随着工业精细化程度的加深,工业制造中齿轮的作用不可忽视,每一次齿轮完美的啮合都离不开齿轮油的作用,虽然齿轮油更换频率较低,一般半年更换一次,但是千万不能因此而忽视它,一旦齿轮油出问题就会引起设备异常情况!为什么齿轮油这么重要?今天小编就给大家分析分析。
With the deepening of industrial refinement, the role of gears in industrial manufacturing cannot be ignored. Every perfect meshing of gears cannot be separated from the role of gear oil. Although the frequency of gear oil replacement is low, and it is generally replaced every half a year, it must not be ignored. Once the gear oil goes wrong, it will cause abnormal equipment conditions! Why is gear oil so important? Today, I will give you an analysis.
齿轮油以石油润滑油基础油或合成润滑油为主,添加抗磨剂等调制而成,用于设备齿轮间的传动装置,主要起润滑、防止磨损的作用,以延长齿轮使用寿命,提高传递效率。
The gear oil is mainly composed of petroleum lubricating oil base oil or synthetic lubricating oil and added with anti-wear agent. It is used for the transmission device between gears of equipment. It is mainly used to lubricate and prevent wear, so as to prolong the service life of gears and improve the transmission efficiency.
1、合适的黏度和良好的粘温性
1. Suitable viscosity and good viscosity temperature property
齿轮油粘度大,可以形成较厚的油膜,增强齿轮的承载能力,但粘度又不能过高,不然可能会因内摩擦过大而使油膜破裂,所以齿轮油的黏度需在合适的范围。齿轮在摩擦产生的高温条件下,需要齿轮油仍能保持足够的润滑油膜,在低温条件下,也能保持足够的流动性,不致发生磨损,而良好的粘温性,就可以保证齿轮油在高温、低温条件下都有足够的润滑油膜,防止磨损。
The gear oil has high viscosity, which can form a thick oil film and enhance the bearing capacity of the gear. However, the viscosity should not be too high, or the oil film may be broken due to excessive internal friction. Therefore, the viscosity of the gear oil should be in a proper range. Under the high-temperature conditions caused by friction, the gear oil is required to maintain sufficient lubricating oil film, and under the low-temperature conditions, it can also maintain sufficient fluidity to avoid wear. The good viscosity and temperature property can ensure that the gear oil has sufficient lubricating oil film under the high-temperature and low-temperature conditions to prevent wear.
2、足够的极压抗磨性
2. Sufficient extreme pressure wear resistance
齿轮负荷一般都在490MPa以上,可高达2942MPa,这就需要齿轮油能在持续的高速、高负荷下,迅速形成油膜并长久保持,达到防磨损、防擦伤的效果。
The gear load is generally above 490mpa, which can be as high as 2942mpa. This requires that the gear oil can quickly form an oil film and maintain it for a long time under the continuous high speed and high load, so as to achieve the effect of anti-wear and anti scratch.
3、良好的氧化安定性和热安定性
3. Good oxidation stability and thermal stability
齿轮油工作时多处于高温环境下,高温会加快油的氧化反应,使其粘度增大,降低油的流动性,还会产生不溶物及腐蚀性物质,加速油的变质,影响齿轮油的性能,甚至造成金属的腐蚀和锈蚀。
When gear oil works, it is mostly in high temperature environment. High temperature will accelerate the oxidation reaction of oil, increase its viscosity, reduce the fluidity of oil, produce insoluble and corrosive substances, accelerate the deterioration of oil, affect the performance of gear oil, and even cause metal corrosion and rust.
4、良好的抗乳化性
4. Good demulsibility
齿轮油在生产过程中不可避免与水接触,油品吸收水分后被乳化,不仅会破坏金属表面的油膜使其失去润滑功能,还会使油品中的添加剂失效产生沉淀物,导致齿面磨损,所以齿轮油应具有良好的抗乳化性。
Gear oil will inevitably contact with water in the production process, and the oil will be emulsified after absorbing water, which will not only damage the oil film on the metal surface and make it lose its lubrication function, but also make the additives in the oil ineffective and produce precipitates, resulting in tooth surface wear. Therefore, gear oil should have good anti emulsification property.
5、良好的抗泡性
5. Good foam resistance
生产过程中,齿轮油因为搅拌易产生泡沫,如果放任不管,泡沫可能会一直存在。泡沫的导热性差,无法降低齿轮摩擦产生的温度,齿面过热使油膜破裂,泡沫的存在也影响新油膜的形成,一旦油膜完整性不够,就会使齿轮油失去润滑性能,造成磨损。良好的抗泡性可以保证齿轮油产生的泡沫较少并易于消散。
In the production process, gear oil is easy to produce foam due to stirring. If left unchecked, foam may always exist. The thermal conductivity of foam is poor, which can not reduce the temperature generated by gear friction. The overheating of the tooth surface causes the oil film to break. The presence of foam also affects the formation of new oil film. Once the oil film is not complete enough, the lubricating performance of gear oil will be lost, resulting in wear. Good anti foaming property can ensure less foam produced by gear oil and easy to dissipate.
6、良好的防锈防腐蚀性
6. Good rust and corrosion resistance
在水分和氧气的参与下,齿面及齿轮箱容易生锈,就需要齿轮油具有良好的防锈性。为了提高防锈性,一般添加硫磺盐或脂肪酸盐等防锈剂,而极压添加剂中的硫对铜极易产生腐蚀,就需要加入防腐蚀添加剂,这样可以在金属表面形成保护膜,防止腐蚀性物质侵蚀齿面。
With the participation of moisture and oxygen, the tooth surface and gear box are easy to rust, which requires the gear oil to have good rust resistance. In order to improve the antirust property, sulfur salt or fatty acid salt and other antirust agents are generally added. However, the sulfur in the extreme pressure additive is easy to corrode copper, so it is necessary to add anti-corrosion additives, so that a protective film can be formed on the metal surface to prevent corrosive substances from corroding the tooth surface.
除此之外,齿轮油还有粘附性、剪切安定性等性能,这些性能共同保障了齿轮油可以发挥其抗磨、润滑的作用。
In addition, the gear oil has adhesion, shear stability and other properties, which jointly ensure that the gear oil can play its role of anti-wear and lubrication.
选择合适的齿轮油,可以降低设备的润滑成本;帮助齿轮散热,起到一定的冷却作用;降低摩擦,减少工作噪音,减少功率损失,延长齿轮寿命;防止金属腐蚀或生锈;提高生产效率等。
Selecting proper gear oil can reduce the lubrication cost of the equipment; Help the gear to dissipate heat and play a certain cooling role; Reduce friction, reduce working noise, reduce power loss and prolong gear life; Prevent metal corrosion or rusting; Improve production efficiency, etc.
齿轮油在整个生产过程中都起到了不可忽视的作用,所以一个合适的齿轮油是必不可少的,但运行的过程中也要多加注意,避免异常状况的出现。
Gear oil plays an important role in the whole production process, so a proper gear oil is essential. However, more attention should be paid to avoid abnormal conditions during operation.
