Compared with the casting, the shell body of the forged idler has a more uniform structure, better density, better strength integrity, better dimensional characteristics, and smaller dimensional error. The directional structure has higher performance in overall strength and application capability than the casting.



High Strength



Hot forging promotes the refinement of crystallization and grain, maximizing the material strength and consistency and reducing variation between forgings. The granular flow precisely flows along the shell body contour. These continuous streamlines are conducive to reducing the incidence of fatigue or common failures.



The Reliability



One of the most important advantages of forgings is that they can meet the requirements of the designed structure.



The Structural Integrity



Forging eliminates internal flaws and produces a coherent and uniform metallurgical structure assuring optimum performance. Where stress and corrosion problems of crystals are serious, forgings can ensure long service life and problems free service.



The Uniformity



The application of rolling forging technology makes the uniformity of the front Idler dimension. Dimensional uniformity of closed-die forging results in positive control of critical wall thickness, eliminating deficiencies caused by shifted core in castings. High quality and no separation of steel ingot can eliminate internal flaws and produce a coherent and uniform metallurgical structure. The fatigue strength of creep is three times higher than that of casting.

Now more and more new technologies used in Excavator and Bulldozer spare parts manufacture, for example: the friction welding. It has been used in track roller for many years and we are a expert in this area.

Friction welding is a solid-state joining process, which could achieve reliable solder joints and create high-quality, high-strength joints with low distortion. These prolong the working life of the track rollers.

The friction welding track roller has many advantages. In friction welding, the welding allowance of the weldment and the welding power are small, the assembly requirements of the weld are not high, and the electric energy is saved, it is environmentally friendly. Because of high productivity and good quality, it has been widely applied in track roller manufacture.

Why does the friction-welding track roller be better in the wear-resistance and have a longer working lifetime?

Firstly, consumption of raw material: the roller bodies of traditional track roller are connected by the welding rod. but the friction ones are connected by the friction between rollers bodies. So the friction-welding roller will be added more raw material to make sure the roller is perfect to the standard size after welding.

Secondly, inner parts: For the traditional rollers, the welding is done after two processes of maching, so the size of the inner parts are not so precise as friction-welding ones. For the fricion-welding ones, after the weilding, there is one more precise maching with concentric locating to make sure the conformity of inner size,this means the inner parts are more precise with higher standard.

We believe in that there will be more and more new advanced technologies used in Excavator and Bulldozer spare parts manufacture in the future. Our parts will be more stable and have a longer working life. Our durable parts make it possible for your machines to deliver the performance you demand. Protect your investment by always choosing our genuine parts.

Undercarriage parts have a huge effect on working performance and walking performance of excavator. Maintenance is a key to walking speed of excavator. How to maintain your “undercarriage parts”? There are some tips as following.



1. Carrier Roller is above the track frame. The function is to carry and keep the track moving in a straight line. If Carrier Roller has a breakdown, Track Link will not work properly. Carrier Roller is added lubricating oil at once. If oil spills occur, you will have to replace this part. Therefore, you should keep the track frame clean. Don’t let the accumulation of dirt and gravel hamper its work.



2. Front Idler is in the front of the track frame. The function is to prop the track up and guide the track to wind correctly. Besides, Front Idler and Track Adjuster work together to maintain a certain degree of tension on the track. So during working and walking, should keep Front Idler running ahead, which can avoid the wear of the track. Meanwhile, Track Adjuster can reduce the vibration and shedding of the track during walking.

4. During working, Track Roller can’t be immersed in mud for a long time. After working, should support the track on one side. Then, Drive walking motor to get rid of dirt and gravel. In winter, should keep Track Roller dry because there is a floating seal between the outer roller of Track Roller and the shaft. If there is water, it will freeze at night. When the excavator is walking the next day, the floating seal is in contact with ice to cause oil spill. When Track roller is damaged, can cause many faults, such as walking deviation, walking weakness and so on.

5. The track motor guard can protect the motor. However, the dirt and gravel also can enter the interior, which making the oil tube of the motor wear out. Moisture in the dirt will corrode the joint of the oil tube, so regularly open the guard and clean up the dirt inside.

Maintaining the oil track link for a bulldozer involves several steps. Here's a general guide on how to perform maintenance on the track link:

1. Clean the Track Link: Start by removing any dirt, debris, or mud that has accumulated on the track link. Use a high-pressure water hose or a pressure washer to wash away the grime. Ensure that the track link is thoroughly cleaned before proceeding to the next steps.

2. Inspect for Damage: Carefully inspect the track link for any signs of damage, such as cracks, excessive wear, or loose components. Look for any bent or broken track links. If any issues are identified, they should be addressed promptly by replacing or repairing the damaged parts.

3. Lubricate the Track Link: Apply a suitable lubricant or oil specifically designed for the track link. Most bulldozer track links have oil seals and lubricating points. Follow the manufacturer's recommendations regarding the type of lubricant to use and the lubrication intervals. Apply the lubricant evenly to all moving parts of the track link, such as pins, bushings, and rollers.

4. Check Tension and Alignment: Ensure that the track link is properly tensioned and aligned. Too loose or too tight track links can lead to premature wear and reduce machine efficiency. Refer to the bulldozer's manual for the recommended tension specifications, and adjust the track link accordingly.

5. Monitor Wear: Regularly monitor the wear of the track link components. Pay attention to the condition of the track shoes, rollers, and sprockets. Excessive wear may indicate the need for replacement and should be addressed promptly.

