How can Bucket Teeth wear and drought?

As a Komatsu Bucket Teeth Wholesale, share the relevant knowledge with you. Because of the composite material of high manganese and alloy steel has strong toughness, it can be hard facing wear-resistant alloy on the surface, which can greatly increase the surface strength of the bucket teeth, thereby obtaining the ideal bucket teeth. Due to the strong principle in the drought resistance process, the surfacing alloy with high hardness and good wear resistance should be selected on the material to improve the anti-wear ability of the excavator.

Komatsu Bucket Teeth

Many reasons for the wear failure of Komatsu Bucket Teeth are caused by the unreasonable design of the process structure, especially in the overall structure and part structure. Bucket teeth are easily damaged during long-term excavation, and their service life is relatively low, which seriously affects the efficiency of construction. Therefore, to improve the wear resistance of bucket teeth, it is necessary to change from its original form. In terms of the overall structure, a long groove can be dug in the lower part of the bucket teeth, and then the metal is placed in the appropriate place to increase the length of the bucket teeth. Not only can it increase the effective amount of metal wear, but it also changes the force flow when the ore is in contact with the part, effectively improving its degree of wear resistance. In the part 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. Reasonably design the bucket lip bucket tooth and bucket tooth angle. If the bucket tooth angle is too large, it will increase its bending impact stress, which will cause the bucket tooth to break. If the included angle of the bucket teeth is too small, it will cause the relative movement of the bucket teeth and the grinding surface, which will lead to wear failure. Therefore, when designing, the corresponding design should be made according to the area where the excavator is operated and its angle can be adjusted to the best, which can reduce the energy consumption of the equipment and reduce the tooth wear. It is necessary to carry out a comprehensive design for wear-free lubrication and non-wear lubrication, and at the same time to make structural improvements for the effect of force and the mutual improvement of the direction of force flow.

The improved bucket tooth torque becomes longer and the sharpness of the tooth tip becomes flat. This can reduce the friction and pressure on the tooth tip per unit area and fundamentally solve the problem of tooth wear failure. Large mining excavators are prone to wear during use, which is difficult to avoid, but designers can take corresponding measures to continuously improve the degree of wear, increase service life and improve operating efficiency. When improving, the designer should proceed from the actual situation and make corresponding changes to its structure and materials to improve its abrasion resistance. If necessary, the surface can be treated with drought resistance. At the same time, designers should select materials reasonably, do a good job of surface treatment, and continuously improve the wear resistance of bucket teeth of large excavators.
