Coupling

Overview:

A coupling is a mechanical device used to connect two shafts together to transmit power and motion from one shaft to another. Couplings are commonly used in various industrial applications where precise alignment and torque transmission are essential. They serve to join shafts that are not directly connected, enabling efficient power transfer while accommodating slight misalignments and vibrations between the connected components.

Features and benefits:

• Torque transmission 
• Misalignment compensation
• Damping and vibration absorption 
• Backlash reduction

Product type and designs:

• Flexible Couplings- These couplings allow for some degree of misalignment between the shafts and can absorb shocks and vibrations. Examples include elastomeric couplings, jaw couplings, and beam couplings.
• Rigid Couplings- Rigid couplings provide a solid connection between the shafts without any flexibility or misalignment compensation. They are often used when precise alignment is required, such as in shaft-to-shaft connections in high-precision machinery.
• Fluid Couplings- Fluid couplings use hydraulic fluid to transmit torque and provide smooth torque transmission, dampening shock loads and protecting connected components.
• Magnetic Couplings- Magnetic couplings transfer torque through magnetic fields, allowing for non-contact power transmission, often used in applications where isolation or hermetic sealing is necessary.

Applications:

Here are examples of applications in which couplings might be used:

• Automotive 
• Aerospace
