Abstract

PURPOSE:To enable the cooling of bearings without using coolant by providing an inner tube formed with a work liquid circulating passage in an enclosed hollow part formed in a part of a rotational shaft, thereby radiating heat through the liquid. CONSTITUTION:An enclosed hollow part 5 formed to coincide at the center of the longitudinal axis of a shaft 2 with the center of the shaft 2 along the longitudinally axial direction of the shaft 2 is disposed at one end side 5a at the part of a bearing 1 as a heat generation source and is exposed at the other end side 5b with a water channel 6. An inner tube 7 is provided coaxially with the hollow part 5 in the hollow part 5, a spiral member 8 of the height approximately contacted with the inner wall surface of the hollow part 5 is provided at the outer periphery of the tube 7, and work liquid of suitable quantity selected adequately in response to the using temperature and place such as water, Freon, etc. is sealed in the hollow part 5. The heat generated from the bearings 1 is transferred to the work liquid therein by means of transfer and convection, is circulated to the water in the water channel 6 by means of the transfer and convection again.
