Integrated Planetary Gear System
A complete planetary gear system designed and
assembled in SolidWorks. all core components
modeled from scratch with verified gear meshing,
kinematic motion, and manufacturing-ready geometry.
SYSTEM COMPONENTS DESIGNED:
- Sun Gear — central driver with involute tooth
profile and precise module specification
- Planet Gears (×3) — equally spaced,
synchronized meshing with sun and ring
- Ring Gear (Annulus) — internal tooth geometry
with housing integration features
- Planet Carrier — structural frame maintaining
planet spacing under load
- Output Shaft, Input Shaft, Housing & Fasteners
KINEMATIC ENGINEERING:
- Gear Mates applied for synchronized
multi-gear motion. verified zero-slip
transmission in motion study
- Gear ratio calculated and confirmed through
assembly motion analysis
- All gear interfaces checked for backlash
control and tooth clearance
POWER TRANSMISSION:
- Torque multiplication via planetary
arrangement.. compact high-ratio output
in minimal envelope
- Load distributed across 3 planet gears
simultaneously.. reduces bearing stress
vs. parallel shaft arrangement
DESIGN FOR MANUFACTURING (DFM):
- Metal components: toleranced for CNC
turning and hobbing (gear cutting)
- Carrier and housing: designed for casting
or CNC milling with accessible features
- Polymer prototyping: geometries verified
for FDM 3D printing for rapid validation
SOFTWARE: SolidWorks
DELIVERABLES: Full Assembly + Individual
Part Files + Motion Study
