3. Core Functional Description

3.1 Stable Auxiliary Braking Performance

Matched with WCB236 auxiliary brake ring components, JC28 brake hubs and JC32B brake blocks, the product forms a complete auxiliary braking system. It effectively solves the pain point of insufficient auxiliary braking torque and unstable braking state during heavy-load drilling and hoisting, improving equipment operational safety margin in frequent start-stop working cycles.

3.2 Reliable Lubrication & Sealing Protection

Professional oil supply devices, 45° elastic grease fittings and HG4-692-67 standard oil seals form a complete lubrication and sealing system. It avoids insufficient lubrication caused by unsmooth oil supply and equipment abrasion failure, while preventing hydraulic medium leakage and dust invasion in high-dust field environments.

3.3 Precise Transmission & Structural Balancing

Custom shaft sleeves, positioning keys, flanges and XJ40C balance components ensure accurate assembly and stable power transmission of drilling rig transmission structures. It offsets mechanical vibration generated by long-term operation, eliminating transmission jitter and structural deviation faults of host equipment.

4. Structural Characteristics

All accessories adopt modular assembly design with unified industrial tolerance benchmarks, supporting rapid on-site disassembly and replacement without secondary calibration. Core load-bearing parts adopt integral forging and surface hardening treatment, with strong wear resistance and deformation resistance. The matched left and right directional nuts and limit gaskets effectively resist structural loosening under continuous vibration. Optimized oil supply structures and sealing combinations ensure uniform lubrication and comprehensive sealing protection, greatly reducing internal friction loss of mechanical structures.

5. Applicable Working Conditions

This series of accessories is suitable for onshore oilfield drilling, well repair and heavy-load hoisting working scenarios, perfectly matching XJ40C drilling rig and JC28/JC32B supporting systems. It stably adapts to open-air environments with ambient temperatures ranging from -20℃ to 63℃, high dust concentration and frequent mechanical vibration, maintaining stable mechanical performance under long-term intermittent heavy-load and high-frequency cyclic operation.

6. On-site Maintenance Suggestions (Engineer Practical Experience)

Based on accumulated oilfield maintenance experience, auxiliary brake friction parts and sealing components need comprehensive replacement every 9 months to avoid aging failure. Lubrication system accessories should be cleaned and inspected every 3 months to ensure unobstructed oil supply. Transmission shaft sleeves and bearings require regular grease replenishment to reduce dry friction loss. Avoid using mismatched gaskets and fasteners, which will cause equipment operation deviation. Standardized maintenance can extend the continuous stable operation duration of supporting equipment by 2200 working hours compared with irregular maintenance modes.
