Describe

The Steel Jaw-Type Universal Joint with standard flexible or rigid coupling configurations is a high-performance mechanical component designed to connect two rotating shafts and transmit torque in construction machinery and industrial drive systems. Constructed from high-strength alloy steel, this coupling is available in both flexible and rigid options, making it highly adaptable to different application scenarios.

Engineered for OEM customization, it meets the rugged demands of the construction industry where heavy-duty performance, reliability, and quick maintenance are essential.

Key Features & Advantages
1. Durable Alloy Steel Construction
The coupling is manufactured from premium alloy steel, offering exceptional tensile strength, fatigue resistance, and corrosion protection. It performs reliably in the tough and variable environmental conditions typical of construction sites.

2. Flexible or Rigid Coupling Options
Flexible coupling: Uses a polyurethane elastomer insert to absorb shock loads and reduce vibration, protecting connected equipment.

Rigid coupling: Delivers maximum torque transmission and structural stiffness, ideal for precise shaft alignment.

3. Custom OEM Design Support
Available in various bore sizes, keyway styles, and locking methods (such as clamping hubs, key-and-set screw, or expansion sleeves), the joint can be tailored to fit specific machine models or drive systems.

4. Compact Structure, Easy Installation
The jaw-type design allows quick assembly/disassembly, reducing downtime during on-site maintenance or equipment replacement.

5. High Torque Transmission Capability
Interlocking steel jaws ensure positive engagement and slip-free operation, even under heavy loads or high-frequency torque reversal.

6. Misalignment Compensation (Flexible Version)
In its flexible configuration, the coupling compensates for minor angular, axial, or radial misalignment, supporting easier installation and long-term stability.

Application Areas
This universal joint is ideal for various construction industry equipment and systems, including:

Concrete Mixers & Agitators
Transmits motor power to the rotating drum while damping vibration and torque peaks.

Hoisting & Lifting Machinery
Connects motor drives to load-bearing shafts with dependable power transmission.

Material Handling Systems
Used in belt conveyors, screw conveyors, and chain drives, accommodating shaft misalignment.

Hydraulic Pump Drives & Modular Power Units
Ensures reliable coupling in compact drive units where space and serviceability are critical.

Tunnel Boring Machines (TBMs), Excavators, and Foundation Equipment
Built to withstand continuous operation and heavy mechanical stress.
