  After the caterpillar bucket teeth pins only had been used for a very short time, but its surface and whole construction has a very bad abrasion and damage problems, to figure out the main reason causing this damage problem happen, writer suggests people to analysis the working surface of the teeth pin first, to confirm the current teeth pin working condition connect with the needed dig materials, because during the whole dig period, with the different working situation, the caterpillar bucket teeth pins will suffer the different pressure.

  But compared with the other parts, the teeth top of the caterpillar bucket teeth pins had to connect with the material surface first, but because the working speed of the caterpillar bucket teeth pins is very fast, so the teeth top part would suffer a very strong impact, so if the yield strength of the caterpillar bucket teeth pins is very low, the teeth top part would easy has the plastic deformation.
 

Prev:Production technical requirements of the teeth pin
Next:With the deeper dig depth, the pressure situation of teeth pin would has some changes
