Making Smarter Screw Starter Drives in the USA Makes More Sense
MAYWOOD, IL.—For 50 years and more, screw starter drives have served reliably with a distinct purpose. But they have evolved over the decades out of necessity. Today’s vehicles may operate with higher voltage.
No manufacturer in the mid-20th century could have foreseen that this equipment would need to adapt to the increased electrical power supply required for 21st century vehicles.
It wasn’t until now that innovation from Weldon/ Van Bergen and Greener, Inc. could make the traditional standard screw starter drive respond to the increased voltage needed to run engines today.
Higher voltages can put additional force and torque on the starter drive. This can cause the starter drive to not perform as needed.
To compensate, Weldon upgraded to use only alloyed stopnuts that are screwed and staked on securely. Original specs have to be exceeded because no manufacturer foresaw this equipment being operated with higher voltage after seven or eight decades of use. Springs, too, have to be speced to handle large torsion loads.
Weldon/Van Bergen also manufacture the mating gear and shaft on CNC machines situated next to each other. This proximity ensures that the gears and shaft engage easily and without sticking-- a huge problem before. The precision machining and deburring alleviate the sticking substantially.
“Preventing sticking is on our mind and this drive and its components are all USA-manufactured,” said Paul Weldon, owner of Weldon/Van Bergen, a small, American owned and operated company specializing in starter drives for the past 90 years.
