Abstract
A mechanism for de-lashing a gear assembly includes a first gear rotatable about a first axis and a first center rotatably fixed to the first axis and a first conical teeth portion. The gear assembly includes a second gear rotatable about a second axis and a second center rotatably fixed to said second axis and a second conical teeth portion configured to meshingly engage first conical teeth portion when the first and second gears are aligned substantially coplanarly. A biasing means operably biases the second conical teeth portion of the second gear against the first conical teeth portion of the first gear to reduce any lash therebetween. The biasing means is configured to bias the second gear in an axial direction while maintaining a fixed center distance between the first and second axes. The first gear is rotatably fixed about the fixed first axis such that the first gear is prevented from translation along the fixed first axis.
