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.

Impact of Size and Design on Cardan Coupling Performance and Durability

The size and design of a cardan coupling play a crucial role in determining its performance and durability across various applications:

  • Load Capacity: Larger and more robust cardan couplings are generally designed to handle higher torque and load capacities, making them suitable for heavy-duty applications.
  • Flexibility: The design of the coupling’s universal joint and its flexibility affect how well it can accommodate angular misalignment while maintaining smooth power transmission.
  • Alignment Tolerance: Well-designed cardan couplings have better alignment tolerances, allowing them to operate efficiently even in conditions with slight misalignment.
  • Materials: The choice of materials impacts the coupling’s strength, corrosion resistance, and overall durability, especially in harsh environments.
  • Bearing Arrangement: The bearing arrangement within the coupling affects its ability to withstand both axial and radial forces, which is crucial for stability.
  • Sealing: Effective sealing mechanisms prevent contaminants from entering the coupling, ensuring smooth operation and preventing premature wear.
  • Dynamic Balance: Proper dynamic balance reduces vibrations and stress on connected components, contributing to extended coupling life.
  • Lubrication: The design should allow for adequate lubrication, which is essential for reducing friction and wear.
  • Installation and Maintenance: A well-designed coupling should be easy to install and maintain, with accessible lubrication points and inspection areas.

Ultimately, the size and design of a cardan coupling should be carefully matched to the specific requirements of the application to ensure optimal performance, reliability, and longevity.

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.

Are there different types of cardan couplings for various applications?

Yes, there are different types of cardan couplings designed to suit various applications and requirements:

  • Single Universal Joint: This is the most common type of cardan coupling, consisting of two yokes connected by a cross-shaped center piece. It is suitable for applications where angular misalignment compensation is needed, but the shafts are not too far apart.
  • Double Cardan Joint: Also known as a double U-joint or CV joint, this type consists of two universal joints connected by an intermediate shaft. It is used when higher angles of misalignment need to be accommodated or when a constant velocity transmission is required.
  • Disc Type Coupling: This type uses flexible discs or plates to transmit torque and compensate for misalignment. It is often used in applications with limited space and moderate torque requirements.
  • Block Type Coupling: Block type cardan couplings use solid blocks or spheres to transmit torque. They are suitable for heavy-duty applications and can handle higher torque loads.
  • Floating Shaft Coupling: This design involves two shafts connected by a third floating shaft, which allows for even higher angles of misalignment and smoother torque transmission.
  • Needle Bearing Universal Joint: In this type, needle bearings are used to reduce friction and improve efficiency. It is often used in precision applications where low friction and high efficiency are crucial.

The choice of cardan coupling type depends on factors such as the amount of misalignment, torque requirements, available space, and the need for constant velocity transmission. Selecting the right type ensures optimal performance and longevity in various mechanical systems.
