塑料制品压配联接设计

Design of Press Fit Joint for Plastics Parts

从生产实际出发 ,介绍了典型压配联接的原理以及设计应力、压出力、径向过盈量和热膨胀的计算方法。对压配联接的长期性能和温度变化的影响应该加以考虑 ,尤其对轴和毂材料不同时的压配联接。

According to practical production the principle of typical press fit joint and the calculation methods for design stress,pull out strength,diametrical interference and thermal expansion coefficent are introduced.The long term performance of press fit joint and the effects of temperature changes should be considered,especially when the material for axes differs from that of hubs.\;
