Abstract:
An anti-backlash mechanism, comprising:a support structure;a driven gear supported for rotation by the support structure;a driving gear, having an axis of rotation, engaging the driven gear;a resiliently biased support for the driving gear fast with the support structure along an edge, the edge of the support being parallel to the axis of rotation of the driving gear;an adjustment mechanism to adjust the resilient bias of the support and attached driving gear against the driven gear, to eliminate backlash therebetween, the driven gear is a worm wheel and the driving gear is a worm gear supported by bearing means fast with the support; andwherein the support is of an elongate shape where a length of the edge fixed to the support structure is greater than a distance between the edge fixed to the support structure, and an opposite edge supporting the bearing means and worm gear.
