The larger board area and wider pitch line accommodate the increased volume needed for components and to provide more power to the board.
Pitch diameter size/minimum material pitch diameter: This single feature check is best done with the three-wire method or thread comparator whose gaging rolls are made to contact at the product pitch line only.
Since shot peening introduces a compressive stress that prevents crack propagation or movement, it can also be used to prevent pitting problems at a gear pitch line.
Gearset backlash can be thought of as the maximum amount of movement of the gear at its pitch line with the worm fixed and the gearset on exact center distance.
Due to the high pitch line velocities of up to 200 m/s, oil swirling and oil squeezing in the gear mesh account for a substantial part of the power loss of high-speed turbo gear units.
