Maximum torque can be transmitted in a Shrink Fit
Maximum torque can be transmitted in a Shrink Fit
(OP)
Hello,
At work we perform a hooping ring on a shaft. The ring and the axis are of steel. Outside diameter of ring = 580mm and inner diameter of the ring or outside diameter of shaft = 470mm. And the interference is 0.65 mm. How do you calculate maximum torque can be transmitted?
Thanks

These are usually simplifications of Lame's equation considering plastic deformation.
You must also consider the burst stresses and deformation consequences (ie if an internal (female) thread for a flange bolt is going to exist on an internal diameter of the shaft).
A lot of this is best done in FEA to confirm the calculator results.
