(VI) Diverse Connection Methods
- With a range of flexible connection options, this product adapts seamlessly to diverse site requirements, ensuring perfect compatibility with various equipment setups.


III. Product Structure
The pneumatic clutch brake is composed of the following essential components:
- Clutch Body: Mounted on the main shaft, with customizable center hole sizes to meet specific customer requirements (size reference available in the sample), this component is the heart of the clutch system.
- Clutch Ear Plate and Brake Ear Plate: These crucial components are meticulously connected to the flywheel and machine body of the equipment through four strategically placed pins. This design ensures the seamless and stable operation of both the clutch and brake, offering reliability and efficiency.
- Friction Pads (Blocks): A pivotal element in the clutching and braking process, these pads are essential for the seamless transmission and interruption of power, enhancing the overall performance of the machine.
- Clutch Pins, Brake Pins, and Locking Plates: These components are vital for securely connecting and fixing various parts of the machinery. The locking plates are expertly embedded within the pin grooves and are securely fastened to the flywheel or machine body with screws, effectively preventing any unwanted axial movement of the pins.


IV. Working Principle
(I) Clutching Process
In the clutching process, external compressed air is ingeniously channeled into the clutch cylinder via the intake hole, initiating the movement of the piston. This action, in concert with the friction pads, clutch body, and flat key, allows the driven part to engage in seamless rotation, thereby facilitating the transmission of power with precision and efficiency.

(II) Braking Process
Once the air supply halts, the piston adeptly moves in the reverse direction, propelled by the spring's force. Through the friction pads, clutch body, and flat key, the driven part is swiftly and effectively braked. Remarkably, the braking time ranges from just 0.01 to 0.02 seconds, ensuring rapid cessation and reliable performance of the equipment.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For optimal installation accuracy and stability, the hole tolerance for installing the four pins must adhere to the H7 standard. It's crucial that the hole center remains parallel to the main shaft center, guaranteeing robust and precise installation of the pins.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and surface roughness of both the center hole and keyway must stringently comply with national standards. Additionally, the geometric tolerance and roughness of the customer's main shaft should meet specific requirements to elevate product performance and ensure seamless operation.

(III) Installation Sequence Suggestions
Customers are given the flexibility to choose the installation sequence tailored to their specific circumstances. Generally, it is advisable to first install the clutch and brake ear plates, pins, and locking plates, followed by the installation of the clutch brake body for optimal assembly and performance.

(IV) Installation Notes for Square Pins
Square pins are ingeniously designed to rectify installation size errors of two pins and accommodate the thermal deformation of the plate caused by clutch heating. It's important to ensure that the two flat surfaces of the square pin are parallel to the radial direction of the ear plate, for precision and stability.

(V) Sealing Requirements for Axial Air Intake
In cases of axial air intake, it is imperative to install sealing caps at both ends of the clutch. This precaution effectively prevents gas leakage, ensuring the system's integrity and efficiency.

(VI) Check after Installation
Upon completing the installation, it is essential to verify that both the clutch end and brake end can move freely without any obstruction. This check is crucial to guarantee the normal and efficient operation of the clutch and brake.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each and every clutch offered by Shandong Tenord Machinery Equipment Co., Ltd. has passed rigorous quality checks. It is essential that customers refrain from unauthorized disassembly of the clutch unit. Any damages that result from such private disassembly are not covered by our warranty. Should you encounter any quality issues, please notify us promptly, and we will address them with utmost urgency and precision.

(II) Friction Pad Replacement Method
Our friction pads are designed as consumable components, necessitating timely replacement once extensive usage leads to notable wear. Fortunately, replacing the friction pads on our Versatile Clutch Brake Punching Machine is a straightforward process, requiring no dismantling of ear plates or clutch components. Here's how you can effortlessly achieve this:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the bolts and nuts securing the worn friction pads, replace them with new ones, and then torque the bolts and nuts to secure them firmly.
- Replacement with Air Supply: Follow the same steps as above by loosening the brake ear plate and proceed with the replacement of the friction pads.

(III) Timing for Friction Pad Replacement
- When operating equipment such as presses, should the machine fail to achieve its rated capacity, it is advisable to inspect whether the friction pads are due for replacement.
- It's crucial to replace friction pads when their wear surpasses fifty percent of their original thickness to ensure optimal performance and safety.

VII. Product Selection
Ensuring the right clutch selection is vital for the optimal functioning of your equipment.
- Consequences of Improper Selection: Selecting a clutch that is undersized may hinder the equipment's ability to meet its rated capacity. Conversely, an oversized clutch not only escalates equipment costs but also risks overheating, which can accelerate friction pad wear and seal ring degradation.
- Selection Suggestions: Customers are encouraged to consult our comprehensive samples or directly contact our expert technicians for personalized advice. We are committed to providing you with expert guidance for the ideal clutch selection.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To prevent hazardous situations, it is strictly prohibited to come into contact with the clutch or introduce any objects when it is spinning at high speeds.

(II) Protection from High Temperature
Direct contact with the clutch immediately after it ceases rotation is strictly forbidden to avoid burns. Allow approximately thirty minutes for the clutch to cool to ambient temperature before conducting any maintenance.

(III) Side Protection
Standing beside a rotating clutch is highly discouraged to prevent accidents from potential projectiles. It is advisable to install a protective cover over the clutch during operation.

(IV) Attention during Ventilation Operation
During ventilation and when stopping air supply, avoid touching the friction pads with fingers to prevent injury from pinching.

(V) Safety of Internal Structure
The clutch contains internal springs. Unauthorized disassembly should be strictly avoided to prevent injury. All disassembly procedures must be conducted by trained professionals.
