Pre-tension highly influences the operating condition and life of the whole
gearing. It is therefore one of the few variables which the user of tooth-belt drives
has to set for himself. Pre-tension depends on the geometry and the stress of the
tooth-belt drive. The desirable transmitting behaviour, precise positioning and repetition precision can only be realised at a specific pre-tension.
The fully electronic measuring instrument enables easy and secure setting of the pre-tension in tooth-belt drives. Special sensors register the vibration of a tooth-belt that has been set in motion.
The instrument registers the belt’s operating frequency. The light-insensitive sensors
allow for a relatively high measuring distance between the sensor and the belt.
For this reason the instrument is very well adjusted to production and installation/assembly conditions. Using the basic physical principle of a string vibration, the
pre-tension and operating frequency of the belt are related to one another.
It is therefore a quick and easy task to calculate the belt’s pre-tension according to
the measured frequency.
