III. Product Structure
The pneumatic clutch brake comprises several key components:
- Clutch Body: Mounted on the equipment's main shaft, the center hole size is customizable per client needs (refer to the sample for size range), serving as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: These crucial components are meticulously connected to the flywheel and machine body of the equipment respectively through four robust pins, guaranteeing the seamless and stable operation of both the clutch and brake systems.
- Friction Pads (Blocks): These essential elements play a pivotal role in both clutching and braking processes, effectively facilitating the transmission and interruption of power with precision and reliability.
- Clutch Pins, Brake Pins, and Locking Plates: Engineered for excellence, these components ensure the impeccable connection and fixation of various parts. The locking plates are skillfully embedded in the pin grooves and securely attached to the flywheel or machine body with screws to prevent any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air is introduced into the clutch cylinder via the intake hole, causing the piston to propel forward. This movement, through the friction pads, clutch body, and flat key, engages the driven part, thus enabling the flawless transmission of power.

(II) Braking Process
Upon discontinuing the air supply, the piston is compelled to move in the opposite direction under the spring's action. This process, mediated by the friction pads, clutch body, and flat key, effectuates a rapid brake. Remarkably, the braking duration is a mere 0.01 - 0.02 seconds, ensuring the equipment comes to a swift halt with unmatched efficiency.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation precision is paramount, with the hole tolerance for the four pins finely set to H7. Additionally, the hole center must be parallel to the main shaft center, securing the accuracy and steadfastness of the pin installation.

(II) Geometric Tolerance and Roughness Requirements
Adherence to strict national standards for the 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 meet these criteria, significantly enhancing product performance.

(III) Installation Sequence Suggestions
Customers are empowered to choose the installation sequence based on their unique requirements. Typically, it is advisable to first install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body, ensuring an efficient and orderly installation process.

(IV) Installation Notes for Square Pins
Square pins are integral in correcting installation size discrepancies between two pins and countering the thermal deformation of plates caused by clutch heating. It is crucial that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate for optimal functionality.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is imperative to install sealing caps at both ends of the clutch to effectively avert any potential gas leakage, ensuring sustained efficiency and safety.

(VI) Check after Installation
Post-installation, it is vital to verify that both the clutch end and brake end move freely, thereby ensuring the smooth and reliable operation of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch offered by Shandong Tenord Machinery Equipment Co., Ltd. has been rigorously tested and approved for quality assurance. Customers are strongly advised against unauthorized disassembly of the clutch as it can lead to damages for which the company holds no liability. Should you encounter any quality concerns, promptly notify us. We are committed to resolving any issues swiftly and efficiently.

(II) Friction Pad Replacement Method
The friction pads integral to our Kb1300 Air Clutch Brake are consumables that require replacement upon significant wear due to prolonged use. Our design facilitates an easy replacement process without necessitating the disassembly of the ear plates and clutch. The detailed procedure is outlined as follows:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed to remove the bolts and nuts securing the friction pads. After replacing with new pads, ensure all bolts and nuts are securely fastened.
- Replacement with Air Supply: Similar to the process above, start by loosening the brake ear plate, then replace the worn pads with new ones, ensuring all fittings are properly tightened.

(III) Timing for Friction Pad Replacement
- For machines such as mechanical shears, if they fail to achieve their rated capacity, it is imperative to check the condition of the friction pads for potential replacement.
- When the wear on the friction pads surpasses half of the new pad thickness, users must promptly replace the worn pads to ensure continued operational efficiency.

VII. Product Selection
As a pivotal part of your mechanical equipment, selecting the correct clutch is essential for optimal performance.
- Consequences of Improper Selection: An undersized clutch will fail to meet operational capacity, while an oversized one elevates costs and risks overheating, expediting the wear of friction pads and degradation of sealing rings.
- Selection Suggestions: Clients are encouraged to refer to our company's sample guidelines or consult our technical experts for tailored advice. We are dedicated to providing professional selection guidance to match your specific needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Under no circumstances should the clutch be touched by hands or objects during high-speed rotation to prevent any potential hazards.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after it ceases rotation to prevent burns. Allow approximately 30 minutes for the clutch to cool to room temperature before conducting any maintenance tasks.

(III) Side Protection
Standing beside a rotating clutch poses significant risk of injury from flying debris. Ensure a protective cover is utilized during operation to mitigate such hazards.

(IV) Attention during Ventilation Operation
During ventilation and air-cut operations, never touch the friction pads with your fingers to avoid injury.

(V) Safety of Internal Structure
Inside the clutch, springs are installed. Unauthorized disassembly poses a risk of injury. If disassembly is necessary, it should only be executed by trained professionals.
