PURPOSE:To eliminate the need of an oil discharge device by forcedly feeding lubricating oil to a bearing of a winding drum shaft with a pump while the lower surface of a link gear is bathed in lubricating oil stored in a casing. CONSTITUTION:Winding drum shafts are mounted through bearings on a rotating casing 2a at equal distances from the center of rotation, and ring gears 23a, 23b individually driven are engaged with gears of the respective winding drum shafts. The lower surfaces of the ring gears 23a, 23b are bathed in lubricating oil in the casing 2a to lubricate the gears, and a small-sized pump disposed outside a machine body is adapted to suck up lubricating oil through a suction pipe 33 passing through the interior of a sleeve portion 2b to be forcedly fed through a discharge pipe 34 to a bearing supporting the winding drum shafts on the casing 2a with the forward ends of a planetry frame 20 and a metal 36. The thus supplied lubricating oil lubricates the bearing and then the lubricating oil is returned and circulated to be used, which can eliminate the need of an oil discharge device. |
