Worm Drive

3D Model

Worm Drive Components:

• Worm on wormshaft: Machined from free-cutting steel (ETG100), Ref. 15 TSn 27, Kremp Wetzlar
• Worm wheel: Copper-tin bronze (EN CC 483 K), Ref. 15 Sr 25, Kremp Wetzlar

Gear Configuration: One gear right (i.e., single start right-handed), module 1.5, 25-tooth worm wheel.

➜ 1:25 reduction ratio (25 wormshaft rotations per single worm wheel revolution).

Design and Animation:

• CAD models retrieved from traceparts.com.
• Worm drive refined using ANSYS SpaceClaim (worm wheel’s 3D model was provided with partial tooth geometry).
• Assembly exported as an .OBJ file.
• Animation created in Blender v. 3.6
• Final rendering optimized in Sketchfab
