Pre-tension
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.

The advantages at a glance
  • Easy-handling.
  • Contactless measurement with one-sided belt touch.
  • Measurement of all belt types including all different types of tension members, e.g. steel, Kevlar, fibreglass.
  • Reliable measuring results that are highly reproducible.
  • Connection for external sensor for measuring inaccessible parts.
  • An LCD indicating how full the battery is.
  • Visual and acoustic indication of necessity of battery change.
