Anti-backlash system and method of manufacture

A system comprising:

• a rotational driving device having a pinion;
• a load having a load gear configured to rotate in response to rotation of the pinion;
• an anti-backlash mechanism operably coupled between the rotational driving device and the load, the anti-backlash mechanism including:
• a frame;
• a first idler gear operably disposed between the pinion and the load gear;
• a first flexure device coupled between the first idler gear and the frame, the first flexure device applying a pre-load to the first idler gear to move the first idler gear into engagement with the pinion and the load gear;
• a second idler gear operably disposed between the pinion and the load gear;
• and
• a second flexure device coupled between the second idler gear and the frame, the second flexure device applying a pre-load to the second idler gear to move the second idler gear into engagement with the pinion and the load gear.

A method of assembling an anti-backlash assembly between a driving device and a load, the method comprising:

• coupling a first idler gear to a first flexure device, the first flexure device being disposed between the first idler gear and a frame;
• coupling a second idler gear to a second flexure device, the second flexure device being disposed between the second idler gear and the frame;
• pre-loading the first idler gear against a pinion with the first flexure device, the pinion being coupled to the driving device;
• and
• pre-loading the second idler gear against the pinion with the second flexure device.
