胶带跑偏原因及纠正措施一、导致皮带跑偏的主要因素1、胶带的结构、类型和工作条件（机架地基出现不均匀沉降、风霜雨雪的影响）2、由驱动和张紧装置所传递的功率和张力大小3、胶带接头对准程度4、非承载面存在灰尘和水5、加载方向和落料点是否对中二、各种跑偏原因及对策措施1、所有胶带在机架的某一部位向一侧跑偏。
One or more idlers immediately preceding trouble point not at right angles to the direction of belt travel.一个或多个拖辊在前述故障点上延胶带运动方向角度不正Advance, in the direction of belt travel, the end of the idlerto which the belt has shifted. Square idlers.首先延着胶带运动方向，对胶带跑偏的哪一侧托辊进行方形校正Conveyor frame or structure crooked.皮带机架弯曲Stretch string along edge to determine extent and makecorrection.沿机架边缘拉一条直线来判断弯曲程度，然后进行校正。
One or more idler stands not centered under belt.一个或多个拖辊不正Center them. Same as above.校正拖辊Sticking idlers.拖辊粘滞Clean and lubricate.清理和润滑拖辊Belt runs off terminal pulley.Check terminal pulley assignment. Check alignments ofidlers approaching terminal pulley.Build up of material on idlers.物料粘结在拖辊表面Clean them. Install cleaning device.清洗掉物料安装清理设备Structure not level and belt tends to shift to low side.机架不平导致皮带向较低一侧偏移Level structure.调平机架2、胶带的某一段沿整机向一侧跑偏。
Belt not joined squarely.皮带接头不正Square ends/resplice.调正接头Bowed belt.皮带弯卷Tension it or replace.张紧皮带或更换3、胶带在较长距离一段机架位置向一侧跑偏。
Load being placed on belt off-center.落料点偏离皮带中心Adjust chute and loading conditions so as to place load inthe center of belt.调整溜槽或落料点使物料落在皮带中心Conveyor frame or structure crooked.皮带机架弯曲Straighten it.调直机架4、胶带无规律跑偏。
Belt too stiff to train.皮带太硬无法调整Use self-aligning idlers. Increase tension/conforms tocrowns. Use more flexible belt on replacement.采用自调偏拖辊增大牵引力用柔韧性好的皮带替换Tilt troughing idlers forward, but not over 2 degrees. Use moretroughable belt.槽形拖辊向前翘起，但不超过2度需用更多的槽形拖辊Combination of causes listed under Paragraphs 2 and 3.Correct loading first. Other causes can then be identified andcorrected.首先调整落料点，然后再考虑其它办法三、整机纠偏顺序The basic, and primary rule of tracking a conveyor belt is simply "THE BELT MOVES TOWARD THAT END OF THE ROLL IT CONTACTS FIRST."检查胶带首要的、基本的原则是“胶带朝与托辊最先接触的一端运动”The NORMAL SEQUENCE of training is to start with the return run, working toward the tail pulley; following with top run in the direction of belt travel. Start with the belt empty. After tracking is completed, run the belt with a full load and re-check tracking.检查胶带的正常顺序是先从下皮带开始，向机尾处检查；随后延皮带运行方向检查上皮带。
先空载检查，之后再带载检查。
TRACKING ADJUSTMENT is done while the belt is running and should be spread over some length of the conveyor preceding the region of trouble. Permit the belt to run for several minutes and at least three full belt revolutions after idler has been adjusted to determine if additional adjustment is required. If the belt has over-corrected, it should be restored by moving back the same idler, and not be shifting additional idlers or rollers.应在皮带运行时对前述故障区域进行调整，在拖辊调整后如还需进行额外调整，皮带应先运行至少三圈。
如果皮带调整过头，需要及时对所调过的拖辊进行恢复，不能调整其它拖辊或辊筒。
enlarge#1 Conveyor troughing idlers are offered in a wide variety of styles. Troughing angles include 20°, 35°, & 45°. The stands are primarily two (2) types and vary with each manufacturer.皮带槽形托辊有多种类型。
槽角有20°、35°和45°。
常用的主要有两种，随制造商不同而变化1. "Straight" (over 90°) This stand has no tilt, and is designed for the conveyor belts to run in both directions.It has no real assist in belt tracking1、“直角托辊架”（90°）这种托辊架与机架垂直，不向前倾，适用于双向运行皮带。
在皮带调整方面没有多大作用.2. "Tilted" (2°) In the di rection of belt travel. Conveyor belts are to run in this direction only. The 2° tilt offers good results in conveyor belt tracking.2、“带倾角托辊架”在皮带运行方向上，皮带只能在倾斜方向运行。
这种2°的倾角在皮带运行时产生良好的效果。
enlarge#2Straight stands can be tilted 2° forward by placing a 1/8" thick washer under the back side of idler stand indicated by arrows. Remember, this conveyor only runs in one direction.如图中箭头所示：通过在托辊后安装一个1/8"厚的垫圈，使托辊架向前倾斜2°。
注意，这种皮带只能向一个方向运行Many times on reversing conveyors, the belt runs great in one direction, only to run off when reversed. Question? What are you using? If you are using tilted stands, they are good for one direction only.大多数情况下，配置这种托辊的皮带在单一方向上运行的很好，只是在皮带反转时才出现问题。
有什么问题吗？你们用的是什么托辊？如果你们正在使用倾斜托辊架，它们只会在一个方向运行。
On reversing conveyors where tilted stands are already in service and giving problems, you can neutralize the tilt by placing a 1/8" thick washer under the front side of the idler stand opposite the side indicated by arrows. Now with the tilted stands neutralized, you can run your conveyor belt either direction.在双向运转皮带上如果安装了这种倾斜托辊并且出现问题，如图所示，可在托辊架倾斜的反方向上安置一个1/8"厚的垫圈来调整。
