Check whether the maximum torque with the motor is not exceeded at full load:
Formula: Torque (Nm) = (power (kW) x eta (%) x 9550) / output speed (min)^-1)
eta (%) = efficiency of the transmission

The efficiency is crucial for the design of an application and is influenced by the gearing data. In the overview of the gearing data you will find values of the dynamic (n)₁=1400) and the static efficiency. It is noted that these table values are valid only after the entry time. In the case of a transmission with dynamic self-locking, the output shaft comes to a standstill immediately when the worm shaft is no longer driven. The theoretical prerequisite for dynamic self-locking is a dynamic efficiency ETA_{dd dd}<0,5. Bei statischer Selbsthemmung ist ein Anlauf aus dem Stillstand bei treibender Abtriebswelle nicht möglich. Statische Selbsthemmung liegt bei einem statischen Wirkungsgrad ETA_s<0,5 vor. In der Übersicht sind die Angaben zur Selbsthemmung nur als Richtwerte wiedergegeben. Die Bedingungen können durch Vibrationen oder Stöße beeinträchtigt werden. Bei der Prüfung der Selbsthemmung von Doppelschneckengetriebe ist zu beachten, dass sich der Gesamtwirkungsgrad aus dem Produkt der beiden einz elnen Wirkungsgrade ergibt, d.h. ETA_g = ETA₁ x ETA₂.

BETRIEB UND EINFAHREN

In order to achieve the best performance, the transmission must be run-in during the first hours of operation by a gradual increase in power; In this phase, a temperature increase is considered normal.
In the event of malfunction, noise, oil leakage, etc. The transmission shall be immediately stopped and the cause removed as far as possible. Alternatively, you can send the part to our factory for control.

WARTUNG

The worm gearboxes from size 25 to size 90 and the precursor modules are lubricated with synthetic permanent oil and therefore do not require any maintenance.
The 110 and 130 size gearboxes are lubricated with mineral oil and are equipped with a vent plug. Therefore, the oil level must be checked regularly and, if necessary, replenished with the same oil or an oil compatible with the one indicated in our catalogue.
For 110 and 130 size gearboxes, the oil must be replaced after the first 300 hours of operation, with the correct quantity according to the installation position, as indicated in our catalogue, after the interior of the gearbox has been thoroughly cleaned.
