What do I need to pay attention to when installing a timing belt?

Hello, you should pay attention to the following points when installing:

1. When installing the synchronous belt, if the center distance of the two pulleys can be moved, the center distance of the pulleys must be shortened first, and then the center distance must be reset after the synchronous belt is installed. If there is a tensioner, first relax the tensioner, then install the timing belt, and then install the tensioner.

2. When installing the synchronous belt on the pulley, remember not to use too much force, or use a screwdriver to pry the synchronous belt to prevent the tensile layer in the synchronous belt from breaking imperceptibly. When designing pulleys, it is best to choose a structure that can move the two shafts close to each other, and if the structure does not allow it, it is best to install the belt and pulley on the corresponding shaft.

3. Control the appropriate initial tension.

4. In the synchronous belt transmission, the parallelism of the axis of the two pulleys is relatively high, otherwise the synchronous belt will deviate or even jump out of the pulley when working. Axis non-parallelism will also cause uneven pressure and early wear of the teeth.

5. The frame supporting the pulley must have sufficient rigidity, otherwise the pulley will cause the two axes to be non-parallel when the combination lock is running.

6. When the synchronous belt is running, it is strictly forbidden to roll solid substances into the cogging, because the tensile layer of the synchronous belt allows very little elongation, and when the foreign matter is rolled in, the synchronous belt will be cut off when it cannot be elongated.

7. When starting, the center distance changes, the belt is relaxed, and the tooth skipping phenomenon will occur, so check whether the frame of the pulley is loose and whether the positioning of the shaft is inaccurate. Adjust and reinforce.

8. The tensioner must be installed on the back side of the belt.

9. The most important point is that the installation should ensure that the machine is in the case of power failure, safety first.

Guangzhou Qingchuan will answer for you: for the installation of the synchronous belt, first of all, we need to turn off the power supply, remove the protective cover, and loosen the assembly bolts of the motor. Move the motor to make the timing belt loose enough that you can remove the timing belt without prying, and never pry the old timing belt directly off.

Remove the old timing belt, check for abnormal wear and record it, excessive wear and tear may mean that there is a problem in the design or maintenance of the transmission, and improvements can be made based on these.

After that, clean the timing belt and timing pulley to be replaced, wipe the rag with a little non-volatile liquid, soak it in detergent or use detergent to scrub the timing belt. Also be careful not to wipe with sandpaper or scratch with sharp objects, and ensure that the timing belt is kept dry before installation and use. Check whether the pulley is linear symmetrical, the synchronous pulley is linear symmetrical to the transmission belt, especially the operation of the synchronous belt transmission device is very important, after the inspection, you can install it in the opposite way according to the way of disassembling the old synchronous belt.
