Abstract
A series elastic actuator includes a gear configured to rotate, a mounting recess formed on a first surface of the gear, a plurality of elastic bodies configured to be received in the mounting recess that are made of a non-metal elastic material and spaced apart from each other in a circumferential direction, an output body configured to cover the first surface of the gear, and at least one insertion portion configured to protrude from the output body to be inserted between a pair of adjacent elastic bodies or inserted through the elastic bodies.
Claims17
An elastic actuator comprising:
- a gear configured to transmit a rotational force;
- a mounting recess defined on a first side of the gear;
- a plurality of elastic wedges configured to be received in the mounting recess at positions spaced apart from each other in a circumferential direction of the mounting recess, each elastic wedge including a non-metal elastic material;
- an output body configured to cover the first side of the gear;
- and
- at least one insertion wedge protruding from a first side of the output body toward the first side of the gear and configured to be inserted between a pair of adjacent elastic wedges among the plurality of elastic wedges.
