摘　　要：通过控制同步器齿轮等温正火的控制和改进加压前的渗碳空气冷却钳位模式,同步器齿座压淬的变形控制能力得到了有效的提高。由于淬火后的变形较大,特别是圆度超差是最严重的。为了解决真正的圆度问题,需要使用压淬处理,大量的人力资源和材料资源被浪费。文章分析了产生变形的原因,从原材料、热处理工序和设备情况等方面进行有效分析。By controlling the isothermal normalizing of the synchronizer gear and improving the carburizing air cooling clamping mode before pressurization, the deformation control ability of the synchronizer gear holder during press hardening has been effectively improved. Because of the large deformation after quenching, especially the roundness out of tolerance is the most serious. In order to solve the real roundness problem, it is necessary to use press hardening, and a lot of human and material resources are wasted. This paper analyzes the causes of deformation, and makes effective analysis from raw materials, heat treatment process and equipment.
