1. The pin positioning cone surface or cone hole of the HLL nylon pin coupling is severely worn and corroded, which makes the pin positioning inaccurate, the pin is deflected, and the force of the pin is uneven throughout the week, causing equipment vibration.
2. The elastic ring is severely worn, especially the eccentric wear. If it is reassembled and used again, it will be prone to uneven force and vibration.
3. The overload operation of the equipment causes the pin to bend. After reinstallation, due to the deflection of the pin, the force on the circumference of the elastic pin coupling is uneven, causing the equipment to vibrate.
1. Due to improper maintenance and disassembly process (such as abnormal vigorous beating), the column pin is bent, and after reassembly, due to the deflection of the column pin, the force on the circumference of the coupling is uneven, causing equipment vibration.
2. The weight deviation of each elastic ring column pin is too large after assembly, which will damage the dynamic balance of the shaft system and cause equipment vibration.
3. The fastening force of the pin bolt is too large or uneven, and the elastic ring is squeezed too much, causing the pin to be skewed (maybe there may be processing errors in the taper hole or the pin), causing the elastic ring to be squeezed and deformed, and the force is uneven. cause the device to vibrate.
4. Other forms of damage: such as cracking and deformation of the flange of the coupling, too large or too small matching gap between the inner hole of the coupling and the journal, etc. These defects are relatively common and obvious, and are easy to find and deal with.
