Taler-bored flange couplings are also known as what type of couplings?

Fixed couplings
Slip couplings
Plastic couplings
Flexible couplings

The correct answer is: Plastic couplings

Taler-bored flange couplings are often referred to as flexible couplings. This designation arises from their ability to allow for some degree of misalignment between the connected shafts, which is essential in dynamic applications. Unlike rigid couplings, which must be precisely aligned and do not accommodate any misalignment, flexible couplings can absorb vibrations and tolerances that occur during operation. The flexibility in these couplings provides various advantages, such as reduced wear on the components, decreased transmission of shock loads, and the capability to accommodate thermal expansion and contractions. This makes them particularly useful in applications where there might be slight movements or changes in alignment due to temperature variations, load changes, or assembly variations. Understanding the functional mechanics of flexible couplings, including Taler-bored flange couplings, is crucial for millwrights and technicians, as it affects operational efficiency and the longevity of machinery.
