Product Description

FCL Rubber Bush, FCL Metal Pin, FCL Metal Coupling (3A2006)
 

Description: the polyurethane elastomeric is a new material of polymer synthetic between rubber and plastic. It has both high strength of plastic and high elasticity of rubber. Its characteristics are: 1, a wide range of hardness. It still has rubber elongation and resilience at high hardness. The polyurethane elastomeric has a hardness range of Shore A10-D80. 2. high strength. At rubber hardness, the tensile strength, tear strength and load carrying capacity are much higher than general rubber material. At high hardness, its impact strength and flexural strength are much higher than plastic material. 3, wear-resistant. Its wear resistance is very outstanding, generally in the range of 0.01-0.10cm3/1.61km, about 3-5 times than rubber material. 4, oil resistant. The polyurethane elastomeric is a highly CHINAMFG polymer compound which has low affinity with non-polar mineral oil and is hardly eroded in fuel oil and mechanical oil. 5, good resistance to oxygen and ozone. 6, excellent vibration absorption performance, can do damping and buffering. In the mold manufacturing industry, it replaces rubber and springs.7, has good low temperature performance. 8, radiation resistance. Polyurethane is highly resistant to high energy radiation and has satisfactory performance at 10-10 deg radiation dose. 9, with good machining performance.

Maintaining and Preserving Rubber Coupling Performance

To ensure the longevity and optimal performance of rubber couplings, the following best practices should be observed:

  • Regular Inspections: Perform visual inspections for signs of wear, cracks, or damage.
  • Lubrication: Apply appropriate lubricants to minimize friction and extend rubber life.
  • Alignment: Maintain proper alignment between connected shafts to prevent undue stress on the coupling.
  • Temperature Control: Monitor operating temperatures to prevent overheating that can accelerate rubber degradation.
  • Load Monitoring: Avoid overloading the coupling beyond its rated capacity.
  • Vibration Analysis: Monitor vibration levels and address excessive vibrations promptly.
  • Regular Maintenance: Follow manufacturer’s recommendations for maintenance schedules.
  • Replacement: Replace worn or damaged rubber elements as needed.

By adhering to these practices, the performance and service life of rubber couplings can be effectively preserved.

Signs of Wear or Deterioration in Rubber Couplings

Rubber couplings can show signs of wear and deterioration over time due to factors like torque, temperature, and environmental conditions. To identify potential issues, watch out for the following signs:

  • Visible Cracks or Damage: Inspect the rubber element for visible cracks, tears, or physical damage. Such issues can weaken the coupling’s torque transmission and vibration damping capabilities.
  • Reduced Flexibility: Stiff or less flexible rubber indicates material degradation, which can impact the coupling’s ability to accommodate misalignment and absorb vibrations.
  • Increased Vibrations: Excessive machinery vibrations may suggest worn-out rubber couplings. Deterioration of the rubber diminishes its vibration dampening properties.
  • Unusual Noises: Any unusual sounds like squeaking or knocking might point to improper rubber coupling function and the need for inspection.
  • Altered Performance: Decline in machinery performance, such as reduced torque transmission or higher energy consumption, can indicate coupling wear.

Regular inspections, visual checks, vibration analysis, and performance monitoring can help detect wear and deterioration early. This enables timely replacement and avoids operational problems.

Transmitting Torque and Damping Vibrations with a Rubber Coupling

A rubber coupling utilizes its flexible rubber element to achieve both torque transmission and vibration damping:

1. Torque Transmission: The rubber element connects two hubs, which are attached to the input and output shafts. As the input shaft rotates, it causes the rubber element to deform due to the applied torque. This deformation creates a shearing action within the rubber material, transmitting torque from the input to the output shaft.

2. Vibration Damping: The flexible rubber element of the coupling acts as a vibration isolator. When the coupling experiences external vibrations or shocks, the rubber absorbs the energy and dampens the vibrations before they reach the output shaft. The rubber’s elasticity and damping properties help mitigate vibrations and reduce the impact on the connected machinery, enhancing overall system performance and longevity.

This combination of torque transmission and vibration damping makes rubber couplings suitable for applications where misalignment compensation, shock absorption, and dampening of vibrations are essential, such as in pumps, compressors, HVAC systems, and various industrial machinery.
