The bucket tooth manufacturing process has been comprehensively optimized: from torque and lubrication to material selection.

The wear and failure of bucket teeth is not a single structural problem, but the result of the combined effect of multiple factors such as overall torque, component details, lubrication design, and material selection. To fundamentally solve the wear problem, a comprehensive optimization of the process and structure is required to achieve the goal of "reasonable stress distribution, controllable wear, and maximized service life."

Core Optimization Dimension 1: Torque and Tooth Tip Shape Optimization to Reduce Unit Stress

The optimized bucket teeth reduce wear from a mechanical perspective by extending the torque and smoothing the tooth tip: the longer torque distributes the force during digging more evenly, avoiding local overload on the tooth tip; the flatter tooth tip increases the contact area with the material, reducing friction and pressure per unit area, thus slowing down the wear rate at its source. This design is particularly suitable for large mining excavators, effectively coping with the instantaneous impact and continuous wear caused by high-intensity excavation.

Core Optimization Dimension 2: Lubrication System and Force Flow Design to Reduce Ineffective Friction

Comprehensive optimization of "wear-reducing lubrication" and "wear-free lubrication" solutions: Lubrication channels are added to the connection between the bucket teeth and the bucket lip, and special wear-resistant grease is injected to reduce friction loss caused by relative motion; at the same time, combined with the optimization of the overall structure and component structure, the force flow direction is further improved, allowing the impact force during material contact to be reasonably transmitted along the bucket teeth, avoiding ineffective friction and localized wear, achieving a virtuous cycle of "force-wear" interaction.

Core Optimization Dimension 3: Material Selection and Surface Treatment to Strengthen Wear Resistance

Structural optimization must be combined with appropriate material selection and surface treatment: wear-resistant base materials such as high-chromium molybdenum alloy are selected to ensure the basic performance of the structural optimization; if necessary, the surface of the bucket teeth is hardened (such as quenching, spraying wear-resistant coating) to further improve surface hardness and wear resistance. The synergistic optimization of structural design, materials, and surface treatment allows the wear resistance of the bucket teeth to achieve a "1+1>2" effect.

Summary

The comprehensive optimization of the bucket tooth design and structure represents a systematic upgrade "from principle to detail"—addressing the root cause of wear and failure due to structural deficiencies through multi-dimensional measures such as torque adjustment, improved lubrication, and material upgrades. For heavy-duty equipment such as large mining excavators, this comprehensively optimized bucket tooth not only significantly extends service life but also reduces equipment energy consumption and maintenance costs, providing a solid guarantee for efficient construction and becoming a "durability benchmark" under heavy-duty working conditions.
