In this paper, friction field distribution between sliver and pressure bar on a homebred drawing frame is analyzed, and on this basis, the best range of contactarc is deduced.
The effects of cutting area, contactarc length, the geometry of cutting face, back dip angle of PDC cutter and rock performance on force of PDC cutter breaking rock were simulated experimentally.
试验模拟了切削面积、接触弧长、切削面形状、切削齿后倾角和岩石性能对PDC切削齿破岩受力的影响。

The load assignment formula and the method of the double circular arc gear under the wiring error influence between the contact mark was introduced and inferred.
