preloaded dual series pinions... to remove backlash | |
you can achieve a spit pinion by using 2 pinion one in series with each othere. Just like the link from altanta drives, but one will be your drive pinion
the other is setup to take out the backlash ....on the opposite leading edge of the rack tooth, Ie let say 2-3 inches behind your drive pinion.
Its the same concept just moved back afew teeth to best utilize the 1/2 track in a series fashion rathere than 2 pinions in parallal. The trick is the one pinion will be your drive pinion other will require adjustable slider to tune out the backlash... think of it as pinion mounted in a dovetail pocket slide with a adjustable screw. |
