Shanghai Jiteng is a professional manufacturer and supplier of Torque Limiters in China. As a core overload protection component within industrial transmission systems, this product functions much like a mechanical fuse: it can instantaneously interrupt power transmission when equipment jams or loads exceed safe limits, thereby safeguarding the integrity of critical components such as motors and reducers. It is an essential safety device for automated production lines and stands as one of our factory's five core transmission products.
The Torque Limiter is a specialized mechanical safety component designed exclusively for industrial equipment. Unlike conventional transmission couplings—whose sole purpose is to transmit torque—the Torque Limiter prioritizes fail-safe protection, preventing severe mechanical damage to equipment right at the source of the transmission chain.
1. Mechanical Fuse-style Safety Protection: Analogous to the operational logic of an electrical fuse, the device can instantaneously cut off power transmission during emergency conditions—such as material jamming, rotor lock-up, or sudden overloads—thereby eliminating the risk of overload-induced torque surges damaging critical components.
2. Safeguarding High-Value Core Equipment Components: It provides targeted protection for high-precision, high-value components—including motors, reducers, lead screws, and spindles—preventing irreversible damage caused by sudden equipment malfunctions and significantly reducing the risk of equipment write-offs.
3. Essential Accessory for Automated Production Lines: Designed to integrate seamlessly with automated and intelligent continuous production environments, it addresses the inherent limitation of standard couplings—namely, their lack of overload protection—making it an indispensable safety accessory for modern industrial production lines.
1. Normal Transmission Stage: Stable, Zero-Backlash Torque Transmission: When the equipment's operating torque remains below the preset safety threshold, the driving and driven ends of the torque limiter remain rigidly engaged. This ensures zero backlash, zero slippage, and zero idle travel, allowing for continuous and stable power transmission without compromising the equipment's normal production efficiency.
2. Overload Protection Stage: Instantaneous Disengagement and Power Cut-off: Should conditions arise—such as material jamming, equipment malfunction, or a sudden surge in load—causing the actual torque to exceed the preset limit, the internal actuating mechanisms (including steel balls, rollers, or friction plates) will instantly disengage. The driving and driven ends rapidly slip apart, instantaneously severing the power transmission and preventing the excessive torque from damaging the equipment's structural components.
3. Reset and Recovery Phase: Rapid Resumption of Operations and Maintenance: Once the overload fault—and its underlying cause—has been diagnosed and cleared, most models are capable of automatic resetting, allowing for a swift return to normal power transmission. A select few models, designed for specific operating conditions, support manual resetting; this adaptability allows them to suit diverse equipment operating environments and protection requirements, offering exceptional flexibility.
1. Ball-Type Torque Limiter: Features a highly sensitive structure and rapid response speed, ensuring precise overload triggering. It is ideally suited for precision automation equipment and transmission scenarios involving small to medium torque loads, offering high accuracy in fault detection.
2. Friction-Type Torque Limiter: Provides smooth power transmission and excellent cushioning capabilities. It is suitable for operating environments characterized by frequent load fluctuations and a need for continuous slip-cushioning, demonstrating superior fatigue resistance.
3. Roller-Type Torque Limiter: Boasts a strong load-bearing capacity and high shock resistance. It is designed for medium-to-heavy-duty industrial equipment involving high torque loads, capable of enduring prolonged exposure to alternating load impacts.
4. Pin-Type Torque Limiter: Features a simple structure and offers excellent cost-effectiveness, maintaining a stable overload protection threshold. It is well-suited for basic overload protection scenarios involving standard, general-purpose mechanical equipment.
1. Significantly Reduced Equipment Failure and Maintenance Costs: By preventing overload-induced component fractures, wear, and damage at the source, the frequency of spare parts replacement is reduced. This effectively minimizes the loss of production capacity and the labor costs associated with equipment downtime and repairs.
2. Extended Overall Service Life of Core Equipment: By continuously cushioning and isolating excessive impact torque, the device protects high-value core components—such as motors and reducers—from damage. This slows down the rate of equipment aging and extends the overall service life of the entire machine.
3. Compatibility with Intelligent Automation Production Needs: Perfectly aligns with the operational standards of automated and intelligent production lines. It enables early fault warnings, rapid power disconnection, and quick resetting for a return to operation, thereby minimizing downtime and steadily boosting overall production capacity.
