  • Product overview

Force analysis the working face of bucket tooth pedestal is in contact with the object to be excavated. In a complete excavation process, the force condition is different at different working stages. When the tooth tip first contacts the surface of the material, the tooth tip of the bucket is strongly impacted due to its fast speed. If the yield strength of bucket teeth is low, plastic deformation will occur at the tip. With the increase of excavation depth, the force on bucket teeth will change. When the bucket teeth cut the material, the bucket teeth and the material move relative to each other, resulting in a great positive extrusion force on the surface, thus creating a greater friction between the bucket teeth working face and the material. If the material is hard rock block, concrete, etc., the friction will be great. The repeated action of this process results in different degrees of surface wear on the bucket tooth working face, and then produces deep furrow. The composition of bucket teeth affects the service life of bucket teeth. It can be judged that the positive pressure and friction are the main external mechanical factors of bucket tooth failure, which play a major role in the process of failure.

1: The material of the bucket tooth seat is low alloy wear-resistant steel, which is suitable for bucket teeth. However, due to the lack of necessary heat treatment, the structure of the bucket teeth is uneven, the insert does not play its due role, and the overall wear resistance of the bucket teeth seat is poor, leading to early failure.

2: It is suggested that proper normalizing should be carried out after casting to improve the structure, properties and service life. After reasonable heat treatment of the casting, the service life of the bucket tooth seat is increased by nearly two times under the same working conditions.
