一种蜗轮蜗杆专用润滑脂及其制备方法
技术领域
本发明涉及润滑脂技术领域，具体涉及一种以高粘度精制矿油为基础油，以有机和无机混合皂为稠化剂，加入极压抗磨剂、抗氧剂、增粘剂而制成的蜗轮蜗杆专用润滑脂及其制备方法。
背景技术
对于减速机的蜗轮蜗杆的润滑，过去主要使用润滑油，存在几个缺点：
1.由于工作环境温度高，油粘度下降，易漏失，既污染了环境，又造成浪费，蜗轮蜗杆达不到润滑、防护的效果，造成蜗轮与蜗杆、轴承磨损严重，过早报废。
2.油使用寿命短，在高温遇水条件下，油很快发生乳化、变质、腐败，这就需要不断更换新油；使用成本上升。
近年，逐渐发展采用半流体润滑，要求产品即具有油的流动性，满足蜗轮蜗杆飞浸泡润滑的要求，又要有脂的高温性，能起到润滑、密封双重功效。
国内市场现有的蜗轮蜗杆润滑脂，是一种通用的半流体极压锂基润滑脂，可以替代齿轮油，满足一般蜗轮蜗杆的润滑、密封的要求。但是随着减速机行业的发展，对蜗轮蜗杆减速提出了更高的要求，相应对所需润滑脂品质要求很高，而现有的蜗轮蜗杆专用润滑脂在高温润滑性能、降低设备运转噪音、满足设备长的使用寿命方面达不到要求。
本发明的蜗轮蜗杆专用润滑脂具有高温润滑性、高粘附性，保证蜗轮与蜗杆运转有足够的油膜厚度，并能够有效降低运转噪音，精心挑选的极压抗磨剂大大提高了使用寿命，可以满足中高档蜗轮蜗杆润滑的要求。
