What is the working principle of the R97R57DT80N4-1:632-0.75KW reducer oil cooling or water cooling system

The working principle of the R97R57DT80N4-1:632-0.75KW reducer oil cooling or water cooling system is mainly to reduce the temperature of the reducer through the circulation of lubricating oil and heat exchange with the cooling medium (air or water), as follows:

Working principle of oil cooling system: There is an oil tank inside the reducer, and the oil pump is located in the oil tank. The oil pump extracts hot oil from the oil pool and delivers it to various parts of the gearbox that require lubrication and heat dissipation, such as gears, bearings, etc. The lubricating oil absorbs the heat generated by the operation of these components during the flow process. The hot oil will then flow through an external or internal heat sink, which is usually made of metal and has a large surface area, effectively dissipating heat to the external environment. After cooling in the radiator, the oil is pumped back by the oil pump and continues to circulate inside the gearbox, forming a closed circulation system to achieve cooling of the gearbox.

Working principle of water cooling system: A common way is to use a pump to circulate the oil in the oil tank to the oil-water heat exchanger, where it is cooled by flowing water. The water and oil transfer heat through the heat exchanger, thereby reducing the temperature of the oil. Another way is to install cooling pipes in the gearbox oil tank. When the oil circulates in the oil tank of the helical gear reducer, the cooling pipes transfer the heat of the oil to the water flowing inside the pipes, which then takes away the heat and lowers the temperature of the reducer.
