Compliant Joint Reconstruction

Metamorphic Flexure Bearings

Mechanical devices often feature rotational motion, achieved through the use of bearings or hinges. However, at high frequency of loading, these bearings will wear and necessitate maintenance. Longevity of devices can therefore be extended if the wear on the bearings is reduced.

Our device, the metamorphic flexure bearing, combines two distinct mechanical stages in series to provide the precision and longevity of compliant mechanisms with an extended range of motion as needed. The first stage is a flexure based bearing that offers precise, frictionless, wear-free rotation, albeit over a limited range of motion. The second stage is a traditional bearing that provides extended range of motion as needed. A magnetic or spring-based retention mechanism ensures smooth switching between the two stages.
