    • An apparatus for heating a workpiece, particularly a roller bearing, having low power consumption, rapid heating and low weight, includes a truncated conical contact surface for horizontal workpiece bearing, a single-layer solenoid coil underneath the contact surface, following the contact surface shape relative to its covered surface and gradient, resulting in magnetic lines of force concentrated in an internal workpiece area and a driver resonant circuit producing an alternating magnetic field in the solenoid coil. The workpiece is inductively heated quickly without requiring pushing onto a magnet yoke, because of its horizontal bearing. The planar configuration of the solenoid coil, following the contact surface shape, causes operation of the driver resonant circuit at high frequency, resulting in low power consumption. The profile of lines of force causes the magnetic field to directly enter areas to be heated on an upper workpiece surface, ensuring homogeneous workpiece heating.
    • 一种用于加热具有低功耗,快速加热和低重量的工件,特别是滚子轴承的装置,包括用于水平工件轴承的截锥形接触表面,接触表面下方的单层电磁线圈,接触表面形状 相对于其覆盖的表面和梯度,导致集中在内部工件区域中的磁力线和在螺线管线圈中产生交变磁场的驱动器谐振电路。 由于其水平轴承,工件被快速感应加热而不需要推到磁轭上。 螺线管线圈的平面构造,在接触面形状之后,使驱动器谐振电路工作在高频,导致低功耗。 力线的轮廓使磁场直接进入上工件表面加热的区域,确保均匀的工件加热。