6. Track Link Adjustment: If the track link becomes too loose during operation, it will affect the machine's performance and increase the risk of damage. Regularly check the track link for proper tension and make adjustments if necessary. Follow the instructions provided in the bulldozer's manual for adjusting the track link tension.

7. Regular Inspections: Perform routine inspections of the track link and other undercarriage components to identify any potential issues early. This includes checking for loose or damaged bolts, abnormal wear patterns, and oil leaks. Promptly address any problems found during the inspections.

Remember to consult the specific maintenance guidelines provided by the bulldozer's manufacturer for detailed instructions and recommendations tailored to your machine. Adhering to regular maintenance schedules and best practices will help ensure the optimal performance and longevity of the bulldozer's track link.

Introduction

Hardening: Heat treatment techniques such as quenching and tempering can be used to increase the hardness and strength of steel. This is particularly beneficial for components that require high wear resistance, such as cutting tools, gears, and bearings.

Annealing: Annealing involves heating the steel to a specific temperature and then slowly cooling it to soften the material and relieve internal stresses. It improves the machinability, ductility, and toughness of the steel. Annealing is commonly used for components that need to be easily formed or welded, such as sheet metal, rods, and wire.

Stress Relief: Welded or mechanically processed steel components often develop residual stresses that can lead to distortion or reduced mechanical properties. Heat treatment can help relieve these stresses, enhancing the dimensional stability and preventing failures.

Transformation of Microstructure: Heat treatment alters the microstructure of steel, which directly influences its mechanical properties. Processes like quenching, tempering, and austenitizing cause phase transformations that result in desired structures such as martensite, pearlite, or bainite. This, in turn, affects the material's hardness, strength, toughness, and ductility.

Case Hardening: Case hardening treatments like carburizing and nitriding create a hard, wear-resistant surface layer on the steel while retaining the toughness of the core. This is useful for applications where resistance to wear, fatigue, and surface contact is necessary, such as gears, shafts, and camshafts.

Dimensional Stability: Heat treatment can help improve the dimensional stability of steel components, reducing the risk of distortion or dimensional changes that may occur during subsequent machining or usage.

Grain Refinement: Heat treatment can refine the grain structure of steel, resulting in finer grains. This can enhance the material's strength, toughness, and fatigue resistance, particularly in high-stress applications.

It's important to note that the specific heat treatment process and parameters depend on the type of steel, desired properties, and intended application of the final product. Skilled heat treatment practitioners follow established standards, procedures, and control measures to ensure consistent and reliable results in the treated steel products.

Track-chain tension adjustment is the most controllable factor in undercarriage wear life. The accurate track sag of many crawler machines is 2 inches. Due to the complicated ground conditions, Track tension changes with many variations. You should clean out your tracks in daily life.

Cleaning track: Remove out between the track and the roller frame with a shovel, preferably when the packed

material is still wet.

During working, stuck and packed materials between mating components such as rollers, links, sprocket teeth, and bushings improve track tension degree. So tension needs to be adjusted any time packing in the track chain changes.

When crawl machines go along, it should tighten the track up, so getting them cleaned out and adjusted is the important point to undercarriage life.

To measure track-chain tension:

* Roll the machine forward slowly and allow it to roll to a stop.

* Center a track pin over the carrier roller.

* Lay a straightedge or stretch a string over the track grousers.

* Measure sag between the straight edge and grouser tip where the track sags the lowest.

The track adjuster is a grease-filled hydraulic cylinder used to maintain track tension. To adjust track tension, add grease or remove grease from the track adjuster. Eliminating pitch extension, or chain stretch slows sprocket tooth wear and bushing outside-diameter wear.

The excavator track chain, also known as the track link assembly, is a vital component in an excavator’s undercarriage. Its primary functions are closely related to those of track chains in general for tracked vehicles, but with specific considerations for excavators. Here are the main functions of the excavator track chain:



Weight Distribution and Stability:

Like other track chains, the excavator track chain helps distribute the machine’s weight over a larger surface area. This is crucial for preventing the excavator from sinking into soft or uneven terrain and contributes to overall stability during operation.



Traction and Mobility:

The excavator track chain provides traction, enabling the excavator to move efficiently across various terrains. It is particularly important in excavation sites where the ground may be uneven or consist of loose soil, rocks, or other challenging conditions.



Support for the Track Shoes:

The track chain supports the track shoes, which are the components that come into direct contact with the ground. The track shoes help to further distribute the weight of the excavator and provide additional traction.



Durability and Resistance to Wear:

Excavators are subjected to demanding working conditions, and the track chain is designed to be durable and resistant to wear. It must withstand the stress and abrasion associated with digging, loading, and maneuvering in harsh environments.



Ease of Maintenance:

Excavator track chains are designed to be easily maintained. Regular inspection, lubrication, and replacement of worn components are essential to ensure optimal performance and longevity of the undercarriage.



Adjustability:

Some excavators are equipped with an adjustable track tensioning system. This allows operators to adjust the tension in the track chain, ensuring proper track alignment and minimizing premature wear on components.



Smooth Operation:

A well-maintained and properly tensioned track chain contributes to the smooth operation of the excavator. It allows for precise control during digging, lifting, and other tasks, enhancing the overall efficiency of the machine.

In summary, the excavator track chain is a critical component that supports the excavator's weight, provides traction, and contributes to the machine's stability and mobility. Regular maintenance and proper tensioning are essential for ensuring the longevity and optimal performance of the excavator's undercarriage.
