<p>PROBLEM TO BE SOLVED: To provide a hydraulic rotating device capable of efficiently using energy of water and avoiding temperature rise of a speed reducer. SOLUTION: A hydraulic turbine chamber 18 to open a water ejection port 20a and with a built-in hydraulic turbine 21 and a reduction gear chamber 19 with a built-in gear of a reduction gear 22 to output by decelerating rotational speed of the hydraulic turbine 21 are furnished, the hydraulic turbine chamber 18 and the reduction gear chamber 19 are divided from each other by a partition wall 23a, both chambers 18, 19 are communicated to each other by a water channel 27, a sprinkling port 23d is opened on the reduction gear chamber 19, a gear 25 of the reduction gear 22 is arranged between an opening part 23c facing the inside of the reduction gear chamber 19 of the water channel 27 and the sprinkling port 23d, and water ejected from the water ejection port 20a is made to sequentially pass the inside of the hydraulic turbine chamber 18, the water channel 27, the inside of the reduction gear chamber 19 and the sprinkling port 23d.</p> |
