带极压的齿轮油并不是哪里都能用


Release time:

2025-12-16

齿轮油的主要成分是基础油(矿物油或者合成油),外加少量添加剂。极压齿轮油(EP gear oils)常用于重负荷、有冲击性负荷的工业齿轮润滑,里面加入了极压添加剂(EP additives)。极压齿轮油一般含有硫磷极压剂,因此这类油闻起来味道比较大,有硫磷化合物的刺激味。工业极压齿轮油不能用于汽车齿轮,因为工业齿轮油的硫含量不符合汽车齿轮的要求。

许多极压齿轮油的极压剂在使用中会带来一些问题,在选用极压齿轮油之前,我们要对这些可能问题心中有数,避免可能引起的问题。下面为你介绍极压剂常见的局限性有哪些:

1、对铁金属表面的影响:极压添加剂会氧化铁金属的表面形成化学腐蚀,造成金属表面损坏,有些极  压剂对铁金属的腐蚀性较为严重,在选用前,应注意了解。

2、对黄色金属(含铜部件)的腐蚀:含铜部件接触极压齿轮油时,应注意这个问题(尤其在温度超过60℃时腐蚀作用明显),例如蜗轮蜗杆齿轮副。某些极压添加剂里的活性硫磷成分会对黄色金属造成腐蚀,购买时应查看油品说明书,其中有一项是关于铜片腐蚀性(copper strip corrosion)的(ASTM D130),级别如果是1a表明你可以放心了,这个级别说明油品化学惰性强,不容易和铜发生反应。而级别越高就越容易与铜发生反应(1b、2a),查看极压齿轮油对铜金属的腐蚀性等级。另外,如果油品商指出“不适用于黄色金属”或者“适用于铁金属”这类字样,那么油品就不适用于含铜部件。

3、硫磷极压剂在高温下的极压性能降低:温度上升到95℃时,硫磷极压剂的极压性能会受到影响,因此含有这类极压剂的极压齿轮油在高温下的使用受到限制。

4、与其它类型添加剂不相容:事实上,不同的油品都不应该混用。另外,在使用中,应该把极压剂和含锌抗磨剂区分开,硫磷极压剂与含锌抗磨剂不相容,因此这两类油和这两类添加剂都不宜混合。

5、含氯极压剂不能接触水:这类极压剂在有水的情况下,会形成金属腐蚀。使用这类极压齿轮油时应注意这一点。

6、不能滥用极压齿轮油:齿轮油有抗氧防锈型、极压型、复合型,一般的工况,使用抗氧防锈型可以满足要求。原则上,如果设备产家没有指明要求极压型齿轮油,那么不应自行使用这类润滑油。
