提高清筛机扒齿寿命的研究

A Study for Porlonging the Lifetime of the Teeth of Railway Ballast Cleaning Machine

提高清筛机扒齿的寿命是一个重要课题,我们研制的整体式曲线型旋转扒齿获得了较长的寿命,本文就此作了较全面的论述.通过测试,揭示了扒齿的失效机理和磨损特性,为合理设计扒齿提供了依据.

It's an important subject to prolong the lifelime of the teeth ofrailway ballast clearing machines This paper gives a comprehensivedescription of the rotational teeth of ietegrated curve--modelWe have developed,Which proves to be of a longer lifelime.Through tests the principle imvalidity of and wear character ofthe teeth are revealed and therefore prvide a basis for reasonabledesign of the teeth.
