Method of producing an industrial robot arm

摘要

To mount rotatably supporting members such as a rotary shaft to an arm body of an industrial robot arm, the former and the latter are solidly secured to each other by fastening members such as rivets after a bonding agent is applied to spaces formed between the arm body and the rotatably supporting members, whereby necessity for the stage of assembling work by the welding is eliminated, shearing forces are supported by the bonding agent and tensile forces are supported by the fastening members, so that the robot arm being high in precision and mechanical strength can be obtained.
