Synchronous Belts
Installation Guide
1. Inspect sprockets
The following sections outline installation procedures that
will ensure maximum life and performance for your Continental
ContiTech synchronous belts such as Hawk Pd,® Blackhawk Pd,®
Falcon Pd® and SilentSync® belts.
Worn teeth will cause belt wear and/or damage. Nicks or
gouges can cut the belt. Dirt on the teeth and in the grooves
can abrade the belt and oil can attack belt materials.
Use a stiff brush to remove rust and dirt. Use a soft cloth to
wipe off oil and grease.
Make sure the components are ready for installation. Clean all
shafts, removing any nicks or burrs. Clean all mating surfaces
of the sprocket, bushing and shaft. Do not use lubrication or
anti-seize solution on any of these surfaces.
Make sure the shafts are true and parallel by accurately
measuring the distance between the shafts at three points
along the shaft. The distance between the shafts should be
the same at all three points as shown.
Also, make sure the shafts are rigidly mounted. Shafts should
not deflect when the belt is tensioned.
2. Install hardware
Correct sprocket selection and installation is important. Before
performing any installation, follow correct lockout procedures
to prevent any accidents.
IMPORTANT:
Disconnect power supply to machine
before
doing ANY work
.
QD® Bushing
If the sheaves are made with a QD® hub,
follow these installation and
removal instructions:
3. How to install a sprocket with a QD® hub
For conventional mounting, insert bushing into the sprocket,
aligning the tapped holes in the bushing flange with the thru
holes in the sprocket hub.
Insert capscrews through the thru holes and into the
tapped holes.
Insert the key into the keyseat of the shaft.
With capscrews to the outside, place the sprocket and bushing
assembly on the shaft, positioning the assembly with the
bushing flange towards the shaft bearings. Reverse mounting
the QD® bushing can be advantageous for some applications.
Mount the other sprocket in a similar manner.
