3MZ3015型和3MZ309型超精加工机转位机构的主轴和夹盘采用了弹性套联接形式(图1),提高了转位性能,弹性套是一种新颖的联接元件,与一般的键联接、无键联接(压入联接或热压联接)比较,除了它接触面上没有键槽及尖角,不产生应力集中,承载能力高,定心性好及重量轻、轴向空间紧凑、装拆方便等优点外,尤鲜为人知的是,其相位可微量调节,具有变刚度的特性。现将其工作原理及联接计算简介如下。一、工作原理和比压由图2可知,弹性套在螺栓的轴向力作用下,其内外表面卸载槽受挤压而趋于收敛,内表面各环直径
3MZ3015 and 3MZ309 superfinishing machine indexing mechanism of the spindle and chuck using a flexible sleeve connection form (Figure 1), improved indexing performance, elastic sleeve is a novel coupling element, with the general key connection, No key connection (press-in connection or hot-press connection) Comparison, in addition to its contact surface is not keyway and sharp corners, does not produce stress concentration, high carrying capacity, good centering and weight, axial space compact, easy assembly and disassembly Advantages, especially fresh known is that its phase can be adjusted, with variable stiffness characteristics. Now its working principle and connection calculation is as follows. First, the working principle and the specific pressure can be seen from Figure 2, the elastic sleeve in the axial force of the bolt, the inner and outer surface of the unloading groove is squeezed and tends to converge, the inner surface of the ring diameter
