Rack: Toggle this to get a single tooth that can be extended to a rack by an array modifier.Ĭrown: A nonzero value creates a crownwheel (a gear with teeth that point downward)Īll other parameters should be considered experimental and may not to workįrom math import cos, sin, tan, atan, asin, pi, radians as radįaces=,]Įfc = zip(ef,ef2,ef2,ef) 45 degrees can be used for perpendicular axes. This angle determines the skew.Ĭonical angle: Conical gears can be used to link non parallel axes. Helical angle: Teeth don't have to be perpendicular to the face of the gear. Pressure angle: The slope of the tip of the teeth Ī negative radius creates an inverted gear (a gear with teeth on the inside).Īddendum: The amount the tip of a tooth extends above the radiusĭedendum: The amount the through between two teeth extends below the radiusīase: The thickness of the rim of the gear Gears that interact should be tangent (= touching each other) on their radii. Less than 5 is treated special: this will create a wormwheel. Teeth: the number of teeth, equally spaced along the radius of the gearInspired by the work of Stefano Selleri ().Ĭheck for a tutorial and additional info. Just send me a private message here at and we can work out the details. If you really need help still, I can make the gears for you. If you use 2.5, you can go to the user preferences, then go to the addons tab, then enable gears addon. Below is the gears script that works for 2.49.
