Many bucket tooth wear failures are caused by unreasonable design of structure. Therefore, in order to improve the wear resistance of bucket tooth, the structure morphology can be changed.

In the overall structure, the long groove can be changed into a round hole, which can not only achieve the effect of anti-wear, but also improve the phenomenon of stress concentration. At the same time, the bucket lip bucket tooth and bucket tooth angle should be reasonably designed. If the bucket tooth angle is too large, it will increase the bending impact stress, thus causing bucket tooth to break. If the angle between the bucket tooth is too small, it will cause the relative motion between the bucket tooth and the grinding surface, which will lead to wear failure.

In the design, the designer should proceed from the actual situation and adjust the angle according to the function of force and the direction of force flow. It can not only reduce the energy consumption of excavator, but also reduce the abrasion of bucket tooth, and make corresponding changes to its structure and material. When necessary, special surface treatment can also be carried out to improve its wear resistance.
