Description
The ION Round Belt System provides a simple and adaptable way to transfer power in compact robot mechanisms. Designed around a 2in outer diameter when the belt is installed, the system stays on pitch with the REV ION wheel lineup, making it easy to integrate into intakes, conveyors, feeders, and other custom assemblies. At its core is a solid polyurethane round belt that can be cut to length and heat welded to form custom closed loops. Trimming the belt about 8 percent shorter than the final path helps account for stretch after welding and ensures proper tension once installed.
Two pulley options allow teams to match the system to their preferred shaft style. The Round Belt Pulley with a 1/2in hex bore is a compact solution for direct driven shafts and includes a 1in bolt circle for alternate mounting methods. A single sided bearing race boss makes it possible to stack multiple pulleys, and teams needing bearing contact on both sides can add the 1/2in Hex Shaft Spacer 1/8in (REV-21-2004-PK10). The MAXSpline version offers the same belt driven outer diameter in a lighter, narrower profile that integrates cleanly with the MAXSpline ecosystem. Using either pulley allows the system to work with the matching shaft option, while the design also supports easy integration of multiple belts.
The Polyurethane Round Belt itself is flexible, durable, and well suited for light power transmission tasks such as intakes and conveyors. Its ability to be welded into custom lengths gives teams the freedom to build mechanisms around the geometry they need, while the compliant belt and glass filled nylon pulleys provide smooth and low maintenance operation.
