Product Advantages(I) Compact Structure- Efficiently Designed: The small axial size and lightweight construction reduce inherent rotational inertia, minimizing overall equipment volume and weight while maintaining performance. This enhancement boosts the operating efficiency of your machinery.(II) Safe and Reliable- Asbestos-Free Assurance: Utilizing friction materials free from asbestos, it aligns with modern environmental and safety standards, eliminating health risks and offering a safer, more reliable user experience.(III) Easy Maintenance- Simplified Upkeep: Friction pad replacement is straightforward, requiring no clutch disassembly, which significantly cuts down on maintenance costs and time, thereby heightening equipment maintenance efficiency and minimizing downtime.(IV) Excellent Heat Dissipation Performance- Advanced Heat Management: The product's unique disc arc design drastically enhances heat dissipation, reducing operational temperatures, extending service life, and ensuring equipment stability during prolonged, high-load operations.(V) Quick Response- Rapid Engagement: With swift clutching and braking capabilities, it meets the demands of mechanical equipment for quick responses, greatly enhancing production efficiency.(VI) Diverse Connection Methods- Versatile Connectivity: Equipped with various connection options, it adapts flexibly to diverse site requirements, ensuring seamless compatibility with a wide range of equipment.III. Product StructureThe pneumatic clutch brake is composed of several key elements:- Clutch Body: Positioned on the equipment's main shaft, the center hole size is customizable to client specifications (refer to sample for size range), serving as the clutch's pivotal component.- Clutch Ear Plate and Brake Ear Plate: These vital components are securely affixed to the flywheel and the machine's structure via four pins, maintaining the seamless and stable operation of both the clutch and brake systems.- Friction Pads (Blocks): These essential elements serve a pivotal role in the clutching and braking processes, facilitating the seamless transmission and precise interruption of power, ensuring optimal performance.- Clutch Pins, Brake Pins and Locking Plates: Designed to connect and secure various components, these elements are crucial. The locking plates are strategically embedded within pin grooves and firmly attached to the flywheel or machine body using screws, preventing any unwanted axial movement of the pins.IV. Working Principle(I) Clutching ProcessAs external compressed air flows into the clutch cylinder via the intake hole, it propels the piston into motion. This action, in conjunction with friction pads, the clutch body, and a flat key, rotates the driven part, achieving clutch engagement and enabling seamless power transmission.(II) Braking ProcessUpon halting the air supply, the piston swiftly retracts under the influence of a spring. This action, facilitated by the friction pads, clutch body, and flat key, effectively brakes the driven part. The braking time is remarkably swift, ranging from just 0.01 to 0.02 seconds, ensuring rapid cessation of operations.V. Installation Requirements(I) Hole Diameter and Parallelism RequirementsThe pin installation holes must adhere to an H7 tolerance, while the hole centers must align parallelly with the main shaft's center. This precision ensures the flawless and stable installation of the pins.(II) Geometric Tolerance and Roughness RequirementsBoth the geometric tolerance and roughness of the center hole and keyway are required to comply stringently with national standards. Similarly, the customer's main shaft should meet the requisite criteria, thereby enhancing product performance and reliability.(III) Installation Sequence SuggestionsCustomers are encouraged to select the installation sequence tailored to their specific needs. Typically, installing the clutch and brake ear plates, followed by pins and locking plates, before finally securing the clutch brake body, is advisable.(IV) Installation Notes for Square PinsSquare pins play a crucial role in mitigating installation size discrepancies of dual pins and counteract plate deformation due to clutch heating. It is imperative that the two flat surfaces of the square pin are aligned parallel to the radial direction of the ear plate.(V) Sealing Requirements for Axial Air IntakeFor axial air intake configurations, it is essential to install sealing caps at both ends of the clutch. This precautionary measure effectively prevents any potential gas leakage.(VI) Check after InstallationPost-installation, it is crucial to ensure that both the clutch end and brake end operate with unimpeded movement, guaranteeing the smooth and efficient functioning of the clutch and brake systems.Product DescriptionVI. Product Maintenance(I) Professional Maintenance SuggestionsAt Shandong Tenord Machinery Equipment Co., Ltd., we pride ourselves on the meticulous quality control of every clutch we produce. It is vital that customers refrain from private disassembly of the clutch, as this can lead to damages for which we cannot be held accountable. Should you encounter any quality concerns, do not hesitate to contact us promptly, and we will dedicate ourselves to resolving the issue swiftly and efficiently.(II) Friction Pad Replacement MethodOur friction pads, being consumable, need eventual replacement due to wear from extended use. Fortunately, our advanced design allows for easy replacement without the need to disassemble the ear plates or clutch. Follow these straightforward methods:- Replacement without Air Supply: Start by loosening the clutch ear plate. Proceed to remove the bolts and nuts securing the friction pads. Replace with new friction pads, and ensure all bolts and nuts are re-tightened securely.- Replacement with Air Supply: Simply loosen the brake ear plate and follow the same straightforward steps to refresh your friction pads.(III) Timing for Friction Pad Replacement- In scenarios involving equipment like presses, if the machine fails to reach its rated capacity, it's time to evaluate the condition of the friction pads.- Once the friction pads exhibit wear exceeding half of their original thickness, a timely replacement is crucial to maintain optimal performance.VII. Product SelectionChoosing the right clutch is paramount to ensuring the optimal function of your equipment. This decision directly impacts performance and longevity.- Consequences of Improper Selection: Selecting a clutch that's too small may not support the necessary capacity, while an excessively large clutch can lead to unnecessary costs and overheating, hastening the wear of friction pads and seal deterioration.- Selection Suggestions: Browse our detailed company samples or engage with our expert technicians for tailored advice. We are committed to guiding you in selecting the perfect clutch for your needs.VIII. Safety Precautions(I) Protection during High-speed RotationTo ensure safety, never attempt to touch the clutch with your hands or other objects while it is rotating at high speed, as this poses significant danger.(II) Protection from High TemperatureAvoid contact with the clutch immediately after it stops, as it retains heat which can cause burns. Allow approximately 30 minutes for it to cool down to room temperature before commencing any maintenance activities.(III) Side ProtectionStanding at the side of a rotating clutch is prohibited to prevent accidents from potential debris. Always equip the clutch with a protective cover during operations.(IV) Attention during Ventilation OperationDuring the process of ventilation and air-stopping, keep fingers clear of the friction pads to prevent pinching injuries.(V) Safety of Internal StructureThe internal springs of the clutch are crucial to its function; thus, refrain from unauthorized disassembly. If disassembly is essential, it must be conducted by qualified professionals to maintain safety.b025fa8a
