Torque generated by hub deformation
Torque generated by hub deformation
(OP)
hi,
i would to create an hub able to brake a shaft using oil pressure. I put under pressure, the hub deforms itself and i obtain a torque on the inner shaft.
i will take an H6/g5 tolerance and i would to know how to calculate the torque.
with Ansys i obtained a deformation trace:
.
In yellow the hub tolerance space, in green the shaft tolerance space and in red the warped hub shape
I obtain an interference of 9 µm over 5 mm. using classical formulae for finding pressure and torque i obtained a very little value: ~4Nm


what procedure should i use in your opinion?

RE: Torque generated by hub deformation
Hub shaft connections from ETP in Sweden work in the same hydraulic principle.
These are double walled hardened steel sleeves filled with grease and one screw to pressurize.
