Gear Types for Different Motion Systems
Select the closest structure, then define tooth data, shaft arrangement, interfaces, load, speed, lubrication and required accuracy.
Spur & Helical Gears
External gears for parallel-axis drives, from direct engagement to smoother helical motion.
Internal & Ring Gears
Compact internal-tooth and annular structures for planetary and circular assemblies.
Bevel Gears
Angle-drive gears for intersecting or offset shaft arrangements.
Worm Gears
High-ratio worm and wheel sets for skew-axis transmission.
Gear Racks
Linear tooth elements paired with pinions for controlled travel.
Gear Shafts & Compound Gears
Integrated teeth, shafts, hubs and multiple stages with controlled datum relationships.
Material Selection
