Motion control systems
exist primarily to move a load from one place to another, with the motor
playing a crucial role as it converts electrical input into mechanical energy. However,
the motor’s output shaft must be connected to the load in order to move it,
which is why roller chains are also vital for many industrial applications.
chain supplier like Yorkshire-based YB Components supplies multiple options such
as leaf chains and drive chains. Often, moving a load simply requires the motor
to be directly coupled to it, but when this isn’t possible then a popular
option is to employ a roller chain.
What is a Roller Chain?
Roller chains are
a simple method to transmit mechanical energy. They are designed like a normal
chain link structure with multiple cylindrical rollers joined together by
links. The chain is moved by a rotating sprocket connected to the motor, with
the other end of the chain connected to the load.
Such chains are
prone to a lot of wear and tear and need regular lubrication and eventually
replacing, so drive chains suppliers are kept quite busy distributing these
products regularly. Replacing roller chains when they become
worn is important as their pitch increases and they become looser, creating
instability in the motion control system.
right roller chains for your industrial application involves several important
steps to ensure you identify the right product.
How to Select a Roller Chain
One way to
select a roller chain is via the total rated power of the
application (usually measured in kW). You can also choose a roller chain
according to the maximum allowable load it will need to bear.
In either case,
the first thing to be determined is the application’s orientation. Identify
whether the orientation is an ordinary horizontal linear transmission, or whether
it will be vertical, thus requiring a lifting action.
You will also
need to know how much power needs to be transmitted from the motor to the chain
in order to move the load. These calculations will help you determine the
required diameter and speed of the driving and the driven shafts. The centre
distance of the driving sprocket to the centre
of the driven sprocket should also be part of your calculations for a truly
accurate roller chain selection.
Once you have
the information above you can select the chain size as well as the number of
teeth needed for the small and large sprockets, the latter determined by the
speed ratio. Roller chains manufacturers should provide a guide to help you
The last item to
consider is the chain length, which should be easy to identify from the
manufacturer’s guide once you have all the other information described above.
