This versatile product finds extensive application in sectors such as forging, printing, textile, welding, and shipbuilding. It has garnered exceptional acclaim, particularly in areas like metal processing, paper machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Lightweight: Boasting a compact axial size and reduced weight, with low rotational inertia, this design minimizes the equipment's overall volume and weight while ensuring optimal performance, thereby enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-Free Friction Material: The friction material is free of asbestos components, eliminating health hazards and meeting modern environmental and safety standards, offering users a safe and reliable experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Friction pad replacement is straightforward and doesn't require dismantling the clutch, significantly reducing maintenance costs and time, boosting maintenance efficiency, and minimizing downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: This innovative disc arc design dramatically enhances the product's heat dissipation capacity, effectively lowering operational temperatures, extending product lifespan, and ensuring stability during prolonged high-load operations.
(V) Quick Response
- Swift Clutching and Braking: Featuring rapid response capabilities, it swiftly executes clutching and braking functions, meeting the swift response demands of various machinery, thereby amplifying production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with multiple connection methods, it offers flexible customization to meet different site requirements, ensuring strong adaptability and seamless compatibility with assorted equipment.


III. Product Structure
The sophisticated pneumatic clutch brake comprises the following integral components:
- Clutch Body: Mounted on the equipment's main shaft, the center hole size is customizable per customer specifications (refer to the sample for size range), serving as the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: These essential components are ingeniously connected to the flywheel and machine body using four robust pins. This meticulous design ensures a seamless and stable operation for both the clutch and brake, promising optimal performance.
- Friction Pads (Blocks): These critical components are pivotal in the clutching and braking processes, skillfully facilitating the transmission and interruption of power with precision.
- Clutch Pins, Brake Pins, and Locking Plates: Expertly designed for secure connecting and fixing of various components, with locking plates embedded in pin grooves and firmly affixed to the flywheel or machine body. This design prevents axial movement, ensuring steadfast reliability.


IV. Working Principle
(I) Clutching Process
Upon the entry of external compressed air into the clutch cylinder through the ingeniously placed intake hole, the piston is propelled into motion. This action, through the friction pads, clutch body, and flat key, ensures the driven part rotates with precision, enabling seamless clutch engagement and power transmission.

(II) Braking Process
Once the air supply is halted, the piston is driven in reverse by the spring's action. This rapid motion, via the friction pads, clutch body, and flat key, swiftly brakes the driven part, stopping the machinery in an impressive time frame of just 0.01 - 0.02 seconds, guaranteeing immediate halt when needed.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Precision is paramount. The holes for the four pins must adhere to an H7 tolerance, maintaining parallel alignment with the main shaft center. This meticulous attention ensures the pins' installation accuracy and enduring stability.

(II) Geometric Tolerance and Roughness Requirements
Adherence to national standards for geometric tolerance and roughness is crucial for the center hole and keyway. Similarly, the customer's main shaft must meet these rigorous standards to elevate product performance.

(III) Installation Sequence Suggestions
Flexibility meets precision. Customers can adapt the installation sequence to their specific needs. Typically, it's recommended to first install clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins play a vital role in eliminating installation size errors and addressing thermal deformation from clutch heating. Ensure the two flat surfaces align parallel to the ear plate's radial direction for optimal performance.

(V) Sealing Requirements for Axial Air Intake
To prevent gas leakage in axial air intake systems, securely install sealing caps at both ends of the clutch. This simple step preserves system integrity.

(VI) Check after Installation
Post-installation, ensure that both the clutch and brake ends move freely to guarantee their smooth and reliable operation, safeguarding long-term functionality.

 

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Our clutches undergo stringent quality checks. Unauthorized disassembly voids responsibility for damages. Promptly report any quality issues for swift resolution-we're committed to your satisfaction.

(II) Friction Pad Replacement Method
Friction pads, vital yet consumable, should be replaced upon significant wear. Our design allows effortless replacement without disassembling ear plates and clutch, ensuring simplicity and convenience.
- Replacement without Air Supply: Loosen the clutch ear plate, carefully remove bolts and nuts securing the friction pads, replace with new pads, and firmly re-tighten the bolts and nuts.
- Replacement with Air Supply: Follow the same steps on the brake ear plate to efficiently replace with new friction pads, ensuring continued optimal performance.

(III) Timing for Friction Pad Replacement
- For equipment such as presses, ensuring optimal performance is key. If the machine fails to achieve its rated capacity, it's essential to inspect the friction pads for potential replacement needs.
- It's imperative to monitor the wear of the friction pads. Once the wear exceeds fifty percent of their original state, timely replacement by customers is critical to maintain efficiency.

VII. Product Selection
As a pivotal component of your machinery, selecting the right clutch is a decision of utmost importance.
- Consequences of Improper Selection: A clutch that's undersized won't meet capacity demands, while one that's oversized can lead to higher costs, excessive heat, expedited friction pad wear, and accelerated sealing ring degradation.
- Selection Suggestions: We offer a range of samples to guide your choice. Alternatively, consult our experienced technicians who are eager to provide expert advice tailored to your specific needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To ensure safety, refrain from any contact with the clutch during high-speed operation. This critical precaution helps prevent hazardous incidents.

(II) Protection from High Temperature
Post-operation, the clutch remains extremely hot. Avoid direct contact immediately after rotation ceases. Allow approximately 30 minutes for the temperature to normalize before engaging in any maintenance.

(III) Side Protection
For safety, never position yourself beside a rotating clutch due to the risk of flying debris. Utilizing a protective cover during operation is a vital safety measure.

(IV) Attention during Ventilation Operation
During ventilation processes, keeping fingers away from friction pads is paramount to avoid injury. Adhere strictly to this safety guideline.

(V) Safety of Internal Structure
Given the clutch's internal spring mechanism, unauthorized disassembly is strictly prohibited to prevent harm. Disassembly, if necessary, must be performed by qualified professionals only.
