Servo planetary reducer is a kind of high-precision transmission equipment, and its accuracy and service life are affected by a variety of factors. Among them, the lubrication method is one of the important factors. This article will discuss the relationship between the accuracy of the servo planetary reducer and the lubrication method, and how to choose the appropriate lubrication method to maintain high precision and prolong the service life.
First of all, the accuracy and service life of the servo planetary reducer are affected by the lubrication method. Different lubrication methods have different effects on the accuracy and service life of the reducer. Generally speaking, the selection of lubrication method should be selected according to the circumferential speed and rotation speed of the gear.
At low speeds, grease lubrication is generally used. Grease lubrication has the advantages of simplicity and low cost, which can form a thicker oil film, reduce metal contact, and reduce friction and wear. However, the disadvantage of grease lubrication is that it is easily affected by ambient temperature and humidity, resulting in poor lubrication, which affects the accuracy and service life of the reducer.
At medium speed, oil bath lubrication is generally used. Oil bath lubrication effectively lubricates gears and bearings, reducing friction and wear and extending service life. However, the disadvantage of oil bath lubrication is that it is easy to cause oil pollution and waste, and the lubricating oil needs to be checked and replaced regularly. af60-3-s2-p2-19

At high speeds, forced lubrication is generally used. Forced lubrication can effectively improve the lubrication effect and reduce friction and wear, and is suitable for high-speed, high-precision reducers. However, the disadvantage of forced lubrication is that the lubrication system needs to be checked and cleaned regularly, and the maintenance cost is high.
Secondly, the selection of lubricating grease is also one of the important factors affecting the accuracy and service life of the servo planetary reducer. When choosing a grease, the following factors need to be considered:
Viscosity: Viscosity is an important indicator of the fluidity of lubricating grease. If the viscosity is too high, the grease will adhere to the surface of the gear, and it is not easy to form a stable oil film, which will affect the lubrication effectIf the viscosity is too low, it is easy to cause leakage and contamination. Therefore, when selecting lubricating grease, it is necessary to choose the appropriate viscosity according to the actual situation of the reducer.
Extreme pressure: Extreme pressure refers to the frictional properties of grease when subjected to high pressures. Grease with high extreme pressure can form a stable oil film under high pressure, effectively reducing metal contact, reducing friction and wear. Therefore, when choosing a lubricating grease, its extreme pressure performance needs to be considered.

Temperature resistance: Temperature resistance refers to the ability of grease to deteriorate at high temperatures and not easy to solidify at low temperatures. The grease with good temperature resistance can adapt to the working needs under various temperature conditions to ensure the lubrication effect and service life. Therefore, when choosing a lubricating grease, its temperature resistance needs to be considered.
Water resistance: Water resistance refers to the ability of grease to deteriorate when exposed to water or high humidity. The water resistance of grease directly affects the accuracy and service life of the reducer. Therefore, when choosing a lubricating grease, its water resistance needs to be considered.

Finally, in actual operation, the selection of lubrication methods and grease needs to be comprehensively considered in combination with the actual situation. Generally speaking, the servo planetary reducer has taken the lubrication problem into account in the design and production process, and selected the appropriate lubrication method and grease type. However, if the reducer is used in a harsh environment, with a high frequency of use or abnormal conditions, it is necessary to pay special attention to the lubrication problem and take corresponding measures for maintenance and maintenance.
To sum up, there is a close relationship between the accuracy of the servo planetary reducer and the lubrication method. The correct selection of lubrication methods and grease types is of great significance to improve the accuracy and service life of the reducer. In actual operation, it is necessary to consider comprehensively in combination with the actual situation and take corresponding measures for maintenance and maintenance to ensure the normal operation of the reducer and prolong the service life.
