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 Tooth Couplings
Common materials used in manufacturing tooth couplings include:
- Steel: Steel is a popular choice due to its high strength and durability. It can handle heavy loads and is suitable for a wide range of applications.
- Cast Iron: Cast iron is known for its excellent wear resistance and ability to dampen vibrations. It is often used in applications where shock absorption is important.
- Stainless Steel: Stainless steel is corrosion-resistant and can withstand harsh environments, making it suitable for industries like food processing and marine applications.
- Aluminum: Aluminum is lightweight and offers good corrosion resistance. It’s commonly used in applications where weight reduction is important.
- Bronze: Bronze is used for its self-lubricating properties and resistance to corrosion. It’s often employed in applications where lubrication is challenging.
The choice of material depends on factors such as the specific application, operating conditions, and required performance characteristics. Engineers select materials that offer the best combination of strength, durability, corrosion resistance, and other properties needed for the intended use of the tooth coupling.
Influence of Teeth Profiles and Spacing on Tooth Coupling Performance
The design of teeth profiles and spacing in tooth couplings significantly impacts their performance in various ways:
1. Torque Transmission: The shape of teeth profiles determines how efficiently torque is transmitted between the two shafts. Properly designed profiles maximize the surface contact area, enhancing torque transmission capabilities.
2. Load Distribution: The teeth profiles and spacing affect how loads are distributed across the coupling. Even distribution helps prevent localized stress concentrations and ensures uniform wear and longevity.
3. Misalignment Compensation: Tooth couplings with specific teeth profiles and spacing can better accommodate angular, radial, and axial misalignments between shafts. This reduces the risk of excessive wear and prolongs coupling life.
4. Backlash and Precision: The teeth spacing impacts the level of backlash, or play, between the teeth during rotation. Smaller teeth spacing reduces backlash, leading to more precise and accurate motion transmission.
5. Noise and Vibration: Well-designed teeth profiles and spacing can minimize noise and vibration during operation by promoting smoother engagement and disengagement of teeth.
6. Fatigue Resistance: Proper teeth profiles and spacing help distribute stresses evenly, enhancing the coupling’s fatigue resistance against cyclic loads.
7. Material Selection: Teeth profiles and spacing also influence the choice of materials for the coupling. Certain profiles may require specific materials to ensure durability and optimal performance.
8. Efficiency: Optimized teeth profiles and spacing reduce friction and wear, resulting in higher coupling efficiency and less energy loss.
9. Customization: The flexibility to customize teeth profiles and spacing allows engineers to tailor the coupling’s performance to the specific application requirements.
Overall, the design of teeth profiles and spacing is a critical factor in determining the overall efficiency, durability, precision, and performance of tooth couplings in various mechanical systems.
Proper Installation and Maintenance of Tooth Couplings
To ensure the proper function and longevity of a tooth coupling, follow these guidelines:
Installation:
- Ensure shafts are aligned within manufacturer specifications to prevent excessive loads on the coupling.
- Clean and inspect the coupling components before installation to avoid debris or contaminants.
- Use appropriate tools and methods to achieve proper fit between the coupling and the shafts.
- Follow the manufacturer’s instructions for tightening bolts or fasteners to the recommended torque.
Maintenance:
- Regularly inspect the coupling for signs of wear, such as tooth damage, corrosion, or misalignment.
- Check for any abnormal vibrations, noise, or overheating during operation, which could indicate coupling issues.
- Keep the coupling and surrounding area clean to prevent the accumulation of dirt or debris.
- Regularly lubricate the coupling as per the manufacturer’s recommendations to reduce friction and wear.
- Monitor the alignment of the connected equipment and address any misalignment promptly.
- Replace worn or damaged components promptly to avoid further damage and maintain coupling performance.
Following proper installation and maintenance practices will help maximize the efficiency and service life of the tooth coupling.
