13)在牛头鉋床中的推力,导轧的单位压力。参看[图二十八],曲柄梢的等速转动使摇杆A_0E_0绕A_0点摆动,同时摇杆的顶端在水平方向滑动,使牛头作直綫运动。在不损害强度情况下,传至牛头的力量称为刨削时的推力,其大小等於牛头运动的阻力。当计算牛头鉋床工作运动机构各另件时,我们应采用推力的最大值。 13) Thrower in a shaper, the unit pressure of the rolling. See [Figure 28], constant rotation of the crank tip rocker A_0E_0 swing around the A_0 point, while the top of the rocker slide in the horizontal direction, so that the head for a straight line of movement. Without damaging the intensity, the force transmitted to Tau is called the thrust when gouging and its size is equal to the resistance of Tau. When calculating the various parts of the shaper working movement, we should use the maximum thrust.
