Couplings are a form of power transmitter used as connecting components between two shafts.
Gear couplings are the couplings used for high power high torque applications. When compared to
universal joints, they can tolerate more torque but produce more vibration. It is made up of two
hubs consisting internal and external teeth along with a one or two piece sleeve. There are several
types of gear couplings available in the market like half rigid half flexible gear coupling 6 cm and
many more. One should choose the one that best suits their work.
There are several different types of gear couplings that are used as per their usage and function in
Full Gear Couplings: These are the double engagement forged steel couplings that are used
in almost all the major industrial applications. They have a large end float capacity so as to
compensate for both angular misalignment and parallel shaft misalignment.
Rigid Couplings: Rigid couplings are used for connecting shafts that are aligned. They are
considered to be the simplest kind of gear couplings. They are used mainly where exact shaft
alignment is needed. Even the slightest of shaft misalignment can affect the performance as
well as the existence of the coupling.
Half Rigid Half flexible gear coupling 6 cm: These couplings consist of a rigid as well as a
flexible half. The open half is regular flexible coupling consisting of an inner hub and an
outer sleeve. The other half consists of a rigid half with a flanged hub.
Floating Shaft Assemblies: These couplings are used for long distance shaft connections.
They offer a good solution for powering electrical equipment with a motor placed at a
distance with no place to install connecting shaft supports.
Slide couplings: These are used in places where axial movement is required with a
consideration towards thermal shaft expansion too.
Shear pin couplings: In addition to other gear couplings, some industries also use shear pin
couplings for applications that get clogged or are often overrun. They help in avoiding
damage to the machine by shutting off as soon as the load gets dangerously high.
Disconnect Couplings: They are also quite similar to the shear pin couplings in terms that
they can also be disconnected as the work demands. They can used for both high speed as
well as medium applications.
Flanged Gear Couplings: These gear couplings comprise of short sleeves that are surrounded
by perpendicular flanges.
Continuous sleeve gear couplings: In these couplings, shaft ends are joined together and also
abutted against one another before they are all enclosed in a sleeve. These sleeves are made
of mostly copper but also of nylon in some cases.
There are several different types of gear couplings available in the market. What is important is that
right coupling should be chosen for the right application. If you start using for example a half rigid
half flexible gear coupling 6 cm for an application that may require a fully rigid coupling, it will affect
the performance of both the machine as well as the coupling. Thus, always make a choice after
taking all the pointers and considerations in mind.
