作者根据近年来在降低齿轮箱噪声方面的工作和实践,参阅国内外有关文献,总结了影响机械传动噪声中的各种因素——重点是有关齿轮噪声的影响原因和一般规律。同时还分析了齿轮箱噪声的传导及幅射,简明地介绍了在实践中行之有效的主噪声源探查方法。最后,还详尽地提出了控制齿轮箱噪声的有关设计和工艺措施,列举了一些生产工厂降低噪声的实例。 According to the work and practice of reducing gearbox noise in recent years, the author refers to relevant literatures at home and abroad and summarizes various factors that affect mechanical transmission noise - the focus is on the causes and general rules of gear noise. At the same time, the transmission and radiation of the gearbox noise are also analyzed, and the effective method of detecting the main noise source in practice is briefly introduced. Finally, the design and process measures to control the noise of the gearbox are put forward in detail. Some examples of how to reduce the noise in the production plant are listed.
