在设计或制造O形密封圈钢模时,必须修正其公差,即±△d及±△D(见图)。它们之间如何补偿最佳,是我们设计与制造者值得探讨的。在工作中发现△D与△d之间有个简单的关系式:△d=-d/2D·△D
When designing or making O-ring dies, the tolerances must be corrected, ie ± Δd and ± ΔD (see picture). How to compensate for the best between them is something we design and manufacture worth exploring. In the work found △ D and △ d between a simple relationship: △ d = -d / 2D · △ D
