Compact structure The transmission axial dimension can be shorten, compact because of the transmission structure in the planet carrier's bearing spindle. Big bearing capacity Because curvature radius of the hypocycloid is bigger than that of the epicycloid in the same conditions, its bearing capacity is bigger than that of the epicycloid. Stable drive and long working life Using 2-level reducing structure makes the low-speed cycloid pinwheel planetary reducer more stable, and the tumbler bearing's working life greatly increases because its quantity increases and the inside/outside ring speed drops. Small backlash Optimized design gains small manufacture error, high motion precision and small backlash . Good output rigidity The hypocycloid planetary transmission's output structure uses embedded cross roller bearing which two ends are supported as possible as to gain big rigid disc output structure, which rigidity is more than that of RV cycloid reducers' output structure (angular contact bearing structure) with greatly improved shock resistance. Hollow structure Hollow structure is conveniently to layout the robot, to shorten its base dimension and protect it from be winded.
