III. Product Structure
The pneumatic clutch brake is composed of essential components, which include:
- Clutch Body: Positioned on the equipment's main shaft, its central hole size can be customized per customer specifications (refer to the sample for size range), serving as the clutch's central component.
- Clutch Ear Plate and Brake Ear Plate: These vital components are ingeniously connected to the flywheel and machine body of the equipment through four meticulously placed pins. This robust connection guarantees the stable and efficient operation of both the clutch and brake systems, ensuring seamless performance.
- Friction Pads (Blocks): These essential elements are the heart of the clutching and braking process, expertly facilitating the smooth transmission and precise interruption of power, enhancing the overall functionality and responsiveness of the system.
- Clutch Pins, Brake Pins, and Locking Plates: These components serve as the indispensable connectors and fixers for various parts. Notably, the locking plates are skillfully embedded in the pin grooves and securely fixed on the flywheel or machine body with screws, effectively preventing any unwanted axial movement of the pins, thereby solidifying the structural integrity.


IV. Working Principle
(I) Clutching Process
The clutching process begins as external compressed air gracefully enters the clutch cylinder through the intake hole, prompting the piston to move with precision. This movement, transmitted through the friction pads, clutch body, and flat key, elegantly rotates the driven part, achieving flawless clutch engagement and enabling the seamless transmission of power.

(II) Braking Process
With the cessation of air supply, the piston adeptly reverses direction under the influence of a spring. Working in concert with the friction pads, clutch body, and flat key, it efficiently brakes the driven part with remarkable speed. This swift braking action, completing in just 0.01 - 0.02 seconds, ensures the equipment can halt promptly and safely.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For optimal installation accuracy and stability of the pins, the hole tolerance must be H7. Additionally, the center of the hole should be meticulously parallel to the main shaft center, ensuring impeccable alignment and performance.

(II) Geometric Tolerance and Roughness Requirements
Adherence to national standards for geometric tolerance and roughness of the center hole and keyway is imperative. Similarly, the customer's main shaft should meet these exacting requirements, significantly enhancing product performance and reliability.

(III) Installation Sequence Suggestions
For installation flexibility, customers may choose the sequence that best suits their circumstances. Generally, it is advisable to first install the clutch and brake ear plates, along with the pins and locking plates, followed by the clutch brake body, for a seamless assembly process.

(IV) Installation Notes for Square Pins
Square pins play a critical role in mitigating installation size errors between the two pins and addressing plate thermal deformation due to clutch heating. It is crucial to ensure that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate, maintaining optimal alignment and functionality.

(V) Sealing Requirements for Axial Air Intake
For systems with axial air intake, it is essential to install sealing caps at both ends of the clutch. This prevents any potential gas leakage, thereby maintaining operational integrity and efficiency.

(VI) Check after Installation
Upon installation completion, it is vital to ensure that both the clutch end and brake end move freely. This guarantees the normal and efficient operation of the clutch and brake, safeguarding performance reliability and safety.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch we offer has been meticulously inspected to ensure top-notch quality and performance. Unauthorized disassembly voids any responsibility for damage on our part. Spot a quality issue? Notify us promptly, and we'll swiftly address it, ensuring your satisfaction and uninterrupted operation.

(II) Friction Pad Replacement Method
Friction pads are essential yet consumable components. When they show significant wear from extensive use, it's time for a replacement. Our design simplifies this process, negating the need for disassembly of the ear plates and clutch, streamlining your maintenance tasks. Here's how you can do it:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Next, remove the securing bolts and nuts, swap out the worn friction pads with new ones, and then securely tighten the bolts and nuts again.
- Replacement with Air Supply: Start by loosening the brake ear plate and follow the previous steps to seamlessly replace with fresh friction pads.

(III) Timing for Friction Pad Replacement
- In machinery like presses, if it fails to achieve rated output, inspect whether the friction pads are due for replacement.
- When wear exceeds 50% of the pads' original thickness, it's essential to replace them promptly to maintain optimal functionality.

VII. Product Selection
Selecting the right clutch is pivotal as it plays a vital role in your equipment's functionality and performance.
- Consequences of Improper Selection: A clutch that is too small won't achieve the desired capacity, while an overly large one will inflate costs and cause overheating, expediting friction pad and sealing ring wear.
- Selection Suggestions: Utilize our comprehensive samples or consult with our expert technicians. We are poised to offer tailored guidance ensuring the ideal clutch match for your needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Never touch the fast-spinning clutch with hands or objects. This is critical to avoid serious hazards.

(II) Protection from High Temperature
Post-operation, the clutch remains hot. Avoid direct contact to prevent burns. Allow roughly 30 minutes for cooling before maintenance.

(III) Side Protection
Standing beside a rotating clutch poses risks from dislodged objects. Always use a protective cover to enhance safety.

(IV) Attention during Ventilation Operation
During air supply operations, refrain from touching the friction pads with your fingers to prevent getting pinched.

(V) Safety of Internal Structure
The clutch houses internal springs. Unauthorized disassembly can lead to injury. Always seek professional assistance for such tasks.
