Abstract

PURPOSE: To shorten the number of man-hours concerned and the number of days, by facilitating repair work in the case when a shaft is damaged, etc. by forming the outer diameters of portions fitting to each portion in the shaft in multistage shapes so that the outer diameters successively become smaller toward the other direction from the one direction of the axial direction.
CONSTITUTION: The relationship of each fitting diameter dimension ϕ4, ϕ1, ϕ5 of a commutator 6 provided with a clamping fitting 10 doubling as core push, a rotor core 2 and a core keep 4 to a shaft 1 is set to ϕ4<ϕ1<ϕ5. Thus, this device is assembled in such a manner that the core keep 4 is shrinkage-fitted to the shaft 1 from the right direction, the rotor core 2 is stacked, the core 2 is pressurized in order to produce core surface pressure, the commutator 6 equipped with the clamping fitting 10 is similarly shrinkage-fitted from the right, an armature coil 3 is wound in a slot of the rotor core 2 according to a conventional method and a lead wire of the coil 3 is connected to a riser portion of a commutator piece 7. Consequently, the assembly work of the commutator is simplified, and the number of man-hours concerned work and the number of days can sharply be shortened.
