Patent number: 10335944Abstract: A robot wrist structure includes a first wrist element, a second wrist element, and a third wrist element which are respectively rotatable about a first axis to a third axis; drive motors for the second and third wrist elements; and gear sets that reduce speeds of rotation of the drive motors. The gear sets respectively include a driven-side large-diameter gear that rotates the second wrist element and a driven-side small-diameter gear that rotates the third wrist element, where the driven-side large-diameter gear and the driven-side small-diameter gear are coaxially arranged so as to be rotatable about the second axis. The small-diameter gear is fixed to a drive-side bevel gear that meshes with a driven-side bevel gear fixed to the third wrist element. The second wrist element includes a first housing that is fixed to the large-diameter gear; and a second housing rotatably supports the third wrist element.Type: GrantFiled: February 3, 2017Date of Patent: July 2, 2019Assignee: FANUC CORPORATIONInventors: Toshihiko Inoue, Shunsuke Abiko, Tooru Nagai

Patent number: 9717168Abstract: Suppression of the effects of electromagnetic waves on the signals which are transmitted by signal lines and manufacturing composite cables more compactly and with higher efficiency have been sought. For this, provision is made of a composite cable 30 comprised of a center member 32 for supplying the fluid or wire material used for the work of the industrial robot, first signal lines 34 which are arranged at the outer circumferential side of the center member 32, a tubular shield 36 which surrounds the first signal lines 34 and shields them from electromagnetic waves, power lines 40 which are arranged at the outer circumferential side of the shield 36, and a tubular sheath 42 which surrounds the power lines 40.Type: GrantFiled: January 13, 2016Date of Patent: July 25, 2017Assignee: Fanuc CorporationInventors: Toshihiko Inoue, Shunsuke Abiko

Patent number: 9597808Abstract: A joint structure capable of optimizing a margin of length of an umbilical member corresponding to a motion range of a forearm, and an industrial robot having the joint structure. At an upper section (near the forearm) of an upper arm, a frame constituting the upper arm has an opening through which the umbilical member can be inserted, and the umbilical member 28 inserted from the opening into a space (or containing section) within the upper arm. By virtue of such a containing section, even when the motion range of the forearm is changed, an operator can adjust (optimize) the margin of length of the umbilical member required for the motion of the forearm.Type: GrantFiled: October 13, 2015Date of Patent: March 21, 2017Assignee: Fanuc CorporationInventors: Toshihiko Inoue, Shunsuke Abiko
