What is a coupling gearbox?

A gear coupling is a mechanical device intended to transmit torque between two shafts that are not collinear. The coupling commonly comprises two flexible joints, one fixed to each shaft. These joints are frequently associated by a third shaft called the spindle.

What is marine coupling?

Marine couplings are capable of accommodating 10mm of expansion/contraction per fitting, flange adaptors 5mm which reduces the need for supplementary expansion joints or bellows.

What are the three types of coupling?

Following are the different types of coupling:

• Rigid Coupling.
• Sleeve or muff coupling.
• Clamp or split-muff or compression coupling, and.
• Flange coupling.
• Flexible coupling.
• Bushed pin-type coupling,
• Universal coupling, and.
• Oldham coupling.

What are the two types of coupling?

Types of Couplings

• Rigid coupling.
• Flexible coupling.
• Sleeve or muff coupling.
• Split muff coupling.
• Flange coupling.
• Gear coupling.
• Universal joint (Hooke’s joint)
• Oldham coupling.

What is the advantage of gear coupling?

Gear couplings offer several advantages over other couplings, including moderate misalignment capacity, exceptional torsional stiffness and very high torque density.

What is marine type flange coupling?

In Marine Flange Coupling, flanges are formed integrally with the shafts. Depending on the perimeter of the shafts, the number of bolts used is decided. It ranges from four to twelve bolts. These types of flange coupling elongated bolts without a head are been used to hold the shafts together.

What will happen if the coupling fails?

However, if just one of these factors is not met, a coupling can prematurely fail, causing anything from a small inconvenience, to a significant financial loss, and even the potential of personal injury.
