Deeply rooted in China's field of transmission protection components, Jiteng stands as an integrated manufacturer and one-stop supplier—handling both R&D and production—and is the independent developer and producer of the Multi-Friction Torque Limiter. This product is a slip-type mechanical overload protection component, currently representing the most versatile torque-limiting device on the market, capable of adapting to the widest range of operating conditions.
Unlike disengaging-type torque limiters—which completely cut off power immediately upon activation—the Multi-Friction Torque Limiter utilizes multiple sets of wear-resistant friction plates as its transmission medium. During normal operation, it relies on static friction to transmit torque stably. However, should issues arise—such as material jamming, instantaneous shock loads, or excessive load levels—relative sliding occurs between the friction surfaces. This mechanism absorbs the overload impact through a flexible slipping action, rather than abruptly halting the equipment.
The Multi-Friction Torque Limiter features an integrated, compact structural design with components arranged in a tight, orderly configuration. The overall assembly is free of unnecessary structural redundancy, thereby minimizing spatial footprint while facilitating subsequent disassembly, maintenance, and component replacement.
- Complete Set of Core Components: The entire assembly consists of eight primary components: a driving plate, a driven plate, wear-resistant friction plates, compression springs, a torque adjustment nut, locking and positioning elements, an adaptive bushing, and a dust-proof protective housing. Each component fulfills a specific function, working in synergy to execute both power transmission and overload protection tasks.
- Ease of Assembly and Adjustment: Thanks to a standardized, modular structural design with high component compatibility, operators do not require specialized assembly experience to quickly complete installation, alignment, and torque adjustment procedures.
- External Dust-Proof Housing: A dedicated dust-proof housing serves to isolate the internal mechanism from external dust and airborne impurities. This prevents particulate matter from adhering to the friction plate surfaces, thereby averting malfunctions such as slipping failures or transmission vibration, and ultimately extending the service life of the friction plates.
The core operational logic of the Multi-Friction Torque Limiter is based on the combination of spring pre-load pressure and a multi-plate friction structure. It operates across three distinct states—Normal Transmission, Overload Protection, and Automatic Reset—and is compatible with a variety of operational modes, including both continuous and intermittent duty cycles.
- Standard Power Transmission Mode: During normal operation under load, the compression springs continuously exert constant pressure, clamping the friction plates on both sides. Torque is transmitted via the static friction force between the plates, ensuring zero transmission backlash, minimal operational noise, and stable power transmission efficiency—making it ideal for continuous, long-duration operation.
- Overload Slip Protection Mode: When the equipment encounters abnormal conditions—such as material jamming or sudden shock loads—and the actual torque exceeds the preset protection threshold, relative sliding occurs between the friction contact surfaces. This "flexible slip" mode effectively buffers the impact of the overload, preventing harmful loads from propagating to downstream components (such as motors, spindles, and reducers), thereby preventing equipment damage at the source.
- Fully Automatic Reset Mode: Once personnel have diagnosed and cleared the overload fault—and the equipment load has returned to standard levels—the friction plates on both sides automatically re-engage and lock into place. No manual intervention or equipment disassembly is required; the transmission system instantly resumes normal operation, significantly reducing downtime.
- Conveyor Systems: Compatible with various material handling lines, chain conveyors, and bucket elevators; effectively resolves sudden overload issues caused by material accumulation or jamming.
- Woodworking & Packaging Equipment: Integrates with woodworking machinery and packaging/filling equipment to buffer transient shock loads generated during processing, thereby protecting precision transmission structures.
- General Fluid & Mixing Equipment: Suitable for use with mixing devices, industrial fans, and water pumps; ideal for transmission systems characterized by frequent load fluctuations and high start-stop cycles.
- Light Industrial Automation: Applicable to a wide range of small-to-medium-scale light industrial automation machinery; features a compact structure and ease of installation, perfectly meeting the safety protection requirements of small and medium-sized automated production lines.
Compared to gear-type, ball-type, or detent-type overload protection devices, the primary advantage of the Multi-Friction Torque Limiter lies in its lower total cost of ownership, making it the superior choice for large-volume equipment integration and demanding, high-frequency operational environments.
- Affordable Acquisition Cost: Featuring a simple overall structure and controllable component manufacturing costs, the unit offers exceptional value for money. This makes it an ideal choice for equipment manufacturers seeking cost-effective solutions for mass integration and bulk inventory stocking.
- Simple and Cost-Effective Maintenance: The assembly and disassembly process is simple and convenient; within the entire unit, only the friction discs are considered standard wear parts. Replacement tasks require no specialized precision tools and can be completed by a single person, significantly lowering the barriers to equipment maintenance and reducing labor costs.
- Reduced Overall Production Losses: Effectively prevents frequent equipment failures—such as shaft breakage, gear chipping, and motor burnout—thereby reducing component procurement costs while simultaneously minimizing downtime caused by malfunctions, ultimately boosting overall production efficiency.
- Exceptional Product Versatility: Our comprehensive product line features a full range of specifications and adheres to high industry standardization levels. Products of the same specifications are directly interchangeable with similar components currently available on the market, enabling companies to consolidate their spare parts inventory and simplify spare parts management.
As a mature domestic manufacturer of Multi-Friction Torque Limiters, our company has dedicated over a decade to specializing in the mechanical overload protection industry. Leveraging our proprietary production lines, we provide buyers both domestically and abroad with comprehensive transmission protection solutions characterized by high compatibility and low cost.
Every product—from raw forging and friction disc formulation to precision machining and final assembly—is manufactured entirely in-house. Each unit leaving our facility undergoes rigorous torque calibration and durability testing to ensure precise slip thresholds and stable operational performance.
We maintain a ready inventory of standard models (complete units) and spare friction discs. We are fully equipped to fulfill sample requests, small-batch orders, and full-container export orders, thereby significantly shortening delivery lead times for our overseas clients.
Our technical team analyzes factors such as equipment rotational speed, motor power, operating conditions, and installation space. By clearly distinguishing between slip-type and disengagement-type products, we match each client with the most suitable model and specifications, effectively preventing selection errors right from the initial planning stage.
We provide—free of charge—detailed product dimension drawings, installation tutorials, and torque adjustment parameter charts. For our overseas clients, we also offer remote video guidance for installation and commissioning, helping to resolve any operational challenges encountered on-site.
