Although elemental gear inspection is rarely specified formolded plastic gears, themeasurement equipment and practices can bevaluable in advancing the molding processes and improving thequality of the molded gears. After a brief description of plasticgear tooling and molding, this paper gives examples of specificelemental measurements and relates themto process changesandquality improvements.Such examples for spur and helical gearsinclude: profile measurements leading to gear mesh noise reduction;lead measurement leading to increased face width load distributionand, continuing from that, even to the molding of crowned gears;and index measurement leading to improved roundness of gears moldedfrom fiber reinforced plastic materials.
