>> Product Name

Excavator bucket bushing.


>> Product Use

Support and positioning

Support components: installed at various connection points of the excavator, such as the connection points between the bucket and the boom, the dipper arm and the boom, etc., to provide precise support for the relatively moving parts, ensuring that these parts can maintain the correct position and posture during the work process, making the movement of the excavator more stable and accurate.

Ensure coaxiality: In some parts with rotating or reciprocating motion, such as the piston rod and cylinder body of the hydraulic cylinder, the transmission shaft and the bearing seat, etc., the bushing can ensure the coaxiality between these parts, reduce the additional stress and wear caused by different axes, and improve the operation accuracy and reliability of the equipment.

Reduce friction and wear

Reduce the friction coefficient: The bushing is usually made of materials with good friction reduction properties, such as bronze, polytetrafluoroethylene, etc., which can form a smooth isolation layer between the relatively moving parts, effectively reduce the friction coefficient, reduce direct contact and friction between parts, thereby reducing energy loss and improving the working efficiency of the excavator.

Protect mating surfaces: When the excavator is working, there will be frequent relative movement and friction between the components. As a wearing part, the bushing can withstand most of the wear and tear, protect the expensive metal parts that match it, such as shaft necks, hole walls, etc., extend the service life of these parts, and reduce maintenance costs.

>> Product Raw Material

Steel

High hardness and strength: After proper heat treatment, the steel bushing can obtain extremely high hardness and strength, can withstand the working load of the excavator under heavy load and high impact conditions, is not prone to cracking and deformation, and ensures the reliability of the bushing under harsh working conditions.

Good machinability: Steel material is easy to carry out various mechanical processing processes, such as turning, grinding, drilling, etc., and can be processed into various complex shapes and sizes according to different use requirements to meet the installation and use requirements of different parts of the excavator.

Strong adaptability to surface treatment: A variety of surface treatment methods, such as chrome plating, nickel plating, nitriding, etc., can be used to further improve the wear resistance, corrosion resistance and friction reduction of the steel bushing, making its performance more superior and adaptable to different working environments.

Raw material preparation

According to the product design requirements, select metal materials such as specific steel grades, such as 45 steel, 20CrMnTi, etc. Ensure the quality of the raw materials and check whether their hardness, chemical composition and other indicators meet the standards.

Rough processing: Use lathes, milling machines, drilling machines and other equipment to rough process the blanks, remove most of the excess, and preliminarily process the inner and outer diameters, lengths, oil grooves and other structures of the bushings, leaving a certain amount of processing allowance for subsequent fine processing.

Fine processing: Use grinding, honing and other processes to fine process the bushings to achieve higher dimensional accuracy and surface roughness requirements. For example, the inner hole of the bushing is ground by an internal grinder to ensure its cylindricity and dimensional accuracy, and the honing process is used to further improve the surface quality of the inner hole and reduce the surface roughness.

Heat treatment

According to the metal material and product performance requirements, the processed bushings are heat treated. For example, the steel bushing is quenched and tempered to improve its hardness, strength and wear resistance; the bronze bushing is subjected to solution treatment and aging treatment to improve its mechanical properties and corrosion resistance.

Surface treatment

To improve the wear resistance, corrosion resistance and friction reduction of the bushing, surface treatment is required. Common treatment methods include electroplating processes such as chrome plating, copper plating, and nickel plating, as well as chemical treatment methods such as phosphating and blackening to form a protective film on the surface of the bushing.

Quality inspection

Use measuring tools such as calipers, micrometers, and three-coordinate measuring instruments to test the dimensional accuracy of the bushing to ensure that it meets the design requirements. Use a hardness tester to test the hardness of the bushing, and use metallographic analysis to check whether the metal structure is normal. Use ultrasonic flaw detection, magnetic particle flaw detection and other means to detect whether there are defects such as cracks inside the bushing.
