摘　　要：在削匀机的动力分析,刀辊设计等问题中,切削力矩是个非常重要的量,它不仅受机器本身结构的影响,而且还与被削皮革的性状有关。本文通过大量的实验,比较深入地研究了削匀机切削不同的皮革时,刀辊切削力矩的变化过程以及它们同皮革削匀量之间的关系。同时也从机器运动学和动力学的角度对“跳刀”问题作了一定的分析研究。此外,本文还提出了切削过程中皮革被挤压时“临界压缩度”的概念并给出它与皮革厚度之间的关系。The cutting torque in the shaving blade cylinder is a significant paramter, relating to not only the structure and the dynamic charactristic of the machine but also the properties and the states of the shaved leather.In this artical, the changing course of torque in a cutting period has been discussed in ditail,and a linear relationship between the to rques and the leather chip thicknesses has been obtained by a number of shaving experiments for different kinds of leather.Meanwhile the concept on the critical compression ratios of the leathers has been also advanced here.finally,the more reason- able explanations about the shaving machine's“blabo jumping”are given with the researched results,it demonstrating the correct way to control the shaving process and avoild shaving defects.
