    • 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.
    • 旋转粘度计包括被驱动以在液体中旋转的转子,其粘度被测量。 第一驱动轴或转子轴支撑转子并向转子传递旋转驱动力。 旋转驱动装置具有用于驱动转子的马达,其具有用于提供驱动力的输出轴。 第二驱动轴将来自马达的驱动力传递到转子轴。 第一连杆将马达的输出轴与第二驱动轴弹性连接,以便传递其间的驱动力。 支撑件包括用于可旋转地支撑电动机轴的枢轴和轴承以及将转子轴与第二轴连接的支撑件的第二连杆。 检测器检测输出轴和转子轴之间的角位移。 枢轴保护器具有锁定机构,用于锁定转子轴不旋转并用于使锁脱开。 枢轴分离机构分离并接合支架的枢轴和轴承。 控制器控制电机和枢轴保护器。
