在轻纺、化工、矿山和其它机械中,常常会碰到一些转速较高的粗糙圆筒体,它们本身动、静都不平衡。但是,为使机器平稳地工作,却要求这些粗糙的圆筒体动平衡。然而,目前很多企业都没有价格昂贵的动平衡试验机,面对这些粗糙的圆筒体的动平衡不是束手无策,便是对它们只做简单的静平衡试验。其结果常常使装有这些圆筒的机器振动不止,严重地影响了机器的正常使用和寿命。 最近,我们厂在生产粗纱头机的过程中亦遇到了类似的问题。粗纱头机的关键部件——“锡林”是个粗糙的铸造圆筒,它仅加工了外表面及端面,
In the textile, chemical, mining and other machinery, often encounter some of the higher speed rough cylindrical body, their own dynamic and static imbalance. However, to make the machine work smoothly, these rough cylinders are required to be dynamically balanced. However, at present, many enterprises do not have expensive balancing test machines. In the face of the rough balance of these rough cylindrical bodies, they are not at their fingertips, and only simple static balance tests are conducted on them. As a result, machines equipped with these cylinders often vibrate more than once, seriously affecting the normal use and life of the machine. Recently, we encountered similar problems in the production of roving machines. The key part of the roving machine - “cylinder” is a rough casting cylinder, which only machined the outer surface and the end surface,
