Couplings are mechanical components used to connect two in-line shafts to enable one shaft to drive another at the same speed. A coupling can be rigid or flexible, allowing various amount of angular, radial, and axial misalignment between the two shafts.
Coupling fall into two main categories: Material Flexing and Mechanical Flexing. The material flexible types obtain their flexibility from stretching or compressing a resilient material, such as rubber, or from the flexing of thin metallic discs or grid. ... All metal mechanical flexing couplings require lubrication.
What are the two types of coupling?
Coupling fall into two main categories: Material Flexing and Mechanical Flexing. The material flexible types obtain their flexibility from stretching or compressing a resilient material, such as rubber, or from the flexing of thin metallic discs or grid.
The levels of coupling below are ordered from high to low: Content Coupling: Content coupling, or pathological coupling, occurs when one module modifies or relies on the internal workings of another module. ... Common Coupling: Global coupling, or common coupling, occurs when two or more functions share global data.Jul 25, 2016
What is the advantage of coupling?
To compensate for misalignment of connected shafts. To introduce mechanical flexibility ( such as in case of flexible coupling ). To reduce and absorb transmission of shock loads from one shaft to another shaft. To provide protection against overloads.Sep 28, 2020
