Equ Drvn Gear With "Diametrical Pitch", "Number of Teeth" & "Pressure Angle" as User Input

grabcad

An equation-driven involute spur gear tooth design in Solidworks features user input for Diametrical Pitch, Number of Teeth, and Pressure Angle. This template is stable but may break if inputs exceed its range; simply adjust values to fall within acceptable limits. The large gear example sets global variables including number of teeth (90), diametrical pitch (15), pressure angle (15), tip radius (0.025), and root radius (0.01). Users can also change addendum and dedendum values. Calculations include pitch diameter, outside diameter, and dedendum radius. Sketch dimensions are based on global variables. The parametric equation for the involute form is defined using Xt and Xy coordinates. A similar process applies to the small gear design with adjustable global variables like number of teeth (15), diametrical pitch (15), pressure angle (15), tip radius (0.005), root radius (0.03), root relief angle rad, and root relief angle. This small gear design includes additional dimensions and calculations specific to its features. Both large and small gears use equation-driven curves for involute formation, with defined t1 and t2 values. The small gear also incorporates global variables for root relief angle rad and root relief angle, ensuring proper clearance when mating with a larger gear. Adjust these values as needed to achieve desired results.
