对单分度机构的要求是:经济、实用和高的加工精度。在单分度机构中,槽式分度盘式单分度机构用得较多。该机构结构简单,但主要不足之处是槽式分度盘制造复杂,需用专门的加工机床,价格昂贵(一个用于齿轮磨削用的槽式分度盘价格为1000至2000元人民币)。为了寻求较为经济的单分度机构,采用相当精度的齿轮来代替成本较高的槽式分度盘,以降低齿轮、花键等工件的磨削费用。本文着重从理论上分析,齿轮式单分度机构各主要构件的加工和安装精度,对
The requirements for a single indexing mechanism are: economic, practical and high machining accuracy. In the single indexing mechanism, the slotted indexing single indexing mechanism is more used. The structure is simple, but the main disadvantage is that the trough indexer is complicated to manufacture and requires a special machine tool, which is expensive (a slotted indexing plate for gear grinding costs 1000 to 2000 RMB) . In order to seek a more economical single indexing mechanism, a rather accurate gear is used instead of the higher cost indexing plate to reduce the grinding cost of gears, splines and other workpieces. This paper focuses on the theoretical analysis, the gear single-indexing mechanism of the main components of the processing and installation accuracy,
