Common types of edge teeth for construction machinery
The common types of edge teeth for construction machinery can be classified from three dimensions: tooth profile structure, application scenarios, and compatible models. Specifically, they are as follows:
I. Classification of Tooth Profile Structures
Straight tooth type
The tooth surfaces are arranged in a straight line, which is simple to manufacture and has a low cost. However, it has a relatively large impact during operation and is suitable for low-load working conditions (such as the loading of light materials).
Typical features: Straight tooth tips and evenly distributed tooth grooves.
Conical tooth type
The tooth surface is designed with a taper to enhance the cutting ability and reduce the lateral splashing of materials, making it suitable for medium and high hardness earthwork operations.
Typical feature: The tooth profile gradually shrinks from the root to the top, forming a wedge-shaped structure.
Compound tooth profile
Helical teeth : The tooth surface is designed to be inclined, reducing meshing impact and extending service life (commonly seen in high-frequency operation equipment).
Herb-shaped teeth : V-shaped symmetrical tooth pattern, counteracting axial force and enhancing stability (suitable for large loaders).
Ii. Application Scenario Adaptation
Type Applicable equipment typical working conditions performance advantages
The forged flat sharp tooth 60-650 type excavator has strong impact resistance to loose sand and clay and high cost performance
Diamond reinforced teeth large loaders (such as XG953-Ⅲ) mine crushed stone, frozen soil super-hard alloy surface layer, wear resistance increased by 40%
Guard plate type edge teeth excavator bucket arm (such as PC450-8) rock stripping, heavy load impact integrated protective plate, reducing bucket body deformation
Note: The UE series (general type) and PC series (Komatsu dedicated) are the mainstream model standards in the industry.
Iii. Special Functional Variants
Rack side teeth
Convert the rotational force into a linear cutting force and apply it to the edge of the bulldozer blade to enhance the efficiency of demolition on hard ground.
Embedded edge tooth
The tooth root is embedded into the internal structure of the bucket body, reducing welding stress and preventing the tooth seat from cracking (commonly seen in high-frequency vibration conditions).
Selection suggestions : Straight tooth type is suitable for routine earthwork operations, conical tooth type is suitable for hard materials, and composite tooth type is preferred for high-frequency and heavy-load scenarios; The specific model must strictly match the equipment parameters (such as bucket capacity, hydraulic pressure) and the technical specifications of the manufacturer.
