Did you know that changing the kind of lubrication used with a speed reducer or gearbox can actually have a significant influence on the amount of energy consumed by your factory each year? According to the U.S. Energy Information Administration (EIA), about 70 percent of the energy consumed each year in the United States comes from electrical motors inside factories and other facilities across the United States. This is a huge amount of energy use that is a necessary part of the world today, but can also be a strain on the environment and the cost of operating a factory.
So what does this information have to do with speed reducers? According to the data by the EIA, improving the efficiency of all speed reducers used in motors by one percent can save the energy equivalent of one factory’s entire energy use. Changing the type of lubrication used in a speed reducer can actually increase the efficiency of the unit by more than one percent, which means that proper lubrication has a huge impact on the energy use of a factory.
Speed reducer suppliers have a recommended type of lubrication for each speed reducer that they manufacturer, but not every factory continues to follow these guidelines. The main drags that occur on a speed reducer due to improper lubrication are oil churning, friction, and seal drag. Oil churning occurs when the speed reducer gets caught on leftover oil sump. Friction occurs due to the wrong kind of lubrication or not enough lubrication. Without proper lubrication, seals cannot function properly.
All of these factors add up to a reduced efficiency in the speed reducer. If you want to improve the efficiency of your motors and save on energy costs, always follow the recommended lubrication guidelines set into place by speed reducer suppliers and manufacturers.
