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.

    Segment Sprockets in High-Speed and Heavy-Duty Conveyor Systems

    Segment sprockets can be used in certain high-speed and heavy-duty conveyor systems, but their applicability depends on various factors related to the specific application’s requirements and operating conditions. Here’s a detailed explanation:

    High-Speed Conveyor Systems:

    In high-speed conveyor systems, the rotational speed of the sprockets and the conveyor chain or belt increases. This results in higher forces and stresses acting on the sprocket teeth and the chain or belt. For high-speed applications, traditional solid sprockets are often preferred due to their robust construction and ability to withstand higher rotational speeds without compromising performance or causing excessive wear.

    However, segment sprockets can still be used in high-speed conveyor systems if the design and material of the segments are optimized for the specific application’s speed and load requirements. Proper alignment and accurate positioning of the segments are crucial to prevent vibration and ensure smooth power transmission at high speeds.

    Heavy-Duty Conveyor Systems:

    Heavy-duty conveyor systems handle large loads and require sprockets capable of withstanding significant forces and stresses. In such applications, traditional solid sprockets made from durable materials like steel are often the preferred choice due to their high load-carrying capacity and strength.

    Segment sprockets can be used in heavy-duty conveyor systems if they are designed and manufactured with heavy-duty materials and robust construction. High-quality segment sprockets with precise tooth profiles and strong interlocking segments can handle heavy loads and provide reliable power transmission.

    Considerations for Using Segment Sprockets:

    When considering segment sprockets for high-speed or heavy-duty conveyor systems, it’s essential to take the following factors into account:

    • Design and Material: Ensure that the segment sprockets are designed and manufactured with high-quality materials suitable for the application’s speed and load requirements.
    • Proper Alignment: Precise alignment of the segments and accurate positioning of the sprockets are crucial to prevent premature wear and ensure efficient power transmission.
    • Load-Carrying Capacity: Verify that the segment sprockets have the necessary load-carrying capacity to handle the maximum loads encountered in the application.
    • Maintenance: Regular maintenance and lubrication are essential to keep the segment sprockets in optimal condition and prevent unexpected failures.

    In summary, segment sprockets can be used in high-speed and heavy-duty conveyor systems if they are designed and manufactured to meet the specific application’s requirements. Proper selection, alignment, and maintenance are critical to ensuring the segment sprockets’ reliable performance and longevity in challenging conveyor applications.

    Identifying Signs of Wear, Fatigue, or Damage in Segment Sprockets

    To ensure optimal conveyor performance and prevent potential failures, it is essential to regularly inspect segment sprockets for signs of wear, fatigue, or damage. Here are some indicators to look out for:

    • Tooth Wear: Check for signs of wear on the sprocket teeth. Excessive wear may lead to a mismatch with the chain or belt, affecting the smooth motion of the conveyor system.
    • Cracks or Fractures: Inspect the sprockets for any visible cracks or fractures, as these can compromise the sprocket’s structural integrity and lead to catastrophic failure.
    • Deformation: Look for any signs of deformation or bending in the sprocket body. Deformed sprockets may cause chain misalignment and affect the conveyor’s overall performance.
    • Corrosion: In corrosive environments, check for signs of rust or corrosion on the sprocket surface. Corrosion can weaken the sprocket and reduce its lifespan.
    • Excessive Noise or Vibration: Unusual noises or vibrations during conveyor operation can indicate issues with the sprockets. Investigate the source and address any problems promptly.
    • Chain or Belt Wear: Monitor the condition of the chain or belt that interfaces with the sprockets. Excessive wear on the chain or belt may be a sign of problems with the sprockets.
    • Poor Conveyor Performance: If the conveyor system experiences frequent jams, misalignment, or slowdowns, the sprockets could be a potential cause. Investigate and resolve the issues as needed.

    When to Replace Segment Sprockets:

    The replacement schedule for segment sprockets depends on various factors, including the operating conditions, maintenance practices, and the specific material used in the sprockets. As a general guideline:

    • Regularly scheduled maintenance: Incorporate sprocket inspections into routine maintenance tasks to identify any signs of wear or damage early on.
    • Replace worn or damaged sprockets: If any signs of wear, fatigue, or damage are detected during inspections, promptly replace the affected sprockets to prevent further issues.
    • Follow manufacturer recommendations: Adhere to the manufacturer’s guidelines regarding sprocket replacement intervals and maintenance procedures.
    • Consider environmental factors: In harsh environments or high-temperature applications, sprockets may require more frequent replacement due to accelerated wear.
    • Monitor performance: If the conveyor system experiences frequent breakdowns or reduced efficiency, assess the condition of the sprockets and consider replacement if necessary.

    Regular inspection, maintenance, and timely replacement of worn or damaged segment sprockets are crucial for the smooth and reliable operation of the conveyor system.

    segment sprocket

    What is a Segment Sprocket, and How Does it Differ from Traditional Sprockets?

    A segment sprocket, also known as a split sprocket or split rim sprocket, is a specialized type of sprocket design that differs from traditional solid sprockets in its construction and application. The main difference lies in the way the sprocket is assembled and mounted onto the shaft.

    Key Characteristics of Segment Sprockets:

    • Split Design: The segment sprocket is made up of two or more individual segments that fit together around the shaft. These segments can be split in half or divided into multiple pieces, allowing for easy installation and removal without disassembling the entire shaft or conveyor system.
    • Mounting Mechanism: The segments of the sprocket are secured onto the shaft using bolts, clamps, or other fastening methods. This mounting mechanism provides a secure grip on the shaft while still allowing quick and convenient assembly and disassembly.
    • Adjustable Positioning: The segment sprocket’s split design allows for adjustable positioning along the shaft, enabling fine-tuning of the sprocket’s alignment with the roller chain or belt. This adjustability helps optimize power transmission and reduce wear on the chain or belt.
    • Wide Applicability: Segment sprockets are commonly used in applications where frequent sprocket replacement or adjustments are required. They are particularly useful in conveyor systems, where access to the shaft is limited or when the conveyor’s design may change over time.

    Advantages of Segment Sprockets:

    • Easy Maintenance: The split design of segment sprockets simplifies maintenance tasks as they can be replaced or adjusted without fully disassembling the system, reducing downtime and labor costs.
    • Quick Installation: The ability to mount the sprocket segments onto the shaft individually speeds up the installation process compared to traditional sprockets that require sliding over the end of the shaft.
    • Cost-Effective: In applications where frequent sprocket replacement is necessary, using segment sprockets can be cost-effective over time due to reduced maintenance efforts and extended equipment lifespan.
    • Alignment Flexibility: The adjustable positioning of segment sprockets allows for precise alignment with the roller chain or belt, minimizing chain or belt wear and ensuring efficient power transmission.

    It’s important to note that while segment sprockets offer advantages in certain applications, they may not be suitable for all scenarios. In high-speed or heavy-duty applications, traditional solid sprockets may be preferred for their robustness and higher load-carrying capacity.

    In summary, a segment sprocket is a specialized type of sprocket designed for easy assembly, maintenance, and alignment. Its split construction allows for quick installation and adjustments, making it ideal for applications where accessibility and frequent sprocket changes are essential.
