Zusammenfassung:The present invention relates to a rotation drive. The rotation drive according to the present invention comprises: a driving block which has a plurality of valves along a hydraulic line, and receives a hydraulic oil from a hydraulic pump in the hydraulic line and guides flow of the hydraulic oil through the plurality of valves; a hydraulic motor which receives the hydraulic oil from the hydraulic line of the driving block and converts a fluid energy of the hydraulic oil into a rotation energy of a mechanical element; and a rotation platform in combination with the hydraulic motor, which rotates a lower part arm relative to an upper part arm when the hydraulic motor operates. A plurality of hydraulic motors are located at the rotation platform along the circumference of the rotation platform. 본 발명에 따른 회전 드라이브는, 유압 라인을 따라 복수의 밸브를 가지고, 유압 라인에 유압 펌프로부터 작동유를 공급받아 복수의 밸브를 통해 작동유의 흐름을 유도하는 구동 블럭; 구동 블럭의 유압 라인으로부터 작동유를 공급받아 작동유의 유체 에너지를 기계 요소의 회전 에너지로 변환시키는 유압 모터; 및 유압 모터와 결합하여 유압 모터의 작동시 상부 아암에 대해 하부 아암을 회전시키는 회전대를 포함하고, 유압 모터는, 회전대의 둘레를 따라 회전대에 복수로 위치된다.
