Abstract:

A fluid coupling device for coupling torque between two members and utilizing a magnetorheological fluid having a controllable yield strength in shear in response to a magnetic field and having a determinable viscosity in the absence of a magnetic field and with the coupling device having a rotor, rotatably supported in a cavity in a housing with the cavity filled with the magnetorheological fluid and with the cavity and rotor having similarly shaped contours and constructed to concentrate the magnetic coupling effect through the fluid at the radially outer end of the rotor and a torque load simulator system utilizing the fluid coupling for determining the performance of a torque tool or other torque related apparatus relative to a predetermined standard of performance.
