefore, the pressure of air cavity " Q1 " is zero, and the pressure of air cavity " Q2 " has been raised to
0.5Mpa, therefore, 4 piston rod of serial number start ballistic motion backward, and air flue " B " is opened, and compressed air enters air cavity " Q2 ", air flue
" A " is still within closed state.
As shown in figure 9, the ballistic motion backward of 4 piston rod of serial number, and air flue " B " is closed, while air cavity " Q1 " and gas vent
" O " is closed, and air flue " A " is still within closed state, and air cavity " Q1 " becomes airtight cavity, and gas starts compressed in cavity,
Cavity pressure is gradually increasing, and the compressed air expansion in air cavity " Q2 " pushes the continuation of 4 piston rod of serial number to do ballistic motion backward.
As shown in Figure 10, air cavity " Q2 " gas continues to expand, and 4 piston rod of serial number is pushed to continue ballistic motion backward, air flue
" B " is still within closed state, and the gas of air cavity " Q1 " is still within confined state, at this point, the rear end of 4 piston rod of serial number
It will open air flue " A ", compressed air will enter air cavity " Q1 ".
As shown in figure 11,4 piston rod of serial number continuation moves backward, and air flue " A " is in the open state, and compressed air enters gas
Chamber " Q1 " is exhausted, air flue " B " is still within closing at this point, air cavity " Q2 " will be connected with air cavity " Q3 ", gas vent " O "
State, the gas surplus pressure of air cavity " Q2 " is in 0.5 MPa or so at this time.
As shown in figure 12, at this point, air flue " A " is opened, compressed air enters air cavity " Q1 ", pushes 4 piston rod of serial number forward
Ballistic motion is done, the compressed gas of air cavity " Q2 " is discharged by gas vent " O " and " Q3 ", and pressure is reduced to zero, wherein is discharged into gas
The compressed gas of chamber " Q3 " passes through the air flue on 9 spline gear section of serial number " C ", into air flue " F " and " D ", to 7 front and back of serial number
Bearing provides lubrication, into air flue " E ", provides lubrication to gear field of conjugate, and these oil gas with pressure enter gear-box
Body provides lubrication for the intracorporal gear of case and bearing, finally, being discharged along oil discharge outlet.
