Excavator and Bulldozer Undercarriage Sprockets and Segments

Sprockets are essential parts of most crawler equipment, including excavators, dozers, cranes, drilling machines, and more. Proper undercarriage maintenance significantly lessens the chance for a larger breakdown in the middle of an important job. Sprockets and segments work with the undercarriage track to drive track-style equipment movement. If your sprockets and segments show wear, chances are that you will need to look into replacement parts.

Sprockets Vs. Segments

Sprockets are metal gears with an inner ring that has bolt holes or a compression hub and gear ring all within a single unit. In contrast, segments are individual pieces that can be linked together to form a metal ring. This means segments can be combined to create the effect of a complete sprocket, but are able to be individually replaced without dismantling the entire track.

Sprockets & Segments – CZPT or OEM Parts

Heavy machinery undercarriages help to carry tons of weight and propel movement. If your undercarriage experiences significant use, it will likely need repair and replacement parts. Original equipment manufacturer (OEM) parts are produced at the same factory that makes the equipment they are used for. Purchasing an OEM part ensures that the part will be identical to the part initially included in the vehicle at purchase. One might think these are the only high-quality replacement options, but CZPT part manufacturers provide replacement parts at a much lower price without sacrificing the machine match or quality.

Heavy Equipment Undercarriage parts

Quality heavy machinery undercarriage parts help prevent premature wear on excavators, dozers, track loaders, skid steers, and forestry equipment. The majority of maintenance and part costs for track-type equipment is from its undercarriage. That means, selecting high-quality parts is essential to keeping your machines running efficiently and to save costs.

Vochains offers undercarriage parts designed to provide the greatest return on your investment and extend the wear life of your machines

Track Equipment Undercarriage Parts

Track Assemblies  – CZPT carries complete track group assemblies in addition to individual steel and rubber tracks. Track groups can be shipped pre-assembled to make your installation even easier.

Sprockets, Idlers, & Segments – Vochains offers a wide selection of sprockets that are designed for extended life, high resistance, and increased durability. Our idlers and rollers can help your crawlers, bulldozers, and excavators handle even the most intense applications.

Track Shoes & Track Pads – Vochains has a variety of track shoes for any environment with a variety of designs, profiles, and widths. Our premium track shoes are built to handle even the highest impact conditions without bending or breaking.

Track Links – Vochains carry heavy-duty Track links that hold track sections together and keep your equipment functioning properly in even the harshest applications.

Track Adjusters – Vochains offers track adjusters that can directly replace your existing parts with a quick replacement. Track adjusters help to absorb shock and protect your machine from leakage while minimizing the risk of releasing the spring.

Track Chains – Vochains’ track chains are available in different versions to match your machine and environment. With track chains designed for easy installation, you can save time and money while increasing the performance of your machine.

Rollers – Vochains supplies track rollers are designed for a long wear life and strong performance even in the most extreme operating conditions. Increase the undercarriage clearance height to reduce the load on the front wheel, sprocket, and final drive. Top, bottom, and carrier rollers can decrease the weight on costlier parts, increasing overall wear life. By investing in quality rollers, you can save costs in the long run.

Pins & Bushings – Pins and bushings form the hinges that allow the links of the track chain to move around the sprockets & idlers. As pins and bushings naturally wear it primarily occurs on a single side of the pin and the matching surface of the bushing, which allows the track pitch to extend, causing a stretched chain that runs loose. Maintaining proper pins and bushings will keep your undercarriage tracks running effectively.

 

Routine Undercarriage Maintenance

When inspecting your equipment’s undercarriage, you are looking to see that everything is in its correct place and working properly.
This includes things such as:

Maintaining proper track tension.
Both loose and tight tracks can cause issues preventing your machine from functioning properly.

Using appropriate track shoes for different job sites.
Depending on the type of movement your machinery will be doing and the terrains you’ll be working in, choose track shoes that work well.

Signs of significant wear on the idlers.
Notable tread will appear as deep pockets or grooves across the surface of the idler.
You also want to ensure that a lip has not formed on the edge of the idler. If so, this lip indicates that it may be time for servicing.

Keeping your undercarriage clean and well-lubricated.
Build-up of dust, mud, and debris can impact lubrication and make your equipment more difficult to use, which may cause operators to be a bit rougher when forcing it to maneuver or operate.

Inspecting frequently.
Frequent and thorough inspections, preferably with an operator’s manual in hand, can help operators spot wear, damage, and other issues before they get out of hand and result in more significant repair costs.

These visual inspections should occur daily.

    Materials Used for Manufacturing Segment Sprockets and Their Properties

    Segment sprockets are manufactured using various materials, each chosen for its specific properties and suitability for the intended application. The choice of material affects the sprockets’ durability, strength, and resistance to wear and environmental factors. Here are some common materials used for manufacturing segment sprockets and their properties:

