齿轮的啮合原理和几何设计,按内容体系,可分为三个段落。第一个段落包括第1至第9节的内容,叙述了直齿园柱标准齿轮的啮合原理。其基本概念和基本内容是学好其它两个段落的基础。 对这部份内容的知识体系,首先给出一个总体框架,会使学习的目的性更加明确,思路更加清楚。 齿轮机构的主要用途是实现定角速比稳定连续传动。对于定角速比连续稳定传动这一问题的叙述,大致可分为以下几个层次。(1)一对齿廓啮合传动。如齿
Gear meshing principle and geometric design, according to the content system, can be divided into three paragraphs. The first paragraph includes sections 1 through 9, describing the meshing principle of spur gear standard gears. Its basic concept and basic content are the basis for learning the other two paragraphs. This part of the knowledge system, first of all, to give an overall framework, will make the purpose of learning clearer, ideas clearer. The main purpose of the gear mechanism is to achieve constant angular velocity ratio of continuous transmission. For fixed angular velocity ratio of continuous transmission of the narrative can be broadly divided into the following levels. (1) a pair of profile meshing transmission. Such as teeth
