Simple structure
A roller chain coupling consists
of one duplex roller chain and
two sprockets for a simplex
chain. Handling is very simple
as both the shafts (driving
shaft and driven shaft) can be
connected and disconnected
by inserting or removing
connecting pins (cotter type).
Easy alignment
Owing to the play between the respective components
of the chain and the play between the roller chain and
the sprockets, the eccentricity and angle error can be
generally allowed as follows:
Small but powerful
Since a powerful roller chain is engaged with the
sprockets at all the teeth, a large torque can be
transmitted, though the coupling itself is smaller than
other kinds of couplings.
