The results show that with the increase of the cone angles and the coefficients of friction in the certain range, the stress of the anchor ring can gradually decrease.
结果表明：随着锥角和摩擦系数在一定范围内增大，锚环的应力会逐渐减小；

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.
