键是一种标准件，通常用于联接轴与轴上旋转零件与摆动零件，起周向固定零件的作用以传递旋转运动和扭矩，楔键还可以起单向轴向固定零件。而导键、滑键、花键还可用作轴上移动的导向装置。 根据键的结构形式，键联接可分为平键联接、半圆键联接、楔键联接和切向键联接等几类。

The key is a standard part， which is usually used to connect the rotating parts and swing parts of the shaft and the axle to move the fixed parts to tran***it rotary motion and torque， and the wedge key can also play a one-way axial fixation part. The guide， slippery key and the spline can also be used as a guiding device for moving on the axis.

装夹后产品靠近活动钳口附近容易上翘、抬起，多次装夹一致性差。传统机用虎钳的螺旋副间隙较大，圣霖国际联接机报价，在使用中会产生较大振幅的振动；而活动座和虎钳体之间的滑动接触面较大，采用的间隙也较大。

After the clamping，圣霖国际联接机购买， the product is easy to and lifted near the movable jaw， and the c***istency of the clamping is poor many times. The spiral pair clearance of traditional machine vice is bigger， which will cause large amplitude vibration in use. The sliding contact between movable seat and jaw vice body is larger，圣霖国际联接机， and the gap used is bigger.

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***.
