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.

Materials Used in Manufacturing Cardan Couplings
Cardan couplings, also known as universal joints or u-joints, are crucial components in mechanical systems that transmit torque and accommodate angular misalignment. These couplings are manufactured using a variety of materials to ensure durability, reliability, and performance. Common materials used in the manufacturing of cardan couplings include:
1. Steel: Steel is a widely used material due to its high strength, durability, and resistance to wear and corrosion. Alloy steels are often chosen for their enhanced mechanical properties and fatigue resistance.
2. Cast Iron: Cast iron is used in some cardan couplings, especially in older or heavier-duty applications. It provides good strength and vibration dampening properties.
3. Aluminum: Aluminum is chosen for its lightweight properties, making it suitable for applications where weight reduction is important. It is commonly used in industries such as automotive and aerospace.
4. Stainless Steel: Stainless steel is used when corrosion resistance is a critical factor. It is commonly employed in environments where the coupling may be exposed to moisture or corrosive substances.
5. Bronze: Bronze can be used in certain applications where self-lubricating properties are desired. It also provides good wear resistance.
6. Synthetic Polymers: Some modern cardan couplings use synthetic polymers or plastics in their construction to reduce weight and provide specific performance characteristics, such as dampening vibrations.
The choice of material depends on factors like the application requirements, operational conditions, torque transmission, operating speed, and environmental factors. Manufacturers select materials that offer the best combination of strength, durability, wear resistance, and corrosion resistance for the specific use case of the cardan coupling.
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.
