SMSR Gearbox Designing – Industrial Approach in English

Decide gear ratio and gear reduction for a multi-stage gearbox by selecting gear teeth Z1 through Z4, using pitch circle diameter and module, and multiplying stage ratios.

Discover how to determine the maximum gear ratio and reduction in a gearbox housing by analyzing center distances, space constraints, and calculating stage reductions for a total ratio.

Design an involute gear profile for a 20-tooth gear with module 2 and 40 pitch diameter at 20-degree pressure angle using construction circles, addendum circle, and mirroring.

Design a full set of gear teeth on a gear blank in SolidWorks by creating the addendum circle, mirroring, and extruding a two-stage tooth profile with a 0.6 module fillet.

Master gear design by automating the profile using equations in solidworks, driving dimensions with module, teeth count, and pitch circle diameter through global variables for a parametric, update-ready workflow.

Learn to design a helical gear by applying the helix angle along the pitch circle and arc, using derived sketches and lofting to extend the tooth profile.

Adjust the pitch circle diameter for a helical gear by applying a proportional increase linked to the helix angle, using cosine relations to determine the exact diameter.

Calculate the helix angle to achieve a perfect PCD by adjusting gear tooth counts and module, balancing actual and theoretical diameters to prevent interference.

Discover how the helix angle improves gear engagement and enables achieving the desired center distance by adjusting module, PCD, and tooth counts.

Finalize a gear set by calculating gear widths and intergear gaps, adjust the pitch circle diameter to the actual size, and plan gear counts and clearances for a functional arrangement.

Create the final set of four gears for the SMSR gearbox by adjusting tooth counts and helix angles, using sketch, loft, extrude, and rebuild steps in CAD.
