Abstract: A ceiling-mounted SCARA robot includes: a base, a first arm that is connected to the lower side of the base via a first coupling part centering around a first articulated shaft and that can pivotally move around the first articulated shaft within a horizontal plane, a second arm that is connected to the lower side of the first arm via a second coupling part centering around a second articulated shaft and that can pivotally move around the second articulated shaft within a horizontal plane, a working shaft that is mounted on the second arm, a second articulated shaft motor and a second articulated shaft reducer for driving the second arm, and a working-shaft rotation motor that rotates the working shaft. The second articulated shaft reducer is provided on the second coupling part, and the working-shaft rotation motor is arranged directly below the second articulated shaft reducer.

Abstract: A ceiling-mounted SCARA robot includes a base, a first arm that is connected to the base via a first coupling part centering around a first articulated shaft and that can pivotally move around the first articulated shaft as a center of pivotal movement within a horizontal plane, a second arm that is connected to the first arm via a second coupling part centering around a second articulated shaft and that can pivotally move around the second articulated shaft as a center of pivotal movement within a horizontal plane, a working shaft that is mounted on the second arm, and a base mounting part that is mounted on the base and places the base on a beam as a structural body for mounting located at a position vertically above an operating area of the working shaft.

Abstract: There is provided a pivoting apparatus of an industrial robot including: a brake 40 that is fixed to a motor shaft 30s of a motor 30 to halt the motor 30; an encoder 50 that is fixed to the motor shaft 30s to detect the pivoting angle of the motor 30; a speed reducer 60 that is coupled with the motor shaft 30s to form a communicating hollow portion, that is fixed to and coupled with a pivoting-side arm 20, and that reduces the rotation speed of the motor 30; a pipe-supporting bearing 72 that is provided in a fixed-side arm 10 and that is communicated with the communicating hollow portion; and a low-speed pivoting pipe 70 whose one end is fixed to and coupled with the pivoting-side arm 20 and the other end of which is fixed to the pipe-supporting bearing 72, and through which a cable 80 is wired.
