求翻译：It is to be observed that the higher the bending angle, the more fluctuating the contact forces. The ball-totrack contact forces are higher than the ball-to-cage contact forces; this is more or less evident because: (a)the torque is transmitted by the ball-to-track contact and (b) the ball to cage efforts are not involved in the torque transmission, and the cage only maintaining the ball centres in the bisecting plane. For the balltocage contact, it is to be noted that the load at Pi,5 is higher than that at Pi,6, which is a consequence of Pi,1.4 lying on the other side of Pi,5 with respect to the bisecting plane as shown in Figs 2 and 4.是什么意思？
