III. Product Structure
The pneumatic clutch brake is composed of key components including:
- Clutch Body: Mounted on the equipment's main shaft, customizable center hole sizes (refer to sample size range) cater to customer requirements, serving as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: These pivotal components serve as the linchpins for seamless operation. Connected through four pins to the flywheel and machine body, they ensure the smooth and unwavering functionality of both the clutch and brake mechanisms.
- Friction Pads (Blocks): These essential elements are integral to the clutching and braking processes, deftly facilitating the powerful transmission and precise interruption of power, ensuring optimal performance.
- Clutch Pins, Brake Pins, and Locking Plates: These components are crucial for robustly connecting and securing various elements. The ingeniously designed locking plates fit snugly into the pin grooves and are securely affixed to the flywheel or body with screws, effectively preventing any unwanted axial movement.


IV. Working Principle
(I) Clutching Process
Embark on the clutching journey as external compressed air enters the clutch cylinder through the intake hole, propelling the piston into motion. The synergy between friction pads, clutch body, and flat key causes the driven part to rotate, realizing clutch engagement and the flawless transmission of power.

(II) Braking Process
Upon halting the air supply, the piston retracts under the spring's influence, swiftly engaging the friction pads, clutch body, and flat key to rapidly brake the driven part. This swift braking takes a mere 0.01 - 0.02 seconds, ensuring immediate cessation of equipment operation.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Precision is key with the hole tolerance for pin installation at H7. Ensuring that the hole center remains parallel to the main shaft center is vital for maintaining the installation precision and stability of these crucial pins.

(II) Geometric Tolerance and Roughness Requirements
Adherence to national standards for geometric tolerance and roughness of the center hole and keyway is essential. Equally, the geometric tolerance and roughness of the customer's main shaft must align with these standards to elevate overall product performance.

(III) Installation Sequence Suggestions
The installation sequence offers flexibility, allowing customization based on specific scenarios. Typically, the installation commences with clutch and brake ear plates, followed by pins, locking plates, and concludes with the clutch brake body for optimal setup.

(IV) Installation Notes for Square Pins
Square pins are meticulously designed to mitigate installation size variations of two pins and the thermal deformation of plates caused by clutch heating. Ensure that both flat surfaces of the square pin align parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
In cases of axial air intake, it is crucial to install sealing caps at both clutch ends to effectively thwart any potential gas leakage, ensuring airtight integrity.

(VI) Check after Installation
Post-installation checks are vital, ensuring that both the clutch end and brake end move effortlessly, which is essential for the smooth and reliable operation of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each expertly crafted clutch offered by Shandong Tenord Machinery Equipment Co., Ltd. has undergone rigorous quality checks to ensure peak performance. Customers are advised against unauthorized disassembly to prevent potential damage. Our company will not bear responsibility for any harm caused by private disassembly. Should you encounter any quality issues, please notify us promptly, and our dedicated team will address the matter with utmost urgency.

(II) Friction Pad Replacement Method
Friction pads are essential, yet consumable, components of the Kb3500 Air Brake for Durable Punching and Cutting Machines. They require replacement after extensive use when signs of significant wear appear. Our innovative design allows for a hassle-free replacement process that eliminates the need to disassemble ear plates or the clutch itself. The straightforward replacement steps are as follows:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed to remove the bolts and nuts securing the friction pads. Replace them with new pads, ensuring all bolts and nuts are securely tightened for optimal performance.
- Replacement with Air Supply: Loosen the brake ear plate and execute the same procedure to replace worn friction pads effectively.

(III) Timing for Friction Pad Replacement
- For vital machinery like presses, if performance does not meet the rated capacity, it may be time to inspect and possibly replace the friction pads.
- When the wear on the friction pads surpasses half of their original thickness, customers are advised to promptly replace them to maintain efficiency and safety.

VII. Product Selection
Selecting the right clutch is critical for the optimal performance of your equipment. Choose wisely to ensure long-lasting and efficient operation.
- Consequences of Improper Selection: An undersized clutch will fail to achieve the rated capacity, while an oversized one unnecessarily inflates costs and risks overheating, leading to accelerated wear and seal aging.
- Selection Suggestions: With Shandong Tenord Machinery Equipment Co., Ltd., you can confidently choose the perfect fit by utilizing our comprehensive samples or consulting with our expert technicians for tailored advice.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Avoid direct contact with the clutch during high-speed rotation to prevent injury. Stay safe by keeping hands and objects away from the operating mechanism.

(II) Protection from High Temperature
After operation, the clutch may remain hot. Avoid immediate contact to prevent burns. Allow approximately 30 minutes for the clutch to cool to a safe, ambient temperature before performing any maintenance.

(III) Side Protection
Maintain safety by not standing beside the rotating clutch to prevent accidents from potential debris. Installing protective covers is essential during operation for added security.

(IV) Attention during Ventilation Operation
During ventilation and air-stopping processes, keep fingers away from friction pads to avoid injury. Exercise caution at all times.

(V) Safety of Internal Structure
The internal springs of the clutch demand careful handling. Refrain from unauthorized disassembly. If necessary, entrust this task to our skilled professionals to ensure safety and integrity.
