Re: Uses of CIMS and associated reductions
Do mini-CIMs count?
2009 (1714): One CIM on the shooter, run through an AM Planetary after the first event to lower range and increase consistency. One CIM through a standard Toughbox and belt reduction for the elevator. No problems that I know of.
2010 (2791): One CIM operated a hanging winch. COTS options for high reductions were scarce, so we ran the CIM through an AM Planetary and the Toughbox Nano, with a very small diameter winch at the end. Needed a steel output shaft.
2013 (2791): One CIM through a ~900:1 reduction, another CIM is direct driving a 4 7/8" wheel. Will update with results once these mechanisms move. The 900:1 gearbox is TB3 internals followed by two VexPro custom reductions - PM for details. I think it is five stages.
High reduction gearboxes are a general challenge in FRC. In 2011 in particular, finding a COTS solution for an arm that didn't involve a Window motor was extra tricky. For our final event, we ran a 775 through a CIMulator through an AM Planetary through a Toughbox Nano and chain reduction. Craziest COTS gearbox ever made.
