| 发明名称 | Device for heating and method for heating | ||
| 摘要 | A method and device for heating or hardening at least an axial segment of a rotationally-symmetric surface of a work piece includes rotating the work piece about its rotational axis and moving a peripheral portion of an inductor along a longitudinal profile of the axial segment of the rotating work piece with a constant spacing between the peripheral portion and the axial segment. At least a portion of the movement of the peripheral portion is composed of a first vector component in the direction of the rotational axis and a second component extending perpendicularly to the first vector component. The peripheral portion has a length in the rotational axis direction that is less the length of the axial segment in the rotational axis direction. | ||

| 主权项 | 1. A heating device comprising: an inductor having a movable peripheral portion configured to heat at least an axial segment of a rotationally-symmetric surface of a work piece while the work piece is rotating about a work piece rotational axis, wherein the peripheral portion has an axial length in the direction of the work piece rotational axis that is less than the length of the axial segment in the work piece rotational axis direction, and a controller configured to move the inductor at an acute angle relative to the work piece rotational axis while maintaining a defined spacing between the inductor and the work piece. | ||
