“Use the tool, Lena,” Tom said. “You’re an engineer, not a cartographer.”
Lena scoffed. Add-ins were crutches. Real designers built their own geometry. But with the deadline looming and the memory of the test rig’s screeching metal still in her ears, she downloaded the trial. solidworks geartrax
Installing GearTrax into SolidWorks 2024 was seamless. A new toolbar appeared, its icon a stylized, perfect gear tooth. She clicked it. “Use the tool, Lena,” Tom said
She assembled the components in SolidWorks. The sun gear meshed with the planets like they were dancing. The ring gear slid over them with exactly 0.02mm of radial clearance. She ran a motion study. The rotation was silky, the contacts transferring load from one tooth to the next with textbook precision. For the first time in a month, Lena smiled. Real designers built their own geometry
Two weeks later, the physical Mark VII Actuator was assembled. The gears, cut from hardened 9310 steel by a CNC hobber using the DXF profiles GearTrax had exported, fit together without a single file stroke from a machinist. They lowered the actuator into the test bath, filled it with 5W-30 oil, and ran the torque meter.
The dialog box that opened was intimidating at first. It wasn't a toy. It was a cockpit. She set the gear type: External Spur . Then the real work began. She input the module (2.5), the number of teeth (24), the pressure angle (20°), and the face width (35mm). Then came the advanced fields: Profile Shift Coefficient to balance specific sliding, Backlash to 0.05mm, and Root Fillet Radius for fatigue life.
