What is the principle of no-load operation method inside the dry DCY gear reducer?

The core of no-load operation drying is to use the friction of the transmission parts and the oil churning loss to generate heat, so that the temperature in the box rises evenly to 40-60°C, forming a slight positive pressure and humidity gradient, vaporizing the water from the oil/metal surface and expelling it through the respirator, achieving safe, uniform and controllable drying.
- Heat generation
- Gears and bearings at all levels generate heat simultaneously, and the heat flow circulates through the shell and oil to form a uniform temperature field, eliminating 'cold zones' and ensuring that moisture in all parts is vaporized simultaneously.
- mass transfer drive
Water forms a suspension or emulsion in the oil. The temperature rise accelerates the separation of oil and water, which facilitates subsequent sedimentation or filtration removal and restores the oil's lubrication performance.
- Under no load, frictional heat is generated by gear meshing, bearing rolling/sliding and oil agitation. The power loss is about 2%-5% of the rated power, causing the oil temperature and shell temperature to rise slowly to avoid local overheating.
- Temperature field homogenization
- The rise in temperature inside the box causes the moisture vapor pressure to be higher than the environment, forming a humidity gradient; the respirator maintains a slight positive pressure, continuously discharges wet steam, and promotes moisture migration from the interior to the surface and evaporation.
The working process of DCY reducer reflects a high degree of accuracy and stability. From the beginning of the motor drive to the final driving force output, every link has been carefully designed and rigorously tested to ensure the efficient operation of the entire system. The meshing of its internal gears is tight and accurate, reducing energy loss and improving transmission efficiency.
In addition, DCY reducer also has many advantages such as compact structure, light weight and low noise. These characteristics enable it to perform excellently in many industrial applications, such as metallurgy, mining, lifting, transportation, chemical industry and other fields. Its compact structural design saves space, reduces equipment weight, and reduces transportation and installation costs; while its low noise characteristics improve the working environment and increase operator comfort.
