QTL TAPER BUSHINGS
INSTALLATION INSTRUCTIONS
QTL "Quick Detachable" (QD) bushings are
commonly used throughout industry for
convenience and design flexibility. QTL bushings
are easy to install and remove. They are made of
quality gray or ductile iron and are easily installed
by tightening capscrews.
The bushing is inserted into a mating component
that compresses the bore of the bushing. The shaft
is gripped in such a way that no external keys are
required. QTL bushings are easily removed by
using the cap screws as well.
QTL bushings have two sets of holes so that they
may be mounted in a conventional or reverse
position. This allows cap screws to be installed
through the hub or bushing flange, whichever is
more convenient. No matter which way the
component is installed, cap screws are always
inserted from the outside where they can be
easily assembled.
QTL bushings are available in stock for all popular
bores.
Some power transmission products that may use
QTL bushings are pulleys, sprockets, sheaves,
couplings, fans, impellers, and other products that
need to be shaft mounted.
TYPICAL INSTALLATION OF QTL BUSHING ON MOTOR SHAFT
Make sure the small end of taper bushing is toward the motor
as shown in diagram above.
To assemble, place cap screws into bushing flange through
drilled holes.
Finger tighten the screws into the hub. Slip the assembled
unit into desired position on shaft, small taper end first.
Tighten all cap screws to specified wrench torque see page
12.
To remove, simply reverse cap screws. As they loosen, the
grip between bushing and hub will be released.
Ensure that the bushing flange is toward the motor as shown in
diagram above.
To assemble, place QTL bushing in the hub and insert cap
screws into the hub through drilled holes.
Finger tighten capscrews into holes in bushing flange. Slip
assemble unit into desired position on shaft, flange end first.
Tighten all capscrews to specified wrench torque see page 12.
To remove, reverse capscrews. As they loosen, the grip between
bushing and hub will be released.
