试论机械设计中的一般公差问题

Dealing with the problems of the general tolerance in mechanical design

对于机器零件在功能上无特殊要求的要素,设计中可选择一般公差,既简化设计制造,又降低生产成本,提高产品互换性。

As for the essential factors machine parts have no special requirement functionally, the general tolerance can be chose in design, which not only simplifies design manufacture, but also reduces production costs and improves products complementarity.
