Automatic circulating cooling system for lubricating oil of speed reducer

The invention relates to the technical field of speed reducers, and discloses a speed reducer lubricating oil automatic circulation cooling system which comprises a central controller, a filtering mechanism, a cooling mechanism, a detecting mechanism and a supplementing mechanism, and the central controller is used for driving other mechanisms according to feedback of the detecting mechanism; the filtering mechanism is used for filtering the lubricating oil; the cooling mechanism is used for cooling lubricating oil in working, and the detection mechanism is used for detecting the working state of the lubricating oil; and the supplementing mechanism is used for supplementing lubricating oil in the speed reducer. Through mutual cooperation of the primary cooling module and the secondary cooling module, after the detection mechanism completes temperature detection of lubricating oil, switching between the primary cooling module and the secondary cooling module is carried out through the auxiliary cooling module,
