Method for pre-mounting the electrical swivel type armature magnetic drive as well as turning the armature type magnetic drive for switching the machine

摘要

(57) Abstract This invention, the electric change machine, for example regards the revolving armature type magnetic Drive device for the contactor. As for the topic which it should solve, as a thing and the compact structural group which overcome the allowance problem which it is related to the iron-made part there is the installation before the automatic operation. Because of this, yoke 28, magnetic core 30, electrode 32 and revolving armature 26, oneself being adjusted power by the fastening spring 68 which is loaded, and it is containment breaking off impossibly inside coil shell 34. As for coil shell 34, casing part 12; The formation department 76 which generates the opposite pressure for 14; 82; Having possessed 83, said formation department, revolving armature type magnetic Drive device 16 the distance restriction A; Adjusting inside the casing in regard to B, it has registered.
