Product Description

Our stainless 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

Applications of Tooth Couplings in Various Industries

Tooth couplings find widespread use in a variety of industries and applications that require efficient torque transmission and the ability to accommodate misalignment. Some common examples include:

• Industrial Machinery: Tooth couplings are frequently used in industrial machinery such as conveyors, mixers, pumps, and compressors. These applications often involve heavy loads and varying operating conditions where reliable torque transmission is essential.
• Automotive: In automotive applications, tooth couplings can be found in drivetrain systems, power transmission, and other components that require efficient torque transfer between rotating shafts.
• Marine: Tooth couplings are utilized in marine propulsion systems, where they help transmit torque from engines to propellers, ensuring smooth and reliable operation of vessels.
• Energy Generation: Power plants, including those for electricity generation and renewable energy sources, use tooth couplings in various equipment like turbines and generators to transfer rotational energy.
• Material Handling: Tooth couplings play a role in material handling equipment such as cranes, hoists, and elevators, where they assist in moving and lifting heavy loads.
• Mining and Construction: Industries like mining and construction rely on tooth couplings for equipment such as excavators, loaders, and crushers, which require robust torque transmission capabilities.

These examples illustrate the versatility of tooth couplings across different sectors where dependable torque transmission and misalignment compensation are vital for operational efficiency and reliability.

Suitability of Tooth Couplings for High-Speed Rotation and Heavy Loads

Yes, tooth couplings are well-suited for applications that involve high-speed rotation and heavy loads. Here’s why:

High-Speed Rotation: Tooth couplings are designed to transmit torque efficiently even at high rotational speeds. The tooth engagement provides a reliable means of torque transmission without slippage, making them ideal for high-speed applications.

Heavy Loads: Tooth couplings are robust and capable of handling substantial loads due to the interlocking teeth design. The teeth provide a secure connection that can transmit high levels of torque without deformation or damage.

Accuracy and Precision: Tooth couplings offer precise and accurate torque transmission, making them suitable for applications where precise positioning or synchronization is essential.

Minimal Backlash: Tooth couplings generally have minimal backlash due to the tight meshing of teeth. This reduces the play between the connected shafts, ensuring consistent motion and accurate positioning.

Sturdiness: Tooth couplings are manufactured from durable materials, making them capable of withstanding the stresses and forces associated with heavy loads and high speeds.

Customization: Tooth couplings can be tailored to specific applications by adjusting parameters such as tooth profile, size, and materials. This allows engineers to optimize the coupling’s performance for the intended use.

Advanced Designs: Modern tooth coupling designs incorporate advanced engineering techniques, such as finite element analysis, to ensure optimal performance even under challenging conditions.

Overall, tooth couplings offer a reliable solution for applications that demand both high-speed rotation and the ability to handle heavy loads effectively.

Types of Tooth Couplings for Specific Uses

There are various types of tooth couplings designed to cater to specific application requirements:

• Spur Tooth Couplings: These are the most common type, with straight teeth that transmit torque and handle misalignment.
• Helical Tooth Couplings: Helical teeth reduce noise, vibrations, and backlash while providing smooth torque transmission.
• Bevel Tooth Couplings: Ideal for applications where shafts intersect at an angle, such as in right-angle drives.
• Internal Tooth Couplings: Suitable for applications where space is limited and torque needs to be transmitted through the inside of the coupling.
• Sliding Tooth Couplings: These allow axial movement between shafts while transmitting torque, making them useful in applications with varying distances.
• Flexible Tooth Couplings: These accommodate misalignment and dampen vibrations, commonly used in pumps, compressors, and turbines.

The choice of tooth coupling type depends on factors like torque requirements, misalignment, space constraints, and specific application demands.
