Disc Coupling for Pumps and Compressors


Disc coupling is a type of flexible coupling commonly used in pumps and compressors. It provides a reliable and efficient connection between the driving and driven equipment. This article will explore the features and benefits of disc couplings, as well as how to select or customize the right coupling for specific applications.

1. Understanding Disc Coupling

Disc coupling is composed of a series of thin metal discs with slots that interlock to form a flexible and torsionally stiff connection. This design allows for angular, parallel, and axial misalignment while transmitting torque and compensating for shaft misalignment.

2. Advantages of Disc Coupling

– High torque transmission capacity: Disc couplings can transmit high torque loads, making them suitable for heavy-duty applications.
– Torsional stiffness: The interlocking design of the discs provides excellent torsional stiffness, ensuring accurate torque transmission.
– Compact size: Disc couplings have a compact and lightweight design, allowing for easy installation and reduced space requirements.
– Maintenance-free operation: Due to their simple construction, disc couplings require minimal maintenance and have a long service life.
– Dampening vibration: The flexible nature of disc couplings helps dampen vibrations, reducing stress on the connected equipment.

3. Selecting and Customizing Disc Coupling

When selecting or customizing a disc coupling, several parameters and practical conditions need to be considered:
– Torque capacity: Determine the required torque capacity based on the operating conditions and power transmission requirements.
– Misalignment tolerance: Evaluate the expected angular, parallel, and axial misalignment to select a disc coupling with appropriate misalignment capabilities.
– Operating speed: Consider the rotational speed and dynamic balancing requirements to ensure smooth and efficient operation.
– Environmental factors: Evaluate the temperature, humidity, and presence of any corrosive or hazardous substances to choose the right material for the disc coupling.
– Space limitations: Determine the available space for the coupling installation to select a compact design that fits within the given constraints.

4. Does Disc Coupling Need Lubrication?

Disc couplings are typically designed for dry operation and do not require lubrication. The absence of lubrication simplifies maintenance and reduces the risk of contamination in sensitive applications.
