平衡技术在汽车工业中的应用

Application of Balance Technology to Automobile Industry

对于旋转机械而言,由于质量分布不均匀而产生的离心惯性力是产生机械振动的重要原因,这一点已成为广大技术人员的共识。机械振动会影响产品性能的提高、加速轴承磨损、降低使用寿命、产生噪声污染,在各类机械制造业中越来越引起广泛重视和密切关注。汽车工业是涉及旋转零部件数量多、类别繁杂的一个制造行业,尤其是高级轿车对乘坐舒适性、平稳性要求的提高,对平衡性能相应提出了更加严格的要求。同时,汽车工业的发展带动了平衡技术的进步,平衡技术的进步又促进了汽车性能的提高。本文阐述了汽车制造中需要平衡的转子类别以及对平衡性能的需求,列举了主要几大类转子的平衡及其平衡设备,为汽车制造业、维修服务业的技术人员以及各大、专院校汽车系的师生们提供了有关平衡的知识和信息。

For the rotational machines, it is a very important reason for generating mechanical vi- bration that the quality non - equality brings the centrifugal inertial force. It is well known for many technique personnel about this. The mechanical vibration could affect increasing for some product performances, speed up wearing for bearings, debase use life, and bring noise pollution. It＇ s been paid more and more attentions in many kinds of mechanism manufacturing. The automobile industry is one of manufactures, which deal with the most number of rotation- al ports and sorts. Specially, increasing the riding requirement of comfort and stability for luxury cars, the more strict requests can be made opments of automobile industry also bring for balance performance. At the same time, the devel- along the balance technology advancement, thus pro- motes increasing automobile performance. This thesis expatiates in detail with the sorts of balancing rotors, and the requirements of bal- ancing performance, which needed in automobile manufacture. Many kinds of balancing rotors and equipments are mostly mentioned in it. And it supplies some knowledge and information linked with balance for the technology personnel in automobile manufacture and maintaining service departments, as well for teachers and students in automobile department of colleges and universities.
