在我厂自行设计制造的1000T压力机上采用了滚动导轨,该压力机的立柱为钢板焊接的箱形结构。当活动梁导轨相对于立柱导轨上下移动时,滚柱即在两导轨间滚动,从而起到导向作用。该导轨具有以下优点: 1.较低的起始摩擦系数,可使摩擦阻力显著降低。一般说来,大型压力机的导轨多数是铅垂方向布置的,而且各个导轨间的距离比较远,因而对偏载比较敏感。如采用滑动导轨,则在导轨载荷大的局部的油膜易被破坏,从而增加了摩擦阻力(摩擦系数可达0.1～0.5)。而采用滚动导轨,摩擦系数仅在0.01
In our factory 1000T press designed and manufactured using a rolling guide, the column for the press welded steel box-shaped structure. When the movable beam rails move up and down relative to the column rails, the rollers roll between the two rails to play a guiding role. The rail has the following advantages: 1. Lower initial coefficient of friction, can significantly reduce the frictional resistance. In general, the majority of the large press rail is arranged vertically, and the distance between the various rails, and therefore more sensitive to partial load. Such as the use of sliding rail, the guide rail load large local oil film easily destroyed, thereby increasing the frictional resistance (friction coefficient up to 0.1 ~ 0.5). The use of rolling guide, the friction coefficient of only 0.01
