Gear Basics: Backlash vs Lost Motion

Let's say that the top gear is driven by the motor, and the bottom gear is driving the load. To avoid the red part in the image above, the trick is to keep the top gear (and the motor) rotating clockwise (opposite of blue arrow). As long as the top gear and the bottom gear are always in contact, the red area is avoided, and backlash is eliminated. . However, this only works for unidirectional ...

Backlash (engineering) - Wikipedia

In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."

Spur Gears - Geometry of spur gears and gear meshes

Geometry of spur gears and spur gear pairs is reviewed. Methods and examples of geometric design are reviewed for spur gear pairs, given constraints on ratio, center distance, and clearances. For a given module and center distance, a gear pair is designed to achieve a desired gear ratio, while the gear geometry is constrained to certain criteria.
