These slim units have no finger-traps, the only moving
part being a carriage plate no wider than the outer
section, and the drive belt which covers the slot,
effectively sealing it against dirt or dust ingress.
The bearing design consists of double-ball-bearing
rollers running on 10mm or 14mm shafts respectively,
allowing speeds of up to 10m/s. The specially
constructed AT timing-belt produces an accuracy of
+/-0.1mm, and has a fabric covering which, in
combination with a stainless-steel backing strip on the
return run, reduces noise and frictional losses.
Integration of limit switches is extremely simple:
the moving carriage assembly has a contact plate which
passes over inductive proximity switches. These switches
are another specially designed product which fit into
the grooves of the profile and their position can
therefore be adjusted before finally clamping in
position. Any cables can be hidden in the groove behind
a cover profile and up to four switches can be
incorporated into each slide.
Routine maintenance is very easy. Lubrication is
effected by accessing the internal felt wipers from the
side of the unit. Though normally not required after the
initial setting, belt tensioning is achieved by
adjusting a calibrated tensioning axle and the eccentric
rollers are also easily accessible.
For mounting motors, bolt-on drive sets are available
which incorporate couplings and motor-mounting plates.
Also available are synchronising sets for use when
running a parallel pair of slides together, the linking
shaft being contained within a very neat cover where
desired.
All parts required to build the KLE units are stocked
in our factory in Ripley, Derbyshire. Bespoke units can
therefore be built to tight lead times if necessary. |