    • Steel: Steel is one of the most widely used materials for segment sprockets due to its excellent strength, durability, and wear resistance. Carbon steel and alloy steel are commonly utilized. These sprockets are suitable for heavy-duty applications and can withstand high loads and abrasive environments.
    • Stainless Steel: Stainless steel segment sprockets are highly corrosion-resistant, making them ideal for applications where exposure to moisture or chemicals is a concern. They are commonly used in food processing, pharmaceuticals, and outdoor environments.
    • Plastic: Plastic segment sprockets are lightweight, corrosion-resistant, and quieter compared to metal sprockets. They are commonly used in conveyor systems where reducing noise and weight is essential. However, they may have limited load-carrying capacity and may not be suitable for heavy-duty applications.
    • Nylon: Nylon segment sprockets offer good wear resistance, low friction, and high impact strength. They are often used in applications where self-lubrication is beneficial, such as in low-speed and low-load conveyor systems.
    • UHMWPE (Ultra-High-Molecular-Weight Polyethylene): UHMWPE segment sprockets possess excellent wear resistance and low coefficient of friction, making them suitable for applications involving abrasive materials. They are also self-lubricating, reducing the need for additional lubrication.
    • Acetal (Polyoxymethylene or POM): Acetal segment sprockets offer good mechanical properties, low friction, and resistance to moisture and chemicals. They are commonly used in conveyor systems and material handling equipment.
    • Cast Iron: Cast iron segment sprockets are known for their high strength and durability. They are commonly used in heavy-duty applications, especially in environments where shock loads and high temperatures are present.

    The choice of material for segment sprockets depends on factors such as the application’s load requirements, operating conditions, environmental factors, and desired performance characteristics. Proper material selection is crucial to ensuring the sprockets’ longevity, efficiency, and reliability in the specific machinery or equipment.

    When selecting segment sprockets, it’s essential to consult with manufacturers or industry experts to determine the most suitable material that matches the application’s needs and optimizes the overall performance of the conveyor system or machinery.

    Calculating Required Torque and Power for a Segment Sprocket Setup

    Calculating the required torque and power for a segment sprocket setup involves considering several factors related to the conveyor system’s design and operation. The torque and power requirements depend on the following key parameters:

    • Conveyor Load:
    • Determine the total load being conveyed by the system, including the product weight, conveyor belt or chain weight, and any additional accessories.

    • Conveyor Speed:
    • Measure the speed at which the conveyor system operates, typically in meters per second or feet per minute.

    • Segment Sprocket Diameter:
    • Know the diameter of the segment sprocket being used in the setup.

    • Efficiency and Coefficient of Friction:
    • Consider the efficiency of the conveyor system and the coefficient of friction between the conveyor chain or belt and the segment sprockets.

    Calculating Torque:

    To calculate the required torque for a segment sprocket setup, you can use the following formula:

    Torque (Nm) = (Total Load * Conveyor Speed) / (Segment Sprocket Diameter / 2) * Efficiency

    Calculating Power:

    To calculate the power requirement for the conveyor system, use the formula:

    Power (Watt) = (Torque * Conveyor Speed) / (9.55)

    where 9.55 is a conversion factor to convert torque in Nm to power in watts.

    Considerations:

    • It’s essential to use consistent units throughout the calculations.
    • Factor in safety margins to ensure the conveyor system has adequate power reserves to handle unexpected load variations.
    • Account for any incline or decline in the conveyor’s path, as it can affect the required torque and power.
    • Ensure that the selected motor and drive system can deliver the calculated torque and power efficiently.

    Keep in mind that the above calculations provide theoretical values, and real-world conditions may affect the actual torque and power requirements. It’s advisable to consult with conveyor system manufacturers or engineering professionals for accurate calculations tailored to your specific segment sprocket setup and application.

    Can You Explain the Working Principle and Function of a Segment Sprocket?

    The working principle of a segment sprocket is based on its unique design, which allows it to be easily assembled, adjusted, and mounted onto a shaft without the need for complete disassembly of the system. The segment sprocket consists of two or more individual segments that fit together around the shaft.

    Working Principle:

    • Segmented Construction: The segment sprocket is divided into multiple pieces that can be split in half or separated into smaller segments.
    • Mounting Mechanism: Each segment is equipped with bolt holes or clamping features that allow it to be secured onto the shaft using bolts or clamps.
    • Adjustable Positioning: The split design of the segments enables them to be positioned and adjusted independently along the shaft, ensuring precise alignment with the roller chain or belt.

    Function of Segment Sprockets:

    Segment sprockets are utilized in various applications where frequent sprocket replacement, adjustment, or maintenance is required. The primary functions and advantages of segment sprockets include:

    • Easy Installation and Replacement: The segmented design simplifies the installation process as each segment can be mounted individually onto the shaft, making it easier to fit the sprocket into tight spaces or constrained environments.
    • Quick Adjustment: The adjustable positioning of the segments allows for fine-tuning of the sprocket’s alignment, which is particularly beneficial in conveyor systems where precise sprocket positioning can optimize power transmission and reduce wear on the chain or belt.
    • Minimizing Downtime: When maintenance or replacement is necessary, segment sprockets can be disassembled and reassembled rapidly, reducing system downtime and increasing operational efficiency.
    • Cost-Effectiveness: In applications that require frequent sprocket changes or adjustments, the use of segment sprockets can be cost-effective in the long run due to reduced labor and maintenance costs.

    Segment sprockets find extensive use in conveyor systems, material handling equipment, agricultural machinery, and other applications where the ability to quickly replace or adjust sprockets is advantageous. However, in high-speed or heavy-duty applications, traditional solid sprockets may still be preferred for their higher load-carrying capacity and durability.

    In summary, the working principle and function of a segment sprocket revolve around its split construction, which allows for easy assembly, adjustment, and replacement. This unique design provides practical benefits in applications that require frequent sprocket changes and precise alignment with roller chains or belts.
