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，联接机厂家， 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.
一个切向键只能传递一个方向的转矩，传递双向转矩时，联接机，须用互成120°～130°角的两个键。用于载荷很大，对中要求不严的场合。由于键槽对轴削弱较大 ，常用于直径大于100mm的轴上。
A tangent key can only transfer the torque of one direction. When the two-way torque is passed， the two keys of 120 to 130 degrees are required. An occasion for he**y load and no strict requirement. As the keyway is greatly weakened to the axis，联接机价格， it is often used on a shaft with a diameter larger than 100mm.
机用虎钳结构缺点及使用中的隐患。机用虎钳有结构简单、夹紧力大、操作和维护方便等特点。但由于其必须具有广泛的适用性和操作的便捷性，其螺母与丝杆之间、活动座与虎钳体之间存在着较大的配合间隙，导致在装夹一些加工精度要求较高的产品时难以达到要求。
The structural shortcomings of the machine vise and the hidden danger in the use. The machine tool has the characteristics of simple structure，联接机设备， large clamping force， easy operation and maintenance. But because of its wide applicability and convenient operation， there is a large gap between the nut and the screw rod， the movable seat and the vice body， which results in the difficulty of meeting some requirements when clamping some products with high machining accuracy.
