sliding coefficient of friction

The deformation coordination equation of worm gear for rolling cone worm gearing is introduced, and the formulae of forces analysis and the rolling - and - sliding friction coefficient are given.

本文建立了滚锥包络环面蜗杆传动蜗轮的变形协调条件，给出了该种传动受力分析的计算公式以及蜗轮与蜗杆之间滚滑摩擦系数计算公式；

It is found that the friction coefficient increases with the increase of sliding velocity, and there is critical velocity.

试验发现，摩擦系数随滑动速度的增加而增加，存在临界滑动速度。

The result shows that in the ring-block sliding wear test, with time prolonging, the friction coefficient of all samples becomes more and more stable, and the mass wear loss increases.

结果表明：在环-块滑动摩擦实验中，随时间延长，试样摩擦系数均趋向平稳，质量磨损量均增长。
