如果轴承工作表面产生锈点,就影响轴承寿命,增大噪音;如其他部位产生锈蚀,则氧化物侵入轴承内部,会使锈蚀发展。所以在轴承的整个制造过程中,均存在复杂的防锈问题。现根据两、三年的工作实践,介绍于下。一、防锈材料根据仪表轴承要求旋转灵活、储藏期长、材料是合金钢与铜合金等的特点,选择的防锈油必须是:(1)低粘度薄油;(2)浅色;(3)容易清洗;(4)防锈期达1～2年;(5)适合钢铜两种金属防锈;(6)杂质少;(7)油封方便。我们从羊油镁皂、环烷酸锌、204-1防锈油、201防蚀脂、201防锈油、石油磺酸钡等缓蚀剂中试验选择,结果只有石油磺酸钡较适合于仪表轴承的防锈。最后经过基油和配比选择,确定使用101防锈油。其配方为:石油磺酸钡0.5%,变压器油99.5%。这种防锈油,我们进行了下列试验:
If the bearing surface rust, impact bearing life, increase the noise; If other parts of the rust, then the oxide invades the interior of the bearing, will rust development. So in the entire bearing manufacturing process, there are complex rust problems. Now based on two or three years of work practice, introduced in the next. First, rust-proof materials According to the requirements of instrument bearings rotating flexible, long storage period, the material is the characteristics of alloy steel and copper alloy, the choice of anti-rust oil must be: (1) low viscosity thin oil; 3) easy to clean; (4) rust-proof period of 1 to 2 years; (5) suitable for steel and copper two kinds of metal rust; (6) less impurities; We from the sheep magnesium soap, zinc naphthenate, 204-1 anti-rust oil, 201 anti-grease, 201 anti-rust oil, barium petroleum sulfonate and other corrosion inhibitor test results, only the results of petroleum barium sulphonate is more suitable Instrument bearing rust. Finally, after the base oil and the ratio of choice, to determine the use of 101 anti-rust oil. The formula is: barium petroleum sulfonate 0.5%, transformer oil 99.5%. This anti-rust oil, we conducted the following tests:
