(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with multiple connection methods, it's tailored for diverse site requirements. Its adaptability ensures perfect compatibility with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake is composed of essential components such as:
- Clutch Body: Mounted on the equipment's main shaft, its center hole size can be customized to meet specific customer requirements (refer to the sample for size range). This is the clutch's vital core component.
- Clutch Ear Plate and Brake Ear Plate: These pivotal components are ingeniously connected to the flywheel and machine body of the equipment via four robust pins, guaranteeing stable and efficient operation of the clutch and brake systems.
- Friction Pads (Blocks): The unsung heroes of the mechanism, these pads are instrumental in the clutching and braking process, seamlessly managing the transmission and interruption of power with precision.
- Clutch Pins, Brake Pins and Locking Plates: These essential connectors and fixers integrate various components flawlessly. Notably, the locking plates are securely embedded in the pin grooves and fastened on the flywheel or machine body with screws to prevent any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
When external compressed air enters the clutch cylinder through the intake hole, it propels the piston forward. This motion, through the dynamic interaction of friction pads, the clutch body, and the flat key, rotates the driven part, achieving clutch engagement and facilitating power transmission with ease.

(II) Braking Process
Upon ceasing the air supply, the piston reverses direction under the spring's influence. This swift action, coupled with the friction pads, clutch body, and flat key, ensures rapid braking of the driven part. The equipment stops swiftly within 0.01 - 0.02 seconds, showcasing exceptional braking precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For precision installation, the tolerance of the holes for the four pins should be H7, with the hole centers perfectly parallel to the main shaft center, ensuring impeccable installation accuracy and stability.

(II) Geometric Tolerance and Roughness Requirements
Adherence to national standards for geometric tolerance and roughness of the center hole and keyway is crucial. Similarly, the customer's main shaft must meet specified requirements, enhancing the product's overall performance.

(III) Installation Sequence Suggestions
Depending on the specific situation, customers have the flexibility to choose the installation sequence. Generally, it is advisable to start with the clutch and brake ear plates, pins, and locking plates, followed by the installation of the clutch brake body.

(IV) Installation Notes for Square Pins
To mitigate installation size errors of two pins and thermal deformation of the plate due to clutch heating, square pins are used. Ensure the two flat surfaces of the square pin are parallel to the radial direction of the ear plate for optimal performance.

(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 prevent any gas leakage.

(VI) Check after Installation
Post-installation, ensure the clutch end and brake end move freely, confirming the seamless and efficient operation of the clutch and brake system.

Product Description

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch crafted by Shandong Tenord Machinery Equipment Co., Ltd. is rigorously tested to ensure top-notch quality. Customers are advised against any unauthorized disassembly of the clutch. Should any damage arise from private tampering, our company will not be held accountable. In the event of any quality concerns, please notify us promptly, and we will address the issue with utmost urgency.

(II) Friction Pad Replacement Method
The friction pads on our Clutch Brake Punching Machine with Eccentric Press Functionality are designed as consumable parts meant for easy replacement once they display significant wear after prolonged use. Replacement of these pads is straightforward, with no need to disassemble ear plates or the clutch itself. The specific procedures are as follows:
- Replacement without Air Supply: To begin, loosen the ear plate of the clutch, then proceed to remove the bolts and nuts that secure the worn friction pads. Replace them with new ones, ensuring all bolts and nuts are firmly tightened.
- Replacement with Air Supply: Start by loosening the brake ear plate and follow the aforementioned steps to seamlessly replace the worn friction pads with new ones.

(III) Timing for Friction Pad Replacement
- In equipment like presses, if the machine struggles to achieve the rated capacity, it is a clear indicator to inspect the friction pads for potential replacement.
- When the wear on your friction pads surpasses half their original thickness, it is imperative for customers to promptly replace them to maintain optimal performance.

VII. Product Selection
Selecting the right clutch for your equipment is essential to its functionality and efficiency.
- Consequences of Improper Selection: A clutch that's too small will fail to meet the equipment's rated capacity. Conversely, an oversized clutch will unnecessarily inflate equipment costs and may lead to overheating, hastening the wear of friction pads and the degradation of sealing rings.
- Selection Suggestions: Customers can confidently choose from our comprehensive range of samples or directly consult with our skilled technicians for personalized selection advice. Our expert guidance ensures you receive the most compatible and efficient clutch solution.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
It is crucial to avoid any contact with the clutch using hands or objects when it is in high-speed rotation, to prevent serious injury or accidents.

(II) Protection from High Temperature
Avoid immediate contact with the clutch right after it stops rotating, as this could result in burns due to high temperatures. It is recommended to allow a cooling period of approximately 30 minutes until the clutch returns to room temperature before proceeding with any maintenance tasks.

(III) Side Protection
Standing beside a rotating clutch is strictly prohibited to minimize the risk of accidents from potential flying debris. Always ensure a protective cover is installed to enhance safety during clutch operation.

(IV) Attention during Ventilation Operation
During ventilation and air-stopping processes, it is strictly prohibited to touch the friction pads with your fingers to avoid injury.

(V) Safety of Internal Structure
The internal structure of the clutch includes delicate springs. Unauthorized disassembly is strictly discouraged to prevent injury. Should disassembly be necessary, it must be performed by qualified professionals.
