How to Improve the Service Life of Excavator Bucket Teeth?

As one of the main components of excavators, excavator bucket teeth are of great importance in the process of excavating. The bucket teeth are not only subjected to sliding wear, but also bear a certain impact load, which greatly shortens the service life of the bucket teeth.

 

 

Reasons Why do Bucket Teeth Wear

There are many kinds of buckets, such as mini excavator buckets, excavator screening bucket, trenching bucket for mini excavator, etc. which are available for you to choose from. As we all know, the bucket teeth will be replaced after the excavator has been used for a period. That is because when the excavator is working, each working surface of the bucket tooth is in contact with the excavated object, and the force is different in different working stages of the excavation process.

 

First, when the bucket teeth are in contact with the surface of the material, due to the high speed, the tip of the bucket will be subjected to a strong impact load. When the yield strength of the bucket tooth material is low, the tip of the bucket tooth will undergo plastic deformation. As the digging depth increases, the pressure on the bucket teeth will change.

 

And then, when cutting the material, the relative movement between the bucket tooth and the material will produce a great squeeze on the surface, which will cause friction between the working surface of the bucket tooth and the material. If it is hard rock, concrete, etc., the friction will be greater.

 

This process repeatedly acts on the working surface of the bucket teeth, resulting in varying degrees of wear. And deep grooves will result in the bucket teeth being scrapped. Therefore, the quality of the wear-resistant layer on the surface of the bucket teeth directly affects the service life of the bucket teeth.

 

 

Ways to Help to Improve the Service life of Bucket Teeth

We should choose the right welding material, which is very important for us to improve the wear resistance of bucket teeth. High manganese steel which is widely used in high impact wear conditions is highly recommended. To obtain bucket teeth with good wear resistance, it is usually necessary to further optimize the material composition to achieve the designed high hardness and high toughness composition.

 

The bucket teeth on both sides of the excavator wear are about 30% faster than the middle part. Therefore, the teeth on both sides and the middle can be used interchangeably, reducing maintenance times, and indirectly increasing the service life of the teeth. In addition, before the bucket teeth reach the service limit, repair them in time. Moreover, if you can’t fix it, consider replacing it with a new one. Bucket chain excavator, excavator tilt bucket, excavator rock bucket, etc. are good choices.

 

Besides, there are also some precautions when working with excavators. When digging, the bucket teeth should be perpendicular to the working surface, so as not to break the bucket teeth due to excessive tilt. When the resistance is large, avoid the excavating arm swinging from side to side to avoid the bucket teeth and gear seat from breaking due to excessive left and right forces.
