为帮助同学们搞好期末复习,将书第三篇机械传动部分的部分习题作解,供参考(限于篇幅着重概念题)。 第十二章 基械传动设计概论 12—1.在原动机和工作机之间为什么一般都要用中间传动机构? 答:按照工作机的运动形式和速度大小要求传递运动,即增、减速或转变运动形式。 12—3.若已知各级机械传动的传动比,传动效率,写出多级串联机械系统的总速比,总效率计算式?
To help students do a good job in the final review, part III of the mechanical transmission part of the problem solution for reference (limited to the length of the concept of space). Chapter 12 Introduction to the Basics of Mechanical Transmission 12-1. Why the intermediate transmission mechanism is generally used between the prime mover and the working machine? A: According to the movement form and speed of the working machine, it is required to transmit motion, that is, increase, slow down or change Form of exercise. 12-3. If you know the mechanical transmission at all levels of the transmission ratio, transmission efficiency, write a multi-stage series mechanical system total speed ratio, the total efficiency of the formula?
