Abstract
This robot is provided with a power transmission gear train for driving a joint. The robot is provided with a first gear, a second gear, and a lubrication gear. The second gear has a diameter larger than that of the first gear, and meshes with the first gear. The lubrication gear meshes with the first gear. The rotatable angle range of the joint is limited. The joint is caused to rotate within said rotatable angle range by rotary-driving the first gear in a state of being meshed with the second gear. The lubrication gear is formed of an oil-containing resin.
Claims7
A robot equipped with a power transmission gear train for driving a joint comprising:
- a first gear;
- a second gear that has a larger diameter than a diameter of the first gear and meshes with the first gear;
- and
- a lubrication gear that meshes with the first gear, wherein
- a a rotation angle range of the joint is restricted,
- a the first gear meshed with the second gear is rotationally driven to cause the joint to rotate within the rotation angle range, and
- a the lubrication gear is made of oil-containing resin.
A robot lubricating method of lubricating a first gear included in the robot, wherein
- a a rotation angle range of a joint of the robot is restricted,
- a the first gear meshes with a second gear having a larger diameter than a diameter of the first gear,
- a the first gear meshed with the second gear is rotationally driven to cause the joint to rotate within the rotation angle range,
- a a lubrication gear made of oil-containing resin meshes with the first gear, and
- a lubrication is performed by a driven rotation of the lubrication gear in accordance with a rotation of the first gear.
