How to evaluate the working environment when determining the reasonable maintenance cycle for RF87-35-5.5KW gearbox

Evaluating the working environment of RF87-35-5.5KW gearbox can be approached from the following aspects:

Temperature factor:

Environmental temperature: The working environment temperature of this reducer is generally required to be between -40 ℃ and 45 ℃. If the ambient temperature is below 0 ℃, the lubricating oil should be preheated to above 0 ℃ before starting; The temperature of the lubricating oil during operation should not exceed 90 ℃. When the ambient temperature remains at high temperatures (such as over 40 ℃) or extreme low temperatures for a long time, it will affect the performance of lubricating oil and the thermal stability of components. It is necessary to shorten the maintenance cycle, strengthen the monitoring of lubricating oil and equipment temperature, and check the oil quality and evaluate the equipment condition every 2 to 3 months.

Heat dissipation conditions: If the reducer is installed in poorly ventilated, narrow enclosed spaces, or with other heating devices around it, it will affect its heat dissipation effect, increase the body temperature, accelerate the aging of lubricating oil and component wear. It is necessary to improve the heat dissipation conditions, such as adding ventilation equipment, shortening the maintenance cycle appropriately, and strengthening the inspection of equipment temperature and oil quality.

Dust and impurities:

Dust concentration: If the gearbox is in a high dust environment, such as mines, construction sites, etc., a large amount of smoke and dust may enter the equipment and accumulate in key parts such as transmission gears, exacerbating gear wear, blocking lubrication systems, and reducing equipment performance and lifespan. In this environment, it is necessary to clean the dust on the gearbox housing more frequently, check the sealing of the seals to prevent dust from entering. It may be necessary to conduct a monthly appearance cleaning and sealing inspection, and a comprehensive maintenance every 3 to 6 months, including oil change and inspection of internal wear.

Impurity properties: If impurities in the environment are corrosive or abrasive, they pose a greater threat to the gearbox, corroding metal parts or accelerating wear. Therefore, stricter protective measures should be taken, such as using protective coatings and significantly reducing maintenance cycles. It is necessary to strengthen the inspection and cleaning of the equipment's interior, and a detailed inspection and necessary cleaning and maintenance may be required every 1 to 2 months.

Humidity and moisture:

Air humidity: High humidity environments can easily cause condensation on the surface of the gearbox, leading to rusting of metal parts and potentially emulsifying lubricating oil, reducing lubrication effectiveness. If the working environment is humid, it is necessary to regularly check whether the oil quality contains water or has deteriorated, shorten the oil change cycle to 2 to 3 months, and strengthen the anti rust treatment and drying measures on the equipment surface, such as using desiccants or regularly wiping and drying the surface.

Moisture contact: If the gearbox may come into direct contact with water, such as in a damp basement or outdoor rainy environment, in addition to the above measures, it is also necessary to check the waterproof performance of the seals to ensure that the equipment is not invaded by water. Once the seals are found to be damaged, they should be replaced immediately, and the equipment should be checked for water ingress every time after rain or regularly (such as weekly).
