業機の旋回装置。[Claims for Utility Model Registration] A turning device for a work machine comprising a rotating base mounted on a traveling body so as to be horizontally swivelable, and in particular, the rotating device comprises a ring gear 1 attached to the traveling body or the rotating base.
and a drive pinion gear 3 that is driven by the swing drive hydraulic motor 2 and meshes with the ring gear 1.
and in which the hydraulic motor 2 is controlled to be driven in forward and backward directions and stopped by a hydraulic control device 4, wherein the ring gear 1 is provided with a swing regulating hydraulic motor 5 that is separate from the swing driving hydraulic motor 2. In addition to meshing the interlockingly connected pinion gears 6 for rotation regulation, the two supply/discharge circuits 5a of the hydraulic motor 5 for rotation regulation
, 5b, a control valve 9 is interposed between the pressure oil source 7 and the tank oil path 8, and this control valve 9 is interlocked with the operation of the hydraulic control device 4, so that the hydraulic control device 4 is operated to a forward/reverse drive position. When the swing driving hydraulic motor 2 is being driven forward and backward, the control valve 9 connects the two supply/discharge circuits 5a and 5b of the swing regulating hydraulic motor 5, and the hydraulic control device 4 is operated to the stop position, causing the swing to stop. When the driving hydraulic motor 2 is stopped, the control valve 9 connects one of the two supply/discharge circuits 5a, 5b of the swing regulating hydraulic motor 5 to the pressure oil source 7, and connects the other to the tank oil path 8. A rotating device for a work machine characterized by the following configuration.
