市場前線｜提高可靠度的低成本軸承安裝方案

軸承廣泛應用於工具機、傳動系統和電動工具等行業的運動機構中。軸承的品質以及安裝工藝對於性能至關重要。目前，軸承安裝的主流是採壓入式干涉配合。因此，干涉量控制決定了軸承的工作效果。然而，生產過程中各種因素都可能導致干涉量超出規範範圍。任何一個干涉量超出設計範圍的干涉配合都可能導致軸承失效，工程師面臨的挑戰是如何以最低成本降低失效風險。本文將通過實驗設計 ( Design of Experiment, DOE）來探討 使用接著劑的「化學」解決方案的可行性。並配合使用漢高的Recal應用程式作為輔助設計工具，用來決定所需的最佳干涉量，並預估設計強度。

Bearings are used on the moving mechanism across the industrial segments covering the machine tools, powertrains, power tools etc. The bearing quality and a controlled mounting process are essential to ensure the best performance. Most of the bearing mounts are done interference press fit. Therefore, the interference control decides how the bearing will work. However, there are a variety of factors in the manufacturing process that will cause out-of-spec interference, then followed by the bearing failure, the challenge to engineers is how to reduce the chance of failure at the lowest cost. This article will investigate the feasibility of the adhesive bonded “Chemical” solution through a DOE (Design of Experiment) validation. The Recal, an APP developed by Henkel, will also be used as a supplemental design tool, to figure out the best interference at the preliminary design stage.
