Title: Brake dynamometer with flexible stator bearing - uses eccentric deflection to compensate for misalignment in rotor shaft
Inventor: WEINLICH LEOPOLD
IPC: G01M15/02
Filed: 1980-02-20
Abstract: The brake dynamometer with a stator deflecting about a fixed axis is coupled to a measured drive machine and is designed to maintain the axis stationary within the specified measurement range. Alignment errors with the drive machine shaft are almost eliminated. No complicated correction linkages are therefore required. The eccentrically offset positioning of the stator (3) w.r.t the rotor shaft (4) is achieved elastically so that when a torque is applied to the stator the stator deflection axis coincides with that of the rotor shaft. This arrangement ensures that all possible deflections of the rotor shaft (4) resulting from the elasticity of the support and the measurement device are compensated for all torques falling within the measurement range.
