Product Description

1.Small radial dimension and large bearing capacity are commonly used in shafting transmission under low speed and heavy load conditions.
2.It can compensate the relative offset of 2 axes in a certain angle and work long distance with the middle axle.
3.It is suitable for connecting horizontal 2 coaxial axes and driving shafting with a certain angle displaceme
Drum gear coupling, drum tooth is the external teeth made into a spherical, spherical center in the gear axis, side clearance than the general gear. The drum gear coupling can allow a larger angular displacement than the straight gear coupling. Moreover, the contact condition of the teeth is improved, so that the ability of transmitting torque is improved, and the service life of the coupling is prolonged. If the drum gear coupling to ensure safe and reliable work, good lubrication is essential, in exchange for slow wear. The high-speed drum-type gear coupling is mostly lubricated by lubricating oil, which needs to be filtered by high-precision oil filter, the filtrate is less than 10 microns, and the tooth surface requires continuous lubrication, otherwise the tooth surface temperature will increase and will accumulate moisture and dirt. Some high-speed drum-shaped gear couplings sometimes use the structure of oil-collecting groove hole, that is, the oil-collecting groove is processed in the outer gear shaft hole, and the oil hole which is communicated with the oil-collecting groove is drilled at the bottom of the outer gear groove, in order to make it fully lubricated, we rely on the drum-type tooth coupling high-speed operation of the centrifugal force, will be injected into the internal and external teeth mesh. Under the condition of angular displacement and stress concentration, the contact condition of the inner and outer teeth is improved by extrusion of the edge of the straight tooth, so that the friction and wear of the tooth surface are reduced and the noise is reduced. Under the same conditions, the load-carrying capacity of the drum-type gear coupling is increased by 15 -20% on average compared with the straight-type gear coupling in terms of the outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling.

Maintenance Practices for Ensuring Cardan Coupling Reliability

To ensure the reliability of cardan couplings, the following maintenance practices are crucial:

  • Lubrication: Regularly inspect and maintain the lubrication system. Ensure proper lubricant levels and use lubricants recommended by the manufacturer.
  • Alignment: Maintain proper alignment between the input and output shafts. Misalignment can lead to premature wear and reduced efficiency.
  • Regular Inspections: Perform visual inspections to detect signs of wear, damage, or corrosion. Regular inspections can help identify issues before they become major problems.
  • Monitoring: Use sensors and monitoring systems to track the performance of the cardan coupling. Monitor temperature, vibration, and other parameters for anomalies.
  • Torque Analysis: Analyze the torque requirements of the machinery system to ensure that the cardan coupling can handle the load without exceeding its limits.
  • Periodic Maintenance: Follow the manufacturer’s recommended maintenance schedule. This may include replacing worn components, lubricant changes, and alignment adjustments.
  • Record Keeping: Maintain detailed maintenance records, including inspection dates, lubrication schedules, and any repairs performed.
  • Training: Ensure that maintenance personnel are trained to properly inspect, maintain, and troubleshoot cardan couplings.

By implementing these maintenance practices, operators can extend the lifespan of cardan couplings, prevent unexpected failures, and optimize the performance of machinery systems.

Handling High Torque and Axial Displacement with Cardan Couplings

Cardan couplings, also known as universal joints or u-joints, are designed to transmit torque between two shafts that are not in a straight line. They are versatile components commonly used in various applications, including those requiring high torque and axial displacement.

Handling High Torque: Cardan couplings are capable of handling high levels of torque transmission due to their robust design and construction. The design allows for torque to be transmitted through a series of interconnected components, including the cross-shaped yokes and the bearing assemblies. The use of high-strength materials and precision manufacturing techniques contributes to the coupling’s ability to transmit torque efficiently.

Handling Axial Displacement: While cardan couplings are primarily designed for accommodating angular misalignment, they can also handle a certain degree of axial displacement. Axial displacement refers to the movement of the connected shafts along their axis. However, the axial displacement capacity of a cardan coupling is limited compared to its ability to handle angular misalignment.

It’s important to note that excessive torque or axial displacement beyond the coupling’s design limits can lead to premature wear, increased vibrations, and reduced performance. Manufacturers provide specifications and guidelines for the maximum torque and axial displacement that a specific cardan coupling can handle. Engineers and designers should adhere to these specifications to ensure optimal performance and longevity of the coupling in their applications.

How do you properly install and maintain a cardan coupling in machinery?

Proper installation and maintenance of a cardan coupling are crucial to ensure its reliable performance and longevity:

  • Installation:
    • Align the shafts properly before connecting the coupling to minimize initial misalignment.
    • Ensure that the universal joints are in phase, meaning their yokes are in the same orientation to prevent uneven torque transmission.
    • Follow the manufacturer’s instructions for torque specifications while tightening bolts and fasteners to prevent overloading or loosening during operation.
    • Make sure the coupling is properly centered and balanced to avoid vibrations.
    • Check for any obstructions or interference that might affect the movement of the coupling.
  • Maintenance:
    • Regularly inspect the coupling for signs of wear, such as cracks, corrosion, or damaged components.
    • Monitor the alignment of the shafts to detect any misalignment that might occur over time.
    • Lubricate the universal joints and bearings as recommended by the manufacturer to reduce friction and wear.
    • Replace worn or damaged components promptly to prevent further deterioration and potential coupling failure.
    • Perform vibration analysis and balancing to ensure the coupling operates smoothly and doesn’t contribute to excessive vibrations in the machinery.
    • Regularly check for any signs of overheating, which might indicate inadequate lubrication or other issues.
    • Keep the coupling area clean from debris, dirt, and contaminants that could affect its performance.

By following proper installation procedures and conducting regular maintenance checks, you can maximize the efficiency and reliability of a cardan coupling in machinery.
