精密摩擦付是每种具有转动或滑动动作的精密机械的关键零件。从使用的角度来看,它的质量直接决定着整机的技术指标。制造经久耐用的精密摩擦付对于提高整机性能有二重意义:其一,长寿命摩擦付自然延长整机的使用寿命,减少零件耗损与整机维修时间,有很大的经济意义;其二,对于特定的使用场合,机器一经启动,在相当长的时间内不可停机,长寿命精密摩擦付就更加显示出其重要性了。从制造的角度来看,精密摩擦付允许公差很小,只有
Precision Rubbing is a key part of every type of precision machine that has a rotating or sliding motion. From the use point of view, its quality directly determines the technical indicators of the whole machine. Manufacturing durable durable friction pay to improve the performance of the machine have two meanings: First, the long-life friction to pay the natural extension of the service life of the machine to reduce parts wear and repair time machine, with great economic significance; the second , For a particular use of the occasion, the machine is started, in a very long period of time can not be shut down, long-life precision friction pay even more shows its importance. From a manufacturing point of view, precision friction allowable tolerances are small, only
