轴承PV值

EPW塑料轴承最大运行PV值为0.5N/mm2×m/s;由此决定轴承所承受的载荷与速度成反比,详情查阅图表EPW-1。

轴承的载荷、速度、温度

EPW塑料轴承可承受最大静载荷为60Mpa,在此载荷下轴承的最大压缩变形量参考图表EPW-2;轴承实际工作载荷略小于60Mpa,载荷还受到运行速度以及温度的影响,速度越快(Vmax:1.0m/s)会导致摩擦温度上升,而温度上升(Tmax: 90℃)会导致轴承的承载能力逐渐减弱,载荷随轴承工作温度变化情况参考图表EPW-3。

轴承的摩擦系数、磨损、轴材料

轴承的摩擦系数

图表EPW-4表明EPW塑料轴承的摩擦系数随着运动速度的变化影响较小,而图表EPW-5表明EPW塑料轴承的摩擦系数随着载荷的增加明显减小,在载荷超过20Mpa是逐渐趋于平稳;图表EPW-6表明EPW塑料轴承的摩擦系数受轴粗糙度的影响也相对较小;虽然如此,我们还是建议轴的表面不能太光滑,也不能过于粗糙,推荐使用轴的粗糙度为Ra0.3~0.6um。

摩擦系数μ0.09~0.200.090.040.04

磨损与轴材料

图表EPW-7表明EPW塑料轴承在2Mpa下做旋转运动时,磨损随着轴材料的变化较大;通过实验表明EPW塑料轴承在做旋转运动时比较适合用于硬铬轴,硬化钢轴和硬铬轴上用于EPW塑料轴承能获得良好的运行效果。图表EPW-8表明硬铬轴更适合用于高载荷下的EPW塑料轴承,随着载荷的不断增加,轴承的磨损速率却变化较小,图表EPW-8表明EPW塑料轴承在不同载荷下的差异。

吸水性

EPW塑料轴承在标准大气压中的吸湿率为1.3%,浸泡在水中最高吸水率为6.5%;由于高吸水率的特性,我们必须考虑此轴承的应用环境。

抗UV性能

EPW塑料轴承长久暴露在紫外线下颜色会发生褪变。材料性能基本都不会发生改变。
