Description

technical field [0001] The invention relates to the technical field of lubricating oil detection, in particular to a lubricating oil detection device for a reducer and a use method thereof. Background technique [0002] Lubricating oil is a liquid lubricant used on various types of machinery to protect machinery and processed parts. It is widely used in transmission equipment such as engines, compressors, and reducers of ships and vehicles. It is important for the loss and life of transmission machinery. Impact, can effectively prevent component wear and corrosion candle. [0003] For the reducer, most of the failures are related to the lubricating oil. The deterioration of the lubricating oil directly reduces the lubrication effect, aggravates the wear and temperature rise between the transmission parts, accelerates the failure of gears, bearings and other components, and causes a series of deceleration. Gear failure will greatly shorten the normal service life of the redu...

AI Technical Summary

Problems solved by technology

[0003] For the reducer, most of the failures are related to the lubricating oil. The deterioration of the lubricating oil directly reduces the lubrication effect, aggravates the wear and temperature rise between the transmission parts, accelerates the failure of gears, bearings and other components, and causes a series of deceleration. Gear failure, greatly shorten the normal service life of the reducer

[0004] After the lubricating oil is used for a period of time, due to the oxidation, condensation, hydrolysis, etc. of the lubricating oil itself, or the intrusion of external impurities, particles, moisture, etc., the lubricating oil will deteriorate and reduce its lubricating performance, especially water and iron filings Such impurities can cause a sharp decline in the deterioration of lubricating oil, resulting in a sharp decline in the basic performance of its lubrication

After the lubricating oil deteriorates, it cannot effectively lubricate the surface of the parts, and because the lubricating oil brings impurities such as iron filings, the wear on the surface of the transmission parts is accelerated, so the lubricating oil needs to be replaced frequently to ensure the normal operation of the reducer

[0005] Because the quality of lubricating oil requires extremely experienced operators to judge only by visual observation, it is difficult for ordinary operators to judge, and even experienced operators sometimes make mistakes in judgment, resulting in premature or too late lubricating oil. late replacement

In addition, since the reducer is a closed type of lubrication, the lubricating oil needs to be extracted after the reducer stops working and is disassembled. Therefore, the replacement of the lubricating oil of the general reducer does not judge whether the lubricating oil needs to be replaced in advance, but according to past experience, When the reducer works for a fixed period of time, the lubricating oil is replaced, that is, the current reducer lubricating oil replacement cycle is fixed

However, the replacement cycle will be different under different operating conditions. Replacing the lubricating oil too early will waste the lubricating oil and increase the maintenance cost of the reducer. Replacing the lubricating oil too late will affect the lubrication effect of the reducer, which will affect the working performance and use of the reducer. life

[0006] To sum up, at present, the lubricating oil of the reducer is only replaced based on experience and at a fixed period, so the lubricating oil is replaced either too early or too late, and it is difficult to reduce the lubrication and maintenance cost of the reducer while ensuring the lubricating performance of the lubricating oil
