Abstract

PURPOSE:To improve the productivity of assmebling operation by fixing a rotary supporting body to a supporting member after stepping a rotating shaft where the supporting member is fixed in a bearing fitted to a housing and thus forming the rotating shaft part in such a way that only the rotating shaft part is assembled independently, and then confirming the precision in said state. CONSTITUTION:On the rotary drum side of a rotating shaft 6, a supporting member 19 is fixed by a pressing-in method, etc., the rotating shaft 6 is stepped in bearings 7a and 7b fitted to a housing 22, and a lower supporting body 10 is fixed on the rotating shaft 6 with a setscrew 11. Then, a rotary supporting body 4 is only fixed to the supporting member 19 to check the run-out of the fitting surface of the rotary drum 3 of the rotary supporting body 4, confirming precision. Then, the internal diameter D1 of a rotation-side rotary transformer 9a and part D2 of the internal diameter of the rotary supporting body 4 are made greater than the external diameter (d) of the supporting member 19, and the rotation-side rotary transformer 9a is boned and fixed to the rotary supporting body 4.
