Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to an oil-immersed coupling. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. They rotate together during the transmission of motion and power and do not disengage under normal circumstances. Oil-immersed coupling is a type of coupling.

[0003] The oil-immersed coupling uses lubricating oil for lubrication and cooling, which can reduce the thermal runaway phenomenon of the transmission and extend the life of the bearing. This type of coupling is suitable for industrial transmission systems that require long-term operation, wear resistance, and corrosion resistance.

[0004] For oil-immersed couplings, lubricating oil is used for lubrication and cooling. Due to the high viscosity of lubricating oil, the coupling after adding lubricating oil will be sticky with a lot of dust when working in a complex industrial environment. Too much dust will affect the use of the coupling.

[0005] In view of this, we propose an oil-immersed coupling. Utility Model Content
