ABSTRACT:
A gear system adapted to eliminate backlash between a set of reversible gears. The gears are also arranged to perform without backlash when their center distances are changed. One gear of the double helical type fixed to a first shaft is in engagement with a single adjustably secured first helical gear on a second shaft. A biased helical gear is slidably arranged on the second shaft adjacent the first helical gear, forcing the teeth of the biased gear against corresponding teeth of the double helical gear, automatically removing any clearance between them thus eliminating any backlash therewith, which is desirable for gears driving matched rolls.
