挠性弹簧托辊是近几年国外广泛用于带式输送机的一种新型托辊。它由一个粗弹簧代替传统的三个为一组的槽型托辊。弹簧的两端各装有一盘单列向心短圆柱滚子轴承和一盘单列圆锥滚子轴承组成转动副;轴承安装在两端带有圆柱形耳子的球墨铸铁轴承座内。轴承座外侧装有黄油咀,轴承座内侧装有两道密封的透盖,这样构成一套挠 Flexible spring idler is widely used in foreign countries in recent years, a new belt conveyor idler. It consists of a thick spring instead of the traditional three as a group of grooved roller. Each end of the spring is equipped with a single row of radial cylindrical roller bearings and a single row of tapered roller bearings to form a rotating pair; the bearings are mounted on both ends of the cylindrical lug ductile iron bearing. A grease nipple is mounted on the outside of the housing, and two sealed through caps are provided on the inside of the housing, thus forming a set of flexible
