Art aligned
27 December 2014
HepcoMotion’s HDRT rings have been singled out to feature in a David Černý statue of Franz Kafka, a stone’s throw from Prague’s Old Town, where they will rotate sections of the installation’s face.
The massive monument has a profile split into 42 rotating layers that will become aligned at a particular moment in their cycle to reveal the famous writer’s face in all its glory. The HepcoMotion rings, made from stainless steel to prevent corrosion, will act as large 1.6 m diameter bearings supporting and rotating each of the layers.
The HDRT ring design incorporates an external vee profile and six high-capacity stainless steel vee bearings for ring guidance. The ring has a gear cut into its internal diameter to provide a rack-and-pinion motor driven solution. The integral gear is highly concentric to the ring vee to ensure smooth precision movement throughout the rotation.
