How to store the gearbox reducer?

0-12 months storage

The gearboxes have been treated as follows before delivery:

The shaft ends and other machined surfaces outside the gearboxes are treated with anticorrosive agent. Remove the anti-corrosive agent with solvent before start-up. The internal parts of the gearbox are protected by oil that spreads to their surfaces during the test run. Gear oil is used in the test run.

Anti-corrosive agent is also sprayed inside the gearbox. The gearbox is made airtight by replacing the breather plug with a pipe plug. The effect of the agent is based on slow evaporation and accumulation on the metal surfaces. An invisible layer is formed on the metal surfaces and prevents corrosion by passivating the metal. Replace the pipe plug with the breather before start-up.

In gearboxes with a labyrinth sealing, the gas can escape, in which case the gearbox is enclosed in airtight plastic that prevents the agent from escaping.

This provides protection for storage for up to 12 months in dry indoor spaces with an even temperature. Store the gearbox on a vibration free base.

Longer than 12 months storage

The long-term protection is to be agreed separately when ordering. The long-term storage provides protection to the gearbox in dry indoor spaces with an even temperature. Store the gearbox on a vibration free base. The shaft ends and other machined surfaces outside the gearboxes are treated with anticorrosive agent. Remove the anti-corrosive agent with solvent before start-up.

Rust proofing with anti-corrosive agent

Repeat internal rust proofing of the gearbox every 12 months using anti-corrosive agent. You need not remove the anti-corrosive agent during start-up. During storage, use the gearbox every 12 months manually so that all the shafts rotate at least half a turn. Replace the pipe plug with the breather before start-up.

Rust proofing with oil fill

Alternatively, you can fill the gearbox with oil. When filling the gearbox with oil, use the quantity indicated in the type plate. At the same time, replace the breather with a pipe plug. In addition to rust proofing, the oil protects the bearings from pitting during transportation. During storage, use the gearbox every 2 months manually so that all the shafts rotate at least half a turn. This spreads the oil onto the gear surfaces. Replace the pipe plug with the breather before start-up.

Rust proofing with full oil fill

In case it is not possible to operate the gearbox or rotate the shafts during storage, fill the gearbox completely with oil. Change the oil during start-up. Replace the pipe plug with the breather before start-up.
