It has garnered substantial acclaim, particularly in metal processing, paper processing machinery, woodworking machinery, and fiber machinery industries.II. Product Advantages(I) Compact Structure- Small Axial Size and Light Weight: Featuring a minimal axial size and lightweight construction, our product boasts low inherent rotational inertia. This efficiently minimizes the overall volume and weight while ensuring peak performance, thereby enhancing operational efficiency.(II) Safe and Reliable- Asbestos-free Friction Material: Our friction material is free from asbestos components, thereby eliminating potential health risks associated with asbestos and aligning with contemporary environmental and safety standards, offering users a secure and dependable experience.(III) Easy Maintenance- Simple Friction Pad Replacement: The straightforward replacement of friction pads does not necessitate disassembling the clutch, significantly cutting down on maintenance expenses and time, enhancing equipment maintenance efficiency, and reducing operational downtime.(IV) Excellent Heat Dissipation Performance- Unique Disc Arc Design: The innovative disc arc design vastly amplifies the product's heat dissipation capabilities, effectively lowering operational temperatures, prolonging the product's lifespan, and ensuring stability during prolonged high-load operations.(V) Quick Response- Fast Clutching and Braking: With a swift response time, it adeptly executes clutching and braking functions, fulfilling the urgent response requirements of various mechanical equipment and bolstering production efficiency.(VI) Diverse Connection Methods- Flexible Connection Options: Featuring a variety of connection methods, it is adaptable to different site requirements, offering strong versatility and perfect compatibility with diverse equipment.III. Product StructureThe pneumatic clutch brake is primarily composed of the following elements:- Clutch Body: Mounted on the equipment's main shaft, the center hole size is customizable to client specifications (size range available in sample), serving as the clutch's pivotal component.- Clutch Ear Plate and Brake Ear Plate: Ingeniously connected to the flywheel and machine body of the equipment, these components utilize four precision pins to guarantee unwavering stability and flawless operation of both the clutch and brake systems.- Friction Pads (Blocks): These vital components are at the heart of the clutching and braking processes, expertly facilitating the seamless transmission and interruption of power, ensuring precision and efficiency.- Clutch Pins, Brake Pins and Locking Plates: These crucial elements meticulously connect and secure the machine's components. The innovative locking plates are ingeniously embedded into pin grooves and fastened to the flywheel or machine body with screws, effectively preventing any undesired axial movement of the pins.IV. Working Principle(I) Clutching ProcessIn the clutching process, external compressed air is directed into the clutch cylinder through the intake hole, causing the piston to move. This dynamic action, in conjunction with friction pads, the clutch body, and a flat key, rotates the driven part, thereby achieving clutch engagement and smooth transmission of power.(II) Braking ProcessDuring the braking process, once the air supply is halted, the piston is propelled in the opposite direction by the spring's force. Through interaction with friction pads, the clutch body, and a flat key, the driven part is rapidly brought to a halt. With a remarkable braking time of just 0.01 - 0.02 seconds, this ensures the equipment's swift and effective stopping capability.V. Installation Requirements(I) Hole Diameter and Parallelism RequirementsThe installation of the four pins demands precision, with a hole tolerance of H7. Ensuring that the hole center remains parallel to the main shaft center is crucial for achieving unparalleled installation accuracy and stability of the pins.(II) Geometric Tolerance and Roughness RequirementsMeeting stringent national standards, the geometric tolerance and roughness of the center hole and keyway are critical. Equally, the customer's main shaft must adhere to these rigorous standards, significantly enhancing product performance and reliability.(III) Installation Sequence SuggestionsCustomers are encouraged to adapt the installation sequence to specific conditions. Typically, the installation begins with the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body, ensuring a methodical and efficient setup.(IV) Installation Notes for Square PinsSquare pins serve an essential role in mitigating installation size discrepancies of the two pins and countering plate thermal deformation due to clutch heating. Carefully ensure that the two flat surfaces of the square pin are precisely aligned parallel to the radial direction of the ear plate.(V) Sealing Requirements for Axial Air IntakeFor setups with axial air intake, it is imperative to install sealing caps at both ends of the clutch. This precautionary measure prevents any gas leakage, maintaining optimal operational integrity.(VI) Check after InstallationPost-installation, ensure that both the clutch end and brake end move freely. This is vital for verifying the flawless and normal operation of the clutch and brake systems, thereby guaranteeing outstanding performance.Product DescriptionVI. Product Maintenance(I) Professional Maintenance SuggestionsEvery clutch from Shandong Tenord Machinery Equipment Co., Ltd. undergoes rigorous quality assurance. Please refrain from unauthorized disassembly of the clutch, as any resultant damage will not be covered under our responsibility. Should you encounter any quality issues, report them immediately, and we pledge to address them swiftly.(II) Friction Pad Replacement MethodThe friction pads are wear-and-tear components that need replacement after extensive use when they become significantly worn. Our design ensures an uncomplicated replacement process without the need to dismantle ear plates and the clutch. Follow these methods:- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the bolts and nuts securing the friction pads, swap in the new pads, and securely fasten the bolts and nuts again.- Replacement with Air Supply: For air-supplied equipment, loosen the brake ear plate and replicate the steps above to replace the pads efficiently.(III) Timing for Friction Pad Replacement- For devices like presses, if the machine fails to achieve its rated capacity, inspect to determine if the friction pads require replacement.- When wear on the friction pads exceeds 50% of their original thickness, it is imperative to replace them promptly to ensure optimal performance.VII. Product SelectionChoosing the right clutch is vital for the functionality of your equipment.- Consequences of Improper Selection: A clutch that is too small won't meet capacity demands; an oversized clutch raises costs and risks overheating, accelerating both friction pad and sealing ring wear.- Selection Suggestions: Rely on our product samples or consult with our expert technicians for tailored advice, ensuring you select the ideal clutch for your requirements.VIII. Safety Precautions(I) Protection during High-speed RotationAvoid contact with the clutch or nearby objects during high-speed rotation to prevent hazards.(II) Protection from High TemperatureDo not touch the clutch immediately after cessation of activity due to heat risks. Allow the clutch to cool for approximately thirty minutes before undertaking maintenance.(III) Side ProtectionTo mitigate risks from any ejected objects, avoid positioning yourself sideways to the rotating clutch. Ensure a protective cover is securely in place during operation.(IV) Attention during Ventilation OperationDuring ventilation or air cessation, avoid contact with friction pads to prevent injury from pinching.(V) Safety of Internal StructureEquipped with internal springs, the clutch should never be disassembled by unauthorized individuals. Only qualified professionals should undertake disassembly to ensure safety.bbd19337
