Inspection and repair on ZAMBELLO gearbox

This client from Belgium came to us with this ZAMBELLO . We inspected the gearbox and performed a repair. After a succesful testrun we shipped the gearbox back to the client.

This report presents the work that was carried out on tyre retreading machines 1, 2 and 3. GBS was invited to perform the first of a series of periodic inspections on their machines.

The visit consisted of:

- TRM 1: Vibration measurement, visual inspection and oil analysis,
- TRM 2: Vibration measurement and oil analysis,
- TRM 3: Vibration measurement

The three inspected gearboxes are in new machine condition according to the vibration measurements. For TRM 1 the visual inspection also showed a good condition of the gears and bearings. The results of the oil analysis will be presented in a separate report in about two weeks.

To ensure the best results during a future vibration measurement it is recommended to run the machines in actual production conditions.

This means that the gearboxes are:

- Producing continuously so that the measuring time is not limited
- Operating at high speed and full load
- At working temperature

Further recommendations are:

-To continue vibration measurements and oil analysis according to the planned intervals
-To perform a visual inspection once per year
- If a significant change in oil composition, or a change in vibration levels or fault frequencies is detected, perform a visual inspection.
