Title:
ROTOR FOR ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS61102141
Kind Code:
A
Abstract:
PURPOSE:To reduce the bending degree of a rotary shaft, by dividing a rotor clamp. CONSTITUTION:A rotor core 5 is clamped on the both sides by a rotor clamp 4, and the rotor clamp 6 is retained by a key 7 fixed on a rotary shaft 4. The rotor clamp 4 is divided into 6A and 6B. The divided surface is spherical, and the rotor clamp 6A, 6B can incline relatively to an axis. The rotor clamp 6B is thinner than the rotor clamp 6A, and in case that the rotor core 5 is deformed, the rotor clamp 6B and the rotor core 5 separate from each other not to interfere together. Therefore, the shaft can be prevented from bending.
