Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a robot comprising two joint parts that can be attached to ends of arms in a connected state, which can increase a connection strength of two joint parts, as well as accurately connect the two joint parts.

SOLUTION: A joint part 2 of a robot 1 comprises: a case body 11 encasing a motor and a reducer. An output side member 27 including a flange part 27a is fixed to an output shaft of the reducer. An opening part is formed in the case body 11, and opens in a direction orthogonal to an axial direction of the output shaft of the reducer. A plain-shaped attachment surface orthogonal to the opening direction of the opening part is formed in the opening part. The robot 1 comprises: multiple two-axis-joint units 6 each constituted of two joint parts 2. To the robot 1, an attachment surface of the case body 11 for one of the joint parts 2A. 2D. 2E constituting the two-axis-joint units 6, and a flange part 27a for the other one of the joint parts 2B, 2C, 2E, are fixed through a connection member 63 or directly.

【課題】連結された状態でアームの端部に取り付けられる2個の関節部を備えるロボットにおいて、2個の関節部の連結強度を高めることが可能で、かつ、2個の関節部を精度良く連結することが可能なロボットを提供する。
【解決手段】ロボット1の関節部2では、モータおよび減速機がケース体11に収容され、減速機の出力軸にフランジ部27aを有する出力側部材27が固定されている。ケース体11には、減速機の出力軸の軸方向に直交する方向に開口する開口部が形成され、開口部には、開口部の開口方向に直交する平面状の取付面が形成されている。ロボット1は、2個の関節部2によって構成される2軸関節ユニット6を複数備えている。このロボット1では、2軸関節ユニット6を構成する一方の関節部2A、2D、2Eのケース体11の取付面と他方の関節部2B、2C、2Eのフランジ部27aとが連結部材63を介してまたは直接固定されている。
