The Dynamics of Compliant Rotational Power Transmissions

An Oldham coupling is a constant velocity rotational transmission between two misaligned but parallel axis. Conventionally, this coupling uses two sliding contact prismatic joints, in which friction, wear, backlash and lubrication is unavoidable. Conversion to a compliant mechanism, in which motion is accomplished by elastic deformation instead,...

Rotational stiffness in compliant mechanisms: theory, method and application

Compliant mechanisms accomplish their function due to the elastic deformation of their elements rather than using the relative motion of rigid bodies. Thereby the drawbacks of sliding friction, including wear and hysteresis are eliminated. Besides that compliant mechanisms allows monolithic production which facilitates cost reduction and...
