What is the Nil-Union elastic coupling models O and L?
The Nil-Union elastic coupling models O and L is a mechanical device designed to connect two shafts allowing a degree of flexibility.
These couplings are used to transmit torque between components, such as an engine and a host machine, while absorbing vibrations and compensating for misalignments between the connected shafts.
Misalignment: The second most frequent source of vibration
Misalignment between shafts is the second most common cause of vibration, second only to unbalance. In this scenario, the L model, with its longer crown wheel, presents itself as the ideal choice for dealing with alignment problems between a host machine and an electric motor.
Characteristics of model L:
The main distinguishing feature of the L-model is its extended crown, specifically designed to address alignment challenges. This feature makes it a versatile and efficient solution, especially when misalignment presents itself as an obstacle in operation.
Ease of maintenance
An additional advantage is the ease of disassembly by means of a puller. This feature simplifies maintenance work and allows quick access for adjustments or replacements when necessary.
Nil-Union Flexible Couplings models O and L are not only effective in the connection between receiving machines and electric motors, but also find applications in clutches, brakes and any system that requires the assembly of two aligned shafts.
Types of Misalignment
Misalignment can manifest itself in three different ways, and it is crucial to understand them in order to effectively address the problems.
- Parallel or radial misalignment: Occurs when the centre lines of the axes are parallel but separated.
- Angular or axial misalignment: Occurs due to the angle formed between the centre lines in a plane in space.
- Combined misalignment: The most common situation, where parallel and angular deviations are experienced in the same set of centre lines.
