在机械制造中,过盈联接是使用得比较广泛的。过盈联接对工艺提出的主要要求是:(1)获得规定的尺寸精度和相互位置精度;(2)不降低联接件的表面质量及材料的物理机械性能;(3)保证规定的联接强度。过盈联接的常用装配工艺方法有压力装配或热套装配(加热包容件的装配方法)。在下列情况下要优先考虑热套装配:(1)受重载的联接(热套的联接强 In mechanical manufacturing, the interference connection is more widely used. The main requirements of the process for interference fit are: (1) to obtain the required dimensional accuracy and mutual positional accuracy; (2) to reduce the surface quality of the coupling and the physical and mechanical properties of the material; and (3) to ensure the specified coupling strength. Common methods of interference fit assembly process pressure assembly or thermowelling assembly (heating the assembly method of containing pieces). In the following cases to give priority to thermoset assembly: (1) by the heavy load connection
