Abstract
The gravity compensation mechanism includes a first non-circular gear configured to rotate about a rotation axis of an arm part of the robot together with the arm part, a second non-circular gear driven by the first non-circular gear, and an extension/contraction body configured to extend and contract to produce force as the second non-circular gear rotates, one end portion of the extension/contraction body being connected to the second non-circular gear.
Claims11
A gravity compensation mechanism comprising:
- a first non-circular gear configured to rotate about a rotation axis of an arm part of a robot together with the arm part;
- a second non-circular gear driven by the first non-circular gear;
- and
- an extension/contraction body configured to extend and contract to produce force as the second non-circular gear rotates, a one end portion of the extension/contraction body being connected to the second non-circular gear.

A gravity compensation mechanism comprising:
- a first non-circular gear configured to rotate together with a swing part of a robot, the swing part configured to swing about a pivot which intersects with a vertical axis;
- a second non-circular gear driven by the first non-circular gear;
- and
- an extension/contraction body configured to extend and contract to produce force as the second non-circular gear rotates, a one end portion of the extension/contraction body being connected to the second non-circular gear.
