简述KTC切丝机传动特点。

答案

参考答案:

由德国HAUNI公司生产的KTC切丝机的主传动采用机械、液压传动,其主要特点有:1)刀辊与送料机构的切丝运动,分别由两个液压马达驱动,运动速度可在运转中无级调节,但调定的切丝宽度不变。2)通过调节无级变速器P.I.V的速比和改变切刀数量,切丝宽度可在0.1~3mm之间分段无级调整。3)刀片的进给为断续渐进式,进给量可无级调节。4)刀片进给机构采用空间曲柄连杆行星轮系结构,刀片的进给速度(次数)与刀辊转速成正比。5)刀片的进给速度与刀辊转速成正比。磨刀装置往复运动由刀辊主轴传递,其往复速度与刀辊转速成正比。

完形填空

There was a man. He had four sons. He wanted his sons to learn not to judge things too quickly. So he sent them each on a quest(探索)in turn, to go and look at a pear tree that was far away. The first son went in the winter, the second in the spring, the third in the summer, the youngest son in the fall. When they had all gone and come back, he called them together to describe what they had seen. The first son said that the tree was ugly ,bent and weak. The second son said no---it was covered with green buds and full of promise. The third son said it was laden with blossoms and they smelt so sweet and looked so beautiful. The last son disagreed with all of them. He said it was ripe and drooping(下垂 )with fruit, full of life and fulfillment.. The man then said to his sons that they were all right, because they each had seen but only one season in the tree’s life. He told them that they cannot judge a tree or a person, by only one season, and that the essence(本质) of who they are---- the pleasure, the joy and love that come from that life---can only be measured at the end (盖棺论定),when all the seasons are up.    If you give up when it is in winter, you will miss the promise of your spring, the beauty of your summer, the fulfillment of your fall. Don’t let the pain of one destroy the joy of all the rest.
