Title:
SERIES ELASTIC LINEAR ACTUATOR
Document Type and Number:
Japanese Patent JP2019097270
Kind Code:
A
Abstract:
To provide a series elastic linear actuator which can be specifically applied to a field such as a humanoid robot and a rehabilitation support mechanism.SOLUTION: A series elastic linear actuator A includes: a liner driving mechanism 1A; a power output member 2A; and an elastic member 3A. The liner driving mechanism 1A comprises: a stepping motor 10A; a screw rod member 12A; and a linearly moving member 13A. The screw rod member is communicated with the stepping motor, and the linearly moving member is provided at the stepping motor side so as to be connected with the screw rod member, and performs linear reciprocating-motion along a power input direction by the driving of the screw rod member. The power output member 2A is installed on one side of an axial direction in the linearly moving member, and performs the liner reciprocating-motion along a power output direction matching the power input direction. The elastic member 3A is provided between the linearly moving member and the power output member, and comprises an energization force toward the power input direction.SELECTED DRAWING: Figure 1
