技术领域
本发明属于润滑油技术领域，具体涉及一种齿轮油及其制备方法。
背景技术
齿轮传动的主要特征为重载、低速、结构尺寸较大，而且齿面粗糙度较高，工作条件苛刻(如灰尘、高温、冲击载荷等)。齿轮可以传递很高的力矩，在启动、正常运转、停机期间通常处于混合摩擦状态，因而齿面承受极高的应力。齿轮的工况特点决定了所使用的齿轮油必须是粘附性极强的高粘度产品，工作温度范围宽，在冬、夏季均有很好的粘附性；具有极高的承载能力，高的抗磨损和抗极压性能；具备一定的油膜强度；具有良好的可喷雾性或具有良好的流动性能。
当前，市售的齿轮油产品普遍存在着极压润滑性能不足，防锈抗腐蚀能力不够，工作运行过程中会加速油品失效，齿轮磨损，减小寿命。
发明内容
为了解决现有技术存在的上述问题，本发明提供了一种齿轮油及其制备方法。所述齿轮油的极压抗磨性较好，粘度指数高，低温流动性好，防腐蚀性能和防锈性能较好，剪切稳定性较好。
