First Claim
Patent Images
1. A gear transmission for minimizing backlash, the gear transmission comprising:
- a first shaft;
a first roller slidably positioned on the first shaft;
a first gear positioned on the first shaft;
a second shaft;
a second roller positioned on the second shaft and adjacent the first roller; and
, a second gear positioned on the second shaft and adjacent the first gear;
wherein the first roller and the second roller abut when teeth of the first gear mesh with teeth of the second gear.

Abstract
The gear mechanism for minimizing backlash may include a convoluted spring positioned between an external spline of a gear or shaft and an internal spline of a gear. The gear mechanism may include a cam and cam follower arrangement upon two adjacent gears positioned on the same shaft. Two stacked gears may include a U-shaped backlash eliminating element passing through both gears. The gear mechanism may include rollers which may be conically shaped.
