大模数齿轮进行热处理强化,是提高齿轮传动工作寿命和降低重量的有效方法。但随着硬度的提高,材料的加工性变坏,使加工用量降低和刀具磨损加剧,从而导致加工成本的提高(见图1)。采用新刀具材料(如P9M4K8和P6M5K5高速钢)虽可维持原加工用量和刀 Large modulus gear heat treatment to strengthen, is to improve the working life of gear transmission and reduce the weight of the effective method. However, as the hardness increases, the workability of the material deteriorates, resulting in lower processing costs and increased tool wear, resulting in higher processing costs (see Figure 1). The use of new tool materials (such as P9M4K8 and P6M5K5 high-speed steel) Although the original processing capacity can be maintained and the knife
