nnnnSi
nnnnJVL ...whan motors must be controlled
nnnnThese flexible and very robust
nnnncouplings consist of only 3 parts
nnnnand are intended for non-
nnnncontinuous operation. They offer
nnnnzero-play operation, a high
nnnntorsional stiffness and are easy
nnnnto mount in even difficult
nnnninstallations. Typical applica-
nnnntions are in motion control, e.g.
nnnnin positioning systems, transport
nnnnsystems, optical systems, etc.
nnnnA main feature of these cou-
nnnnplings is the ability to absorb
nnnnradial displacement without
nnnnbending. Since there is no
nnnnpersistent force from bending,
nnnnbearing load is low.
nnnnThe torque is transmitted by a
nnnn"floating" moulded disc which
nnnnabsorb deflections. At the same
nnnntime it acts as a mechanical
nnnnsafety fuse. Under serious
nnnnoverload, the disc fails, fractur-
nnnning cleanly, and thus provides
nnnnsome degree of protection to
nnnnpersonnel and machinery. The
nnnndisc is easy to change and the
nnnnentire construction, in which the
nnnnparts can bepulled from one
nnnnanother, enables disassembly
nnnnwithout removing the drive
nnnndiscs from axles.
nnnnThese couplings require that
nnnnboth axles have sufficient
nnnnsupport. They must not be used
nnnnon long unsupported axle
nnnnlengths and must not be used in
nnnnpairs with an intermediate
nnnnunsupported axle.
