All precision-machined parts feature strict tolerance control within 0.02mm, guaranteeing high interchangeability and assembly accuracy for industrial transmission and brake systems.

3. Functional Description

This fitting suite supports multiple core mechanical operations for heavy industrial equipment. It delivers consistent torque transmission and power output through GIICLZ12 gear couplings, chain wheels and SY/T standard chains to eliminate power loss and transmission jitter. It ensures reliable braking system operation via high-precision friction hubs and structural foundation plates. It stabilizes hydraulic system pressure within 0–10MPa through KYB18C-HX pressure sensors to avoid pressure deviation faults. It achieves zero-leakage connection through self-sealing quick connectors and multi-specification gaskets. It protects core moving parts via bearing covers, oil baffle rings and protective plates, and realizes accurate mechanical limit and support positioning through support seats and clamping plates.

4. Structural Characteristics

All accessories adopt practical modular structures optimized for field maintenance and replacement. Gear couplings and chain transmission parts feature enhanced tooth profile design to reduce friction wear under frequent start-stop operation. Self-sealing quick connectors realize fast disassembly and assembly without tool damage, improving maintenance efficiency. All standard fasteners and custom JC series parts achieve full-size universal matching without secondary processing. Multi-layer gasket combinations effectively compensate for assembly gaps caused by long-term equipment aging. Reinforced foundation plates and clamping structures resist mechanical deformation and vibration displacement, greatly improving overall structural stability of transmission and brake systems.

5. Applicable Working Conditions

This product set adapts to complex working environments of onshore oilfield production and open-pit mining sites. It stably operates under working pressure up to 10MPa and working temperature ranging from -29℃ to 136℃. It can continuously serve high-dust, high-humidity and strong-vibration industrial equipment, fully meeting operational demands of heavy-duty transmission systems, hydraulic control systems and mechanical brake systems for daily operation, fault repair and seasonal overhaul.

6. Professional Maintenance and Engineer Practical Tips

Based on on-site engineering experience, inspect chain wear and gear coupling operating status every 12 working days to replace fatigued parts in advance. Calibrate pressure sensor data accuracy every 30 working days to ensure real-time hydraulic pressure monitoring validity. Replace aging gaskets and oil baffle accessories quarterly to prevent lubricant leakage. Check bearing operation noise and fastener tightness monthly to eliminate hidden loosening faults. Avoid over-tightening threaded fasteners during installation to prevent thread deformation, which effectively prolongs the overall service life of the matching assembly.
