凡是在轴毂联接中不用键、花键或销时的联接，统称为无键联接。无键联接中我们介绍两个常用的型面联接和过盈配合联接。

The connection of no key, spline or pin in the hub connection is called the keyless connection. In keyless joins, we two commonly used type face joins and interference fit connecti.

型面联接：是利用非圆剖面的轴与相应形状的零件的毂孔配合而构成的联接，作为机械传动中的联接方式，型面联接相对于传统的键联接相比，具有联接强度高，没有应力集中，可以传递大扭矩且的同时也可以承受冲击载荷，并且对于一些大型机械装备来讲其拆装方便及维修便利。

is the hub hole type surface connection: the non-circular section axis and the corresponding shape parts with a connection, as the connection mode in mechanical tran***ission, compared with the traditional linkage type surface connection compared with connecting strength, no stress , can large torque and high efficiency at the same time it can withstand the impact load, and for some large mechanical equipment for its disassembly and convenient maintenance.

胜过机用虎钳的柔性虎钳，在装夹中能有效防止工件的翻转、倾斜，克服了机用虎钳因配合间隙大导致工件受力不均、加工发颤等现象；解决了现有轻型、精密工件加工时装夹不可靠的问题。

Flexible than vice machine vise, the clamping can effectively prevent the workpiece turning and tilt, overcome the machine vise for clearance to workpiece uneven stress, etc. to solve the phenomenon of processing tremble; the existing light and precision workpiece clamping reliability of the fashion。

机用虎钳的结构及原理。机用虎钳是机械加工中常用的装夹机构，其结构如图1所示。其主要工作原理：转动方头带动丝杠，在螺母（通过紧固螺钉固定在虎钳体上）的作用下，做螺旋运动的丝杠带动与之联接的活动座沿丝杠轴线方向来回移动。

The structure and principle of machine vise. Machine vise is a common clamping mechani*** in mechanical processing. Its structure is shown in Figure 1. The main principle: rotation of the lead screw nut in the square, (fixed in the vise body through a fastening screw) under the action of moving spirally driven screw connected with the movable seat to move back and forth along the screw axis.
