CUSTOM SLIP CLUTCH ROLLER:Four friction surfaces to allow for high speed rotation and "constant" slippage. Wave spring loaded to generate required drive force while still allowing constant slip. Uses off the shelf hardened steel thrust bearing washers, fiberglass friction washers, needle bearings and radial bearings. Hubs were designed to be 3d printed from Onyx with cartridge brass insert sleeves for minutes at a time. Pinch roller on drive pulley is present so these can be designed into a radial pattern and all driven from a single timing belt. Run for a couple of minutes at a time and tens of hours total on a First Robotics FRC robot successfully with zero failures. No guarantees for life span or continuous duty.
