How to start up gearbox?

All gearboxes are test-run prior to delivery from the factory. However, the test run does not correspond to actual load conditions: for this reason, you should at first operate the gearbox at a partial load. During the running-in, monitor the operating sound, running smoothness, temperature, lubrication and oil tightness of the gearbox. If you notice something abnormal during running-in, detect and eliminate the cause of the problem before the final start-up.

During operation, pay attention to the operating sound, warm-up, vibration and oil circulation. Overheating, for example, is often caused by an excessive amount of oil in the gearbox. For gearbox operation, the recommended maximum temperature is +90 °C. In higher temperatures, use special lubricants and/or additional cooling. The oil change interval is shorter in high temperatures.

Stray current shall be prevented from entering the bearings and toothings of the gear unit. In case there is a possibility of stray currents, it is recommended to make necessary stray current measurements during commissioning, in order for the supplier of the whole equipment to be able to take the necessary actions to prevent stray currents.
