摘要
研究了直齿圆柱齿轮的冷精锻过程 ,分析了分流孔形状、成形工艺等因素对齿轮成形的影响。结果显示 ,选择适当的分流孔尺寸可以降低成形载荷 ,但作用不很明显。采用凹模运动方式可调的齿轮精锻法可以同时兼顾齿轮上、下角部的成形 ,利于齿轮的填充 。
The cold precision forging of spur gears has been researched, and the effects of relief-hole shape and forging process on the spur gears forming has been analyzed. The results present that the forging load decreases when a suitability diameter of relief-hole is chosen, but the function is not obvious. The spur gears precision forging method with an adjustable movement of concave mould can benefit both the top and the bottom corners forming of the spur gears, full fill the tooth cavity, and decrease the forging load.
