What Is a Fixed Flange Shaft Coupling?
A fixed flange shaft coupling is a mechanical component that connects two rotating shafts by keying and bolting a flange to the end of each shaft.
Shaft couplings are critical in mechanical systems for connecting two rotating shafts and transmitting power. They are categorized into permanent couplings, which remain connected during operation, and clutches, which allow for disconnection.
The fixed flange shaft coupling aligns the drive and driven shafts perfectly straight, making it highly reliable and suitable for transmitting significant torque. Despite its robust structure and precision, it requires exact shaft alignment.
Uses of Fixed Flange Shaft Couplings
Fixed flange shaft couplings primarily serve three functions:
- Power Transmission: They transmit power from the drive side to the driven side.
- Error Absorption: They absorb alignment errors between the drive and driven sides.
- Vibration Absorption: They reduce vibration from the drive side to mitigate the impact on the surrounding environment.
These couplings focus on power transmission. Precise alignment is crucial to minimize vibration and shock effects during rotation.
Principle of Fixed Flange Shaft Couplings
1. Classification of Shaft Couplings
Fixed flange shaft couplings fall into four categories:
- Fixed shaft couplings (linear alignment)
- Deflection shaft couplings (uniaxial flexibility)
- Flexible shaft couplings (crossed shaft flexibility)
- Other types (parallel shaft flexibility)
They connect driving and driven shafts in a straight line using a flange and bolts, ensuring the rotation is transmitted accurately and the shaft centers are perfectly aligned.
Another type is the flange-type deflection shaft coupling, which allows for some misalignment between the shafts due to its flexibility.
2. Features of Fixed Shaft Joints
Deflection shaft couplings are characterized by:
| Type | Characteristics |
| Cylindrical |
|
| Flange type |

Structure of Fixed Flange Shaft Couplings
These couplings consist of two flanges connected by bolts, with precision-machined bolt holes to minimize clearance. They cannot tolerate angular misalignment, emphasizing precise alignment for optimal performance.
They excel in systems requiring high precision, minimizing misalignment and displacement during torque transmission.
Other Information on Fixed Flange Shaft Couplings
1. Material
Various materials are specified for different components such as flanges, bolts and nuts, and spring washers.
2. Maintenance
Regular inspections and maintenance are essential to address potential issues like nut loosening or wear. Adjustments may be necessary to manage increased vibration or noise.
