齿轮是机床中最主要零件之一，它的制造也是机床制造中最复杂的问题；因此齿轮噪音的产生与各方面都有关系。正如局顾问专家克拉沙夫柴夫同志所说：“想很快解决齿轮噪音问题是不可能的。过去在苏联也发生过像您们目前所发现的齿轮噪音问题。只有建立起试验的制度，派专人负责这方面的工作；并且学习兄弟厂有关这方面改进的经验，才能逐步改进齿轮噪音”。因此；我们应该踏踏实实地顺着专家所指出的道路去努力。 为此，局刊特从本期起展开一个［改善齿轮质量，降低齿轮噪音；提高机床质量］的广泛讨论，今将大连机床厂一年中在齿轮噪音方面所获得的经验介绍于下，作为讨论的开始。希望各有关单位对这方面有修养的学者、工程技术人员、广泛并及时地投入这个讨论的浪潮中，集中大家的智慧，使改善齿轮的方法在大家所提出的宝贵意见中得到进一步的明确。因为我们知道宝贵的意见往往就是实践中所获得的点滴经验，如果能把许多点滴的经验得到系统地编纂与提高，并通过本刊及时得到交流，那未齿轮质量问题就可能在造次热烈讨论中获得改善。 Gear is one of the most important parts of a machine tool, and its manufacture is also one of the most complex problems in machine tool manufacture; hence the generation of gear noise is related in all aspects. As Comrade Krasoudovici, a consultant of the bureau, said: “It is impossible to solve the problem of gear noise very quickly. In the past there have also been gear noise problems like those you have discovered so far in the Soviet Union. Only by establishing an experimental system, Send someone to take charge of the work in this area, and learn about the improvement experience from brother factory in this respect, so as to gradually improve the gear noise. ” Therefore, we should work steadily along the path indicated by the experts. To this end, the Bureau of special issue starting from this issue launched a [to improve gear quality, reduce gear noise; improve machine tool quality] of the extensive discussion, the Dalian Machine Tool Plant a year in gear noise experience gained in the following, as The beginning of the discussion. We hope that relevant departments will focus their wisdom on this broad and timely wave of scholars, engineers and technicians who are well-versed in this regard and make the method of improving the gears further clarified in the valuable opinions of all of you. Because we know that precious opinions are often the experience gained in practice. If we can systematically compile and improve many experiences and communicate them in time through our publications, the problem of gear quality may be heatedly discussed. In the improvement.
