齿轮锻坯的质量控制

Quality Control of Forged Gear Blanks

齿轮锻坯的质量不良会使随后的机加工困难,恶化齿轮的热处理质量,降低齿轮精度和使用性能。影响齿轮锻坯质量的因素是多方面的,如原材料质量、预备热处理和锻造工艺。采用排列图可以找出导致齿轮锻坯不合格的主要原因,从而采取相应的预防措施。

Poor quality of forged gear blanks will result in the difficulty of machining , affect the quality of heat-treated gears and decrease the precision and operational peformance of gears . There are quite a few factors which will affect the quality of forged gear blanks, such as quality of raw material, conditioning heat treatment and forging process. An arrangement diagram may be employed to discover the essential reason which leads to the poor quality of forged gear blanks and correspondingly preventatives may be taken
