Abstract (Inputs.OCCT)OptionalmoduleThe module of the gears the rack meshes with, in model units.
OptionalteethHow many teeth the rack has, at least 1.
OptionalpressureThe angle of each flank from square to the pitch line, in degrees; it matches the gears'.
OptionalbacklashHow much thinner each tooth is at the pitch line than a tight fit, in model units.
OptionaladdendumHow far the teeth reach above the pitch line, as a share of the module.
OptionaldedendumHow deep the gaps reach below the pitch line, as a share of the module.
OptionalrootThe radius that rounds the bottom of each gap, as a share of the module; it shrinks to fit.
OptionalheightHow far the back of the rack lies below the pitch line, in model units, beyond the gaps.
OptionalframeThe frame the rack lies in: the first tooth's middle at the origin, the rack along the direction, its face toward the normal. Left out, the ground, facing +Y.
The teeth of an involute rack, shared by
parts.mechanical.gears.rackProfileandparts.mechanical.gears.rack: their size and shape, how loosely they fit, how deep the rack is and where it lies.
