Abstract (Inputs.Engineering)OptionalmoduleThe tooth size at the back, the gear's outer end: the outer pitch diameter divided by the teeth, in model units. Only gears of one module mesh.
OptionalteethHow many teeth the gear has, at least 3.
OptionalmateHow many teeth the gear it meshes with has. With shaftAngle it sets the cone the gear
rolls on.
OptionalshaftThe angle between the two gears' axes, in degrees; 90 turns a drive through a right angle.
OptionalpressureThe angle at which meshing teeth push on each other, in degrees; 20 is the common standard, and meshing gears share it.
OptionalbacklashHow much thinner each tooth is at the outer pitch circle than a tight fit, in model units.
OptionaladdendumHow far the teeth reach above the pitch cone at the back, as a share of the module.
OptionaldedendumHow deep the gaps reach below the pitch cone at the back, as a share of the module.
OptionalrootThe radius that rounds the bottom of each gap at the back, as a share of the module; it shrinks to fit a narrow gap.
The teeth of a straight bevel gear, shared by
engineering.mechanical.gears.bevelGearSizesandengineering.mechanical.gears.bevelGearOutline: their size at the back, the gear they mesh with and the angle between the two, their shape and how loosely they fit.
