前言 在旋转机械的振动和噪声源中,结构中的轴承是其基本来源之一。轴承的振动和噪声问题,牵涉着很多方面,具有许多复杂的因素。 工程技术人员们多年的研究已表明,在影响单个滚动轴承振动的诸多因素中,如滚动体和内、外套圈沟道的圆度、波纹度、光洁度及轴承的径向游隙等,其中波纹度影响为最大,而尤以滚动体的波纹度影响最甚。很多厂家从工艺上做了大量努力来降低各另件的波纹度,并取得了显著的效果。 Foreword In the vibration and noise sources of rotating machinery, the bearing in the structure is one of its basic sources. Bearing vibration and noise problems, involving many aspects, with many complex factors. Years of engineering and technical personnel studies have shown that in a variety of factors that affect the vibration of a single rolling bearing, such as the circularity, waviness, smoothness and bearing radial clearance of the rolling element and the inner and outer raceways, etc., of which waviness The influence is the biggest, but especially the rolling body’s waviness influence most. Many manufacturers have done a lot of work from the craft to reduce the waviness of each piece, and achieved remarkable results.
