Bucket Teeth Brief Introduction Part 2
Excavator Bucket tooth is an important part of excavator, similar to human teeth. It must have strong wear resistance, so can effectively prolong the use time of bucket teeth. At the same time, bucket teeth also need strong toughness, which can withstand the impact of high strength, and not easy to break. In addition, due to the using amount of bucket teeth is very large, therefore, it also must have a good economy so as to reduce our cost of use.
Bucket tooth and bucket tooth holder is connected by the lock pin, because the excavator bucket tooth wear failure part is the tooth tip, so when it needs to be replaced, only replace the bucket tooth. When the tip of the bucket teeth is worn more seriously, in the digging operation, the strength required for the bucket to cut into the excavator is bound to increase significantly, which will produce higher fuel consumption and affect the work efficiency. So during the inspection, if found that the bucket teeth appear more serious wear, timely replacement of the new bucket teeth is very necessary.
The appropriated material of excavator bucket tooth is low alloy wear-resistant steel. After casting molding, the casting is properly normalized to improve the structure and performance, and improve the service life. In the use of bucket teeth, you need to see the working environment, which determine the specific bucket teeth type. At present, excavator bucket teeth can be divided into the following categories:
- RC type bucket teeth: used in iron ore, stone ore, etc
- Flat head bucket tooth,used for earthwork, sand, etc
- TL type bucket teeth: used for coal-mining
How to choice good quality bucket teeth?
- Generally marked clear, but almost no mark or mark rough.
- Good quality of side wallis thicker, seat groove and root closely.On the contrary, poor quality of the side wall is thinner, seat groove and the front of the root clearance is generally too large.
- Distinguishfrom the process, good excavator bucket tooth generally use forging process, poor quality of the general use of casting process, because the forging process density is high, so the bucket teeth not only high hardness and wear resistance is very good.
