Larger excavate speed and excavate force would lead to hardened friction between bucket tooth sleeve and tooth holder

Even there has no impact force exist in the excavate work conditions,but if excavator drivers or operators has control the excavator machine and China bucket tooth pin with too large excavate speed, so because of the too large excavate force and excavate speed, there would appear the certain harden friction between excavate bucket tooth sleeve and tooth holder and causes the portion higher temperature.

In the common excavate working condition, because of the too worse and harsh work state, both of the water and gas would be rapid heat among the gap between the China bucket tooth pin tooth holder and teeth sleeve, and the entirety excavator bucket tooth, which external appearance has a low roughness degree would easily has rust damage.

Under the too large excavate force effect, the external surface hardened layer and metal phase organization for China bucket tooth pin would be damaged with faster speed, especially of the surface oxygen film has wiped off, the gap between the excavator bucket tooth holder and tooth sleeve would become larger and larger, but the entirety China bucket tooth pin would never match with the running requirement anymore.
