近年来,不用键销而能使轴与轮毂牢固地结合的设计方法,又重新受到重视。本文介绍的辐射状碟形弹簧片(图1),就具备这一功能。这种弹簧片的内外径尺寸精度极高,装配时根据传递扭矩的大小,选用一定尺寸的簧片和片数,叠放在轴上或毂的孔中,当施加轴向压力时,簧片的外径变大,内径变小,能产生很大的径向夹紧力,用以传达扭矩。夹紧弹簧的内外径都经过研磨,张紧时不会损伤轴和毂的表面,而
In recent years, the design method of firmly coupling the shaft to the hub without the use of a key pin has received renewed attention. This article describes the radial disc spring (Figure 1), to have this feature. The inner and outer diameter of this spring is extremely high dimensional accuracy, the assembly according to the size of the transmission torque, the choice of a certain number of reed and the number of sheets, stacked on the shaft or hub hole, when the axial pressure is applied, the reed The outer diameter becomes larger, smaller diameter, can produce a great radial clamping force, used to convey torque. The inner and outer diameters of the clamping spring are ground and will not damage the surface of the shaft and hub when tensioned
