Why Does The Reducer Use Oil?
With the rise of tribology in the 1860s, an organic connection was established between friction, wear, lubrication, and part design.
1. Wear
Initial wear stage –
Due to manufacturing and installation reasons, the initial wear of the parts is relatively fast, so the first oil change time is short
Stable wear stage –
The wear rate is slow and constant, usually the length of the mechanical life refers to this period of time
Accelerated wear stage –
Decrease in mechanical efficiency, change in gap and shape, generate noise and vibration, and must be repaired or replaced
2. Lubrication
The lubrication mechanism of gear transmission is to allow lubricant to enter the meshing gear surface, forming a lubricating film to force the meshing tooth surfaces to separate, and turning the dry friction of the meshing tooth surface into internal friction between the internal molecules of the lubricant.
Reduce friction
Avoid direct contact between metal and metal, turning dry friction into fluid friction, or due to the formation of physical or chemical adsorption film or reaction film on the tooth surface to reduce friction and avoid rabbit pitting and adhesion;
Reduce wear
The lubricating film formed between the tooth surfaces can reduce friction and support load, reduce tooth surface loss and scratches, and maintain normal tooth surface meshing;
Heat dissipation
The lubricating oil can take away the heat generated between the meshing tooth surfaces and avoid the occurrence of tooth surface damage such as gluing caused by excessive temperature;
The lubricating oil covers the surface of the gears and bearings to isolate air, water vapor and anti-corrosion gases, avoiding transmission.
Anti-rust
Oxidation and corrosion of moving parts;
Reduce vibration and noise
Due to the viscosity of lubricating oil, it can reduce gear vibration, shock and noise;
Remove dirt
The lubricating oil can wash away the abrasive particles and impurities on the tooth surface, take away the dirt in the oil pool or lubrication system, ensure the cleanliness of the tooth surface and reduce wear.
