Description

一种铁路货车闸调器专用润滑脂及其制备方法
技术领域
本发明属于专用润滑脂技术领域，具体涉及一种铁路货车闸调器专用润滑脂及其制备方法。
背景技术
齿式联轴器是由齿数相同的内齿圈和带外齿的凸缘半联轴等零件组成，外齿分为直齿和鼓形齿两种齿形，所谓鼓形齿即为将外齿制成球面，球面中心在齿轮轴线上，齿侧间隙较一般齿轮大，鼓形齿联轴器可允许较大的角位移（相对于直齿联轴器），可改善齿的接触条件，提高传递转矩的能力，延长使用寿命。齿式联轴器在工作时，两轴产生相对位移，内外齿的齿面周期性作轴向相对滑动，必然形成齿面磨损和功率损耗，因此齿式联轴器需在良好润滑和密封的状态下工作。

（3）待皂化反应完成后，继续搅拌升温脱水，温度达到150-160℃时取样测皂基游离碱，合格后物料继续升温至190-200℃加入35重量份的防锈油进行稠化，并加入3重量份的硬脂酸进行搅拌，继续升温至215-220℃恒温15min，加入4重量份的二烷基二硫代磷酸盐，使釜内容纳物呈真容液状态并将润滑脂通过过滤器打入到调和釜内回流冷却；
（4）润滑脂在调和釜内搅拌回流冷却2-4h，搅拌降温至180℃时加入2重量份的聚异丁烯和5重量份的沥青，搅拌均匀后冷却并通过研磨机研磨、过滤、炼制成铁路货车闸调器专用润滑脂。
