前言目前中高速柴油机滑动轴承广泛采用薄壁轴瓦结构。薄壁轴瓦依靠适当的过盈量固定在轴承座孔中。实践表明,薄壁轴瓦的过盈量太大或不足都会导致轴承的早期损坏,而过盈量的上限值受到轴瓦应力的限制。所以轴瓦应力的计算与试验一直引起内燃机工作者的重视。 Preface At present, high-speed diesel engine sliding bearings are widely used in thin-walled bush structure. Thin-walled bushings rely on the appropriate amount of interference fixed in the bearing housing hole. Practice shows that thin-walled bearing too much or too much interference will lead to early bearing damage, while the upper limit of interference by bearing stress. Therefore, the calculation and testing of bearing stress has been caused by the concern of internal combustion engine workers.
