段付き軸加熱用コイル。 In a coil that moves and heats a stepped shaft, in which step portions of small diameter and large diameter are sequentially formed following the shaft portion, from the step portion to the shaft portion while rotating the shaft, the heating conductor of the coil is connected to the arcuate portion ca and the arcuate portion. It is a single winding divided into a portion cb, and each of the arcuate portions ca and cb has ca<< in relation to the arc length and conductor cross-sectional area.
While maintaining cb, the arcuate part ca becomes the arcuate part c
b with a predetermined step and shift toward the rear in the direction of movement, and is formed so that its inner circumferential tip points toward the shoulder corner of the large diameter step, and the arcuate portion cb has a wide width. A protrusion is formed on the rear side in the direction of movement of the inner circumferential wall, the tip of which is oriented toward the shoulder corner of the small diameter step,
The magnetic flux addition amounts φa and φb generated from the protrusions of the arcuate portions ca and the arcuate portions cb and added to the opposing portions are set to be approximately equal in relation to the length of the arc and the cross-sectional area of the conductor. Stepped shaft heating coil.
