一、导言纯粹的压配合和热配合的连结是仅仅利用两个相互连接件之间的摩擦紧固力来传力。许多年来,大家就已经知道了这种连结方式对于传递大力的可靠性。在很多情况下,当轴和外套之间的连结要能传递大的、冲击性的和方向变化的力的时候,这种连结方式还将是唯一可行的方式。但是,当连结件的组装和特别是拆卸会引起困难、个别零件容易因而发生损坏的时候,这种连结方式也常常不能利用。油压连结的作用与通常的压配合和热配合的连结并没有什么不同,只是它的组装和拆卸简便些,可 I. INTRODUCTION Purely press-fit and hot-fit couplings use only the frictional tightening force between two interconnecting pieces to transmit force. For many years, everyone already knew that this kind of connection to the delivery of strong reliability. In many cases, this connection will also be the only viable option when the shaft-to-sheath connection is to transmit large, impacting and directional forces. However, this type of connection is often not available when the assembly and especially the disassembly of the linkages can cause difficulties and the individual parts are easily damaged. The function of the hydraulic connection is no different from the usual press-fit and hot-fit connection, except that it is easier to assemble and disassemble
