Gear design and backlash are also beyond the scope of this standard. Type B1 Single split clamp hub with H7 bore and keyway. Backlash : Backlash is the amount by which the sum of the circular tooth thickness of two gears in mesh is less than the circular pitch. backlash is a concern, multiple nuts or nuts that are slit can be preloaded with spring elements to reduce backlash and provide the local compliance needed. • Crowned and barrelled teeth for optimum contact and long life. A best practice in gear design is to limit the amount of backlash to a minimum value needed to accommodate manufacturing tolerances, misalignments, and deflections, in order to prevent the non-driving side of the teeth to make contact and rattle. 5 DP) are now included.
