機器皮帶需要正確緊張，才能好好運作. 如果緊張情緒係「 off,” 皮帶會騎太緊或者太鬆喺滑輪上面. 當呢個情況發生嘅時候, 會有滑落. 熱會由摩擦積聚, 而帶會裂開或者斷裂嘅機會好大.
If a machine belt is too tight, that’s adding stress on the bearings. The motor, then, will likely over amp and, 最終, fail.
Signs of improper Machine Belt Tension
What are some signs of improper machine belt tension? 顯然, if you see cracks in the belt, you’ve got problems. If the belt makes a squealing noise when the machine starts up, that could indicate a tension problem. 也, be on the lookout for a hardened appearance, pieces broken off, and/or pulleys wearing out long before they normally should… And with regards to the motor, if you notice a worn out front motor bearing or there’s over amperage of the motor while the machine is running, you probably have a tension issue.
Seiffert Industrial recommends that belts be tensioned according to manufacturer’s recommendations. Newer belts generally require higher tension levels because they haven’t been “run in.” Ideally, a belt should be tensioned such that the force required to achieve the desired deflection distance is within the belt’s manufacturer’s recommended force values for the type of belt(s) being used.
Keep in mind that belt tension adjustments may alter pulley alignment and pulley alignment adjustments can alter belt tension levels. Seiffert Industrial recommends the 滑輪 pro 對準工具 which can be used to help monitor the pulley alignment condition as belts are adjusted for the correct tension level. We also recommend the 掣聲波張力儀 which measures belt span tension easily and accurately. With this meter, belt tension is measured by plucking the belt span while holding a sensor close by. Belt tension is adjusted until the belt span frequency or measured tension level is within manufacturer’s recommendations.
