A reducer is required when using a cooling tower. Its main function is to reduce noise as much as possible while ensuring the normal operation of the cooling tower. The inverted design of the reducer can prevent the tower body from being squeezed and dynamically loaded by the fan and reducer, thereby extending the life of the cooling tower body.

[0003] A Chinese patent discloses a cooling tower reducer device with the authorization announcement number CN204268954U. This patented technology not only improves the stability of equipment operation, reduces the wear and damage to the tooth surface caused by fatigue cracks on the metal surface of the tooth surface and the flaking of the surface metal, but also reduces the workload of daily equipment inspection and maintenance and spare parts costs.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing cooling tower reducer needs to be regularly filled with lubricating oil when in use to prevent excessive friction between the gears and bearings inside the reducer, thereby generating noise and heat. However, when lubricating oil needs to be added in the prior art, the threaded rod used for fixing is mostly unscrewed, the lubricating oil storage box is disassembled, and the lubricating oil is added inside. The overall process is relatively cumbersome, which increases the downtime of the equipment and reduces the use effect. Utility Model Content
