Introduction to Tang Drive Coupling
1. Definition
A tang drive coupling is a type of flexible coupling that transmits torque between two shafts while allowing for misalignment and reducing vibration.
2. Structure
It consists of two hubs with internal teeth that engage with external teeth on a sleeve. The sleeve has tangs that fit into slots on the hubs, providing a secure connection.
3. Function
The tang drive coupling transmits power from one shaft to another while compensating for angular, parallel, and axial misalignments between the shafts.
4. Advantages
It offers high torque transmission capacity, easy installation and maintenance, vibration damping, and overload protection for connected equipment.
5. Applications
Tang drive couplings are commonly used in industrial machinery, pumps, compressors, and other rotating equipment that require smooth and reliable power transmission.
Types of Drive Couplings
1. Jaw Coupling
Jaw couplings are flexible couplings that transmit torque through elastomeric inserts, suitable for applications with moderate misalignment.
2. Gear Coupling
Gear couplings use gear teeth to transmit torque between shafts, ideal for high-speed and high-torque applications.
3. Grid Coupling
Grid couplings utilize a grid of metal strips to transmit torque, providing high torsional stiffness and damping characteristics.
4. Disc Coupling
Disc couplings use metal discs to transmit torque, offering high misalignment capacity and precision in demanding applications.
5. Oldham Coupling
Oldham couplings consist of three disks to transmit torque while allowing for axial misalignment, suitable for low torque applications.
Materials Used in Drive Couplings
1. Steel
Steel is commonly used in drive couplings for its high strength, durability, and resistance to wear and tear.
2. Aluminum
Aluminum is a lightweight material used in couplings to reduce overall weight and provide corrosion resistance in certain applications.
3. Cast Iron
Cast iron is used in couplings for its excellent damping properties, thermal stability, and resistance to deformation under load.
4. Polyurethane
Polyurethane is a flexible material used in coupling inserts to absorb shock, dampen vibrations, and compensate for misalignments.
5. Stainless Steel
Stainless steel is used in couplings for its corrosion resistance, high temperature tolerance, and hygienic properties in food and pharmaceutical industries.
