This belt, obviously past its prime, ran for 115,000 miles, and it was still within the tension limits specified. It's toast, regardless. There's a squeal emanating from underneath your hood—and it ...

Timing-belt drives transmit torque and motion from a driving to a driven pulley or force to a linear actuator. They may also convey a load placed on the belt surface. A drive under load develops a ...

Despite doing so much, most of us forget the serpentine belt even exists — let alone that its tension matters. But it does. A lot. Too tight and it'll grind bearings to dust. Too loose and you're ...

Over-tensioning shortens not only the life of V-belts but also that of the sheaves, electric motor, and driven equipment bearings. In extreme cases, it can even bend or break a motor shaft.

Belts on a 3D printer should be tight enough, but not too tight. That can be an iffy thing to get right for someone who lacks familiarity with CNC platforms. Prusa Research aims to make it a bit ...
