Practical Parts LLC is excited to release our newest product: The Worm Gearbox.
We recognized a lack of options for high reduction lightweight gearboxes. There were also no easy-to-implement options for non-backdrivable gearboxes. This gearbox is perfect for actuating large arms requiring precise control that will be common in this year’s competition.
Practical Parts LLC was founded by two alumni from team 2169, KING TeC, with the purpose of providing unique products that are easy and cost effective to implement for all levels of FRC teams. While working on KING TeC we had lots of “I wish we could buy this off the shelf” moments. Practical Parts is here to make those ideas a reality.
The Worm Gearbox was one of those ideas. While designing arms to actuate the defense in FIRST Stronghold, we were forced to use expensive and hard to control pneumatic pistons. A much better solution would have been to use a motor and a gearbox to achieve more flexibility and better control. However, window motors were very difficult to design a quality coupling for and couldn’t deliver the force required. A setup using traditional gearboxes would have required lots of reduction and thus too much weight and too much cost. The Practical Parts Worm Gearbox would have allowed us to have a lightweight, cost-efficient, well controlled, and powerful arm that wouldn’t stall and burn up motors because, by nature, the worm gears can only be driven by the motor, not the other way around.
Other industrial worm gearboxes regularly exceed hundreds or even thousands of dollars, we are offering our worm gearbox for only $79.99. First units will be shipping out early this week.
