(VI) Diverse Connection Methods
- Flexible Connection Options: Equipped with versatile connection methods that can be tailored to various site requirements, this product offers robust adaptability, ensuring seamless integration with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake is composed of key components including:
- Clutch Body: Mounted on the main shaft of the equipment, the center hole size is customizable to meet specific customer demands (size range as per sample), representing the core of the clutch system.
- Clutch Ear Plate and Brake Ear Plate: These are crucial components, intricately connected to the flywheel and machine body via four robust pins. This ensures a seamless and stable operation of both the clutch and brake systems, providing enhanced performance and reliability.
- Friction Pads (Blocks): These essential elements are at the heart of the clutching and braking processes. They play a vital role in enabling the smooth transmission and quick interruption of power, ensuring optimal functioning of your machinery.
- Clutch Pins, Brake Pins and Locking Plates: These components are meticulously designed for securing and connecting various parts. The locking plates are strategically embedded in the pin grooves and securely fixed on the flywheel or machine body with screws, effectively preventing any axial pin movement and enhancing overall operational stability.


IV. Working Principle
(I) Clutching Process
External compressed air is expertly channeled into the clutch cylinder through the intake hole, propelling the piston into action. This movement, facilitated by the friction pads, clutch body, and flat key, results in the driven part being rotated, thereby achieving seamless clutch engagement and power transmission.

(II) Braking Process
Upon halting the air supply, the piston efficiently retracts under spring force, swiftly engaging the friction pads, clutch body, and flat key. This action brings the driven part to a rapid halt in just 0.01 - 0.02 seconds, ensuring your equipment stops with remarkable speed and precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The precision of installation is paramount. Ensure that the hole tolerance for the four pins is H7, and that the hole center remains parallel to the main shaft center. This guarantees the highest accuracy and stability in pin installation, optimizing your machinery's performance.

(II) Geometric Tolerance and Roughness Requirements
Adhere strictly to national standards for the geometric tolerance and roughness of your center hole and keyway. It is equally critical that the geometric tolerance and roughness of the customer's main shaft conform to these standards to significantly elevate product performance.

(III) Installation Sequence Suggestions
We advise customers to select the installation sequence based on their specific situation. Generally, begin with the installation of the clutch and brake ear plates, followed by the pins and locking plates. Conclude with the installation of the clutch brake body for optimal results.

(IV) Installation Notes for Square Pins
Square pins play a pivotal role in eliminating installation size discrepancies and compensating for plate thermal deformation caused by clutch heating. Ensure that the two flat surfaces of the square pin are precisely parallel to the radial direction of the ear plate for flawless operation.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is crucial to install sealing caps at both ends of the clutch. This precautionary measure prevents gas leakage, maintaining the integrity and efficiency of your machinery.

(VI) Check after Installation
Post-installation, ensure that both the clutch end and brake end can move effortlessly and freely. This is vital for confirming the normal operation and long-term reliability of the clutch and brake systems.

Product Description

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch offered by Shandong Tenord Machinery Equipment Co., Ltd. undergoes rigorous quality assurance checks. We strongly advise against unauthorized disassembly of the clutch, as any damages resulting from such actions are not covered by our company's warranty. Should you encounter any quality issues, promptly inform us to ensure swift resolution.

(II) Friction Pad Replacement Method
The friction pads are essential consumables in our Efficient Clutch Brake Punching Machine for Mechanical Shear Projects. After extended use, timely replacement is necessary due to wear. Our innovative design allows for effortless replacement of the friction pads without the need to dismantle the ear plates or the clutch. Detailed procedures are as follows:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed to detach the bolts and nuts securing the worn friction pads, then substitute them with new ones. Finally, secure by tightening the bolts and nuts.
- Replacement with Air Supply: Initiate by loosening the brake ear plate and carry out the above steps to ensure seamless replacement with new friction pads.

(III) Timing for Friction Pad Replacement
- In machinery like presses, if the performance does not meet the expected capacity, inspect the condition of the friction pads to determine if they require replacement.
- Replace the friction pads promptly when wear exceeds 50% of their original thickness, ensuring optimal performance and safety.

VII. Product Selection
Selecting the right clutch is pivotal for optimal performance of your equipment. It's vital to make the right choice based on your specific application needs.
- Consequences of Improper Selection: Choosing a clutch that's too small compromises operational capacity, whereas an excessively large clutch can escalate costs and lead to overheating. This will accelerate friction pad wear and expedite sealing ring degradation.
- Selection Suggestions: We recommend selecting from our comprehensive range of samples or consulting with our technical experts for professional guidance tailored to your needs, ensuring a perfect fit for your machinery.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, avoid making contact with the clutch or any object while it is in high-speed rotation to prevent hazardous situations.

(II) Protection from High Temperature
Avoid touching the clutch immediately after it halts to prevent burns. Allow approximately 30 minutes for the clutch to cool to ambient temperature before performing any maintenance tasks.

(III) Side Protection
Standing beside the rotating clutch is strictly prohibited to prevent accidents from any potential flying debris. Always ensure a protective cover is securely in place over the clutch during operation.

(IV) Attention during Ventilation Operation
During ventilation or air-stopping procedures, keep fingers away from the friction pads to avoid injury.

(V) Safety of Internal Structure
The clutch contains internal springs, and unauthorized disassembly may result in injury. Any required disassembly should only be performed by qualified professionals to ensure safety.
