ABSTRACT:
A rotary viscosimeter includes a rotor driven to rotate in a liquid, the viscosity of which is to be measured. A first drive shaft or rotor shaft supports the rotor and transmits a rotary driving force to the rotor. A rotary driving apparatus has a motor for driving the rotor with an output shaft for supplying the driving force. A second drive shaft transmits the drive force from the motor to the rotor shaft. A first link elastically links the output shaft of the motor with the second drive shaft to transmit the driving force therebetween. A support includes a pivot and a bearing for rotatably supporting the motor shaft and second link which by-passes the support for linking the rotor shaft with the second shaft. A detector senses the angular displacement between the output shaft and the rotor shaft. A pivot protector has a locking mechanism for locking the rotor shaft from rotating and for disengaging the lock. A pivot separating mechanism separates and engages the pivot and the bearing of the support. A controller controls the motor and pivot protector.
