発明の名称 (英語) LOAD-COMPENSATION DEVICE コモンズ
発明の概要(英語) Provided is a load-compensation device that can compensate for the load on an actuated arm and has excellent safety and durability. An actuated arm (104) is supported on a support body (102) by a first pivot part (103), an actuation cylinder (105) is supported above the first pivot part (103) by a second pivot part (107), and a piston rod (108) of the actuation cylinder (105) is coupled to a third pivot part (109) on the actuated arm (104). A piston rod (112) of a compensation cylinder (110) is coupled to a movable frame (113), and a compression coil spring (114) that pushes the moveable frame (113) upwards biases a piston (112A) in the compensation cylinder (110) upwards. The actuation cylinder (105) and the compensation cylinder (110) are coupled by a conduit (115). When the actuated arm (104) is rotated, the displacement of the piston in the actuation cylinder (105) biases the piston in the compensation cylinder (110), generating a torque that balances the load torque from the load (W) on the actuated arm (104), thereby maintaining a balanced state regardless of the angle of the actuated arm (104).
