您希望您的皮带张紧器运行良好，否则就会出现问题! 张紧器在“打开”时始终在皮带上保持适当的张力。如果以及何时紧张是错误的, 然后是其他组件, 像交流发电机或水泵, 会更努力地工作，也更容易失败.
If belt tension is too low, expect slippage. You’ll probably hear a noise, the belt will start to wear down and extremely high temperatures will be created– not good. If belt tension is too high, expect belt-driven accessories to wear down quickly.
What are some belt tension failure signs?
If you notice rust that’s bleeding or dripping from the tensioner, you’ve got internal component wear. You might also be dealing with tensioner cracks or problems with the arm, housing and/or bracket. The tensioner needs to be replaced.
If you have a defective pulley or bearing, you’ll likely hear noise. There will be resistance or roughness, meaning that the pulley bearing is worn out; Replace the tensioner. The same goes for pulley wear in general. Pulleys shouldn’t have chips, cracks or dents.
What about tensioner assembly misalignments? If you notice abnormal belt tracking on the tensioner pulley, you might have a bent/misaligned mounting bracket. There could also be a build-up of corrosion between your tensioner base and mounting surface.
Hearing rattles or squeaks coming from the tensioner? That’s probably a pivot area problem and/or failure of bearings.
If you notice shiny/smooth streaks (or gouges) in your tensioner housing or arm, there’s probably metal-to-metal contact between the arm and spring housing– a misalignment.
Other issues can include excessive tensioner arm oscillation, a binding or grinding tensioner arm movement and/or the loss of spring force. These are all signs of potential belt tension failure.
