Brief introduction of conveyor roller

输送带，又称运输带，是用于皮带输送带中起承载和运送物料作用的橡胶与纤维、金属复合制品，或者是塑料和织物复合的制品。输送带广泛应用于水泥、焦化、冶金、化工、钢铁等行业中输送距离较短、输送量较小的场合。

The conveyer belt, also known as the transport belt, is a rubber, fiber, metal compound used for carrying and transporting materials in the belt conveyer belt, or a compound of plastic and fabric. Conveyor belts are widely used in cement, coking, metallurgy, chemical industry, steel and other industries, and the transportation distance is short and the transportation volume is small.

输送带，皮带输送机在农业、工矿企业和交通运输业中广泛用于输送各种固体块状和粉料状物料或成件物品，输送带能连续化、高效率、大倾角运输，输送带操作安全，输送带使用简便，维修容易，运费低廉，并能缩短运输距离， 降低工程造价，节省人力物力。

Conveyer belt, belt conveyer is widely used in agriculture, industrial and mining enterprises and transportation and transportation industry to transport a variety of solid and powder material or parts. The conveyor belt can be used continuously, high efficiency and big angle transportation. The conveyor belt is safe to operate, the conveyor belt is easy to use, the maintenance is easy, the freight is cheap, and the transportation distance can be shortened. In order to reduce the cost of the project and save the manpower and material resources.

输送带系列产品有普通棉帆布输送带、尼龙（NN）输送带、聚酯（EP）带、大倾角(波状挡边)输送带、裙边隔板输送带、环形输送带、花纹输送带{由于运送物料不同和输送倾角大小不同，要求花纹形状和高度也不同。或根据用户要求设计,PVC或者PVG整芯阻燃带等；并能提供各种特殊性能的输送带（一般阻燃输送带、耐热输送带、耐灼烧输送带、高耐磨输送带、耐酸输送带、耐碱输送带、耐寒输送带、耐油输送带、耐高温输送带、高强力输送带及食品输送带）。

A series of conveyer belts include ordinary cotton canvas conveyor belt, nylon (NN) conveyor belt, polyester (EP) belt, large dip angle (wavy edge) conveyor belt, skirt belt conveyor belt, ring conveyor belt, pattern conveyer belt {request pattern shape and height vary with the different delivery material and the size of conveying angle. Or designed according to the user's requirements, PVC or PVG whole core flame retardant belt, and can provide various special properties of conveyor belts (general flame retardant conveyor belt, heat-resistant conveyor belt, burning conveyor belt, high wear resistant conveyor belt, acid resistant conveyer belt, alkali resistant belt, cold resistant conveyer belt, oil resistant conveyor belt, high temperature resistant conveyor belt, high strength transportation. Belt and food conveyor belt.

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。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 idlers is to support the weight of conveyor belts and materials. The operation of the roller must be flexible and reliable. Reducing the friction force between the conveyor belt and the idler will play a key role in the life span of the conveyor belt which accounts for more than 25% of the total cost of the conveyor. Although the roller is a small component in the belt conveyor, the structure is not complicated, but it is not easy to make a 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。按材质分为橡胶托辊、陶瓷托辊、尼龙托辊及绝缘托辊。

There are several criteria for judging whether the idler is good or bad: the radial runout of the idler, the dexterity of the idler, and the axial momentum. According to the material, it is divided into rubber idler, ceramic idler, nylon roller and insulating idler.
