Planetary gear collection, accurately modeled and ready for use in CAD and 3D print applications. Modeled in Autodesk Inventor and provided in multiple file formats (IPT/IAM, STP, SAT, IGS, and STL). Gears are constructed with modular geometry, allowing them to be combined in an endless variety of ways. Easily create complex power transmission systems that produce rotational motion, speed multipliers, and torque multipliers. Perfect for both digital and physical mechanical design projects.

Native Autodesk Inventor 2012 files are provided with intact browser trees and parameter tables to allow full configurability and customization.

Collection includes 4 planetary gear systems:

• 8-Tooth sun gear, 8-tooth planet gears, 24-tooth ring gear, and 24-tooth carrier gear (4:1 reduction ratio)
• 16-Tooth sun gear, 8-tooth planet gears, 32-tooth ring gear, and 32-tooth carrier gear (3:1 reduction ratio)
• 16-Tooth sun gear, 16-tooth planet gears, 48-tooth ring gear, and 48-tooth carrier gear (4:1 reduction ratio)
• 32-Tooth sun gear, 8-tooth planet gears, 48-tooth ring gear, and 48-tooth carrier gear (2.5:1 reduction ratio)

Collection includes 3 ring gear configurations and 6 spur gear configurations:

• Ring gear, 32-tooth external, 24-tooth internal (2.00in external pitch diameter, 50.8mm external reference diameter)
• Ring gear, 48-tooth external, 32-tooth internal (3.00in external pitch diameter, 76.2mm external reference diameter)
• Ring gear, 64-tooth external, 48-tooth internal (4.00in external pitch diameter, 101.6mm external reference diameter)
• Spur gear, 8-tooth, round bore (0.50in pitch diameter, 12.7mm reference diameter)
• Spur gear, 8-tooth, D-profile bore (0.50in pitch diameter, 12.7mm reference diameter)
• Spur gear, 16-tooth, round bore with keyway (1.00in pitch diameter, 25.4mm reference diameter)
• Spur gear, 24-tooth, round bore with keyway (1.50in pitch diameter, 38.1mm reference diameter)
• Spur gear, 32-tooth, round bore with keyway (2.00in pitch diameter, 50.8mm reference diameter)
• Spur gear, 48-tooth, round bore with keyway (3.00in pitch diameter, 76.2mm reference diameter)

All gear tooth profiles are precisely modeled with accurate arc-based geometry and a small amount of backlash to ensure proper engagement. All gears can be used as drive gears (rotationally locked to shaft) or idle gears (free spinning about shaft).

All gears are provided with a diametrical pitch of 16 teeth/inch (module 1.6). All gear bores are designed for a 0.25in (6.35mm) nominal shaft size. All gears have a 0.25in (6.35mm) face width. Gears can be easily scaled to create any diametrical pitch or module that you may need.

The centerline distance between any two mating gears is ( First Gear Pitch Diameter + Second Gear Pitch Diameter ) / 2.

All gears are provided in 5 file formats:

• IPT/IAM (Autodesk Inventor 2012 format for CAD)
• STP (general solid model format for CAD)
• SAT (general solid model format for CAD)
• IGS (general solid model format for CAD)
• STL (general surface model format for 3D print)

Product also includes a Read Me text file (TXT format) detailing the physical dimensions of all gears.
