Under the extreme conditions of mining and heavy construction, power transmission faces not only the challenge of high torque but also severe vibration and shock. The Connector Assembly serves as the "joint" of power transmission, located between the engine and gearbox . Its core mission is to reliably transmit torque while efficiently absorbing shock.
Designed specifically for mining drill rigs and heavy construction machinery, this product combines a high-quality cast steel main body with alloy steel spring components, supplemented by wear-resistant rubber damping elements. It offers exceptional structural strength, torque transmission capacity, and shock absorption performance. As a critical spare part for the clutch system, it ensures smooth power transmission and stable equipment operation even in the harshest mining environments.
High-Quality Cast Steel: The main frame is manufactured from high-strength cast steel such as ZG270-500 or ZG35CrMo. Compared to cast iron, cast steel offers higher yield strength and impact toughness, enabling it to withstand the massive reaction forces and torsional vibrations generated when drill rigs penetrate rock formations, preventing overload fractures.
Precision Casting & Machining: Utilizing resin sand casting ensures a dense internal structure, followed by CNC precision machining to guarantee flange flatness and mounting hole accuracy. This ensures the coaxiality of the assembly with the flywheel and gearbox, preventing additional radial loads caused by misalignment, thus protecting bearings and oil seals.
Alloy Steel Springs: Spring components are selected from 60Si2MnA or 50CrVA spring steel, undergoing precision stamping and heat treatment . This imparts an extremely high fatigue limit, allowing the springs to resist fracture during millions of compression and rebound cycles, maintaining stable stiffness.
Wear-Resistant Rubber Elements: Made from a composite of natural rubber and nitrile rubber, bonded firmly to the metal components via vulcanization. The rubber not only cushions shocks but also isolates high-frequency noise. A special formula makes it oil-resistant and aging-resistant, preventing hardening and cracking even when soaked in oil or exposed to high temperatures.
Dual Surface Protection: The main housing features black spray-paint, while the spring components undergo oxidation treatment. This protective armor effectively isolates corrosion from acidic mine water, mud, and chemicals, preventing rust and seizure, thereby significantly extending service life.
Superior Torque Transmission: The design prioritizes the rigidity of power transmission. When the equipment requires a burst of power the assembly instantly locks, transferring every ounce of engine power without loss to the travel or work devices.
Efficient Shock Absorption: When encountering hard rock layers or rough terrain, the spring and rubber elements deform elastically, absorbing and dissipating impact energy like "Tai Chi." This protects the engine crankshaft and gearbox gears from violent shocks, significantly reducing the risk of shaft breakage and gear chipping.
Torsional Vibration Damping: The torsional vibration generated by internal combustion engines is an invisible killer of transmission systems. Acting as a damper, this assembly effectively cuts off and attenuates self-excited vibrations, preventing component fatigue damage caused by resonance.
As a Critical Spare Part, this connector assembly is widely used in:
Mining Drill Rig Transmission Systems: Connecting the engine to the hydraulic pump group, absorbing reactionary torque shocks during drilling.
Heavy Construction Machinery: At the junction of engines and gearboxes in large excavators and bulldozers.
Mining Dump Trucks: Used between drive shafts to accommodate chassis torsional deformation.
Crushing & Screening Equipment: Connecting motors to crushing hosts, buffering instantaneous overloads during material crushing.
