齿轮在高频感应加热淬火时,由于热应力和组织应力的作用,再加上齿轮形状和尺寸的影响,不可避免地会使齿轮的各部位发生程度不同的变形。这些变形必须在淬火后用不同的方法进行校正加以消除。否则,将降低齿轮的精度和寿命,而影响整台机床的质量。因此,控制齿轮在高频淬火时的变 When gears are heated and quenched by high-frequency induction, due to the effects of thermal stress and tissue stress, together with the influence of the shape and size of the gear, inevitably, various degrees of distortion of gears occur. These deformations must be corrected by a different method after quenching. Otherwise, the accuracy and life of the gear will be reduced, which will affect the quality of the entire machine. Therefore, the control gear changes in high frequency quenching
