    Abstract: A joint structure for a robot according to the present disclosure includes a first link and a second link rotatably coupled to each other via a joint part. The joint part has a first rotary member disposed so that an axial center thereof is oriented in a first direction and connected to the first link, a pair of second rotary members disposed so that an axial center thereof is oriented in a second direction perpendicular to the first direction, and so as to engage with the first rotary member, and a shaft member formed in a T-shape and having a first shank and a pair of second shanks. The joint structure further includes a pressing member connected to the second shank and configured to press the second rotary member inwardly.

    Abstract: Disclosed are a waist structure of a robot. The waist structure includes: a fixed platform, a connector, a movable platform, a load-carrying bearing and two motors arranged on the fixed platform, and two drive assemblies. The connector includes first and second ends facing away from each other; the first end is provided with a yaw shaft connected to an inner ring of the load-carrying bearing; and the second end is provided with a pitch shaft rotatably connected to the movable platform. Each drive assembly corresponds to one motor, and the drive assemblies are connected to the movable platform and the corresponding motors. The motors can actuate the drive assemblies to drive the movable platform to rotate relative to the connector in an axial direction of the pitch shaft and the connector to rotate relative to the fixed platform in an axial direction of the yaw shaft.

    Abstract: A robot includes one or more joints. At least the one joint includes: a first joint member and a second joint member disposed so as to be relatively rotatable around a predetermined axis; a reducer that relatively rotatably supports the first and second joint members around the axis on one side in a direction of the axis of the first joint member; and a bearing that supports the first and second joint members relatively rotatably around the axis and relatively movable in a direction along the axis on another side in the direction of the axis of the first joint member, the first and second joint members include respective flange surfaces perpendicular to the axis and facing each other in the direction of the axis, and each of the flange surfaces includes a screw hole or a through hole for closely adhering the flange surfaces by fastening of a bolt.

    Abstract: A joint for transmitting movements between articulated elements of a parallel kinematics robot has at least two degrees of freedom and includes: a first housing, a second housing arranged rotatable in relation to the first housing about a first axis, and a shaft arranged rotatable in relation to the second housing about a second axis which coincides with a longitudinal axis of the shaft. The shaft is arranged rotatable in relation to the second housing by at least a first angular contact bearing. In applications where one of the revolute pairs of a joint is subjected to radial and axial forces of similar order, and another one is subjected almost solely to radial forces, it is advantageous to manage the forces of the prior by means of an angular contact bearing or bearings configured to bear both radial and axial loads, whereby a joint with very small backlash in a particularly compact design can be achieved.

    Abstract: An industrial robot may include a main body part; a plurality of levers having base end sides turnably connected with the main body part; a plurality of arm parts having respective base end sides turnably connected with respective tip end sides of the plurality of the levers; a movable part which is turnably connected with the respective tip end sides of the plurality of the arm parts; and a plurality of turning drive mechanisms for respectively turning the plurality of the levers. The plurality of the levers may radially extend to an outer peripheral side of the main body part at a substantially equal pitch. The arm part may provided with two arms which are mutually parallel to each other and are formed in a straight shape.
