[0002] The reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering.

[0004] Anything that is applied between two objects in relative motion and can reduce the friction and wear caused by contact between the two objects is considered a lubricating oil.

[0005] When the reducer is in use, lubricating oil needs to be added so that the gear set inside the reducer can be lubricated and the gear sets can be meshed and rotated. The quality of the lubricating oil in the reducer will be affected after long-term use. The quality of the lubricating oil needs to be tested for timely replacement.

If they are directly inserted into the reducer, they are likely to collide with the gears, causing damage to the gear set or the sensor. The connection is also prone to lubricating oil leakage and inaccurate data processing. Utility Model Content
