<p>A method and device for the adjustment of the temperature of a rotating body easily. Fluid passages (74, 76) co-rotating with a rotating main body (10) are provided outside the rotating main body (10). Rotary shafts (30a, 30b) are fixed to both ends of the rotating main body (10). Inside the rotary shafts (30a, 30b), there are formed introduction inside passageways (66a, 68a) and discharge inside passageways (66b, 68b) both communicating with the fluid passages (74, 76). The rotary shafts (30a, 30b) are supported rotatably by support members (34a, 34b) through bearings (32a, 32b). A fluid for temperature adjustment is introduced from the position of the support member (34a) into the fluid passages (74, 76) through the introduction inside passageways (66a, 68a) of the rotary shaft (30a) and is discharged from the fluid passages (74, 76) through the discharge inside passageways (66b, 68b) of the rotary shaft (30b). Thus, the temperature of the rotating body (10) can be adjusted.</p> |
