Abstract
Official abstract text for this publication.
A joint structure for a robot of the present invention includes: a first member; a speed reducer coupled to one surface of a wall portion of the first member; a motor located at a side opposite to the one surface of the wall portion of the first member; a first gear attached to a shaft of the motor; a second gear attached to a shaft of an input unit of the speed reducer and intermeshing with the first gear; and a second member attached to an output unit of the speed reducer. The diameter of the second gear is larger than a coupling unit that couples to the first member. The first member is provided with a gear accommodating portion that accommodates the first and second gear, a part of the gear accommodating portion which covers at least the second gear is removable with respect to the first member.
First claim
Opening claim text (preview).
What is claimed is: 1 . A joint structure for a robot, comprising: a first member; a speed reducer coupled to one surface of a wall portion of the first member, a shaft of an input unit of the speed reducer being passed through the wall portion; a motor located at a side opposite to the one surface of the wall portion; a first gear attached to a shaft of the motor; a second gear attached to the shaft of the input unit and intermeshing with the first gear; a second member attached to an output unit of the speed reducer, wherein the second gear has a larger diameter than a diameter of a coupling unit of the speed reducer which couples to the first member, the first member is provided with a gear accommodating portion that accommodates the first gear and the second gear which intermesh with each other, and a part of the gear accommodating portion which covers at least the second gear is attachable and removable with respect to the first member. 2 . The joint structure for a robot according to claim 1 wherein: the gear accommodating portion is formed by a cover member covering the first gear and the second gear which intermesh with each other; and the cover member is removably fixed to the first member, and the motor is held at the cover member. 3 . The joint structure for a robot according to claim 1 , wherein the gear accommodating portion comprises: a motor holding portion formed integrally with the first member, the motor holding portion accommodating the first gear and holding the motor; and a cover member removably fixed to the first member and covering the second gear.
