DEVICE FOR REGULATING STIFFNESS

摘要

The present invention relates to a stiffness regulating device which can transmit the driving force of a drive motor to a driven member with wanted stiffness. The stiffness regulating device includes a rotating shaft connected to the driven member to rotate the driven member; a rotary connecting member connected to the rotating shaft to be able to free rotate, and rotated by receiving the driving force of the drive motor; and a resilient connecting member fixed to the rotating shaft and extending in a longitudinal direction of the rotating shaft to be connected to the rotary connecting member. The resilient connecting member applies the resilient force in a direction opposite to a rotation direction of the rotary connecting member to prevent the free rotation of the rotary connecting member with respect to the rotating shaft. When the rotary connecting member is rotated by the drive motor, the resilient force of the resilient connecting member serves as the stiffness so that the rotating force of the rotary connecting body is transmitted to the rotating shaft.
