Here are some procedures and best practices that may ease use or help increase
the reliability of your belt tensioning eorts.
LOCK OUT – TAG OUT
›
Take your tension reading as close to the center of the selected
span as is practical.
›
Use the longest belt span that can be readily accessed. Minimum
useable span length is equal to 20 times the belt tooth pitch
for synchronous belts and 30 times the belt top width for “V”
coniguration belts. Using too short a span yields indicated
tensions that may be much higher than actual belt tension due
to the eects of belt stiness.
›
When possible, orient the sensor head with the long edge of the
sensor parallel to the centerline of the belt. This tends to eliminate
any non-reading condition due to aiming error.
›
On new installations, rotate the system by hand at least one full
revolution of the belt to seat and normalize the components.
›
If the top surface of the belt is not accessible, try to beam the
sensor against the edge of the belt. The inside surface of the
belt is equally acceptable.
›
The meter will not give a measurement for a belt under
extremely low tension. Simply increase the drive tensioning
until the meter responds. The meter will beep to indicate
that a reading has been taken.
6.0 Operating Tips
›
It is a good practice to take three successive readings. This will
show the consistency of your methods. If the readings vary by
more than 10%, reassess your measurement technique.
›
Taking multiple readings at dierent belt orientations may help
you identify problems with other drive components. Tension
excursions are indicative of component problems such as a
bent shaft, a poorly mounted sprocket or pulley, or an irregular
pulley groove.
›
The TensionRite® Belt Frequency Meter will measure vibration
frequency (Hz) of all style belts, even belt brands other than
Continental ContiTech. Tension values will also be computed
provided you input the appropriate span and mass constants.
›
When tensioning an array of multiple V-belts, use a single belt
toward the center of the array. Banded belts (Torque Team,™
etc.) are to be treated as a single unit with the mass constant
calculated as a multiple of the single belt value (see “Belt
Mass Constants”).
