1、 Too much deviation of parallelism between axes
If it is the problem of parallelism offset between belt shafts, we need to improve the parallelism of the belt axle. If the offset between the shafts between the pulleys is too large, it must be corrected reasonably.
2、 Insufficient tension in the belt falling direction
When the belt is driven, the belt falls off, which increases the tension in the direction of belt falling off.
3、 Adjust the tensioning wheel properly
If the transmission has the tensioning wheel, we can also adjust the tension device of the belt synchronously to make the drive belt be properly tensioned to avoid the belt falling off again.
4、 Is the belt bent
The uneven and bending of the belt will also cause the belt to fall off; Check whether the belt is bent or bent will affect the normal transmission of the flat belt, if any, it needs to be corrected.
5、 Whether the belt joint is skewed
Flatness of the joint of the flat belt also affects whether the belt is smooth, and check whether the belt joint is skewed, and if necessary, it needs to be corrected.
6、 Add guide strip on the flat belt to prevent falling off
The plane belt with guide strip is an effective solution to drive belt deviation and fall off, but it needs to be slotted on the pulley.
