Cycloidal Reducers
High shock-load capacity, compact cycloidal speed reducers designed to withstand high impact forces without tooth breakage in heavy robot joints.
Cycloidal drives provide superior shock resistance over harmonic sets. Cone Drive sells precision cycloidals (incorporating Spinea technology) out of Traverse City, MI. Emerging dual-use domestic actuators also target this mechanism for heavy humanoid and quadruped impact joints.
