Description

一种齿条表面固体润滑层
技术领域
本发明涉及齿轮、齿条领域,尤其涉及一种齿条表面固体润滑层。
背景技术
齿条为具有一系列等距离分布齿的平板或直杆,齿条也分直齿齿条和斜齿齿条,分别与直齿圆柱齿轮和斜齿圆柱齿轮配对使用。经齿轮传动与齿条传动相结合,尤其涉及直线传输时,常采用齿条齿轮的传动方式,具有运输平稳、步距较准、兼具载重的优点。为了防止齿条和齿轮的磨损、点蚀、胶合可提高其使用寿命,对于齿条和齿轮的润滑尤为重要。
现有技术中,为了提高齿轮和齿条的配合传动性能,常直接注入以润滑油或涂覆以润滑脂的方式,效果较好,然而显而易见的缺点是必须在润滑油或润滑脂用完前再次注入或涂覆,以持续润滑性能。更方便的方法是将齿条表面涂覆上一层润滑层,该润滑层具有显著的自润滑性能,能够供齿条和齿轮的啮合部位在较长一段时间内维持润滑。且为了适应不同程度的高温,目前市面上各种自润滑的材料的适用范围受到限制。
发明内容
本发明的目的在于提供一种齿条表面固体润滑层,使齿条表面保持较长时间润滑,不用添加润滑油/润滑脂的情况下提升齿轮齿条机构的综合性能,且能在高温、高强度作业下使用,克服现有技术中存在的问题。
为了实现以上目的,本发明的技术方案是:
一种齿条表面固体润滑层,包含以下重量份的组分:
MoS2 10-20份
WS2 5-12份
MoO3 6-15份
WO3 5-8份
CaF2 3-12份
Fe粉 8-15份
Cu粉 6-10份
Ni粉 3-5份
Cr粉 2-8份
MgO 1-7份
Al2O3 1-6份。
作为优选,所述Fe粉的粒度为45-55μm,所述Cu粉的粒度为50-60μm,所述Ni粉的粒度为50-75μm,所述Cr粉的粒度为50-60μm。
作为优选,所述所述MoS2的粒度15~25μm,WS2的粒度在10~25μm。
作为优选, 所述MgO为纳米MgO,粒径80~450nm,所述Al2O3为纳米Al2O3,粒径50~150nm。纳米氧化镁和氧化铝具有一般非纳米材料所没有的表面效应、量子效应等性质。
作为优选,所述Al2O3为γ-Al2O3。γ-Al2O3平均粒径小,具有显著的纳米效应。
本发明的有益效果在于:本发明配方简单、自润滑高效。金属粉末的混合起到类似自润滑合金的作用,而Mo、W的硫化物和氧化物本身是良好的自润滑剂,MgO既是纳米材料,又能够和WO3或MoO3反应而得到新的盐矿物,且增强自润滑;纳米氧化铝起到多重纳米效应,改变体系中的微观作用力。本发明设计耐高温、持久自润滑,适用于剧烈循环工况和高温的齿条自润滑场合,具有显著的高适用性和工艺灵活性。
