近年来,随着工程机械及风电行业的振兴,大型回转支承及轴齿轮得到了快速的发展。但该类产品普遍存在的质量问题是:齿形的淬火质量不能达到设计要求,造成回转支承或轴齿轮的齿形在工作过程中磨损不均匀,降低了产品的使用寿命。经分析,问题产生的主要原因是:由于此类零件齿数多、模数大,每次进行分度时因机械或其他方面的原因常造成分度不准确,导致在淬火过程中齿形与感应器的间隙不能始终保证一致,使其在
In recent years, with the revitalization of construction machinery and wind power industry, large slewing bearings and shaft gears have been rapidly developed. However, the prevalence of such products is the quality of the problem: the quality of the tooth-shaped quenching can not meet the design requirements, resulting in slewing ring or gear tooth profile in the work of uneven wear and reduce the service life of the product. After analysis, the main reason for the problem is: due to the number of such teeth, the module is large, each indexing due to mechanical or other reasons often cause sub-indexing is not accurate, resulting in the process of quenching tooth and induction The gap between the devices can not always be the same
