多数齿轮在使用中都需要施加适当的载荷,使其发生弯曲,产生压缩应力。要想使齿轮材料达到这些性能要求,就要对其进行热处理,随着热过程的进行,将产生变形。为了控制齿轮的变形并获得稳定的尺寸公差,齿轮在淬火期间受到约束。这种形式的夹持淬火便是齿轮淬火压床的基础。本文就此问题作了阐述。 Most gears in the use of the need to apply the appropriate load, making it bent, resulting in compressive stress. To achieve these performance requirements gear materials, it is necessary to heat treatment, with the thermal process, will produce deformation. In order to control gear deformation and obtain a stable dimensional tolerance, the gear is constrained during quenching. This form of clamping quenching is the basis for gear quenching presses. This article elaborates on this issue.
