Design of Thermoelastic Friction Clutch using Numerical Analysis

A thermoelastic friction clutch for transferring mechanical torque is proposed and modeled. Friction clutches are devices used for transferring mechanical torque. They are widely used in numerous industrial, transport, and other applications. Their operation is mostly realized on the mechanical principle. The driving and driven parts are mechanically pressed to one another and the torque is transferred by the friction force acting between them. In other cases, they use the magnetic principle, where the force between the driving and driven parts is produced by magnetic field. The paper deals with a novel clutch based on forces produced by thermoelasticity. The initial design consist of two sets of static permanent magnets and the driving part of this axisymmetric device rotates these two…
