Product Description

The steel couplings conform to all the mechanical requirement of DIN EN877/BS EN877. These couplings are composed of SS304 or SS 316 stainless steel shield, clamp assembly and EPDM(An elastomeric sealing sleeve that conform to the requirement of BS EN 681-1 and it also can resist the normal domestic effluents with thermal effects up to 70°C temperature). This elastomeric material was made by well balanced formula with the combination of outstanding properties in resisting abrasion, oil, grease, chemicals, ultraviolet, heat and cold conditions. This elastomeric sleeve also provides a cushioning element in the coupling to avoid shock, vibration and ensure a noiseless drainage system.
The stainless steel was selected for the clamp and shield assemblies because it possesses high corrosion resistance characteristics.
Our EN877 stainless steel coupling and grip collar are all produced using robots and fully automatic machinery. Not only do we have high production efficiency, but the quality of our products is very stable and reliable. It has been exported to many countries, such as Europe, Southeast Asia, Russia, etc. 
The standard that our products comply with:
1) DIN EN877; BS EN877;
2) EN 681-1:1996+A3:2005

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.
