Abstract
A conveyance device includes a fixed base having a large gear, a turning body supported by the fixed base via a bearing, two or more servomotors, a conveyance arm, and two or more speed reducers. The speed reducer includes a housing integrated with the turning body, a planetary carrier rotatably supported inside the housing, an internal gear provided inside the housing, a sun gear connected to an output shaft of the servomotor, a plurality of planetary gears arranged around the sun gear and rotatably supported by the planetary carrier, and an output gear rotating integrally with the planetary carrier. The planetary gear meshes with the sun gear and meshes with the internal gear. The output gear has a smaller diameter than that of the large gear and meshes with the large gear outside the large gear.
Claims6
A conveyance device comprising:
- a fixed base including a large gear serving as an external gear;
- a turning body supported by the fixed base via a bearing;
- two or more servomotors configured to rotate the turning body relative to the fixed base;
- a conveyance arm configured to be able to convey a workpiece by turning in conjunction with the turning body;
- and
- two or more speed reducers fixed to the turning body and respectively connected to the two or more servomotors, wherein:
- the speed reducer includes a housing integrated with the turning body, a planetary carrier rotatably supported inside the housing, an internal gear provided inside the housing, a sun gear connected to an output shaft of the servomotor, a plurality of planetary gears arranged around the sun gear and rotatably supported by the planetary carrier, and an output gear configured to rotate integrally with the planetary carrier;
- the planetary gear meshes with the sun gear and with the internal gear;
- and
- the output gear has a smaller diameter than a diameter of the large gear and meshes with the large gear outside the large gear.
