托辊的基本简介及分类

Basic introduction and classification of idlers

托辊的作用是支撑输送带和物料重量。托辊运转必须灵活可靠。减少输送带同托辊的摩擦力，对占输送机总成本25%以上的输送带的寿命起着关键作用型线  流水槽模具 景观石 检查井钢模具 保定通风管道 重庆窗帘 隔离墩模具 保定保洁公司。虽然托辊在带式输送机中是一个较小部件，结构并不复杂，但制造出高质量的托辊并非易事。

The role of the roller is to support the conveyor belt and material weight. The roller must be flexible and reliable. Reducing the friction between the conveyor belt and the roller plays a key role in the service life of the conveyor belt which accounts for more than 25% of the total cost of the conveyor. Although the idler is a small part of belt conveyor and its structure is not complicated, it is not easy to produce high-quality idler.

判断托辊好坏的标准有以下几条:托辊径向跳动量;托辊灵活度;轴向窜动量。

There are several criteria to judge the quality of idler: radial runout of idler; flexibility of idler; axial displacement.
