| 托辊在材质上分为钢质和塑料托辊两种。托辊的轴承座有铸铁的和钢板冲压的和酚醛塑料等三种。托辊的密封有钢和塑料之分。它们的密封都是内部填充润滑脂。托辊的好坏直接影响带式输送机的电能消耗和皮带的寿命。因此防尘密封可靠，润滑良好是重要使用标准。 The supporting rollers are divided into steel and plastic supporting rollers in material. There are three kinds of bearing seats for idlers: cast iron, steel stamped and phenolic plastics. The seal of idler is divided into steel and plastic. Their seals are filled with grease. The quality of idler directly affects the power consumption of belt conveyor and the life of belt. Therefore, reliable dust-proof seal and good lubrication are important standards for use. |
