托辊是带式输送机的重要部件
托辊是带式输送机的重要部件,种类多,数量大。作用是支承皮带,减少皮带运行阻力,并使皮带的垂直度不超过一定限度以保证皮带平稳地运行。
Idler is an important part of belt conveyor, which has many kinds and large quantity. The function is to support the belt, reduce the running resistance of the belt, and make the perpendicularity of the belt not exceed a certain limit, so as to ensure the smooth operation of the belt.
托辊按其用途分类为调心托辊、缓冲托辊、槽形托辊、平行托辊。调心托辊的作用是纠正带式输送机的跑偏,通常输送机的重载段上安装回转式槽形调心托辊,空载段上安装平行调心托辊。缓冲托辊是根据实际情况应用于机尾架上的,受料时,可以降低物料对皮带的冲击,有利于沿长皮带的使用寿命。槽形托辊一般由两个侧托辊和一个平托辊组成,槽角度一般为30度,对于可拆卸式的带式输送机,槽形托辊的三个托辊互相铰接在一起,故称铰接托辊。平行托辊一般为一个长辊,它安装在承受压力的下端故称下托辊。
The idlers are classified into centering idler, buffer idler, grooved idler and parallel idler. The function of self-aligning idler is to correct the deviation of belt conveyor. Generally, the rotary groove type self-aligning idler is installed on the heavy-duty section of the conveyor, and the parallel self-aligning idler is installed on the no-load section of the conveyor. The buffer idler is applied to the tail frame according to the actual situation. When receiving the material, it can reduce the impact of the material on the belt, which is beneficial to the service life of the belt along the length. The groove idler is generally composed of two side idlers and one flat idler, and the groove angle is generally 30 degrees. For the removable belt conveyor, the three idlers of the trough idler are hinged together, so they are called articulated idler. The parallel idler is generally a long roller, which is installed at the lower end of the pressure, so it is called the lower idler.
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。
The roller can be divided into steel roller and plastic roller. There are three kinds of roller bearing seat, such as cast iron, steel plate stamping and phenolic plastic.
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 seal of idler can be divided into steel and plastic. Their seals are filled with grease inside. The quality of idler directly affects the power consumption and belt life of belt conveyor. Therefore, reliable dust seal and good lubrication are important standards for use.
托辊占了一台带式输送机总成本的35%流水槽钢模具 不锈钢铸件 扭王字块模具 井盖钢模具 标志桩模具 调匝式消弧线圈 风冷控制柜 烤漆龙骨 ,是带式输送机的重要组成部件,主要肩负着承载输送物料的作用,在皮带机的运输过程中承受70%以上的阻力,是皮带机中用量最大、更换频率最高的零部件,因此托辊的使用寿命在整部皮带机中十分重要。
The carrier roller accounts for 35% of the total cost of a belt conveyor. It is an important component of the belt conveyor. It mainly bears the role of conveying materials. It bears more than 70% resistance in the transportation process of the belt conveyor. It is the parts with the largest consumption and the highest replacement frequency in the belt conveyor. Therefore, the service life of the idler is very important in the whole belt conveyor.
