The deformation coordination equation of worm gear for rolling cone worm gearing is introduced, and the formulae of forces analysis and the rolling - and - slidingfrictioncoefficient are given.
It is found that the frictioncoefficient increases with the increase ofsliding 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 frictioncoefficientof all samples becomes more and more stable, and the mass wear loss increases.
