2. Product Introduction

This product portfolio covers all core supporting parts for JC135 series brake transmission systems and W250C118A2 clutch equipment, including core brake shaft assemblies, mounting baseplates, brake blocks and brake band assemblies. It is equipped with standard rolling bearings, oil seals, multi-specification bolts, nuts and washers, as well as customized structural parts such as adjusting gaskets, shaft sleeves, pin shafts and pipe fitting components. Auxiliary accessories including shock-proof pressure gauges, ball valves and rope clamps are fully matched to form a complete mechanical braking and transmission system solution. All components adopt precision forging and finishing processes, with unified dimensional tolerance standards and high interchangeability for on-site direct replacement.

3. Core Functional Description

The assembly undertakes heavy-load power transmission, mechanical braking, structural sealing and equipment protection for industrial heavy machinery. JC135 brake shaft assemblies and drum shafts bear high-torque power output to ensure stable equipment operation. Brake band assemblies and brake blocks provide reliable friction braking force to realize accurate equipment parking and emergency stop. Standard bearings and customized shaft sleeves reduce mechanical friction loss during high-frequency rotation. Oil seals and gaskets achieve full-position sealing to prevent lubricating oil leakage and dust invasion. Various fasteners and positioning pins fix the overall structure to avoid displacement and vibration deviation, while pressure gauges and ball valves assist in real-time system monitoring and pipeline control.

4. Structural Characteristics

Adopting integrated modular structural design, this component assembly features high structural rigidity and operational stability. The matched left bearing housing and shaft end cover plate optimize bearing assembly accuracy and reduce operational noise. The combination of elastic washers, split pins and locking wires forms multi-layer anti-loosening protection, adapting to long-term vibration working conditions. Precision adjusting gaskets realize micro-calibration of braking gap to avoid braking failure caused by gap deviation. The integrated clutch guard and connecting flange structure enhance equipment safety protection, and standard sealing accessories effectively extend the service cycle of internal lubricating components.

5. Applicable Working Conditions

This series of components is suitable for heavy-duty and harsh industrial working scenarios, mainly including onshore oilfield hoisting and transportation machinery, mining heavy equipment braking systems, industrial heavy-duty transmission machinery and fixed mechanical operating platforms. It stably adapts to ambient temperatures ranging from -30℃ to 75℃, resisting dust erosion, mechanical vibration and variable load impact. It fully meets the operational demands of long-duration high-torque continuous operation and frequent start-stop braking of JC135 series braking and W250C118A2 clutch transmission equipment.

6. Maintenance Guidelines & Engineer Practical Tips

Professional field mechanical engineers have summarized targeted maintenance norms for this assembly. Inspect the wear degree of brake blocks and brake bands every 30 days to ensure stable braking friction coefficient. Check the flexibility of bearing operation and the sealing integrity of oil seals every 60 days to eliminate oil leakage hidden dangers. Fasten high-load bolts and positioning pins regularly, and replace fatigue failure washers and split pins in a timely manner. Inject lubricating grease through grease nipples every 45 days to reduce shaft sleeve and bearing wear. Standardized cyclic maintenance can extend the overall service life of the brake transmission system by 9200 hours compared with irregular maintenance modes.
