3D Printed Star Wheel Corrects Belt Seating Issue
Dave Winters, a process engineer at Fenner Drives, needed to correctly seat a power transmission belt on an idle gear for trimming.
The current steel wheel had teeth that were 1/16” too long. This prevented the belt from falling flush against the gear. Without this proper seating, the trimming wheel would not accurately trim the belts.
The team used Armadillo™ semi-rigid 3D filament to create a model with reduced teeth height to achieve the function desired.
The traditional solution for this design would have taken over $500 of machining time. By 3D printing the gear total cost was less than $50, including engineer design time and materials.
The printed solution saved the company $450 in machine time and up to 3 weeks of turnaround time.
“By 3D printing the star wheel before investing in tooling, we kept the machines running and saved the cost of an incorrect tool.” – Dave WintersSHOP ARMADILLO – $47.99 »
