Movement is also generated with driven member, the movement of driven member is consistent with the characteristics of motion that eccentric wheel generates.On driven member in extension hole location
Relative motion can also occur for the other parts of connection, although the characteristics of motion of other parts is about the movement desired by us,
But due to foozle and rigging error, the overall dimensions that not can guarantee after assembling every time are consistent, so the characteristics of motion one
Surely it can will not get a desired effect every time, just not achieved the desired results and showed by track on trolley.So just
Track is corrected through the invention, be equivalent to amendment driven member at a distance from eccentric wheel, rotate two pitch airscrew screw at this time, change
Relative displacement between driven member and reference block changes the distance between driven member and eccentric wheel.
Example calculates:
Former bolt spiral moving distance calculates:
L=NPh;
L: displacement when bolt rotates
N: rotating cycle
Ph: the lead of screw thread;
Ph=nP;
N: the number of leads
P: thread pitch
So:
If, using the screw thread of M3 × 0.5, screw pitch 0.5mm, line number 1 rotates 1 circle, bolt is mobile with plain screw
0.5mm, the fine tuning of trolley be it is very little, the displacement of 0.1mm can make the driving trace of trolley, and great changes will take place.

When=1:
Δ L=0.3mm,
I.e. when finely tuning the circle of two pitch airscrew screw 1, the distance of the mobile 0.3mm of bolt.
As shown in Figure 4, when two pitch airscrew screw rotates clockwise 1 circle, the moving displacement of driven member relative datum block is exactly
Driven member and master to connecting rod end advance 0.3mm, then for whole " s " word carbon-free trolley, in steering unit for front wheels
The Distance Shortened of moving axis causes Trolley front wheel to turn right certain angle, and trolley entirety track will turn right offset, to reach
Adjust the purpose of moving of car track to the right.
Similarly, when two pitch airscrew screw is rotated by 90 ° counterclockwise, the moving displacement of driven member relative datum block is exactly to connection
Bar end retreats 0.075mm, then driven member and driving shaft for whole " s " word carbon-free trolley, in steering unit for front wheels
Distance increase, cause Trolley front wheel to turn left certain angle, trolley entirety track will turn left offset, to reach adjustment
The purpose of moving of car track to the left.
