HOUSING STRUCTURE OF ROTARY TRANSFORMER

摘要

PROBLEM TO BE SOLVED: To raise the housing efficiency of rotary transformers. SOLUTION: A unit on the rotor side or stator side of a rotary transformer has cores 110 and post-attached components 112 in a state that the components 112 are extendedly provided in the directions of the outer diameters of the cores 110. A tabular body 114 has installation parts 116 and 118 for installing the cores 110. The installation parts 116 and 118 respectively have supporting surfaces 116A and 118A for supporting the cores 110 and protuberances 116B and 118B for installation, which are fitted into through holes 110A formed in the cores 110. The installation part 116 on one side of the installation parts 116 and 118 is formed on the flat surface of the supporting surface 116A and the other installation part 118 is formed in a recessed part 118C. Therefore, the adjacent cores 110 are respectively installed and held on the installation parts 116 and 118 with a step between the cores 110, the rotary transformers are arranged in a state that the post-attached components 112 of each rotary transformer are overlapped with each other and the housing efficiency of the rotary transformers can be enhanced.
