过盈配合可用于齿轮和滑轮之类的组合传动零件。但当元件数目增加时,分析这些组合件应力的工作很复杂.如果用矩阵方程可使应力分析简化.用计算机求解矩阵方程很为方便.在机械传动装置中,通常把键,销和花键作为连接元件,将扭矩从传动轴传递给齿轮,滑轮、皮带轮及链轮。过盈配合也能用来传递扭矩。因为无须连接装置,省去了键槽,销孔及花键齿的加工,因而成本较低。过盈配合时,齿轮或链轮的装配孔径小于轴径,用压合方
Interference fit can be used for gear combinations such as gears and pulleys. However, when the number of components increases, it is very complicated to analyze the stresses of these assemblies. If matrix equations are used to simplify the stress analysis, it is convenient to use computer to solve matrix equations. In mechanical transmission, the keys, pins and splines As a connecting element, torque is transmitted from the drive shaft to gears, pulleys, pulleys and sprockets. Tight fit can also be used to transmit torque. Because there is no need to connect the device, eliminating the keyway, pin hole and spline processing, so the cost is lower. Interference fit, the gear or sprocket assembly aperture smaller than the shaft diameter, with pressure side
