Description

一种高粘度矿物油基润滑剂装填工艺
技术领域
本发明涉及一种自润滑轴承加工工艺技术领域,特别是一种高粘度矿物油基润滑剂装填工艺。
背景技术
自润滑轴承以高强度耐磨合金材料为基体,其自润滑的实现方式主要有以下几种:通过在轴承与转轴的接触面涂布高分子材料而获得复合材料自润滑轴承;或者通过在轴承基体上加工若干排列有序、大小适当的孔穴,再向孔穴中嵌入固体润滑材料而获得固体镶嵌自润滑承轴;通过在轴承与转轴的接触面加工高强度的耐磨合金,并且使耐磨合金的表面光滑,从而获得双金属材料自润滑轴承。
中国专利文献CN 106763159 A记载的一种基于固体润滑剂的锌基合金轴承,是本发明申请人早前提供的一种具有较好的抗水性的自润滑轴承,其中记载了一种固体润滑剂,包括以下质量百分数的组分:石墨41.0~43.0%、二硫化钼1.7~1.9%、钙钠基润滑脂7.5~10.0%、和余量的黏度指数为115~125的高密度矿物基础油。现有技术中,上述固体润滑剂主要通过手工方式填充到轴承的孔穴中,上述作业方式生产效率低、劳动强度大,而且不便于控制固体润滑剂在每一个孔穴中的填充紧实度和填充量。
发明内容
为了克服现有技术的不足,本发明提供了一种高粘度矿物油基润滑剂装填工艺,适用于机械作业将特定组分的固体润滑剂以高黏度分散系的状态填装到轴承的孔穴中。
本发明解决其技术问题所采用的技术方案是:
一种高粘度矿物油基润滑剂装填工艺,包括以下步骤:
S1、将固体润滑剂均匀分散在挥发性分散剂中制得流动性润滑剂;
S2、将流动性润滑剂填装到润滑剂挤压罐中,通过润滑剂挤压活塞挤压流动性润滑剂,使流动性润滑剂注入润滑剂装填柱的轴向输送通道中,润滑剂装填柱的直径与自润滑轴承的内径相等,自润滑轴承的孔穴朝向轴线的一端开口,另一端封闭;
S3、将自润滑轴承套装在润滑剂装填柱上,润滑剂装填柱外侧同轴设置有圆环形的润滑剂装填槽,润滑剂装填槽通过润滑剂装填柱的径向输送通道连通轴向输送通道,使自润滑轴承的孔穴对齐润滑剂装填槽,轴向输送通道中的流动性润滑剂分布在润滑剂装填槽中,从而装填到自润滑轴承的孔穴中;
S4、将孔穴中填装满流动性润滑剂的自润滑轴承从润滑剂装填柱上取下并套装在轴承静置柱上,轴承静置柱的直径与自润滑轴承的内径相等,通过轴承静置柱的侧壁封堵住自润滑轴承孔穴的开口端;
S5、静置自润滑轴承,直至孔穴中的流动性润滑剂中的挥发性分散剂挥发掉,剩下固体润滑剂,然后将自润滑轴承从轴承静置柱上取下。
作为上述技术方案的进一步改进,步骤S1中,固体润滑剂包括以下质量百分比的组分:
石墨41.0~43.0%、二硫化钼1.7~1.9%、钙钠基润滑脂7.5~10.0%、和余量的黏度指数为115~125的矿物基础油;所述石墨和所述二硫化钼的粒径均小于等于50微米;
挥发性分散剂为质量百分数大于等于99%的乙醇,且固体润滑剂和挥发性分散剂的质量比为1:(0.3~0.4)。
与现有技术相比较,本发明的有益效果是:
本发明所提供的一种高粘度矿物油基润滑剂装填工艺,通过将固体润滑剂均匀分散在挥发性分散剂乙醇中,从而可以使固体润滑剂具有较好的流动性,可以通过管路挤压输送并填装到轴承的孔穴中,然后将乙醇挥发掉即可使固体润滑剂原组分正常发挥润滑作用。
且本发明针对特定配比的固体润滑剂分散系粘度较高的特点,优化固体润滑剂挤压输送方法,特别适用于填装粘度较高的固体润滑剂分散系,从而减少乙醇的挥发时间,提高固体润滑剂的紧实度。
具体实施方式
下面将结合具体的实施例来进一步详细说明本发明的技术内容。
本实施例所提供的一种高粘度矿物油基润滑剂装填工艺,包括以下步骤:
S1、将固体润滑剂均匀分散在挥发性分散剂中制得流动性润滑剂;
具体地,固体润滑剂包括以下质量百分比的组分:
石墨41.0~43.0%、二硫化钼1.7~1.9%、钙钠基润滑脂7.5~10.0%、和余量的黏度指数为115~125的矿物基础油;所述石墨和所述二硫化钼的粒径均小于等于50微米;
挥发性分散剂为质量百分数大于等于99%的乙醇,且固体润滑剂和挥发性分散剂的质量比为1:(0.3~0.4)。
S2、将流动性润滑剂填装到润滑剂挤压罐中,通过润滑剂挤压活塞挤压流动性润滑剂,使流动性润滑剂注入润滑剂装填柱的轴向输送通道中,润滑剂装填柱的直径与自润滑轴承的内径相等,自润滑轴承的孔穴朝向轴线的一端开口,另一端封闭。
S3、将自润滑轴承套装在润滑剂装填柱上,润滑剂装填柱外侧同轴设置有圆环形的润滑剂装填槽,润滑剂装填槽通过润滑剂装填柱的径向输送通道连通轴向输送通道,使自润滑轴承的孔穴对齐润滑剂装填槽,轴向输送通道中的流动性润滑剂分布在润滑剂装填槽中,从而装填到自润滑轴承的孔穴中。
S4、将孔穴中填装满流动性润滑剂的自润滑轴承从润滑剂装填柱上取下并套装在轴承静置柱上,轴承静置柱的直径与自润滑轴承的内径相等,通过轴承静置柱的侧壁封堵住自润滑轴承孔穴的开口端。
S5、静置自润滑轴承,直至孔穴中的流动性润滑剂中的挥发性分散剂挥发掉,剩下固体润滑剂,然后将自润滑轴承从轴承静置柱上取下。
上述实施例中的流动性润滑剂,粘度系数在70000 cP~95000 cP之间,流动性较差需要较大的压力才能将流动性润滑剂填装到自润滑轴承的孔穴中,不过流动性润滑剂含有的挥发性分散剂也较少,因此流动性润滑剂不易从自润滑轴承的孔穴中流失,且挥发性分散剂挥发也较快,特别适用上述工艺。
以上对本发明的较佳实施方式进行了具体说明,当然,本发明还可以采用与上述实施方式不同的形式,熟悉本领域的技术人员在不违背本发明精神的前提下所作的等同的变换或相应的改动,都应该属于本发明的保护范围内。
