Abstract
Official abstract text for this publication.
A robot includes one or more joints. At least the one joint includes: a first joint member and a second joint member disposed so as to be relatively rotatable around a predetermined axis; a reducer that relatively rotatably supports the first and second joint members around the axis on one side in a direction of the axis of the first joint member; and a bearing that supports the first and second joint members relatively rotatably around the axis and relatively movable in a direction along the axis on another side in the direction of the axis of the first joint member, the first and second joint members include respective flange surfaces perpendicular to the axis and facing each other in the direction of the axis, and each of the flange surfaces includes a screw hole or a through hole for closely adhering the flange surfaces by fastening of a bolt.
First claim
Opening claim text (preview).
The invention claimed is: 1. A robot comprising one or more joints, wherein at least the one joint includes: a first joint member and a second joint member disposed so as to be relatively rotatable around a predetermined axis; a reducer that relatively rotatably supports the first joint member and the second joint member around the axis on one side in a direction of the axis of the first joint member; and a bearing that supports the first joint member and the second joint member relatively rotatably around the axis and relatively movably in a direction along the axis on another side in the direction of the axis of the first joint member, the first joint member and the second joint member include respective flange surfaces perpendicular to the axis and facing each other in the direction of the axis, and each of the flange surfaces includes a screw hole or a through hole for closely adhering the flange surfaces by fastening of a bolt. 2. The robot according to claim 1 , wherein the second joint member includes a fitting surface capable of fitting a surface to be fitted of the reducer in the direction along the axis in a state in which the flange surfaces are closely adhered to each other. 3. The robot according to claim 2 , wherein the fitting surface comprises a cylindrical inner surface disposed coaxially with the axis.
